Going on sale from August 2011, the Porsche Panamera range has been extended with the introduction of the new Panamera Diesel. The new engine gives the luxury four-door, four-seater a potential range of 745 miles on one tank of fuel.
The long distance performance is delivered by a 3.0-liter V6 engine with a rated output of 250hp between 3800rpm and 4400rpm. The maximum torque of 400 lb-ft is available from 1750rpm to 2750rpmr.
The engine is only available with rear-wheel drive and uses an efficient eight-speed Tiptronic S transmission as standard. The six-cylinder turbo-diesel engine powers the new Gran Turismo from 0-62mph in 6.8 seconds, with a top speed of 150mph.
The Panamera Diesel offers a highly appealing driving range of more than 745 miles on one 21 gallon US tank, emits 172g/km and delivers a Combined fuel economy of 36mpg US.
With the optional lower rolling resistance tires, efficiency improves further, to 167g/km and 37mpg US on a Combined cycle.
The V6 engine is state of the art in diesel technology. It includes common-rail direct injection through piezo valves at a pressure of 2000 bar. It also has electrically controlled variable geometry turbochargers (VGTs) and emission control achieved by exhaust gas recirculation, oxidation catalyst and particle filter.
An additional contributing factor to the low emissions is the auto start/stop function, which is fitted as standard.
Adaptive air suspension is available as an alternative to the standard steel spring suspension, to provide an even wider range of suspension settings to extend the driving qualities further still.
The new model is recognized by the 'diesel' lettering on the front doors.
