We’ve tested the Audi Q7 3.0 TDI before, but this Clean Diesel version has been tweaked for better economy (31.7mpg on the combined cycle) and lower emissions (234g/km). The 2011 is cleaner still.
The Q7 makes a better tow car than the Lexus RX450h. The powerful engine sends 4.5 tonnes of car and caravan from 30-60mph in just 12.8 seconds, and the chassis is controlled and composed through the lane-change test even at 35mph.
The firm suspension keeps the outfit headed where the driver intends, but the ride is nothing like as comfortable as the Discovery’s.
The practicality judge liked the self-levelling suspension, the fitted Trailer Stability Programme, and a space-saver spare suitable for towing.
S Line models are well equipped, which partly justifies the £46,220 price. Expect to get back 43% of the original price after three years.
