They are rear wheel drive.
Yes, assuming the car has four wheels, four-wheel-drive is the same thing as all-wheel-drive. Not always, four wheel drive provides a positive lock between the front and rear axles. All wheel drive has a differential between them most of the time.
there are four wheel drive's,small cars,monster trucks and high cars.
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.).
Yes, there are hybrid cars that offer four wheel drive. The Ford Escape offers the hybrid model in four wheel drive. This car is a fuel economy and environmentally friendly car with four wheel drive.
Four wheel drive vehicles usually tend to be in the SUV or light truck class, although All Wheel Drive - which transfers power to the remaining wheels when a drive wheel loses traction - is a more often used system on passenger cars.
differential problem
The best rated four wheel drive (also known as all wheel drive) cars are Subaru Impreza, Ford Fusion, Acura RL, Toyota Sienna, Sabura Outback, as well as others.
4 by four means four wheel drive 4 by 2 means two wheel drive
I have read that the Sienna AWD system uses an open differential for the central differential (and I presume the front and rear as well) and relies on four wheel traction control to prevent wheel spin. It is always engaged.
The differential, often referred to as the "rear", is the gear housing which transmits the rotation of the driveshaft to the rear wheels. A four-wheel drive truck also has a differential for the front wheels.
To permanently disable, remove the drive shaft from the transfer case to the front differential.
