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. | |||
Wide angle camera allows the driver to see well to each side from the very rear of the car when pulling out of parking spaces or side streets. A second selectable view. | |||

Wipers automatically turn on and adjust their speed based on input from a rain sensor. | |||
Vents at aft end of center console, in B-pillars, and/or in ceiling. | |||
Maintains set temperature in rear passenger area by providing heated or cooled air through vents in the center console, B-pillars, and/or ceiling. Replaces and includes value of rear air vents with manual controls. | |||
Ducts under front seats direct heated air to the second row. | |||
Drivetrain | |||
Selectively applies postive or negative torque to the wheels to counteract understeer and help rotate the car through a turn. | |||
Engine / Motor | |||
Triple level charger, fastest charge times with 220V source. | |||
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. | |||
Hitting a button extends the permitted range of the battery pack. | |||
When braking or coasting, a radar sensor scans traffic and adaptively brakes to maximize energy regeneration. | |||
Paddles on the steering column select different levels of energy regeneration during braking. | |||
