HALDEX
Haldex Traction is a product of Swedish company HaldexAB, now owned by BorgWarner, that has specialised in manufacturing all-wheel drive systems derived from front-wheel drive setups for many years now. Haldex 4WD typically takes a front-wheel drive platform, such as the VW Golf, Audi A3, or Mercedes-Benz A Class, and converts the FWD system into all-wheel drive, normally through the use of electronic sensors and differentials to redirect power to the rear wheels.
