The Audi Q7
The Audi Q7 The Audi Q7 is a full-size luxury crossover SUV of the German manufacturer Audi, unveiled in September 2005 at the Frankfurt Motor Show. Production of the Q7 began in autumn of 2005 at the Volkswagen Bratislava Plant in Bratislava, Slovakia.[6] It is the first SUV offering from Audi and went on sale in 2006. Later, Audi's second SUV, the Q5, was unveiled as a 2009 model. Audi has since unveiled a third SUV model, the Q3, which went on sale in the 3rd quarter of 2011. The Q7 shares its platform and chassis with the Volkswagen Touareg and the Porsche Cayenne.

Overview
The Q7 (internally designated Typ 4L) utilizes a modified version of the Volkswagen Group PL71 platform. Previewed by the Audi Pikes Peak quattro concept car, the Q7 is designed more for on-road use, and was not meant for serious off-road use where atransfer case is needed. In an off road test through the Australian outback it fared well for a "soft roader",[citation needed].[7] Although it lacks a low-range transfer case, it has quattro permanent four-wheel drive system with a central locking differential, and a self-levelling air suspension with Continuous Damping Control, called Adaptive air suspension, which helps in off roadsituations.

Q7 hybrid
The Q7 hybrid was a concept vehicle using the engine from the 4.2 FSI with an electric motor to provide 200 N�m (150 lb�ft) extra torque, and nickel-metal hydride battery. It has 0�100 km/h acceleration of 6.8s. The vehicle weighs 2,410 kg (5,310 lb), 140 kg (310 lb) heavier than the petrol counterpart. The vehicle was unveiled at the 2005 Frankfurt Motor Show. Audi reportedly was going to introduce a hybrid version of the Q7 sometime in the future. However, the low US dollar caused Audi to drop the plans for the US market, but stated limited quantities would be available for the commercial market.[19] Audi's research and development chief, Michael Dick, later announced Q7 hybrid would be produced in limited numbers for test purposes only and that development work would focus on a more advanced lithium-ion battery-based hybrid system for the Q5.

Q7 3.0 TDI clean diesel (2009)
The Q7 3.0 TDI clean diesel is a version of 3.0 V6 TDI with selective catalytic reduction. The engine was later used in the next generation of the Q7 for the European market.
