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 7.2 liters of diesel per 100 km (32.67 miles per U.S. gallon)
An eight-speed tiptronic and quattro permanent all-wheel drive round out the drivetrain.
The new engine 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..
This large SUV accelerates from 0 to 100 km/h (62.14 mph) in 9.1 seconds. In the version with an optional air suspension, it reaches a top speed of 205 km/h (127.38 mph); with steel suspension, 202 km/h (125.52 mph).
