Powered by a reworked version of the standard Cayenne Turbo’s twin-turbocharged 4.8-litre V8 petrol engine, the lightly restyled SUV possesses 20bhp and 31lb ft more than its already rapid predecessor.
It now packs 562bhp at 6000rpm and 589lb ft of torque on a band of revs between 2400 and 4000rpm – all channelled through an eight-speed automatic gearbox to each wheel via an electronically controlled multi-plate clutch four-wheel drive system.
Porsche says the increased reserves are sufficient to provide the new 2235kg Cayenne Turbo S with an official 0-62mph time of just 4.1sec and 176mph top speed – figures that better those of the model it replaces by some 0.4sec and a scant 1mph respectively.
Revealed alongside the 911 Targa GTS at the Detroit motor show, the facelifted Cayenne Turbo S establishes lofty new power and performance benchmarks within Porsche’s SUV line-up. It is claimed to be the first production SUV to lap the demanding Nurburgring circuit in less than eight minutes.
