PORSCHE has wound up the Cayenne SUV's wick even further, with news that the German sports car maker will offer an even more powerful version of its hyper-SUV here by mid-2006.
The Cayenne Turbo S produces 383kW of power at 5500rpm and 720Nm of torque from just 2750rpm – an increase of 52kW and 100Nm over the current Cayenne Turbo flagship.
The enhanced biturbo 4.5-litre V8 engine is now second only to the Carrera GT as the most powerful production model Porsche ever built.
The more muscular engine delivers a zero to 100km/h sprint time of just 5.2 seconds and top speed of 270km/h, all from a vehicle tipping the scales at more than 2.3 tonnes.
The performance improvements have been gained through upgraded and more efficient intercoolers, increasing turbo boost pressure by 0.2 bar (to a maximum of 1.9 bar) and a modified engine management system.
The S also gets bigger brakes, 380mm up front (up 30mm over the Turbo) and 358mm out back (up 28mm).
Exterior styling cues remain largely unchanged with 20-inch SportTechno wheels, quad exhausts, Turbo S badging inside and out, and a new Navy Blue Metallic exterior colour.
The special 275/40 tyres on the Cayenne Turbo S are rated for speeds up to 300km/h.
The Cayenne Turbo S goes on sale mid-year and will be sold in limited numbers.
