Thanking God is the best way to do if you have a car whose brand name was Audi. It’s such a big blessing to have a sumptuousness car as Audi. Lots of Audi are for sale in UK.
White as a stallion.
The key changes include the introduction of two versions of the supercharged 3.0-litre TFSI engine to replace the naturally aspirated 3.6-litre FSI and 4.2-litre FSI petrol units, the replacement of the 3.0-litre TDI unit with a considerably lighter and more fuel efficient successor and the integration of the new eight-speed tiptronic transmission first seen in the A8.
Already the star of the much praised Audi S4, and also familiar from the A6 and A6 all-road quattro, the new 3.0-litre TFSI petrol engine uses supercharging to compensate very effectively for its smaller capacity. 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.
The first of the two versions of the supercharged V6 replaces the 280PS 3.6-litre FSI, and offers 272PS and a 40Nm torque advantage with 400 Nm over a broad engine-speed range from 2,250 to 4,750 rpm. It powers the Q7 from a standing start to 62mph in 7.9 seconds, a 0.6-second improvement over its predecessor, and gives it a top speed of 140mph.
The more powerful version that takes over from the 4.2-litre FSI delivers 333PS and 440Nm of torque between 2,900 and 5,300 rpm, allowing the Q7 to reach 62mph from rest 0.5 seconds more quickly than the V8 at 6.9 seconds, and to continue to a top speed of 152mph.
No less impressively, both versions achieve a combined cycle fuel economy figure of 26.4mpg, an improvement of 12 per cent over the naturally aspirated V6 FSI and 16 per cent over the V8. With a shared CO2 output of 249g/km, both also benefit from major reductions of 40g/km and 55g/km compared with the models they replace.
Rear-end elegance.
The world’s cleanest diesel engine technology is of course also a feature of the latest Q7 range in the continuing Q7 3.0 TDI Clean Diesel, which not only already meets more stringent EU6 exhaust emission limits that are not due to come into force until 2014, but also tough US regulations. Special combustion chamber sensors and a DeNox catalytic converter in the exhaust system further reduce oxides of nitrogen by means of an additive. The 3.0 TDI clean diesels also develop 240PS and have an impressive 550 Nm torque output between 2,000 and 2,250 rpm. It takes the Q7 from a standstill to 62mph in 8.1 seconds, 0.4 seconds more quickly than before, and gives it a top speed of 135mph. Thanks to the new tiptronic transmission it works with, combined fuel economy works out at 33.6mpg, a six per cent improvement over the original version, resulting in an impressive drop in CO2 from 234g/km to 219g/km.
A new automatic transmission has also been instrumental in the achievement of considerably greater efficiency in the latest Q7. Based on the original six-speed tiptronic, but with another friction-clutch shift element added, the new eight-speed transmission improves fuel economy by around five per cent. Drivers can choose between ‘D’ and ‘S’ modes, or make their own gear shifts in ‘manual’ mode via the gear lever or the optional steering-wheel paddles. Shifts are quick, well judged and delivered with a smoothness that befits this luxury seven-seat SUV, and the wider spread of ratios made possible enables the engine to operate at lower revs in the higher gears, adding to the relaxed feel and helping to reduce fuel usage.
