The Audi Steppenwolf was a concept car produced by Audi and presented at the Paris Motor Show in 2001. The Steppenwolf was a study for a three-door compact crossover SUV based on the Volkswagen Group PQ34 platform used in the contemporary Audi A3 and Audi TT. Powered by a 3.2L V6 engine with four-wheel drive, the Steppenwolf had several novel features, including four-level adjustable air suspension (similar to the Audi allroad quattro), a removable carbon fibre hardtop or optional soft top, and an electro-hydraulic parking brake.
The Steppenwolf didn’t result directly in a production model. However, six years later, Audi presented the Audi Cross Coupé quattro, another concept car in the same class, and is planning a production version expected to be called the Audi Q3 for 2010.
