2011 Audi Q7 3.0 TDI
Audi has added a new and especially efficient member to its Q7 family. The Q7 3.0 TDI offers 150 kW (204 hp) while consuming an average of just 7.2 liters of diesel per 100 km (32.67 miles per U.S. gallon) – better than all direct competitors. At the same time, a 3.0 liter V6 drives this large SUV powerfully and smoothly. An eight-speed tiptronic and quattro permanent all-wheel drive round out the luxurious drivetrain.
Highly efficient – the new Audi Q7 3.0 TDI quattro with 150 kW
* fuel efficiency of just 7.2 liters of diesel per 100 km
* eight-speed tiptronic and quattro drive
The new V6 TDI in the Q7 is a high-tech engine. It weighs far less than 200 kilograms (440.92 lb) and extensive measures minimize internal friction. Innovative thermal management – a new feature of many Audi engines – is particularly complex in the 3.0 TDI. The crankcase and the cylinder heads have separate cooling water circuits; coolant is not circulated within the block while the engine is warming up.
A common-rail system with lightning-fast piezo injectors provides injection pressure up to 2,000 bar; the turbocharger and the camshafts' control times have been optimized for maximum efficiency. A start-stop system deactivates the engine as soon as the vehicle comes to a stop, and an energy recovery system – standard for the entire model line – stores energy during deceleration.
The EU 5 classification for this new entry model in the Q7 family will come as no surprise, just like its high fuel efficiency. On average, it needs 7.2 liters per 100 km (32.67 miles per U.S. gallon). And its CO2 equivalent is just 189 grams per km (304.17 grams per mile) – no other large SUV from a European brand boasts such a low value. The efficient TDI delivers 150 kW (204 hp). Its maximum torque becomes available just above the idling point: 450 Nm (331.90 lb-ft) remain constant between 1,250 and 2,750 rpm.
