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.
This allows all four wheels to move up and down independently, providing a smoother ride when, for example, going over bumps in the road.
Front-wheel drive is the most common type of drivetrain and offers several advantages. It is cheaper to manufacture (reducing the cost of the vehicle) and also lighter which helps improve fuel economy. Due to having the weight of the engine over the drive wheels it also benefits from increased traction.
The basic warranty of a car covers all aspects other than parts which are subject to normal wear and tear, such as windscreen wipers and brake pads. It lasts either a certain number of years or amount of kilometres driven.
Air suspension offers a smoother ride than the traditional steel spring suspension. It is also often adjustable, allowing you to raise or lower it based on the type of driving you are doing.
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.
