Departure angle

Departure angle: The angle between the ground and a line running from the rear tyre to the lowest hanging point directly behind it, which is usually the rear bumper or trailer hitch. It indicates the ability of the vehicle to exit a steep incline without any damage to the rear bumper.

Denver boot

Denver boot: Denver boot is also called wheel clamp, it is a locking device which wraps around the wheel of a vehicle to immobilize it.

De dion axle

De dion axle: De dion axle is invented by Count de Dion, the axle is used to achieve independent suspension-of a live axle.

Dampers

Dampers: Commonly called shock absorbers, their function is to dampen i.e., absorb the oscillations of the suspension springs.

CVT

CVT: It is an automatic transmission that can select any desired drive ratio within its operating range. In other words, it is an 'infinite speed ratio' transmission.

Curb weight

Curb weight: The weight of a vehicle without passengers or payload, but including all fluids (oil, fuel, coolant, etc.) and standard equipment or accessories. Sometimes written also as 'Kerb weight.'

Crossover SUV

Crossover SUV: An improved version of SUV having light weight and better fuel efficiency, now being produced on a unibody architecture, i.e., frameless construction. However, these compromise off-road features and load capacity, due to which not recommended for off-road purpose like an ordinary SUV.

Coupe

Coupe: A car with only two doors and a hard top. The SAE standard J1100 defines it as having less than 33 cubic feet (934 litres) of internal volume.

Cornering power

Cornering power: The side force sustained per unit slip angle.

Cornering force

Cornering force: The force produced due to turning of the wheel to balance the side thrust.

Cornering

Cornering: The ability of a vehicle to travel a curved path.

Constant velocity joint

Constant velocity joint: Special universal joints wherein the fluctuations in the speed of the driven shaft at very large angles are completely absent. A common example of this is the Rzeppa joint.

Compensation of brakes

Compensation of brakes: It is the process of ensuring equal braking effect at all the wheel in spite of unequal lining wear etc. Appropriate mechanism to achieve this is called 'compensator' or 'equaliser'.

Combined angle

Combined angle: It is the angle formed in the vertical plane between the wheel centre line and the king pin centre line (or steering axis). It is also called 'included angle'.

Coast-by noise

Coast-by noise: The external noise generated by a passing car with the engine switched off. It is measured using standard procedures.
