New Panamera S Hybrid is The Most Fuel Efficient Porsche of All Time

Just as we suspected when Porsche first announced its plans to present a brand new hybrid model at the Geneva Salon, the German firm's 'surprise' is indeed the Panamera S Hybrid. According to the automaker, the new 380HP hybrid GT is the most economical Porsche of all time with a combined fuel economy of 6.8 lt/100km or 34.6 mpg US, and also boasts the lowest CO2 output of any large sports sedan in the luxury segment with 159 g/km (both figures achieved with the optional low resistance tires).

The latest addition to the Panamera family makes use of the same powertrain found on the Cayenne hybrid mating a 333HP 3.0-liter supercharged V6 sourced from Audi to a 47 hp (34 kW) electric motor for a combined output of 380HP. Both motors are capable of powering the Panamera S Hybrid either alone or in combination, while the electric motor also operates both as a generator and a starter.

The electric motor is fed by a nickel metal hydride battery (NiMh) where the electrical energy recovered from braking and driving is stored. Power is transferred to the rear wheels by the familiar eight-speed Tiptronic S.

Porsche says the Panamera S Hybrid can complete the standard sprint to 100 km/h in 6.0 seconds (0-60mph in 5.8"), and reach a top speed at 270 km/h (168 mph). The range in purely electric mode is approximately two kilometres (1.24 miles) with electric driving possible up to 85 km/h (53 mph), depending on the driving situation.

When fitted with the optional lower-rolling resistance all-season tires from Michelin, the Panamera hybrid consumes on average 6.8 lt/100 km (34.6 mpg US.) with CO2 emissions of 159 g/km. With the standard tires, the hybrid model returns 7.1 lt/100 km (33.1 mpg US) with 167 g/km of CO2.

All Panamera S Hybrid models will come fitted as standard with the adaptive air suspension including the adaptive shock-absorber system with PASM, as well as a bespoke display concept that provides the driver with relevant information about the vehicle’s specific hybrid driving status.

The Panamera S Hybrid will enter the European market in June 2011 and cost €106,185 in Germany, including VAT and country-specific equipment, while sales in the States will start a little bit later in 2011 at a base suggested retail price of $95,000 excluding destination (€70,320).
