Thanks to its luxurious 300-centimeter (118.11-inch) wheelbase within an overall length of 5.09 meters (16.70 feet), the Audi Q7 has interior room to spare, and the interior flexibility is unrivalled. The seatbacks in the second row are divided into three fold-down sections to provide a level cargo floor. This increases the luggage space from a volume of 775 liters (27.37 cubic feet) to 2,035 liters (71.87 cubic feet). With the leather upholstery option, the middle seat now has an even more comfortable contour.
The Audi Q7 is available with six powerful and highly efficient direct injection engines, two of them gasoline-powered and four diesel engines, including the world’s most powerful diesel SUV, the Audi Q7 V12 TDI. Their power is transmitted via a convenient and fast-shifting six-speed tiptronic to the quattro permanent all-wheel drive, which distributes it between the axles with slightly more than half to the rear.
A novel technology from the Modular Efficiency Platform further improves fuel efficiency in all the engines: the recovery system, which during braking and coasting phases converts mechanical energy into electric energy and buffer-stores it in the battery. It reduces CO2 emissions by up to 5 g/km (8.05 g/mile).
The range of optional equipment is rounded off by technologies from the luxury class. The radar-supported adaptive cruise control regulates the speed and the distance to the preceding vehicle in a range from 30 to 200 km/h (18.64 to 124.27 mph) by acceleration and deceleration. If a threat is detected, the integrated Audi braking guard warns the driver at two levels.
From a speed of 60 km/h (37.28 mph), Audi lane assist helps the driver stay in lane by means of a camera that recognizes the lane lines. Audi side assist ensures safe lane changes above 30 km/h (18.64 mph) with the aid of a radar system that monitors the traffic pattern within 70 meters (229.66 feet) behind the vehicle. Finally, the Audi parking system advanced assists parking by means of a rearview camera and reference lines on the onboard monitor.
The world’s strongest diesel SUV: The Audi Q7 V12 TDI
Even when it was first rolled out, the Audi Q7 V12 TDI, the world’s strongest diesel SUV, had a uniquely distinctive look resulting from its large air intakes. The new version features modifications to the interior and the rear end.
The V12 diesel, with a 6-liter (6,000 cc) engine closely related to that of the R10 TDI racing car – a triple Le Mans winner – delivers 368 kW (500 bhp) and develops a torque of 1,000 Nm between 1,750 and 3,250 rpm.
Acceleration from zero to 100 km/h (62.14 mph) in 5.5 seconds and a capped top speed of 250 km/h (155.34 mph) equal the driving performance of a powerful sports car. Despite these impressive performance data, the V12 diesel gets by on an average of 11.3 liters of fuel per 100 km (20.82 US mpg). Its luxurious standard equipment includes 20-inch wheels, a Bose sound system, and many additional features.
