Audi tremendously powerful V12 TDI engine in the Audi Q7. The six-litre engine delivers 5O0bhp of power, plus a maximum torque of 102kgm over an engine speed range between 1750rpm and 3000rpm. This engine, equipped with two turbochargers, takes the Audi Q7 from a standstill to 100kph in just 5.5 seconds. That makes this powerplant the crowning glory of a range of engines boasting impressive dynamism, power and efficiency. The Le Mans' race-bred Q7 V12 TDI already meets emission standard 5, which will probably come into force from the middle of 2010. The Bluetec technology, a new type of exhaust emission control, as well as controlled and cooled exhaust gas recirculation, the V12 TDI engine is both powerful and clean. At the heart of Bluetec technology lies an SCR (Selective Catalytic Reduction) catalytic converter.
