2014 Porsche Panamera S E-Hybrid Returns 53.45 MPG in Initial Test Drives

Porsche Panamera S E-Hybrid Out For Test Drive

The fuel efficiency of plug-in hybrids, at least in terms of MPG, largely depends on the distance to be drive, the miles of electric-only range of the vehicle and the  ability to recharge along a route.

Therefore, it’s difficult to say that plug-in hybrid X gets Y-ish MPG and that plug-in hybrid A gets B-ish MPG.

The variables are ever-changing, especially out there in the real world.

We premise it this way because Porsche has published the first real-world MPG figures for its Panamera S E-Hybrid.  Porsche plug-in hybrid sedan was recently driven  by journalists and the MPG results are in.

All the nitty-gritty details of the first test drives are described by Porsche below:

“Stuttgart. 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 kilometres – the model consumed just 4.4 l/100 km 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. 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. And it even accomplished this in four unmodified Panamera S E-Hybrid production cars, each carrying three to four persons, with the climate control system activated and accelerating up to 230 km/h on the motorway section of the route. 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.”

In terms of MPG, the results of the 42 test drives averages out to 53.45 MPG.

Unfortunately, Porsche doesn’t say how often the plug-in Panamera was charged, or if it even ever was during the 28.7 km loop.

We’ve purposefully left these figures in metric, because Porsche offers up this additional info, which shed some light on the overall fuel efficiency marks achieved in these tests:

“The car’s range of 36 kilometres in all-electric driving was also confirmed in practice with a fuel consumption value of 0.0 l/100 km and zero local emissions, which was not only attainable in NEDC testing on a dynamometer, but also on the street. And it even attains this value at an average speed of 54 km/h, while the average speed in NEDC testing is just 33 km/h.”

The Panamera S E-Hybrid will be at dealers in mid-Summer 2013.  Its base MSRP of $99,000 represents only a $6,000 premium over the non plug-in version of the Panamera S.

    Clearly they recharged the battery before each test drive to obtain the 53mpg.

    1200 km = 745 miles / 42 drivers = 17 miles per driver

    The plug-in hybrid has a max EV range of 22 miles, so topping off after each test drive is the only way each driver can benefit from the vehicle being a plug-in.

    But with this vehicle, along with the Audi plug-in and Cadillac ELR coming this year and next…..it would be so easy for Lincoln to offer the MKZ Energi plug-in with 21 EV miles and below $50k.

  2. I’m not sure why talking about MPG on a plugin hybrid is so hard: how many miles did they go on electricity, and then what MPG did they get after the charge was depleted? How much of a charge does the battery hold? What is the Wh/mile in electric mode, and what is the MPG in hybrid mode?

      Agreed. Any change Porshe’s numbers are in hybrid mode?! 🙂
