2011 Mercedes S250 CDI BlueEfficiency

Mercedes S250
Mercedes has unveiled at the Paris Auto Show the S 250 CDI BlueEFFICIENCY, the world’s most fuel-efficient luxury sedan. It is powered by four-cylinder turbo engine that delivers 204 HP and 500 NM of torque and delivers a total of 5,7 liters engine per 100 kilometers. The car sprints from 0 to 60 mph in just 8,2 seconds and can hit a top speed of 150 mph.

The engine is mated to ECO start/stop system. This system shuts down the engine as soon as the vehicle comes to a stop – e.g. at traffic lights – and the driver continues to press the brake pedal while it is stationary. The engine starts again immediately as soon as the driver releases the brake pedal or presses the accelerator pedal.

The ECO start/stop function will not switch the engine off for example if the desired interior temperature has yet to be reached, if the driver has switched off the system or if drive programmes "S" or "M" are active. An intelligent control system ensures that all functions and comfort systems otherwise remain in operation during the stop phase.

With the new S 250 CDI BlueEFFICIENCY, Mercedes-Benz is presenting the world’s most fuel-efficient luxury saloon at the Paris Motor Show 2010. As 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. As a result, the new S 250 CDI BlueEFFICIENCY is the first 5-litre car in the luxury segment and at the same time the first vehicle in its class to undercut the 150-gram mark in terms of CO2 output. With a peak output of 150 kW (204 hp) and a maximum torque of 500 Nm, the four-cylinder CDI also guarantees a superior driving experience which is typical of the S-Class.

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.

The 150 kW (204 hp) engine in the latest S-Class variant already features in numerous Mercedes-Benz models, boasting outstanding efficiency. The maximum torque of 500 Nm is available from an engine speed of just 1600 rpm.
