Self Study Program 429 – Audi Q5 – Engines and Transmissions 7-speed dual clutch gearbox 0B5 (S tronic)
VAG SSP 429. This Self-Study Programme describes the design, function and new features of the engines and gearboxes used in the new Audi Q5. With the introduction of the Audi Q5, Audi is extending its model range to include a compact SUV that sets new standards in its class. In addition to the Audi Q7 and the Audi A6 allroad quattro, Audi is now introducing a third model for the off-road segment.
The Audi Q5 will be manufactured at the Ingolstadt facility. It is a logical choice of location because the Audi Q5 is based on component parts which are used on the Audi A4 ‘08.
The new Audi Q5 combines the dynamism of a sports saloon with highly variable interior and versatile options for leisure-time and family use. Strong and efficient engines, Quattro permanent all-wheel drive and agile running gear have been brought together to create a superior technology package for both on and off road driving.
Highlights such as the innovative S tronic seven-speed dual-clutch gearbox and the driving dynamics system Audi drive select are the evidence that substantiates the Q5’s claim t o Vorsprung durch Technik. The sportiest SUV in its class, it is dynamic, multifunctional and comfortable.
