As a way to meet the new fuel economy standards set by the Obama administration, requiring fleets to have an average of 35.5 mpg by 2016, Porsche unveiled the 2012 Panamera S hybrid before the Geneva Auto Show. The car should get about 34.5 mpg, which is pretty great considering the car produces 380 horsepower and can go from 0 to 60 mph in 5.7 seconds. Clearly the most fuel efficient Porsche, the Panamera S hybrid has a top speed of 167 mph, and rides in purely electric mode for approximately one mile (which is obviously not very impressive!)

The new hybrid uses the same gasoline engine/electric motor combination found in the Cayenne S Hybrid and has a regenerative braking system that recharges the cells during braking. According to a statement from Porsche:

The Porsche parallel full hybrid system also reduces consumption at high speeds thanks to its ‘sailing’ or coasting mode. When the driver lifts off the accelerator at normal highway cruising speeds, the gasoline engine is completely switched off and disengaged from the drivetrain by a decoupling clutch. This eliminates the combustion engine’s drag forces and braking effect in the interest of lower resistance, fuel consumption and emissions. As soon as the driver presses the accelerator, to pass another vehicle for example, the gasoline engine smoothly starts within fractions of a second and engine rpms are increased to match the current vehicle speed. It does this seamlessly thanks to the Hybrid Manager, which also helps the Panamera S Hybrid accelerate dynamically in gears at higher speeds much like a conventional Panamera.

For those of you who have the need for speed, with an eco twist, the Panamera S Hybrid will go on sale in the United States later in 2011 for about $95,000 (excluding destination).
