A petrol (gasoline) engine offers several advantages over diesel. For example the engines tend to be lighter and cheaper than their diesel counterparts. Petrol engines also tend to have higher horsepower, and the fuel is more readily available.
This allows all four wheels to move up and down independently, providing a smoother ride when, for example, going over bumps in the road.
Rear-wheel drive benefits from increased traction when accelerating, as the weight of the vehicle shifts to the rear over the drive wheels. The weight of the car is also more evenly distributed, resulting in improved handling.
The CO2 emissions of the car, measured in grams per kilometre. A car with less emissions is better for the environment.
Four-wheel drive is a system where torque is distributed to all four wheels of the vehicle. It is beneficial in some circumstances such as providing increased traction in tricky weather conditions, but is most suited to off-road driving.
Hybrid cars run on a mixture of petrol (gasoline) and electric power. They offer several benefits over traditional petrol-powered cars. For example they produce less CO2 emissions, and due to their fuel efficiency they are often cheaper to run.
