Audi's new A4 Allroad quattro has made its debut at the 2009 Geneva Motor Show. Click here for all the details.

Like Volvo's XC line of cars, the Audi Allroad is a tall wagon with AWD and off-road capability. To date, however, the Allroad has only been available in a version based around the A6.

These latest spy photos show a new A4-based Allroad in testing, confirming our news last year that such a model was in the works.

Cues that tip this car as a definite Allroad vehicle include the wider fenders and taller ride height, plus the new bumpers with a more ruggedized look, new air intake housings, addition of foglights and other off-road specific design cues.

As yet it's not clear if the A4 Allroad will be available as both a sedan and a wagon, but reports suggest the car will be kept simple - meaning air suspension appears to be an unlikely option. Previous spy shots showed an Allroad sedan prototype, and if built the car could be considered a sort of up-scale alternative to the many rally-bred AWD sedans currently on offer, such as the Subaru WRX and Mitsubishi Evo X.

Other new features the A4 Allroad could adopt include a dual-clutch transmission and a new 2.0L turbodiesel engine. Power levels would range from 143hp (106kW) and 236lb-ft (320Nm) of torque to 170hp (126kW) and 258lb-ft (350Nm) of torque. A range topper could also be launched with 204hp (179kW) and 295lb-ft (400Nm) of torque available. The remainder of the engines would be the same as all A4 models, and all Allroads by nature feature quattro AWD.

Expect the car to make its world debut as a 2010 model at the Frankfurt Motor Show in September.
