In a second release today the German automaker is announcing that a choice of three new V6 engines plus an 8-speed tiptronic transmission are now available for the 2011 Audi Q7 on the company's home market.

Two of these V6 units will use gasoline and have different power levels while the third is a V6 TDI. All three engines combine forced induction and direct fuel injection plus the 2011 AUdi Q7 now comes with a high-performance system that recovers energy duringbraking as standard. 

The first new engine is the 3.0-litre TFSI that produces 272 HP and 400 Nm of toruqe, thanks to which the 2011 Audi Q7 sprints from 0 to 100 Km/h in 7.9 seconds and returns 22 mpg (10.7-litres per 100 Km).

The second version 2011 Audi Q7 3.0 TFSI has the same fuel consumption figures while outputing 333 HP and 440 Nm of torque, and accelerating to 100 Km/h from a standstill takes 6.9 seconds.

Finally the 2011 Audi Q7 3.0 TDI boosts 240 HP and 550 Nm of torque, that are enough to accelerate the German SUV to 100 Km/h from a standstill in 7.9 seconds and hit a top speed of 215 Km/h. Fuel consumption figures for the turbo diesel V6 version indicate that there are 7.4-litres needed to cover 100 Km (31.8 mpg).

Audi press release :

The Q7 is the large Audi for the sportyindividualist – the high-performance SUV for sport, leisure, family

andbusiness. Now Audi has made it even more powerful and efficient, with achoice of three new V6 engines and an 8-speed tiptronic transmission.

Engines: a new range
Evenmore power, even higher efficiency: Audi has revised the engine lineupfor the Q7. The two gasoline engines, both V6 units but with differentpower outputs, are new, and so is the second-generation V6 TDI. Amighty V8 diesel completes the range. All the engines for the Q7combine two technologies: forced induction and direct fuel injection. Ahigh-performance recuperation system that recovers energy duringbraking is also a standard item with all six- and eight-cylinderengines.

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

Two versions of the superchargedV6 are available. The basic version develops 200 kW (272 hp) and has amaximum torque of 400 Nm (295.02 lb-ft) over a broad engine-speed rangefrom 2,250 to 4,750 rpm. It accelerates the Q7 in 7.9 seconds from astanding start to 100 km/h (62.14 mph) and gives it a top speed of 222km/h (137.94 mph), or 225 km/h (139.81 mph) with adaptive airsuspension.

The more powerful version of the 3.0 TFSI delivers245 kW (333 hp) and a torque of 440 Nm (324.53 lb-ft) between 2,900 and5,300 rpm. 100 km/h (62.14 mph) are reached in 6.9 seconds, withpowerful forward progress continuing until 243 km/h (150.99 mph) arereached; with adaptive air suspension the top speed is 245 km/h (152.24mph). Both versions of the 3.0 TFSI are impressively efficient: in theEU fuel consumption test cycle they are content with 10.7 liters per100 kilometers (21.98 US mpg). Compared with the previous engines, the3.6 FSI and the 4.2 FSI, fuel consumption has been reduced by 1.4 and2.0 l/100 km – 12 and 16 percent respectively.

Thesecond-generation 3.0 TDI, a new development, has effectively nothingin common with its predecessor – apart from plenty of power! It has arated output of 176 kW (240 hp) and a constant 550 Nm (405.66 lb-ft) oftorque all the way from 1,750 to 2,500 rpm. This V6 diesel acceleratesthe Q7 from a standstill to a typical main-road speed of 100 km/h (62.1mph) in 7.9 seconds and reaches its top speed at 215 km/h (133.59 mph)or, with adaptive air suspension, 218 km/h (135.46 mph). Its fuelconsumption is impressively low, averaging 7.4 liters per 100 km (31.79US mpg), which is equivalent to CO2 emissions of 195 grams perkilometer (313.82 g/mile). This is an improvement of 1.7 l/100 km or 19percent.

The latest 3.0 TDI engine weighs much less than before:198 kilograms (436.52 lb), a reduction of 20 kg (44.09 lb). A newchain-driven timing gear and a complex cylinder wall machining processhave reduced internal friction. The new turbocharger is exceptionallyresponsive, making itself felt as rapid torque buildup. The common railinjection system has also undergone further development: it has amaximum operating pressure of 2,000 bar and can therefore inject fuelin an extremely precise spray pattern.

The crankcase and cylinderheads of the new 3.0 TDI have separate cooling water circuits connectedtogether by valves. During the warm-up phase and when loads are nothigh, the coolant is not circulated in the engine block. This savesenergy and raises the oil more quickly to its regular operatingtemperature. The new start-stop system switches off the engine when theQ7 comes to a standstill.

Audi also offers its customers a secondversion of the V6 TDI: the 3.0 TDI clean diesel. It already meets theexhaust emission limits laid down in the Euro 6 standard, which doesnot come into force until 2014, and the tough US regulations as well.Sensors in the combustion chambers, a common-rail fuel injection systemwith a delivery pressure of up to 2,000 bar and a high-performanceexhaust gas recirculation system keep untreated exhaust emissions to aminimum. A DeNox catalytic converter in the exhaust system reduces theremaining oxides of nitrogen by means of an additive. The 3.0 TDI cleandiesel also develops 176 kW (240 hp) and has an impressive 550 Nm(405.66 lb-ft) of torque between 2,000 and 2,250 rpm. It takes the Q7from a standstill up to 100 km/h (62.14 mph) in 8.1 seconds and givesit a top speed of 215 km/h (133.59 mph), or 218 km/h (135.46 mph) withadaptive air suspension. Its average fuel consumption is 8.4 liters per100 km (28.00 US mpg).

The Q7 4.2 TDI has also had its fuelconsumption drastically reduced – from 9.9 (23.76 US mpg) to 9.2 litersper 100 km (25.57 US mpg) – by installing a 2,000-bar fuel injectionsystem and minimizing internal friction. Yet at the same time the V8diesel, with its unchanged power output of 250 kW (340 hp), deliversmore torque than before. It now supplies a vigorous 800 Nm (590.05lb-ft) between engine speeds of 1,750 and 2,750 rpm. The big TDI enginegives the Q7 performance figures worthy of a sports car. It acceleratesfrom 0 to 100 km/h (62.14 mph) in 6.4 seconds and has a top speed of242 km/h (150.37 mph).

Power transmission: eight speeds are standard
Audihas given all six- and eight-cylinder Q7 versions a new automatictransmission. The eight-speed tiptronic lowers fuel consumption byabout five percent. It is based on the six-speed unit, but with anotherfriction-clutch shift element added. Being able to shift between eightratios keeps the jumps in engine speed low: the engine always runsclose to its ideal operating point. All gear shifts are fast, flexibleand take place extremely smoothly without delay.

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

To cutfuel consumption still further, the torque converter lockup clutcheliminates slip even at low engine speeds. Any engine vibration thatcould occur as a result is suppressed by the new damper in the torqueconverter until scarcely any trace can be detected.

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

Theeight-speed tiptronic transmission transfers engine power to thequattro permanent all-wheel drive train. This splits the power in asporty manner, with 40 percent going to the front and 60 percent to therear wheels, but in certain on- or off-road situations, themechanical-action center differential can direct up to 65 percent ofthe power to the front or up to 85 percent to the rear.

The chassis: agile and safe
TheQ7 is one of those personalities who are at home wherever they may be.On the road it excels with its precise, sporty handling, and where thehardtop surface ends it demonstrates impressive offroadcharacteristics. The suspension uses double wishbones made of aluminum,attached to separate subframes. The wheel bearings have been optimizedto reduce friction. The servotronic steering varies the degree of powerassistance according to the vehicle’s speed.

The optionaladaptive air suspension (standard on the Q7 4.2 TDI and Q7 V12 TDI)with electronic shock absorber control varies the ride height to suitthe actual situation. On a high-speed road it lowers the body forenhanced stability and lower fuel consumption. Across rough terrain itraises the body if a button is pressed. At the standard MMI terminalthe driver can choose between five operating modes: comfort, automatic,dynamic, offroad and lift. The adaptive air suspension is alsoavailable as a dynamic S line version.

The Audi Q7 has 18-inchwheels with 235/60 or 255/55 tires, depending on the chosen engine. Butother wheels up to 21 inches in diameter can be selected as optionalextras. Braking is looked after by large ventilated disks. With the twomost powerful engines even larger disks made from lightweightcarbon-fiber reinforced ceramic material are available. They aregripped firmly when the need arises by black callipers with “Audiceramic” lettering. The ESP stabilization program includes an off-roadmode as standard that gives priority to traction on a loose surface.And when the driver encounters a steep downhill slope off-road, thehill descent assist is a useful aid.

Design and body: sculpture in motion
Thedesign of the Q7 stands for power and presence; it is the visualexpression of this large SUV’s character. Flowing surfaces create amoving sculpture, with the coupé-like roofline, the low window stripand the tautly curved panel surfaces being distinctive visual features.The outlines are sporty, strong and elegant.

The Audi Q7 is 5.09meters (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 luxuriousamount of space inside. The front-end styling is dominated by the largesingleframe grille with chromed surround, and the headlamps. As anoptional extra Audi can supply a xenon plus version with LED daytimedriving lights and LED flashers, and also an adaptive light versionwith integrated turning and cornering lights as well as the low, fulland highway beams.

Standard LEDs in the rear lights create adistinctive lighting pattern. The tailgate, which wraps around the rearroof posts in an S-shaped outline, and also the hood and the frontfenders are made of aluminum. Audi supplies the add-on parts in acontrasting color as standard, or, if desired, in the same color as thebody. The Audi Q7 always leaves the assembly line with a high-glosspackage. Optional extras are the black styling package or thealuminum-look exterior package, which consists of an all-round chrometrim strip on the bumpers, door capping strips and door handles, andgives the Q7 even greater sophistication. The optionally available Sline exterior package also adds further visual emphasis to this SUV’ssporty potential.

The interior: abundant space
TheQ7 sets standards for flexibility: no fewer than 27 seat configurationsare possible. Depending on the wishes of the customer, Audi can supplyits large SUV as a five-, six- or seven-seat version. This last versionhas comfortable single rear seats and a third row of seats at the backfor occupants up to 1.60 meters (5.25 ft ) tall. As a standard feature,the seat backs in the second row can be folded down to provide a levelcargo floor. This increases load capacity from 775 liters (27.37 cubicft) to 2,035 liters (71.87 cubic ft) in volume.

Operation ofthe controls is simple and logical, and the clearly marked instrumentsare easy to read. For the driver and front passenger there is a choiceof three seat versions: standard seats, electrically adjustable sportseats and climatized luxury seats that can be both heated andventilated. The elegant lines of the interior, with many restraineddetails, communicate the typical feeling of wellbeing that the Audidriver or passenger enjoys. The ambient lighting provides subtlehighlights, and many of the control elements have fine chrome trim. Theworkmanship is typical of Audi – quality with no compromises.

Thechoice of colors and materials emphasizes the distinguished characterof the interior of the Q7. A variety of leather grades, headlinings andinlays are available, and for the individualist there are leather anddesign packages of various styles. The S line sports package uses coolblack throughout the interior, with subtle accents in the trim andupholstery. Among the items it includes are sports suspension and20-inch wheels.

Equipment and trim: the highest standards of luxury
TheAudi Q7 comes with an opulent array of standard equipment features,including two-zone deluxe automatic air conditioning, high-beamassistant, an MMI radio operating system complete with audio system andeight speakers, a double load floor in the cargo area with storagecompartment and a dirt tray. Roof rails are also fitted.

Astandard item when the optional driver information system is chosen isthe on-board computer with efficiency program. This monitors thevehicle’s energy flows and displays the requirements of the mostimportant consumers, with hints on how to reduce consumption.

Thelist of optional extras includes such luxury features as theconvenience key, four-zone automatic air conditioning, a dark glasspanoramic roof and a cool box. Items of interest for sport and leisureinclude an electric tailgate mechanism, baggage retaining rails and asliding storage box. In the program of accessories are such items as apivot-head tow hitch – the large SUV can tow a trailer weighing up to3.5 metric tons (7,716 lb).

In the infotainment area Audi alsooffers a complete modular system. The top-of-the-line version has anintegral hard disk drive for navigation, music, and telephone data, acolor monitor with 3D graphics, a DVD player, and voice control. It canbe expanded into a luxury media center with features such as aBluetooth telephone, TV tuner, digital radio tuner, plus rear seatentertainment. A special highlight is the Advanced Sound System fromBang & Olufsen with its 14 channels, 1,000 watts of power and 14speakers. In the cockpit area two acoustic lenses reproduce the treblefrequencies; when the system is started, they extend out of the dashpanel.

The range of optional equipment is rounded off by advanceddriver assistance systems. The adaptive cruise control system regulatesspeed and following distance by means of targeted accelerating anddecelerating. If a risk is detected, the integral Audi braking guardprovides a warning. Audi lane assist helps the driver to stay in lane;Audi side assist employs radar to help drivers change lanes moresafely. The Audi parking system advanced assists parking by means of arearview camera.
