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.✕

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.✕

Valve configuration refers to the number and arrangement of intake and exhaust valves in each engine cylinder.✕

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

Bore is the diameter of the cylinder, and stroke is the distance that the piston travels from the top of the cylinder to the bottom. Multiplying these two figures gives you the cubic capacity (cc) of an engine.✕

The amount of pressure that an engine can generate in its cylinders before combustion. More compression = more power.✕

A device that forces more air into an internal combustion engine. More air can burn more fuel and make more power. Turbochargers utilise exhaust gas energy to make more power.✕

A device that forces more air into an internal combustion engine. More air can burn more fuel and make more power. Superchargers utilise engine power to make more power.✕

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

Specifies which wheels are driven by the engine's power, such as front-wheel drive, rear-wheel drive, or all-wheel drive. It affects how the car handles and also its capabilities.✕

The total amount of fuel the car's tank can hold. It tells you how far the car can travel before needing a refill.✕

Indicates the level of pollutants the car's engine emits, showing compliance with environmental regulations.✕

The maximum speed a car can be driven at. It indicates its performance capability.✕

A measure of how much air pressure a car faces as it moves through the air. It affects the fuel efficiency and the speed of the car.✕

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

The shaft that connects the steering wheel to the rest of the steering system to help maneouvre the car.✕

Specifies the type of mechanism used to turn the car's wheels, such as rack and pinion or recirculating ball. Affects the feel of the steering.✕

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 rate at which the car can increase its speed from a standstill. It is a key performance indicator.✕

The rate at which the car can increase its speed from a standstill. It is a key performance indicator.✕

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 .✕

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✕

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

The gross weight of a car is the maximum weight that a car can carry which includes the weight of the car itself, the weight of the passengers, and the weight of any cargo that is being carried. Overloading a car is unsafe as it effects handling and could also damage components like the suspension.✕

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