Engine type in car refers to the type of engine that powers the vehicle. There are many different types of car engines, but the most common are petrol (gasoline) and diesel engines

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.

Valves let air and fuel into the cylinders of a combustion engine. More valves typically make more power and are more efficient.

Responsible for delivering fuel from the fuel tank into your internal combustion engine (ICE). More sophisticated systems give you better mileage.

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 laden ground clearance is the vertical distance between the ground and the lowest point of the car when the car is empty. More ground clearnace means when fully loaded your car won't scrape on tall speedbreakers, or broken roads.

Distance from the centre of the front wheel to the centre of the rear wheel. A longer wheelbase is better for stability and also allows more passenger space on the inside.

The distance from the centre of the left tyre to the centre of the right tyre of a four-wheeler's front wheels. Also known as front track. The relation between the front and rear tread/track numbers decides a cars stability.

The distance from the centre of the left tyre to the centre of the right tyre of a fourwheeler's rear wheels. Also known as Rear Track. The relation between the front and rear Tread/Track numbers dictates a cars stability

It is the weight of just a car, including fluids such as engine oil, coolant and brake fluid, combined with a fuel tank that is filled to 90 percent capacity.

Rear headroom in a car is the vertical distance between the center of the rear seat cushion and the roof of the car, measured at the tallest point

Front headroom in a car is the vertical distance between the centre of the front seat cushion and the roof of the car, measured at the tallest point. Important for taller occupants. More is again better
