2011 Audi Q7 TDI Review

Audi Q7 Audi is the big sport for the individualist - the performance SUV sports, leisure, family and business associates. Now Audi has made it even more powerful and effective, with a choice of three new V6 engine and an 8-speed Tiptronic box.

Engines: a new series

Even more power, even greater efficiency: Audi has revised range of engines for the Q7. The two petrol engines, both V6 units, but with different powers, new, and is the second generation of the V6 TDI. A powerful V8 diesel engine completes the range. All engines in the Audi Q7 combines two technologies: forced induction and direct injection of fuel. A high-performance recovery recovers energy during braking is also standard with all engines of six and eight cylinders.

The new 3.0 TFSI petrol engine embodies the strategy of downsizing Audi to replace the volume of the engine supercharging. Within the 90-degree angle formed by the cylinder block is a motor-driven compressor that compresses the intake air. Two heat exchangers charge air cooler to avoid temperature increases, the engine uses more oxygen in the combustion process. Pile robust and spontaneous acceleration to make the 3.0 TFSI engine with its notes sound an ideal source of energy for the big performance SUV from Audi.

Two versions of Compressor V6 is available. The basic version develops 200 kW (272 hp) and maximum torque of 400 Nm (295.02 pounds feet) over a wide range of engine speed of 2250 rpm to 4750. It accelerates the Audi Q7 with 7.9 seconds from a standing start to 100 km / h (62.14 mph) and reaches a top speed of 222 km / h (137.94 mph) or 225 km / h (139 , 81 mph) with adaptive air suspension.

The stronger version of the 3 .0 TFSI delivers 245 kW (333 hp) and torque of 440 Nm (324.53 pounds ft) between 2900 and 5300 rpm. 100 km / h (62.14 mph) is reached in 6.9 seconds, with strong growth before continued until 243 km / h (150.99 mph) is reached, with the adaptive air suspension for the top speed is 245 km / h (152, 24 mph). Both versions of the 3.0 TFSI is remarkably efficient: fuel consumption in the EU test cycle, they are happy with 10.7 liters per 100 kilometers (21.98 mpg U.S.). Compared with previous engines, the 3.6 and 4.2 FSI FSI, fuel consumption is reduced by 1.4 and 2.0 l/100 km - 12 and 16 percent respectively.

The second generation of the 3.0 TDI, a new development that has virtually nothing in common with its predecessor - except a lot of power! It is rated at 176 kW (240 hp) and a constant 550 Nm (405.66 pounds ft) of torque all the way from 1750 to 2500 rpm. This V6 diesel Audi Q7 accelerates from zero to a typical main road speed 100 km / h (62.1 mph) in 7.9 seconds and reaches its top speed of 215 km / h (133.59 mph) or with air suspension adaptive, 218 km / h (135.46 mph). Its fuel consumption is remarkably low, averaging 7.4 liters per 100 km (31.79 mpg U.S.), the equivalent CO2 emissions of 195 grams per kilometer (313.82 g / mile). This is an improvement of 1.7 l/100 km or 19 percent.

The last 3.0 TDI engine weighs much less than before: 198 kg (436.52 pounds), a decrease of 20 kg (44.09 pounds). The new chain-driven timing and complexity of the cylinder wall is a process of internal friction. The new turbo is extremely sensitive, which was reflected in a rapid buildup of torque. Common rail system has been in recent years, further development: is the maximum pressure of 2000 bar, and can then be injected fuel spray pattern is very precise.

Carter heads the new 3.0 TDI with the cooling water circuits connected by separate valves. During the heating phase and when the load is not high, the coolant is not circulated in the engine block. It saves energy and increases the oil more quickly to its normal operating temperature. The new start-stop system shuts the engine when the Audi Q7 comes to a halt.

Audi also offers its customers a second version of the V6 TDI, 3.0 TDI Clean Diesel. It already meets the exhaust emission limits Euro 6 states that does not take effect until 2014, and the strict regulations of the United States. Sensors in the combustion chambers, a fuel injection pump common with an outlet pressure of 2,000 bar and a recirculation of exhaust gas to maintain high performance exhaust emissions to a minimum deal. DeNOx catalytic converter in the exhaust system reduces nitrogen oxides remaining through an addendum. The 3.0 TDI clean diesel is also developing 176 kW (240 hp) and has an impressive 550 Nm (405.66 lbs ft) of torque between 2,000 and 2,250 rpm. Take the Audi Q7 a stop to 100 km / h (62.14 mph) in 8.1 seconds and gives a top speed of 215 km / h (133.59 mph) or 218 km / h (135.46 mph) with adaptive air suspension . Its average consumption is 8.4 liters per 100 kilometers (28.00 U.S. mpg).

Audi Q7 4.2 TDI has also had its fuel consumption is reduced dramatically - by 9.9 (23.76 U.S. MPG) to 9.2 liters per 100 km (25.57 mpg U.S.) - by installing an injection system 2000 bars and minimize internal friction. But at the same time diesel V8, with its stable production of 250 kW (340 hp) delivers more torque than before. It now offers a powerful 800 nm (� 590.05 ft.) between the speeds of 1750 and 2750 rpm. The TDI engine gives great figures Audi Q7 performance worthy of a sports car. It accelerates from 0 to 100 km / h (62.14 mph) in 6.4 seconds and a top speed of 242 km / h (150.37 mph).

Transmission: Eight-speed is standard

Audi has given every six and eight cylinder versions of the Audi Q7 a new automatic transmission. The eight-speed tiptronic reduces fuel consumption by about five percent. It is based on the six-speed unit, but with an added friction clutch change. The ability to switch between eight relations keeps the engine is broken, the engine still running near its ideal operating point. All gear changes are the most rapid, flexible and very good immediately.

From 7.25 to 1, the overall prevalence of the eight-speed tiptronic relationship is unusually wide. In the lower ratios Audi Q7 accelerates, and a greater share of it rolls along efficiently at low speeds.

To further reduce fuel consumption, torque converter lockup clutch eliminates slip even at low revs. Any engine vibration that may occur as a result is suppressed by the new shock in the torque converter until almost all traces can be detected.

Drivers can choose between the S and programs - or make your own changes to the speed selector lever on the transmission or optional paddle changes. In combination with the 3.0 TDI in the new eight-speed tiptronic reached an exceptionally high level of efficiency. Its cooler oil is heated after a cold start by the hot coolant engine cooling system. Electric oil pump allows operation of the Audi Q7 start-stop system is possible, maintaining the oil pressure in the hydraulic system when the engine stops and closes the clutch to restart.

Eight-speed tiptronic transfer the engine power is quattro permanent four-wheel drive. In this way sport to share power, with 40 percent goes to the front and 60 percent of the rear wheels, but some on-and off-road situations, the difference between the mechanical center of action can address up to 65 percent of power in the face or up to 85 percent behind.

Body: the agile and safe

The Audi Q7 is one of those people in the house where they are. On the way out for its precise handling and sporty, and where the roof ends up showing surface features stunning terrain. Double wishbone suspension uses aluminum, combined with separate subplots. The wheel bearings are optimized to reduce friction. Management Servotronic varies the degree of power assistance according to vehicle speed.

The optional adaptive air suspension (standard on the Q7 4.2 TDI and Q7 V12 TDI) with electronic damping control suspension with variable height depending on the actual situation. On a highway at high speed reduces the body for better stability and low fuel consumption. Through rough terrain posed the body, pressing a button. Standard MMI terminal, the driver can choose from five modes: comfort, automatic, dynamic, off-road and lift. The adaptive air suspension is also available online dynamic S.

Audi Q7 18-inch wheels with 235/60 or 255/55 tires, depending on the engine chosen. But other wheels up to 21 inches in diameter can be chosen as an option. Braking is supported by large ventilated discs. With the two most powerful engines, even more hard carbon fiber reinforced ceramic lightweight material is available. Before them firmly if necessary by black calipers with the "Audi ceramic" letters. ESP stabilization program includes an off-road mode as standard, giving priority to the traction on loose surfaces. And when the driver encounters a steep downhill slope off-road, downhill to help is a useful support.
