Other full time all-wheel drive systems
Seen on: Audi Quattro, Mini All4, Land Rover/Range Rover
How they work: Vehicles that fall into this category are usually built from the ground up as all-wheel-drive vehicles. These all-wheel-drive systems are always engaged and differ from on-demand systems with a resting torque distribution that sits somewhere around a 50/50 split and the ability to send the majority of torque to either axle as needed. Rare cases, such as Mini Cooper Countryman's All4 system, are even able to send 100 percent of available torque to either the front or rear end.
Advantages: Increased grip in slippery situations, faster reaction to road conditions, increased safety, and best overall safety
