Do you really know the difference between FF, RR, FR, 4WD and MR?

FF – Front Motor/Engine Front Drive

FF RC are fairly easy to control, but do not generally handle high speed very well. With more weight distribution forward, which makes them prone to understeer.

RR – Rear Motor/Engine Rear Drive

It increases the load on the rear driving wheels, giving them better grip of the road.

The disadvantage to a rear weight bias is that the RC can become unstable and tend to oversteer when decelerating.

FR – Front Motor/Engine Rear-wheel drive

During heavy acceleration, the front end rises, and more weight is placed on the rear wheels. Heavier weight at the back making the rear tires better to take simultaneous acceleration as it will have a better grip. The downside is that it is more difficult to handle on low grip surfaces as the RC is pushed rather than pulled.

4WD – All four wheels are drive wheels

Most 4WD layouts are front-motor/engine and are derivatives of earlier front-motor /engine, two-wheel-drive designs. Traction is nearly doubled compared to a two-wheel-drive layout. Given sufficient power, this results in unparalleled acceleration and drive ability on surfaces with less than ideal grip, and superior motor braking on loose surfaces. However, they normally cost more since 4WD require more machinery and complex transmission components.

MR – Midship Motor/Engine Rear Drive

The motor is located between the axles, and the rear wheels are the drive wheels. They are the least common configuration out of all. This design allows the RC to achieve ideal weight distribution, center of gravity and traction. When the RC’s weight is centered, the wheels won’t be thrown off balance by having to cope with extra weight, and the RC can be steered with more precision.
