2011 Audi Q7: New engines and a new transmission
Audi is enjoying success after success in practically all markets. The quality of its vehicles is part of the equation, but the fact that this manufacturer is constantly updating and improving its models is another important factor. We saw the proof once again this year with the 2011 Q7, which featured its fair share of improvements. For 2011, Audi reshuffled the Q7’s line-up of engines, offering two new gas-powered V6s and a second-generation TDI V6. All are supercharged and get direct fuel injection, while an optimized kinetic energy recuperation system also comes factory-standard.
The 3.0 TFSI, the new gas engine, replaces the 3.6-L naturally-aspirated V6 that produced 225 hp. Resting at 90 degrees between the cylinder banks is a compressor activated by the engine. Two supercharged air coolers ensure that the temperature remains constant. This gives more oxygen to the cylinders for more effective combustion. It delivers 272 HP, which is 47 more than the naturally-aspirated V6 (which had more cylinders). Torque has also gone up from 266 lbs-ft to 295 lbs-ft. Not bad at all for an engine that consumes less fuel than its predecessor. With this engine, the Q7 can do 0-100 km/hr in 7.9 seconds and reach a maximum speed of 222 km/hr.
Worried that there’s no V8? Relax! Audi has found a way to put your mind at ease… The 4.2-L V8 has been replaced by a more powerful version of the 3.0-L V6 TFSI. It pumps out 333 hp and 325 lbs-ft of torque. Sure, you lose 33 horses, but the torque level is exactly the same as the V8’s. But, most importantly, this engine’s performances are even better! It does 0-100 km/hr in just 6.9 seconds (one second less than the 4.2-L V8) and reaches a maximum speed of 243 km/hr. And the icing on the cake is that the average fuel consumption of both these V6s has dropped by 12% and 16% respectively.
Let’s not forget that a new diesel engine is also available. This second-generation 3.0 TDI is a complete departure from the model it is replacing. It delivers 240 horses – 15 more than before – while its torque level is unchanged at 405 lbs-ft. The diesel engine will take the Q7 from 0-100 km/hr in 7.9 seconds and bring it to a maximum of 215 km/hr. But it’s real appeal lies in its fuel consumption, which averages at 7.4 litres/100 km. That’s down 19% compared to the previous engine.
Eight-speed transmission!
Audi is equipping its Q7s with a new automatic gearbox: a Tiptronic eight-speed. This transmission helps reduce fuel consumption by about 5%. Based on the six-speed transmission, it features an additional gear-change element. With eight speeds, there are no jolts as you shift gears and the engine continually runs at or near its ideal operating point. Gear shifts are spontaneous, quick and flexible.
The driver can choose either the D or S driving programs, or shift by using the lever or the optional paddles on the steering wheel. Interacting with the 3.0 TDI, the new Tiptronic eight-speed offers some great performances. On cold starts, its oil cooler is heated with hot coolant from the engine circuit. An electric oil pump ensures that the stop-start function works properly: when the engine stops, it maintains oil pressure in the hydraulic system, and when it starts, it closes the clutch.
The eight-speed Tiptronic transmission transfers engine power to the quattro permanent AWD, splitting the power 40/60 between the front and back, respectively. But in more difficult road or terrain conditions, the mechanical-action center differential can direct up to 65%of the power to the front or up to 85% to the rear. The suspension is supported by the aluminum double wishbone, attached to separate subframes. As for the Servotronic steering, it varies the degree of power assistance according to the vehicle’s speed. Adaptive air suspension with electronic shock absorption is available on option. It adjusts ground clearance according to the situation. Simply press a button to raise the vehicle on rough terrain. Thanks to the standard MMI control system, the driver has a choice of five operating modes: Comfort, Automatic, Dynamic, Offroad and Lift.
Always refined
The biggest changes for 2011 are under the hood. The vehicle body remains the same, as does the sophisticated interior. According to Audi, no less than 27 seat configurations are possible. In back, you get comfortable individual seats, as well as a third row of seats (for passengers 5’5" and under only). Seat backs can be folded down for a completely flat floor, bringing the cargo space up from 775 to 2,035 litres. Audi has made a solid name for itself for its dashboards, and the Q7 does nothing to tarnish its rep. The instrumentation layout is so good, you can see everything you need to see at first glace. Interior lighting adds a nice touch and several of the controls flash a little chrome. The quality of the fit and trim is also up to Audi standards. And as you’d expect from a vehicle in this price range, there are numerous electronic driver assist systems.
Worth mentioning is the adaptive cruise control system that automatically adjusts your following distance by accelerating or decelerating. Lane Assist will help keep drivers on the right trajectory, while Side Assist uses a radar to help you change lanes more safely. Finally, the Advanced Parking System features a back-up camera to help you with your parking manoeuvres.
So many choices…
Whatever model or engine you choose, it’s hard to go wrong with an Audi Q7. Its physique is original and stands out against the other SUVs in its category. What’s more, the interior is remarkably comfortable and practical. If the engine selection has you wondering what to do, go for the diesel, you won’t regret it. If only gas stations would offer more user-friendly diesel pumps…
On the highway, the Q7’s accelerations and pick-up are irreproachable, as the new eight-speed transmission delivers on its promise. Its road handling is almost sporty if you’ve got the right options. And even the simplest version of the Q7 will impress you with its handling and driving pleasure. It’s vehicles like this that will have you buying lottery tickets.
