2011 Audi Q7

For 2011, the Audi Q7 gets three new V6 engines and an 8-speed tiptronic transmission.

Continuing with its downsizing strategy, Audi will offer the Q7 with two versions of the 3.0 TFSI supercharged V6 engine. The first version of the engine makes 272-hp allowing the Q7 to hit 62 mph in 7.9 seconds. The second version of the 3.0 TFSI supercharged V6 is straight out of the Audi S4 making 333-hp allowing the Q7 to go from 0-62 mph in 6.9 seconds. The third V6 engine is the second-generation version of the 3.0 TDI, which now makes 240-hp and helps the Q7 return an impressive fuel-economy of 32 mpg.

The Audi Q7: new engines and eight-speed transmission for power and efficiency

The Q7 is the large Audi for the sporty individualist – the high-performance SUV for sport, leisure, family and business. Now Audi has made it even more powerful and efficient, with a choice of three new V6 engines and an 8-speed tiptronic transmission.

Engines: a new range

Even more power, even higher efficiency: Audi has revised the engine lineup for the Q7. The two gasoline engines, both V6 units but with different power outputs, are new, and so is the second-generation V6 TDI. A mighty V8 diesel completes the range. All the engines for the Q7 combine two technologies: forced induction and direct fuel injection. A high-performance recuperation system that recovers energy during braking is also a standard item with all six- and eight-cylinder engines.

The new 3.0 TFSI gasoline engine embodies Audi’s downsizing strategy: replacing engine displacement with supercharging. Within the 90-degree angle formed by its cylinder blocks there is an engine-driven supercharger that compresses the intake air. Two charge-air intercoolers prevent the air temperature from rising, so that the engine draws in more oxygen for the combustion process. Vigorous thrust and spontaneous throttle response make the 3.0 TFSI engine, with its sonorous note, an ideal source of power for the large high-performance SUV from Audi.

Audi has given all six- and eight-cylinder Q7 versions a new automatic transmission. The eight-speed tiptronic lowers fuel consumption by about five percent. It is based on the six-speed unit, but with another friction-clutch shift element added. Being able to shift between eight ratios keeps the jumps in engine speed low: the engine always runs close to its ideal operating point. All gear shifts are fast, flexible and take place extremely smoothly without delay.

At 7.25 to 1, the overall spread of ratios in the eight-speed tiptronic is unusually wide. In the lower ratios the Q7 accelerates powerfully; in the higher ratios it rolls along efficiently at low engine speeds.

To cut fuel consumption still further, the torque converter lockup clutch eliminates slip even at low engine speeds. Any engine vibration that could occur as a result is suppressed by the new damper in the torque converter until scarcely any trace can be detected.

Drivers can choose between the D and S programs – or make their own gear shifts at the transmission selector lever or the optional steering-wheel paddles. In combination with the 3.0 TDI the new eight-speed tiptronic achieves an exceptionally high level of efficiency. Its oil cooler is heated after a cold start by hot coolant from the engine’s cooling system. An electric oil pump makes operation of the Q7?s start-stop system possible: it maintains oil pressure in the hydraulic circuit when the engine stops, and closes the clutch for restarting.

The eight-speed tiptronic transmission transfers engine power to the quattro permanent all-wheel drive train. This splits the power in a sporty manner, with 40 percent going to the front and 60 percent to the rear wheels, but in certain on- or off-road situations, the mechanical-action center differential can direct up to 65 percent of the power to the front or up to 85 percent to the rear.

The design of the Q7 stands for power and presence; it is the visual expression of this large SUV’s character. Flowing surfaces create a moving sculpture, with the coup?-like roofline, the low window strip and the tautly curved panel surfaces being distinctive visual features. The outlines are sporty, strong and elegant.

The Audi Q7 is 5.09 meters (16.70 ft) long, 1.98 meters (6.50 ft) wide and 1.74 meters (5.71 ft) high. Its wheelbase of 3 meters (9.84 ft) creates a luxurious amount of space inside. The front-end styling is dominated by the large singleframe grille with chromed surround, and the headlamps. As an optional extra Audi can supply a xenon plus version with LED daytime driving lights and LED flashers, and also an adaptive light version with integrated turning and cornering lights as well as the low, full and highway beams.

Standard LEDs in the rear lights create a distinctive lighting pattern. The tailgate, which wraps around the rear roof posts in an S-shaped outline, and also the hood and the front fenders are made of aluminum. Audi supplies the add-on parts in a contrasting color as standard, or, if desired, in the same color as the body. The Audi Q7 always leaves the assembly line with a high-gloss package. Optional extras are the black styling package or the aluminum-look exterior package, which consists of an all-round chrome trim strip on the bumpers, door capping strips and door handles, and gives the Q7 even greater sophistication. The optionally available S line exterior package also adds further visual emphasis to this SUV’s sporty potential.
