Now we're not expecting the SQ7 to be welcomed with open arms on PistonHeads. The prospect of a large, fast diesel Audi SUV won't appeal to many enthusiasts, after all. However, it's capable of 0-62mph in 4.8 seconds and speed does matter, so here's what you need to know about the latest addition to the fast Audi range.
Yes, it really has happened
'Electric powered compressor' (EPC) is the big news under the big bonnet of this Q7, the technology said to be a world first. It builds on the electric turbo technology seen in the
RS5 TDI concept
and, credit where credit is due, it sounds very clever. Essentially it provides boost without exhaust gas; the EPC is located between the intercooler and engine and is said to deliver "the dynamic delivery of power in less than 250 milliseconds". The compressor is driven by a 48-volt electrical subsystem and spins at up to 70,000rpm. Perhaps most excitingly, Audi boasts that "turbo lag is history." Not lacking confidence then...
With that compressor and two turbos on the 4.0-litre V8 diesel, power is rated at 435hp and torque at a gargantuan 664lb ft. From 1,000rpm. So that's twice the torque of an M135i from basically idle... Should be swift enough for most then! Officially the SQ7 TDI is capable of 0-62mph in 4.8 seconds before charging into a 155mph limiter. What would it do unrestricted? The transmission is an eight-speed auto, the fuel consumption is 38.2mpg by the NEDC test and the CO2 is 194g/km.
Elsewhere it's the usual array of Audi configurable chassis technology and features to make a two-tonne diesel 4x4 feel as dynamic as possible. There's adaptive air suspension with "S-specific tuning" as standard, but why make do with that when you could have "networked suspension control"? An optional dynamic package brings together a sport diff, electromechanical roll stabilisation and all-wheel steering. Then a suspension control unit manages the diff, the dampers, the air springs and the roll force distribution, apparently ensuring optimal networking and coordination of those functions. And the result for the driver? "Outstanding handling in any situation."
Probably the only view you'll get with 664lb ft
The SQ7's roll stabilisation is new for the Q7, and this is the first time the sport diff has been seen in Audi's largest SUV too. Need another quote? "Even if the rear end starts to swing out, the Quattro sport differential brings it back under control." Plus, if you're really planning to push the SQ7, best spec the optional carbon ceramic brakes.
Inside and out this is familiar Audi S fare, the five-metre body adorned with a new grille, aluminium mirrors and four exhausts. The headlights are standard LEDs, though the optional Matrix LED lights will be just the thing if your closing speed doesn't get the message across. All while enveloped in a "sporty and elegant" cabin with up to six passengers.
The SQ7 TDI will be available to order from the spring; UK prices haven't yet been confirmed but in Germany it will cost 89,900 euros, or £69,500 at today's exchange rate. So if the Porsche Cayenne Diesel S simply isn't powerful enough, you know what to do!
