New Car Test Drive Checklist
New Car Test Drive Checklist
|
What to Check |
|
1 |
Walk
Around |
|
|
Do a walk around of the car and observe the
styling, looks and overall appearance. |
|
|
Observe paint, panel gaps, door handles,
build quality, overall fit & finish etc. |
|
|
Check out the boot for space inside,
height, width and depth of it and how usable it is. If you carry large
luggage more often than not, try estimating if the boot would be able to
accommodate it or not. |
|
|
Open the doors (front and rear both) to
know how wide they open and how confidently they close. |
|
|
Check how comfortable getting in and coming
out of the car is, especially if you are going to be traveling with elder
folks. |
|
|
It's not just about your comfort, remember.
So, get in the rear and see if there's enough leg- and headroom. If you have
kids, take them with you to test out the space. |
|
|
Take a minute to see how you feel sitting
in the front seat. Get a sense for the space. |
|

Getting
Prepared for the Test Drive |
|
|
Before actually driving the car examine the
car properly. Explore compartments, push buttons and adjust dials. |
|
|
Play with the gadgets, see if the radio,
aircon and its vents and other controls like that for the wiper, horn etc are
easy to use. Connect your USB/iPod or play a CD to test the sound system (if
applicable). |
|
|
Check how comfortable the driving position
is, because you will be spending a lot of time stuck in jams in that
position. Check if you can adjust the steering wheel enough and get the seat
into a comfortable position. You should be able to reach the steering, the
gear lever and the foot pedals (clutch, brake and accelerator) easily. Also, check
if the instrument cluster is fully visible from that seating position. |
|
|
Check driver’s visibility. Since some cars
have low seating, or if the driver isn’t tall enough for the model, look for
the seat height adjustability. Good visibility is a must-have for safety
reasons. All ground checks are done and it’s time to drive now! :) |
|

The
Test Drive |
|
|
Go around the route suggested by the
salesperson once to get acquainted with the car. Also, if you are not happy
with the distance or the type of route, ask for a longer or different route. |
|
|
Never feel shy from asking for more; it’s
your hard earned money at stake here after all. Go around the route again,
and this time round, begin with feeling the steering. Twirl it left and right
to see how it feels and whether you enjoy it and how much effort is needed to
turn it quickly. |
|
|
Next, get a feel of the brakes. See if
these are too weak or strong. If these feel too powerful, it’s good and you
will get used to it and these brakes will need less effort to use. |
|
|
Check the mirrors - see if there's good
vision for the rear. See how much these adjust. |
|
|
Get a feel of the engine and the
acceleration. Rev the car to about 4000rpm to get an idea if the car is quick
or not; if it’s loud or quiet; and whether the engine sounds nice or coarse. |
|
|
Try driving at various speeds in different
gears, ranging from 20kph to 80-100kph (within legal speed limits) and note
cabin NVH (Noise, Vibrations and Harshness) due to traffic, wind and tyre
noise etc. |
|
|
Use the gearbox. See, if the clutch is
light to use or requires a lot of effort. Also, check if the clutch needs
slipping to get a move on. A worn out clutch can prove expensive later on.
Feel the gearshifts. Check if these are hard or easy. |
|
|
If you can manage to drive the car on a
rough road, try noticing the ride quality, suspension performance, cabin
rattles and squeaks etc. |
|
|
Try reversing into a parking space to check
you have good rear visibility. And change lanes while driving to check the
visibility at the sides. |
|
|
Check the AC. Switch on the AC when you are
driving at 80kmph and see the drop in the speed. Also check of the AC cuts
off, if the engine is revved hard and for how long. It's important to examine
how long it takes the car to heat up or cool down, especially on a hot summer
day. |
|
|
Observe AC fan / blower noise at various
speed levels. |
|
|
||

After
the Test Drive |
|
|
Discuss with the sales executive any
doubts/ concerns that may have come up during the test drive. The test drive
cars are not in perfect shape always and there is a chance that the issue you
observed is with this particular car and not in general. |
|
|
However, beware, if a problem exists in the
test drive car, it could probably show up in the car you buy sooner or later.
Also, note the odometer reading of the test drive car. |
|
|
Take the car brochure, price-list etc. the
sales person had brought along. Fill the feedback form, if the sales person
asks you to. |
|
|
Don’t be afraid to ask for another test
drive if you’re still unsure. |
What to Check in a
Test Drive for a Car?
Before you know how to take a test drive of a car, here are some
things you might consider checking:
·
Take a walk around and inspect the overall appearance of the
car.
·
Check panel gaps; door handles, overall fit and finish, build
quality etc.
·
Inspect the inside boot space, its dimensions etc.
·
Check how wide the front and rear doors open.
·
Ensure the car offers comfort during getting in and out.
·
Observe the leg and headroom in the car’s rear.
·
Ensure you get maximum comfort while sitting in the front.
After this preliminary check, you might want to consider some
further checks in detail before test driving the car. Here are the checks to
follow:
1.
Examine the various compartments, adjust dials and push buttons
in the car.
2.
Check the music system, aircon and its vents, wiper, horn etc.,
for their proper functioning.
3.
Inspect your steering wheel adjustability, driving position,
foot pedals, etc., and ensure overall comfort considering traffic congestion.
4.
Examine driver’s visibility, seat height adjustment etc. and
make sure the safety features are intact.
Now that you have completed the initial checks, you can proceed
to test driving your car. Nevertheless, during the test drive, you might
consider undertaking the following inspections:
·
Change the type of route and duration of the drive as per your
requirement to check the car’s performance.
·
Check your car’s braking efficiency.
·
Examine the engine and acceleration.
·
Notice the mirrors for proper visibility.
·
Drive your car at various speeds in different gears to check
cabin noise, vibrations and harshness, tyre noise etc.
·
Check how smoothly you can move the clutch.
·
Examine the riding performance on a rough road.
·
While reversing your car, check the rear visibility.
·
Inspect the aircon system or blower noises at various speeds.
Finally, after you complete the test drive, you can discuss any
doubts with the representative. In addition, if you are still unsure about your
choice, you can book another test drive.
Acceleration
Straight-line acceleration consists of three different tests: the
standing start (from which we pull all the zero-to-speed times), the
5-to-60-mph rolling start, and two top-gear acceleration tests (30 to 50 mph
and 50 to 70 mph). The rolling start is a C/D creation, in
which we creep along at 5 mph and then accelerate as hard as possible. This
test illuminates differences in powertrain flexibility. The larger the
difference between a 5-to-60-mph and a zero-to-60-mph run, the more lag an
engine has; this is particularly relevant today with the flurry of turbocharged
engines. Top-gear acceleration, in a manual-transmission car, where we simply
goose the throttle and don't downshift, highlights midrange power. In a vehicle
with an automatic, the transmission downshifts (and the times are much
quicker), so this metric represents a combination of transmission and engine
responsiveness. And that means the times between vehicles equipped with manual
and automatic transmissions clearly aren't comparable.
Standing
start. The quarter-mile. A race from A to B. No matter what you call it, this
is the test that most people care about. We test in street conditions, so
launch traction is low and not the level of stick you'd find at a local drag
strip. We also do not power shift, which is keeping your right foot pinned
while completing a shift. It is up to the tester to determine the best launch
technique, and this process can mean that some cars (for example, a
launch-control-equipped Porsche 911) require just two or three
launches to get the best possible time. Conventional automatics may only
require five launches. High-power, rear-wheel-drive cars equipped with manual
transmissions are the most time-consuming, and finding the sweet spot of
balancing wheelspin and clutch engagement (usually in the 3000-to-4000-rpm
range, but it varies depending on the car) may take 10 runs or more.
All of our
straight-line acceleration results are the average of the best run in opposite
directions, to account for wind. Ambient weather conditions—we record absolute barometric
pressure and wet- and dry-bulb temperatures trackside—determine how much power
an engine makes. Because of that, we also correct acceleration results to 60
degrees Fahrenheit at sea level. Cooler air is denser and contains more oxygen,
allowing the engine to burn more fuel and make more power. Similarly, high
barometric pressure produces more power than low pressure, and dry air has more
oxygen than moist air. All of our standing-start acceleration times also
include rollout, a short period of time (typically about 0.3 second) that we
subtract from the acceleration figures. It's a phenomenon that stems from the
physics of the timing lights at a drag strip, where a car can be rolling for 12
inches or more before the clock starts. We recently changed
our procedure to now use the industry standard 1-foot rollout.
When possible, we also measure
a vehicle's top speed. We often hit an electronic limiter during the
straight-line testing, but some cars' speeds are drag limited, meaning their
top speed is limited because of air resistance. Fewer cars are redline limited,
meaning their top speed is reached at redline in a gear—upshift and the car can't
go as fast. We don't test the top speed of every car because cars have gotten
ludicrously fast in the last 20 years and we don't always have access to a safe
place to do it.
Braking
Chassis performance testing answers two essential questions: how
short can a car stop, and how hard can it turn. Our standard braking testing
consists of six stops from 70 mph to zero. Five of them are done in close
succession, with the sixth stop coming after approximately a mile of cooling so
that we can roughly determine how well the brakes shed heat, which is otherwise
known as "brake fade." Stopping from exactly 70.0 mph is, obviously,
a very difficult thing to do. So, we stop from between 70.0 and 70.5 mph, using
a tape switch on the brake pedal so we know exactly when the brake pedal is
first touched. Then we correct the distance to a true 70.0-mph start based on
the average deceleration from that stop. To avoid any issues with a one-off
accomplishment, we report the second-best stop from the group of six as our
70-mph-to-zero distance. On high-performance vehicles, we also measure
100-mph-to-zero distance. The best sports cars wearing high-performance summer
tires can stop from 70 mph in the 140-foot range (we measured the new mid-engine Corvette at 149 feet), while
heavier trucks wearing knobby off-road tires, such as the Jeep Gladiator Rubicon, require
nearly 200 feet. When you need to stop in a hurry, those additional four car
lengths it takes to come to a halt can easily be the difference between an
elevated heart rate and a significant collision.
Maximum
Cornering (Skidpad)
Timing the lap of a car on a flat circle—we usually use a
300-foot-diameter circle, but we occasionally use a smaller circle out of
necessity—allows us to calculate the average lateral acceleration of a car. We
straddle the painted line that defines the circle with the vehicle's tires in
both directions and average the results, which we report as roadholding in
g-force. Fun fact: Almost every car turns a faster lap in the counterclockwise
direction, because the position of a driver on the inside of a car shifts less
load to the stressed outside tires. Cornering results range from 0.61 g for
a Mercedes-Benz G-class to
nearly double that for the grippiest sports cars.
Test-Vehicle
Prep
Just like any other researchers conducting a controlled case
study, we use a specific procedure for our test vehicles. Before a vehicle can
hit the test track, it must undergo numerous prepping protocols, ensuring that
every vehicle's performance is measured on a level playing field. By taking
these measures, we can consistently yield accurate real-world results and
confidently compare data from a recent test to one from years back.
From start to finish, the prep process is very thorough. All the
information is recorded on a template called a track sheet. When the test is
completed, the track sheet's data is stored in our database where it will live
on for eternity as reference material. First, the vehicle is carefully topped
off with fuel and weighed using our Intercomp wireless scales. The
corresponding weight of each corner is then recorded on the track sheet. This
is where the total weight, as well as front and rear weight distribution, will
be calculated and recorded.
Next, a technical assistant
scrutinizes every detail of the vehicle, both inside and out. During this
inspection, numerous data points are captured and recorded on the track sheet,
such as engine layout (front, mid, or rear), driven wheels (front, rear, or
all-wheel drive), transmission type, steering wheel turns from lock to lock,
and tire specifications. Correctly recording the tire information is a crucial
aspect of prepping a car for the track because tires influence nearly all
performance metrics, including cornering grip, braking, and launch traction.
Not only must the name, size, and any manufacturer-specific markings be noted,
but the tires must also be set to the manufacturer's recommended
cold-tire-pressure specification, which is located on the vehicle's door
placard or in the owner's manual. Finally, the engine oil level is checked to
ensure that it is at the recommended level. When all procedures have been
completed, the vehicle is finally track ready. With a rich history rooted in
instrumented testing, we take great pride in publishing test data that is
honest, accurate, and dependable.
Fuel
Economy and Driving Range
All light-duty vehicles are required by law to have their
fuel-economy estimates certified by the
U.S. Environmental Protection Agency (EPA). These city,
highway, and combined ratings are boldly listed on new vehicles' window
stickers and often used by manufacturers as advertisement fodder. Plug-in
hybrids and electric vehicles also receive
estimates for electric operation. Expressed in MPGe, these estimates are
intended to be an easy way to compare the efficiency of an electric to a
gasoline-powered car. But there is a
drawback to using EPA numbers that few people
realize: the agency actually does very few of its own tests. Surprise! The EPA
lists ratings that are mostly self-reported by auto manufacturers. Whether the
testing is performed by the automaker or the EPA, they are done inside on a
sort-of treadmill for vehicles that eliminates variables such as temperature
and traffic. These scientific methods provide the best way to directly compare
two vehicles. However, the EPA tests are not necessarily indicative of how
people drive in the real world, and the test cycles don't include speeds as low
as what's experienced in areas of dense traffic or high as those that tend to
be driven on U.S. highways. That's why we created our own uniform highway
fuel-economy test.
Highway Fuel-Economy Test
We run all our tests at a GPS-verified 75 mph on the same 200-mile
out-and-back loop on Michigan's I-94 highway. Our consistent procedure includes
a methodical fill-up process, following a specific route, using cruise control,
and setting the climate control to the same temperature (72 degrees auto). We
also correct for odometer error, and we don't test in heavy wind or rain or
with extra passengers. In the event we encounter too much traffic or unusual
conditions, we abort the run and try again later.
We follow the same procedure for electric vehicles and plug-in
hybrids, except for these, we have additional steps that include making sure
the battery is fully charged before starting and recording the kilowatt-hours
(kWh) needed to fill the battery after the drive loop. Plug-in hybrids also get
a highway EV range and MPGe economy for those miles. MPGe is calculated just
like miles per gallon of gas only using the EPA's equivalence factor of 1
gallon = 33.7 kWh of electricity to arrive at the result. For plug-ins that can't
hit 75 mph in electric mode, we instead first drain the battery and then start
the test in charge-sustaining (hybrid) mode. Since those plug-ins don't use any
electricity, their results are in miles per gallon rather than MPGe. Likewise,
we have to shorten our route for EVs that don't have the range to complete the
entire loop. We still give them an MPGe number, though.
Highway
Driving Range
The highway range figure we report is the maximum distance that a
vehicle can travel at 75 mph on a full tank of gas. We take the fuel economy
from our highway test and multiply it by the vehicle's fuel-tank capacity. For
example, the Honda
Accord 2.0T automatic averaged 35 mpg on our fuel loop and has a
14.8-gallon tank. This equates to an impressive 518 miles of range, but we
round down to the nearest 10-mile increment and publish it as 510 miles. That's
because when it comes to something that can strand you by the side of the road,
we believe it's better to publish conservative figures rather than distances
that are more difficult to achieve. A range figure under about 400 miles is the
threshold where fill ups can become annoyingly frequent.
Our process is different for electric vehicles and plug-in hybrids. For plug-ins, we simply note how many miles we get into our loop before the battery runs out of juice and the vehicle switches on the internal-combustion engine. EVs are more complicated, because as the battery charge gets really low they generally can't maintain highway speed and tend to go into a low-speed limp mode. (Plus, then we'd be stranded on the side of the highway.) And we also can't calculate range based on the energy put back into the pack after a test, because that would include the inefficiencies of the charging process. So we note the estimated range and battery state of charge from the trip computer every five miles. We then plot all of those points and fit a curve to project out to our range figure, again rounding down to the nearest 10-mile increment.
Observed
Fuel Economy
To give consumers an idea of how efficient a vehicle is in mixed
driving conditions, we track all fill-ups and mileage on our test vehicles. We
do the same with electric vehicles and plug-in hybrids, except for those we
track electrical energy (kWh) instead of gallons of fuel. This information is
documented for every model that is part of a comparison, long-term, or
instrumented test. However, we eliminate the miles recorded during track
testing and during our highway fuel loop. We also ensure that every odometer
reading is accurate to create a level playing field for all the cars we test.

The observed fuel-economy number we publish has variables such as
driving style (our staffers have heavier feet than most consumers, and some
more than others) and distance traveled. This means that comparing the economy
of one tested vehicle to another can be imperfect except for in our comparison
tests, for which all the cars are driven the same distances and in the same
conditions. So we consider our observed mpg as supplementary to the EPA
estimates and the results of our real-world highway fuel-economy test.
Cargo Space and Storage
The car-shopping process is both rewarding and exhausting,
sometimes even frustrating. People spend countless hours between dealerships
and websites narrowing down body styles, drivetrains, brands, and features.
While only you can decide between black and beige leather, we can take the
heavy lifting out of your car-shopping experience—literally. We measure every nook
and cranny inside the vehicle so that we can compare cargo and storage space
with its peers and so that you know which vehicle is going to fit the most
hockey bags, tool boxes, or Costco pallets before you even set foot on a dealer
lot.
Carry-Ons
Manufacturers provide scientifically measured cargo-volume numbers
that adhere to engineering standards, but those figures can vary depending on
which version of that standard the automaker is measuring to. These numbers are
also difficult to translate into real-world practicality. If Chevrolet states
that the Cruze hatchback has 25 cubic feet of space in its trunk, how do you
know if that's enough space to get your in-laws and their stuff home from the
airport? C/D's testing showed that the Cruze hatchback can fit five
pieces of standard carry-on luggage with all seats up, a figure that we think
is easier to visualize.
To perform this test, we use cardboard boxes measuring 9.0 by 14.0 by 22.0 inches, the maximum dimensions for carry-on luggage used by major U.S. airlines. Starting from the front row, we begin by moving the front seats to the minimum comfortable setting for a person that's 5'10" tall. Without removing anything we deem necessary for safe travel (headrests, spare tires, first aid kits), we fill the rearmost cargo area (either a sedan's trunk or the cargo area behind an SUV's or minivan's second or third row) with carry-on boxes, attempting to fit as many boxes as possible in the space. After reaching a maximum, we close the space, ensuring that the trunk or liftgate closes without interference—we will not force the door closed or bend any boxes. After the maximum capacity has been recorded, we fold the second and third rows and repeat. If seats fold in multiple ways (some cars have stowable seat bottoms, for example), we will determine the configuration that allows the maximum number of boxes. As with the trunk, all doors must close without interference. For models with various trims, we only retest vehicles with substantial differences in cargo area—such as those with a hybrid battery or a different seating configuration. For pickup trucks, we only test the enclosed space. Our current champ is a Ford Transit Cargo Van with 188 boxes, while a BMW i8 holds just one.
Ping-Pong
Balls
Have you ever situated yourself in a new car only find out that
there isn't enough space for your phone, sunglasses, wallet, makeup, chewing
gum, purse, and napkins? It's difficult to estimate how one car's interior
storage space compares to another's. This is why we devised our ping-pong-ball
test. By filling interior storage pockets with ping-pong balls, we can
objectively show how vehicles measure up to their competitors.
To perform this test, we remove everything from the cubby, such as
owner's manuals or removable storage trays, as these could reasonably be
relocated should an owner need to maximize a particular storage space. For open
bins, we add ping-pong balls arranged at random until the bin or cubby is full.
An open cubby is considered full when the balls reach a level where no ball is
more than halfway above the top edge. For closed compartments such as the
glovebox or center console, the enclosure must be able to latch closed with no
resistance from the ping-pong balls. At that point, the total number of balls
is recorded. Every defined storage space in the vehicle is counted, including
door pockets and underfloor spaces but excluding seatback map pockets and door
handles that fit less than six balls.
Lift-Over
Height
While high seating positions and ride heights are all the rage,
they often bring high cargo openings. We measure this height—to the nearest
tenth of an inch—to show how high an object must be lifted in order to place it
in a trunk or cargo area. For sedans this usually means the middle of the trunk
lip, and for SUVs and hatchbacks this typically means the carpeted part of the
load floor. If a vehicle has an adjustable suspension with a loading or parked
setting, we will test at both heights. When testing pickup trucks, we measure
to the surface of the open tailgate.
Visibility
and Seating Height
In an automotive market experiencing the rapid proliferation of
the crossover as well as the resurgence of trucks and SUVs, seating height has
never been a more scrutinized metric. As people continue gravitating toward
larger vehicles with higher seating heights, this measurement—which we
determine by measuring the distance from the driver's hip-point (or H-point) to
the ground—will undoubtedly become increasingly important to prospective
buyers.
Simply put, the H-point is the theoretical location of an
occupant's hip joint in a vehicle's seat, and it's determined using the SAE
International engineering organization's aptly named H-point
machine (HPM). The HPM is a plastic and steel human-shaped device designed to
mimic a 50th-percentile male (69.1 inches tall and weighing 172
pounds). The H-point could be considered the starting point when designing an interior,
because it influences many aspects such as roof height, seating height,
collision performance, outward visibility, interior packaging, and even the
door apertures.
To find the H-point of a car, we set the driver's seat to the
middle of its vertical and horizontal travel, giving us a consistent location
from which to start each of our tests. Next, the HPM is assembled in the seat.
Once the HPM is settled and level, it indicates the H-point with crosshairs
located on the side of the device. We verify seating height using a floor jack
and a laser level, by lining up the laser with the crosshairs and a level
yardstick. It is interesting to note that the H-points of a segment usually
fall within a fairly tight range—usually within one to three inches of each
other,—except for the SUV and truck segments, where it can be as much as five
to 10 inches.
MICHAEL SIMARICAR AND DRIVER
The HPM is a highly versatile instrument; besides its obvious use
for locating the H-point, we also use it to measure outward visibility. By
mounting a laser to the "head" of the HPM, we measure the horizontal
obstruction of each roof pillar in relation to the driver's sightline, measured
in degrees. We subtract the obstructed portions from 360 degrees, allowing us
to calculate the amount of unobstructed outward visibility.
We also measure how much of the roadway in front of and behind the
vehicle is obscured by the car itself. First we measure the distance in feet
that is blocked by the hood, then we make the same measurement in feet for how
much of the roadway can't be seen when looking over the trunk or hatch through
the rearview mirror. The results aren't always intuitive and are heavily
dependent on the vehicle's styling. For example, the 2019 Honda Accord has an
abnormally long obscured rear view of 138 feet (the Camry's is half as much),
while the 2020 Kia Soul has only 21 feet blocked to the rear because it is more
upright and doesn't have a trunk protruding off the back of the vehicle.
Center-of-Gravity
Height
A car's center of gravity (CG) is the hypothetical point in a
vehicle that is equivalent to the average location of all of the masses of the
individual components, and it's important because it directly influences a
car's dynamic traits. The lower it is, the better. A low CG reduces the load
transfer when cornering and thus limits body roll while improving transient
behavior. Beyond the implications for ride quality and handling, it also
reduces the possibility of a rollover incident. Low-slung sports cars, which
are painstakingly engineered to carry the majority of their weight very low to
the ground, generally have a very stable and confident feeling through corners,
whereas SUVs and tall trucks tend to exhibit more body roll and can feel tippy
in the same situations.
To calculate the CG, we first measure the height of the wheel
centers and weigh the vehicle using four individual scales (one per wheel) on a
perfectly level floor. We calculate the longitudinal location of the center of
gravity using the static weight distribution and the wheelbase (the distance
between the front and rear axles). The heaviest axle of the car is then lifted
and positioned on blocks, which are 17.9 inches tall, and the non-lifted axle
is weighed again.
The increase in the weight on the static axle provides the
critical variable to solving a trigonometric equation that determines the
height of the vehicle's center of gravity. For the mathematically minded,
we've detailed
this in more advanced language here.
It should be noted that we don’t measure the center-of-gravity
height for every vehicle we review. We generally perform this test on
performance-oriented cars, as this type of data is of greater interest for them
than for mainstream sedans, crossovers, and pickup trucks.
Infotainment
One of the critical characteristics that influences whether or not
an infotainment system is a chore to use is how much lag it has to inputs from
the touchscreen, control knob, touchpad, or other method of control. To measure
this, we use a GoPro camera to record interactions with the infotainment
system, measuring the time it takes for the system to respond to a number of
commands, such as from the home screen to each individual menu (e.g.,
navigation, radio, media, settings). We then average all of those times
together to arrive at an overall response-time figure for an infotainment
system. They vary widely; the best, such as Chrysler's
Uconnect, are below 0.3 seconds while the most laggy systems, such as
Mazda's, take more than a second to respond. As automakers are constantly
tweaking the hardware and software running the infotainment, we record the
software version of each car we test.
In addition to measuring response time and noting the many
features that make up an infotainment system—including the increasingly
popular Apple
CarPlay and Android
Auto—we also measure the output of each USB port in a vehicle, as more
juice means quicker charging time for the various electronic devices we can't
live without today. Here, too, the results vary considerably, from 2 amps of
current or more for the best ones to under 1 amp for the worst, which can be
barely enough to maintain a phone's state of charge if the screen is on and
being used to run a navigation app.
Safety
and Warranty
Safety is one of the few areas in which C/D relies
on outside testing to inform our ratings. Two agencies, the National Highway Traffic
Safety Administration (NHTSA) and the Insurance Institute for
Highway Safety (IIHS), perform crash tests on cars in the United
States. The ratings those agencies produce, which are found on window stickers
in dealerships across the country, form the backbone of our safety ratings.
When a car hasn't yet been tested by either agency, we don't assign it a safety
rating.
That's not to say that we don't perform our own subjective
evaluations of available safety equipment. When cars are equipped with
active-safety technologies, we leave them engaged during our test drives and
note whether they perform well or are intrusive. We also keep a rear-facing
infant seat handy to test out the ease of child-seat installation in any given
car. We're checking to see how easy it is to access LATCH anchors, whether
there's space for a rear-facing seat behind a comfortably adjusted front seat,
and whether the child seat sits level without the aid of bolsters or other
extra equipment. Finally, we collect data on the availability of a spare tire
and evaluate backup-camera operation.
Taken with the crash-test data, all of this information helps to
provide a picture not only of a car's safety credentials, but also of how easy
it is for buyers to opt into a model with desirable features. Safety is one of
only a few categories in which our ratings are given on an absolute scale
rather than determined in relation to a vehicle's direct competitors. If a
compact sedan needs nine seconds to reach 60 mph but tracks closely with its
key rivals, we won't knock it in our ratings. But a poor crash test result is
bad news, even if the competition performs similarly.
Warranty
Most of the cars we test come to us as loans from automakers, so
there's not much room to test the practical benefits of any given warranty.
However, our long-term
test cars, which stay in our stables for 40,000 miles, provide an opportunity
to become acquainted with the coverage and service offered by various brands.
To rate warranties, we compare the lengths of coverage periods and note whether
extras such as regularly scheduled maintenance are included or whether there is
a hybrid-specific warranty. We typically award the highest ratings to cars with
the longest coverage periods and deduct points when a company falls short of
its direct competitors or fails to offer a feature that others in its class
provide.
Editors'
Observations
Lest you think our editors simply take a spin around the block
before sounding off about a car's build quality, comfort, and driving dynamics,
we've created a step-by-step process for capturing and organizing our
impressions. We call it the editor's observation sheet (EOS), and this form
allows our editors to perform exterior and interior walkarounds while
collecting more than 170 individual observations using an iPad or laptop.
Upon starting a new EOS, the editor starts by recording the year, make, and model of vehicle that is under scrutiny as well as its trim and powertrain specifics. The exterior walkaround is next, and paint quality is noted, as are exterior features and panel fit. Next, the editor moves inside to evaluate the cabin, which is where the majority of the observations are made. Some items on the EOS are simply for information gathering, such as cupholder and USB count and port locations, but categories such as material quality, ergonomics, and infotainment usability are rated on a five-point scale, with notes made for each item that will later help the editor when writing the review. Additionally, a rear-facing infant seat is installed in the back seat and the editor evaluates the ease of this process. Then, on a thorough test drive, the editor makes notes in the performance and driving section, including subjective observations about the steering, handling, braking, and powertrain.
Once complete, this EOS evaluation is uploaded to our database and
saved for future use, both for the review of this subject vehicle and for
subsequent reviews of its competitors in which this vehicle can be used for
reference.
Overall
Ratings
When compiling our reviews, we assign ratings on a ten-point scale
to every car, truck, and SUV. In general, we determine the ratings based on the
car's results in our extensive testing, but also based on our subjective
evaluations after driving and spending time in the car.
We evaluate a car only in comparison to its competitors. We won't
knock a minivan for needing more time to complete a quarter-mile than a
supercar does, for instance. A hybrid that earns 40 mpg on the highway may be
derided, while a crossover will earn praise for topping 30 mpg. In certain
instances, though, we rate cars based on the overall market. Poor crash-test
scores, for instance, are not overlooked simply because the rest of the class
has also struggled. Because opinions can vary among our staff, we discuss
(argue) before a core team finalizes them, to ensure that no rogue opinions can
unfairly raise or tank a vehicle's score.
