Why is fwd more efficient

Four-Wheel and All-Wheel Drivetrains 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. Since all the equipment is up front, they create more space and leg room in the back. Front-wheel drive has less components than any other drivetrain setup, making the vehicle lighter and improving its gasoline mileage.

There is greater tactile feedback through the steering wheel if the wheels are slipping. Front-wheel drive is a simpler system and tends to be less expensive to buy and maintain.

Front-Wheel Drive Cons Disadvantages : Since all the weight is located in the front of the vehicle, front-wheel drive cars tend to understeer. Front-wheel drive has worse acceleration than rear-wheel drive, which is why most sporty and race cars use rear-wheel drive. With all the weight up front, front-wheel drive can make handling more difficult. Front-wheel drive repairs and maintenance may cost more since they have to remove more parts for workable access.

Towing large loads is easier since the wheels doing the pulling are located closer to the load. Also, steering is much easier since the back wheels are providing the power while the front wheels do the work of steering. Rear-Wheel Drive Cons Disadvantages : Rear-wheel drive may be more fun to drive, but it also makes it more difficult to master. There is less interior space due to more room needed for the transmission tunnel and driveshaft. There may be less trunk room since more equipment must be placed underneath the trunk.

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. This problem is most noticeable when driving fast. Front-drive models wear out their tires quicker due to the weight of the engine on them, costing you more in repairs in the long term.

Having the front wheels handle all of the power and most braking also puts more strain on some steering and suspension components. Also, the nose-heavy layout of FWDs sometimes makes them succumb to torque steer or understeer, a condition in which rapid acceleration causes the vehicle to drift left or right on its own.

As a result, most high-performance sports cars choose rear-wheel-drive or all-wheel-drive layouts. Fortunately, electronic traction control in many modern FWDs helps to mitigate torque steer and related problems. Front-wheel-drive cars can also have relatively large turning circles, as transversely mounted engines allow less space for the front wheels to turn. That makes large FWD sometimes challenging to make U-turns.

For most of the automobile's history, rear-wheel-drive was the default configuration for vehicles. The main advantage of the rear-wheel layout is that each set of tires has just one task, ensuring an equal amount of stress on both: The front set steers, while the rears handle the power. Rear-wheel-drive cars can manage turns more smoothly as a result because the drive wheels aren't overtasked.

The balanced feel of RWDs is why performance cars use the system. Rear-wheel-drive cars sometimes have more towing capacity than FWDs because the weight of the trailers gives the rear tires of the RWD more traction.

Plus, the RWD's front tires, being less burdened than an FWD, can usually more accurately maneuver the trailer through traffic. Rear-wheel-drive vehicle platforms have more flexible designs, as the engine can sit in the front, middle, or back of the car, whereas front-wheel-drive vehicles require the engine to sit at the front.

Our opinion, if you are in the need for speed and you need a vehicle that can put up with some wear and tear then RWD is probably for you.
