Brakes, Airbags, and Other Safety | ||||
Rear disc brakes. | ||||

If active, automatically move forward when the vehicle is rear-ended. Note: becoming less common. | ||||
Only listed when pricing a single model because insufficient data for all cars. | ||||
Automatically pulse the brakes in hard stops to prevent wheels from locking up, making it possible to brake and steer at the same time. | ||||
Mirror-mounted lights indicate when another vehicle is in a blind spot. | ||||
When a panic stop is sensed, fully applies the brakes. | ||||
Warns of traffic coming from either direction when vehicle is in reverse, to prevent accidents when backing out of parking spaces. | ||||
Alerts driver when approaching the preceding car too quickly. | ||||
Mandatory, in all cars. | ||||
Torso-level front row airbags, usually contained in the seats. Many also protect the head, but not as well as side curtain airbags. | ||||
Alerts driver when the vehicle seems to be wandering out of the lane. | ||||
Beeps signal distance to object behind vehicle. Parking aid. | ||||
Only listed if not standard on all trims. No value because no way to compare across models. | ||||
Prepares brakes (and sometimes also seat belts) for use when radar detects an imminent collision. Might also move seats and close windows. Early Lexus system used laser. Since automatic braking became common it has been unclear which models have this feat | ||||
Rearview camera connected to display screen on the instrument panel. Often requires navigation system. | ||||
Airbags contained just above the window level. Except in cars without a rear seat usually cover first and second row. | ||||
Selectively applies the brakes to prevent excessive understeer or oversteer (spinning). | ||||
Two types: a warning light when a tire is low on air and a pressure readout for each tire. | ||||
When a drive wheel slips, it is braked and/or engine power is reduced, restoring traction. | ||||
Cargo Management | ||||
Usually part of an overhead console. | ||||
Usually concealed behind a stowed armrest. Enables long items like skis to be carried without folding the rear seat. | ||||
Climate Control | ||||
Automatically recirculates interior air when pollution is detected in outside air. | ||||
Maintains set temperature in front row. Requires air conditioning and does not include its value. | ||||
Temperature can be separately set for left and right sides of the passenger compartment. Requires air conditioning and does not include its value. | ||||
Filters exterior air before it enters the passenger compartment. No default value because most cars have them, even in cases where they're not in the official list of features. | ||||
Ionizes air to clean it. Might create high levels of ozone. | ||||
Wipers automatically turn on and adjust their speed based on input from a rain sensor. | ||||

Ducts under front seats direct heated air to the second row. | ||||
Only listed when pricing a single model because insufficient data for all cars. | ||||
Time between wipes can be precisely adjusted. | ||||
Drivetrain | ||||
When one rear wheel spins, the differential locks up, sending power to the wheel with better traction. | ||||
The center differential can be manually locked using a button. Only for use at low speeds on loose surfaces. Engaging low range (where available) usually locks the center differential automatically. | ||||
Unlike a conventional differential, a Torsen mechanically shifts torque to the wheel with the most traction. Unlike a conventional limited-slip differential, it doesn't have to lock to do this. | ||||
Exterior | ||||
Side skirts and possibly a front air dam and rear apron. | ||||
Increasingly often these are not actually connected to the exhaust. | ||||
Only listed if a second, smaller spoiler is also standard or optional. No additional value because no way to compare across models. | ||||
