Porsche has been giving some clues that it would expand its Panamera lineup to include a sporting wagon. But no hint was more obvious than when the German carmaker unveiled its Panamera Sport Turismo Concept at the current Paris Auto Show. The Panamera Sport Turismo concept features, for the first time, a plug-in version of Porsche's gasoline-electric hybrid system.
The Panamera Sport Turismo concept is one of at least three new Panamera-based models that Porsche is considering since launching the vehicle in 2009. Major visual modifications include an extended roofline, a longer glasshouse and an angled tailgate that opens at bumper height.
Porsche chief executive Mathias Muller is expected to confirm that new style-led wagon will become a part of the second-generation Panamera lineup. His confirmation is expected to coincide with the debut of the rival Mercedes-Benz CLS shooting brake at the Paris auto show.
Sharing the new Panamera's platform will be future Bentley models, as part of tighter engineering relationship between the two Volkswagen Group companies.
Panamera Sport Turismo concept also furnishes Porsche a potential four-door challenger to the Ferrari FF, which features a similar style but is a two-door vehicle. According to Muller, the body concept of the Panamera Sport Turismo provides a preview on a possible “Porsche sports car of tomorrow."
He, however, did not disclose any official time line for the launch of the production version. Sources close to the carmaker told Automotive News Europe that the new Panamera wagon would be rolled out in 2016, and will be produced at Porsche’s Leipzig plant, which also builds the Cayenne and will be building the upcoming Macan.
According to Porsche, it had already tried to develop a wagon from the current Panamera design, but they found the high cost of re-engineering the rear body structure to be prohibitive.
Porsche Panamera Sport Turismo’s drive technology realizes the next advancement step going to the direction of the plug-in hybrid. This is represented by the "e-hybrid" badge on the front wings. The vehicle's new electrical power grid charging ability has been fused with even more efficient components.
The concept automobile with its 416 hp (306 kW) of ultimate system power is intended to be driven in pure electric mode up to a speed of 130 km/h. It can travel distances of over 30 km. The Sport Turismo also shows remarkable fuel efficiency based on the NEDC standard. Its fuel consumption is less than 3.5 litres per 100 km, while CO2 emissions are under 82 g/km.
The new model’s drive system is a radical improvement of the parallel full hybrid that the vehicle already executes in the Cayenne S Hybrid and Panamera S Hybrid today. The latest electric motor yields about 70 kW (95 hp). This measurement is doubled as in the recent Porsche hybrid drive, while the three-litre V6 supercharged engine still yields 245 kW (333 hp) here.
In their teamwork, they step up the concept vehicle from zero to 100 km/h in a matter of six seconds or less.
Power pack: Li-ion battery with external charging capability
The model’s electric power pack includes a Li-ion battery which has better capabilities than that of the nickel-hydride battery which is now used in production, even though it almost has similar dimensions. Its energy storage capacity of 9.4 Kilowatt-hours and maximum optical power aid it to offer a more rapid acceleration, lengthier electronic driving options and faster speed when driven in the absence of the inner ignition engine.
