Frankfurt Motor Show - When Porsche unveiled its third-generation Cayenne SUV on 29 August, it didn’t let all the cats out of the bag, holding something in reserve for the opening of the show, just a week later.
And that something was the Cayenne Turbo - the flagship of the new model line-up - although, truth to tell, Porsche is going to have to find a new name for its most potent pepper shaker, since every model in the Cayenne range is now turbocharged.
This one, however, has a four-litre biturbo V8, rated at 404kW and 770Nm, 22kW and 20Nm up on the previous Cayenne Turbo. That’s delivered to all four wheels via a new eight-speed Tiptronic S automatic transmission, with the help of active torque control, launching it to 100km/h in 4.1s (3.9 with the optional Sport Chrono package) and on to 286km/h flat out.
As is rapidly becoming the industry norm, the turbos are nestled in the V of the engine, making the distance from the combustion chambers to the turbo as short as possible, reducing turbo lag and making the engine more compact.
The Cayenne rolls on a new three-chamber air suspension system with active damping and, in true sports-car tradition, wider tyres (315/35) at the rear than in front (285/40), on special 21 inch Turbo rims.
The brakes have also been upgraded for the new Turbo with a layer of ultra-hard tungsten carbide on each steel disc,which not only increases braking performance and resistance to wear, says Porsche, but also reduces the amount of brake dust on the rims!
The Cayenne Turbo is also the first SUV with an adaptive roof spoiler, which flattens out when you’re running at high speed in a straight line, pops up to increase downforce on the rear axle when you hit the brakes and stays that way to improve cornering grip until you straighten up and hit the loud pedal again.
