Audi has revealed a stonkingly-quick version of its Q7 SUV in a bid to take on the Porsche Cayenne Turbo and Range Rover Sport – while offering diesel levels of economy.
Launched in the wake of the Geneva Motor Show (no, we don’t know why either), the SQ7 boasts the most powerful diesel fitted to any SUV on the market with a twin-turbo 4.0-litre V8 TDI producing 435hp and 664lb-ft of torque. This means that 0-60mph is dispatched in 4.8 seconds – only a tenth slower than the 542hp petrol powered Range Rover Sport SVR.
One of the reasons for this SVR bothering pace, is a 48volt electric powered compressor, mounted beneath the luggage compartment, which seeks to consign turbo lag to the pages of history.
The compressor uses electrical power rather than exhaust gases to power up the engine when starting off and accelerating from high gears, enabling a torquey delivery and a dynamic response from across the speed range, with no turbo lag to spoil things.
Yet despite the impressive performance, Audi claims this engine has the consumption figures of a six-cylinder engine. It returns a combined 38.2mpg and produces 194g/km CO2.
It also features an enlarged 85-litre fuel tank meaning it should be good for a range of more than 700 miles.
Other modifications include a revised eight-speed tiptronic gearbox to improve efficiency, a self-locking centre differential and lightweight aluminium suspension. Carbon ceramic brakes are available as an option. Other options are sportier seats, ambient lighting and Audi’s virtual cockpit.
The Audi SQ7 is set to be released in spring and will cost around £70,000.
