Front-engine, four-wheel-drive layout

This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road driving.

In terms of racing purposes, whether it be on-road or off-road, can be described as follows, A team that pursues the Weak LS4WD architecture will minimize the development cost of the front-wheel drive system at the expense of having a larger rear powertrain.

This layout is designed for off-road vehicles to have the most traction in strenuous situations without losing too much cargo space at the same time.

For normal road driving, these vehicles are shifted into 2WD mode, to prevent damage to the transfer case.

A vehicle has four-wheel drive when the front and rear driveshafts can be locked together to move at the same speed and send the same amount of torque to all four wheels.
