THE MOST POWERFUL Porsche Cayenne ever is now available. The twin-turbocharged engined Cayenne Turbo S has a 10 per cent power lift over the previous model, rising to a stunning 550bhp, with the torque boosted from a ‘meagre’ 700Nm to a far more acceptable 750Nm… Wow. This helps push the Cayenne’s performance to a 0-62mph in a sports car embarrassing 4.5 seconds and a potential top speed of 175mph. Why? Because you can. When you consider that the NEDC fuel consumption is 24.6mph it’s obviously a highly efficient engine, even if those lucky owners who can afford the £107,460 price tag are probably not that bothered. After all, who would buy a 550bhp 4×4 for its fuel economy? Exterior change include highlights to the air inlet grilles, headlight housings and mirrors, which are now, black matt. Inside there are new leather options and colours including Carrera Red and Black/Luxor Beige. Understandably for a prestige vehicle like this, it is fitted with the Porsche Vehicle Tracking System a very sophisticated system that has the approved Thatcham Category 5 standard. Buy a new Cayenne Turbo S and you also get a complimentary course at the Porsche Experience Centre, Silverstone.
