Porsche Panamera diesel unveiled image

Porsche has officially released the Panamera Diesel. It will be powered by a 3.0-litre common-rail turbocharged V6 putting out 246bhp at 3800rpm and 406lb ft between 1750 and 2750rpm.

It is only available with rear-wheel drive and an eight-speed Tiptronic S ‘box, does 0 to 62 mph in 6.8 seconds, and a top speed of 150 mph.

The vehicle comes with a wide range of standard features, including Porsche Vehicle Tracking System (VTS), leather interior, Porsche Active Suspension Management (PASM), Bi-Xenon headlights, front and rear ParkAssist, tyre pressure monitoring, automatic dimming rear view mirrors, Porsche Communication Management with touch-screen satellite navigation and audio controls, cruise control and a three year warranty.

The car will also be offered with optional low-resistance tyres; they help to extract an extra 1.5mpg and cut CO2 emissions to 167g/km.

Err, it’s £62,134, which isn’t what buyers on a budget were probably hoping for; it might be £649 less than a Panamera V6, but it’s still £15,796 more than a Cayenne Diesel. It’s not massively more fuel efficient than the Cayenne Diesel, but 43.5mpg makes this Porsche’s most economical car ever.

UK sales of the Panamera Diesel start in August 2011.
