42 journalists who had the honor of being invited by Porsche to what was called a “Plug-In Hybrid Technology Workshop” found themselves used as lab rats, and to produce a mileage rating that supports Porsche’s published results for the hybrid Panamera. It didn’t quite work out that way. Says a Porsche press release:
”On the occasion of an international press event – in which over 42 test drives were conducted with journalists in the Panamera S E-Hybrid covering a total distance of over 1,200 kilometers – the model consumed just 4.4 l/100 km (53.5 mpg) averaged over all drives. The top value recorded on the circuit course for the world’s first plug-in hybrid in the luxury class was a low 2.8 l/100 km (84 mpg). These results illustrate that in real everyday operation, it is entirely possible to attain fuel consumption values of the same magnitude as the value determined in NEDC testing, which is 3.1 l/100 km.”
On a strictly non-EPA conversion, the average 4.4 l/100 km would equate 53.5 mpg. The top value of 2.8 l/100 km converts to 84 mpg. Porsche’s published 3.1 l/100 km rating would convert to 75.9 mpg. For the unwashed, NEDC refers to the New European Driving Cycle, which supposedly mimics the typical usage of a car in Europe, which it gloriously doesn’t.
The circuit, and the usage profile also were slightly atypical. According to Porsche, “the test circuit, which had a total length of 28.7 km, followed a course through and around the city of Hockenheim and comprised 6.5 km city driving, 9.2 km of country roads and 13 km of German Autobahn – some without speed limits. A prerequisite for attaining such values is systematically exploiting opportunities for charging the 9.4 kWh lithium-ion battery on the electrical grid.”
Great, in the meantime, we exploit opportunities to show pictures of the Panamera in a Stau, in a picturesque village, and in use. We also ask our Porsche-insider Doug Demuro for an inside view.
