For the upcoming model year that starts from August 2010, Porsche has released a revised version of the V8-engined Panamera models (Panamera S, Panamera 4S & Panamera Turbo).
The Panamera has been made more efficient. A braking energy recuperation system is installed as a standard feature. Buyers may opt for a set of 19-inch all-season tires that come with reduced rolling resistance.
With these updates, the fuel consumption of the 500 hp Panamera Turbo has been reduced by 0.9 liters/100km. It now offers a combined driving cycle fuel consumption of 12.2 liters per 100 km (20.8 mpg). This combination of new features also resulted to a reduction in CO2 emissions by 21 grams/km.
A fuel consumption figure of 10.3 (22.8 mpg) by the Panamera S and 10.6 liters/100 km (22.2 mpg) by the Panamera 4S is now offered.
These figures indicate a 0.5 l/100 km reduction, and a 11 g/100 km CO2 emissions cut. According to the press release, the improved efficiency is a result of brake energy recuperation, with the battery being charged mainly during application of the brakes and in overrun.
Roll resistance is reduced and mileage is increased because of the enhanced tread of the tires as well as a special rubber compound. Another feature that was optimized is the Auto Start Stop function, enabling the driver to set off again even faster and more comfortably after coming to a halt.
Consumers can ask for the optional Porsche Torque Vectoring Plus (PTV Plus) paired with Porsche Dynamic Chassis Control (PDCC). Meanwhile, the V8-powered models also get a fully controlled rear axle differential lock.
