Audi Q7

Given the firm's reputation for all-wheel-drive technology, the move seems only natural - but is the Q7 good enough to establish itself as king of the hill? We were first behind the wheel of a 3.6-litre V6 example to find out.

On initial impressions, the Q7 certainly looks imposing, and our generously equipped, seven-seat test car was luxurious inside. It's not quite as stylish or sumptuous as the big A8, but it's spacious.

The versatile, fold-flat seating is easy to use, and the driver has a commanding view of the road ahead. An enormous three-section glass sunroof lets light flood in. At idle, the V6 engine is impressively refined, while throttle res-ponse is good and performance easily a match for V8 rivals. Fuel economy is around 25mpg, yet we suspect the figure would soon dip if you drive the car hard.

Steering is accurate and the Q7 resists roll through corners, but the air-suspension is very firm. Still, build quality is first class so, despite the fidgety ride, there are no squeaks in the leather-clad cabin.

While the Audi's ability is clear, it's difficult to see exactly what it adds to the class. The Q7 is certainly sporty, but Porsche's Cayenne is better to drive. And although it's spacious, the Land Rover Discovery is much more practical.

However, with a strong image, unique looks and expected good residuals, the newcomer is guaranteed to make a splash when it arrives in UK showrooms in July.
