Transaxle - Four-wheel Drive

Four-wheel Drive

All Audi cars with longitudinal engines and their 'trademark' quattro four-wheel drive (4WD) system, along with their related marques from the Volkswagen Group which share the same layout, utilise a transaxle. This is mounted immediately behind the front-mounted engine (again, longitudinally) and contains the 'gearbox' (manual, automatic, DSG, or CVT), along with both the centre differential, and the front differential and final drive unit.

Other 4WD applications include:

• 1984–1986 Ford RS200 – mid-engined, with the gearbox in the front;
• 2007–on Nissan GT-R – front-engined, with the gearbox in the rear.
