The Porsche Panamera S Hybrid is acur- rently available. The four-door hybrid vehicle is also quick, with a 0 to 60 mph time of 5.7 seconds and a top speed of 167 mph. This is obviously a hybrid vehicle designed for the typical Porsche driver. Porsche is awaiting the official EPA fuel efficiency estimates for the Panamera S Hybrid but the vehicle has achieved 7.1 L/100 km (approximately 33 mpg) fuel ef- ficiency in European testing.AA By: Porsche Press Porsche Recruiting 100 Engineers for R&D Photos By: Porsche Press s part of an extensive personnel experts in the fields of electromobility, With this increase in staffing levels, recruitment campaign, Porsche lightweight construction, energy man- Porsche will take a leading role as a com- AAG is increasing the capacities agement as well as engine and chassis de- petence center for modern sports cars. of its development center in Weissach, sign.
