Homelink. | ||||
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. | ||||
Small external cameras provide a top-down view all around the vehicle, to reduce blind spots while parking. | ||||
If collision detection system senses imminent collision, applies moderate braking. | ||||
Automatically brakes car to avoid low-speed collisions. | ||||
Mirror-mounted lights indicate when another vehicle is in a blind spot. | ||||
When a panic stop is sensed, fully applies the brakes. | ||||
Warns when driver is drowsy and needs to pull over. | ||||
Applies the brakes to a slipping drive wheel to transfer torque to the other side, simulating the effect of a limited-slip differential. We haven't identified all applications, often implied by traction control. | ||||
Alerts driver when approaching the preceding car too quickly. | ||||
Mandatory, in all cars. | ||||
Selectively applies the brakes to maintain a slow, steady descent on off-road downhill slopes. | ||||
Applies the brakes to hold the vehicle in place on an incline. Incomplete data, so only displayed when pricing a single vehicle. | ||||

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. | ||||
Can be driven deflated for about 50 miles. Usually harm ride quality. Cars with these often have no spare tire. | ||||
Uses the brakes to channel torque to the outside wheels and counteract understeer. Similar to stability control, but proactive, and acting to improve cornering performance rather than prevent loss of control. | ||||
When a drive wheel slips, it is braked and/or engine power is reduced, restoring traction. | ||||
Additional features for stability control, such as performance calibration. | ||||

Drivetrain | ||||
When one front wheel spins, the differential locks up, sending power to the wheel with better traction. | ||||
Engine / Motor | ||||
Automatically cuts off the engine when the vehicle is stopped and restarts it when the driver lifts off the brake pedal. Not listed for hybrids, where it is generally part of the powertrain system. | ||||
Valves open in the exhaust at high rpm and/or during brisk acceleration, for power boost and/or richer sound. | ||||
