At a press conference hosted by Bridgestone Corporation and the New York International Auto Show, the Mercedes-Benz S 250 CDI BlueEFFICIENCY was declared the 2012 World Green Car. The Mercedes-Benz S 250 CDI BlueEFFICIENCY was chosen from an initial entry list of 23 new vehicles from all over the world, then three finalists: the Mercedes-Benz S 250 CDI BlueEFFICIENCY, the Ford Focus Electric, and the Peugeot 3008 Hybrid. This is the second time in World Green Car history that a Mercedes-Benz technology has won this prestigious honour. The Mercedes-Benz E 320 BlueTEC technology was the 2007 World Green Car winner.
Prof. Dr. Thomas Weber, Board of Management, responsible for Group Research & Mercedes-Benz Cars Development observed that, "The highly efficient gasoline and diesel engines in the S-Class show that our customers can drive a luxury vehicle with a clear conscience. The S250 CDI is the most impressive example: with a fuel consumption of only 5,7 l per 100 km, the S250 CDI is the most fuel-efficient luxury sedan in the world."
The S 250 CDI BlueEFFICIENCY, is the first four-cylinder engine in the more than 60-year history of success of the S-Class, the highly-efficient turbo diesel unit achieves fuel consumption levels of just 5.7 litres per 100 kilometres in the NEDC cycle, which corresponds to a CO2 output of 149 g/km. The luxury saloon accelerates from 0 to 100 km/h in 8.2 seconds, and reaches a top speed of 240 km/h. The combination of exemplary economy with a high level of driving dynamics is achieved thanks to the latest generation of common-rail technology, two-stage turbocharging with high and low-pressure turbochargers, and also the standard-fit ECO start/stop function, which Mercedes-Benz is offering in conjunction with the new, extensively revised 7-speed 7G-TRONIC PLUS automatic transmission.
