Audi's box-fresh Q7 SUV isn't due to officially launch here until Friday, but already word is getting out that a hopped-up SQ7 variant is on its way with a muscle-bound 320kW 4.0 litre turbodiesel V8 powerplant under the bonnet..
According to Dutch website autoblog.nl, a leaked spec sheet details an upcoming "4.0 TDI V8 320kW quattro tiptronic". Right now the most powerful Q7 model available is the Q7 e-tron (below), which boasts 275kW and 700Nm from a diesel-electric hybrid setup.
The SQ7's turbodiesel 4.0 could be closely related to the 4.2 litre bent-eight used by the Porsche Cayenne S Diesel, which makes 283kW and 850Nm with the aid of a pair of turbochargers.
It's unclear what tricks Audi will employ to wind the smaller 4.0 V8 to 320kW (and lord knows how much torque), but the SQ7 is rumoured to be the first recipient of Audi's electrically-assisted turbo technology.
It will also be the second S-badged Audi to feature a diesel-drinking engine.
The SQ5 has been selling strongly in Australia since its introduction in 2013 thanks to its combination of power, space and frugality, so it's no surprise to see Audi planning a similar performance option for the new Q7 range.
As for when it will launch, expect to see the SQ7 make its official debut at the Frankfurt Motor Show in September.
