Most RWD cars built have the engine mounted in the front, but some rear-drive vehicles have them in the middle or rear of the car instead, a layout mostly seen in sports cars. One of the main advantages that front-wheel-drive cars have over RWD vehicles is their improved traction, which results from their weight distribution.
In front-wheel-drive cars, the engine's weight above the front tires allows the tires to grip the road more effectively. This extra traction makes front-drive cars more capable when it snows or when you need to navigate poorly paved roads. Since pulling is more effective than pushing when a vehicle has to dislodge itself from mud or snow, FWD vehicles are especially great for getting out of low-traction parking spots.
And that's before winter tires are installed. In addition to better traction, FWD cars typically have more room than vehicles with rear-wheel-drive. They lack a prominent driveshaft that runs from the engine in front to the wheels in the rear, which naturally creates a raised center console and large hump in the rear floor.
The engine can be positioned in some vehicles transversely to make the car's front end shorter, allowing more space for passengers and cargo with similar exterior dimensions.
Front-drive powertrains are also lighter than the transmission and axle assemblies in RWDs, so they get better gas mileage or can travel farther on one tank of fuel. Many economy cars are FWDs because they're more cost and space-efficient.
Although their traction is superior in bad weather, they don't take corners as precisely as rear-drive cars do. The pressure that both power and steering mechanisms put on the front axle tends to tax the front tires, creating a less dexterous feeling while driving. Sometimes, you might even feel the car is not responding to your steering very well or tends to delay your inputs. In rear-wheel drivetrains, power is transferred to the two back wheels.
There are many benefits to having power transferred to the rear wheels, including superior handling, acceleration, and braking. This setup transfers power to the front wheels, giving them the responsibility of moving and steering the vehicle. They are typically cheaper to manufacturer and are more space-saving than rear-wheel drive. While there are important differences between the two, both 4WD and AWD are drivetrain types that transfer power from the engine to all four wheels of your vehicle.
All-wheel drive is typically applied to drivetrains that include a differential between the front and rear drive shafts. We recommend 2WD for most drivers who drive in mild climates without a lot of snow. Whether or not you should buy a 2WD or 4WD vehicle depends entirely on your driving conditions and how you intend to use the vehicle.
Drivers who go off-roading or live in areas with a lot of snow may want to think about the added benefit of 4WD and how comfortable they feel driving in snow without the assistance of 4WD or AWD. For most drivers in most conditions, however, 2WD is all you need. Click here for more information on the advantages and disadvantages of four-wheel and all-wheel drive. Why Buy? Meet Our Staff.

Front Wheel Drive versus Rear Wheel Drive Since the Ford Model T and actually before most vehicles manufactured and sold in the United States were rear wheel drive RWD , that is the engine was typically in the front, the transmission right behind it, with a drive shaft running back to rear axle to drive the rear wheels.
Front wheel drive FWD , on the other hand, features the engine under the hood in combination with the transmission sometimes referred to as the transaxle that directly delivers power to the front wheels. Despite the impression many people have that the wave of front wheel drive started in earnest with the invasion of the Japanese brands, even those models sold in the US until the mids were predominantly rear-wheel drive.
Each system has its unique advantages. Front wheel drive makes for a very compact engine compartment, with minimal intrusion into the interior cabin of the vehicle no large hump for the driveshaft, now just a smaller hump to route exhaust, fuel lines, etc. Front wheel drive also has certain advantages when the roads get slippery or icy.
First, the bulk of the weight is over the front driving wheels which assists with traction. With a rear-wheel drive vehicle, the front tires might be initiating a turn but the rear wheels are still pointed straight ahead.
Excessive application of power at this point could cause a spin. RWD vehicles handle much better than front-wheel drive vehicles and you will notice the difference in curves, turns, and when navigating through traffic situations. Rear-wheel drive vehicles are better for towing because the front wheels have better steering without a ton of weight on them.
Plus, with the power transfer and the tongue weight of the trailer, the rear of vehicle squats, which gives the rear wheels more traction. If you get stuck, adding weight over the rear wheels may help.
