The displacement of an engine is the total volume of all of the cylinders in the engine. Measured in cubic centimetres (cc)

Power dictates the performance of an engine. It's measured in horsepower (bhp) or metric horsepower (PS). More is better.

The load-carrying ability of an engine, measured in Newton-metres (Nm) or pound-foot (lb-ft). More is better.

ICE engines have one or more cylinders. More cylinders typically mean more smoothness and more power, but it also means more moving parts and less fuel efficiency.

The number of intake and exhaust valves in each engine cylinder. More valves per cylinder means better engine breathing and better performance but it also adds to cost.

The component containing a set of gears that supply power from the engine to the wheels. It affects speed and fuel efficiency.

The system of springs, shock absorbers, and linkages that connects the front wheels to the car body. Reduces jerks over bad surfaces and affects handling.

The system of springs, shock absorbers, and linkages that connects the rear wheels to the car body. It impacts ride quality and stability.

The mechanism by which the car's steering operates, such as manual, power-assisted, or electric. It affecting driving ease.

Specifies the type of braking system used on the front wheels of the car, like disc or drum brakes. The type of brakes determines the stopping power.

Specifies the type of braking system used on the rear wheels, like disc or drum brakes, affecting the car's stopping power.

The distance from a car's front tip to the farthest point in the back.

The width of a car is the horizontal distance between the two outermost points of the car, typically measured at the widest point of the car, such as the wheel wells or the rearview mirrors

The height of a car is the vertical distance between the ground and the highest point of the car. It can decide how much space a car has along with it's body type and is also critical in determining it's ability to fit in smaller garages or parking spaces

The maximum number of people that can legally and comfortably sit in a car.

Distance between the centre of the front and rear wheels. Affects the car’s stability & handling .

Weight of the car without passengers or cargo. Affects performance, fuel efficiency, and suspension behaviour.

The total number of doors in the car, including the boot if it's considered a door. It affects access and convenience.
