They are rear wheel drive.
the rear wheel drive ones
All cars can be turned into a non front drive car.
the gas is ignited in the engine creating a small explosion a small scale) pushing the cylinder upwards turning a wheel which connects to the wheels
You mean, what cars don`t come with front wheel drive. Most to-day are FWD.
An electric fan is needed on front-wheel drive cars
Front wheel drives are cheaper to build and much lighter,due to extra parts that go into building a rear wheel drive car.Four cylinder engines can deliver more power through the shorter drive axles as opposed to a longer drive shaft to the rear wheels.They are more stable and more fuel efficient.Since the government set standards on the fuel mileage of passenger cars,every ounce of weight taken off of a vehicle is important.
No, not feasibly. Front wheel drive cars typically have a transverse engine (as opposed to a longitudinal engine found in rear wheel drive cars) and a transmission with a different output location that that found on a rear wheel drive car... I won't say such a conversion is impossible, but it's highly impractical.
No
The benefit of driving 4 wheel drive cars is that you have the option to engage or disengage the four wheel drive when you need to. Four wheel drive is great on low traction surfaces (off road, snow, etc.).
Either a transverse engine for front wheel drive cars (and the occasional rear engine, rear wheel drive car), or a longitudinal engine for front/mid-engine, rear wheel drive cars.
You can. However, you have to buy the correct type. Rims made for real wheel drives typically do not fit front wheel drive cars. You have to find rims made for front wheel drive cars. Some stores simply do not carry them.
