Porsche Cayenne S diesel

Porsche has added a second, higher-performance diesel model to its Cayenne range.

The Porsche Cayenne S diesel is powered by a 4.2-litre twin-turbo V8 diesel and sits above the standard Cayenne Diesel, which is powered by a 3.0-litre V6. Power is 378bhp versus the V6’s 242bhp.

The Cayenne S Diesel can sprint from 0-62mph in 5.7 seconds, two seconds quicker than the V6 diesel. Top speed is 157mph.

Despite the high performance, the Cayenne S diesel is still tuned for efficiency. It has a stop-start system, which Porsche claims is a world-first for a V8-powered diesel SUV. This helps return a claimed 34mpg, while the car emits 218g/km of CO2. That fuel consumption helps the Cayenne S diesel manage an impressive range of 745 miles from its 100-litre fuel tank.

To distinguish the Cayenne S diesel from the lower-powered diesel model, the new car has a Cayenne S badge at the back and ‘diesel’ badges on the front wings. It’s also got larger brakes and silver brake callipers – a trademark feature of all V8-powered Cayennes.

The Cayenne S Diesel arrives in UK showrooms in January, with prices starting from £58,243.
