Europe: Mercedes-Benz S-Class plug-in hybrid aiming at 81 mpg, on Euro hybrid cycle

Back in January, it was reported that Mercedes-Benz will offer the next-generation S-Class with a plug-in hybrid variant. At the time, insiders said that with the help of weight reduction and aerodynamic improvements, the S-Class plug-in hybrid sedan will be able to return an estimated 67 mpg.

In an interview with CARandDRIVER, passenger-car development boss Thomas Weber said that the Mercedes-Benz Vision S500 Plug-in Hybrid Concept shown in Frankfurt last year could achieve a fuel-economy of 78 mpg. He said that when the large luxury plug-in sedan hits markets it could hit at least 81 mpg (based on the European hybrid cycle).
