Economical, powerful and low in emissions: that's the newly developed 4-cylinder petrol engines with direct injection in the E 200 CGI BlueEFFICIENCY and 250 CGI BlueEFFICIENCY. These primarily mainly impress with their direct responsiveness and smoothness of operation at all engine speeds. The E 200 CGI BlueEFFICIENCY has an engine output of 135 kW and maximum torque of 270 Nm, while the uprated E 250 CGI BlueEFFICIENCY variant supplies 150 kW and 310 Nm.
The low consumption figures for this new engine series are due in part to the relatively small displacement of 1.8 litres and turbocharger, as well as the improved CGI direct injection. By reducing the weight and the internal friction losses, the engine is particularly economical and meets the strict thresholds for consumption and emissions. From June 2010, the ECO start/stop function as standard in the E 200 CGI BlueEFFICIENCY with 6-speed manual transmission will also reduce fuel consumption and emissions by switching off the engine when the vehicle is standing still.
(E 200 CGI BlueEFFICIENCY: fuel consumption combined: 7.4-8.2 l/100 km, CO2 emissions combined: 172-190 g/km; E 250 CGI BlueEFFICIENCY: fuel consumption combined: 7.9-8.2 l/100 km, CO2 emissions combined: 185-190 g/km)[1]
Modern V6 technology is the basis of the new E 350 CGI BlueEFFICIENCY with direct injection. The petrol engine has a rated torque of 365 Nm at 3000-5100 rpm, delivers 215 kW and accelerates in 6.8 seconds from 0 to 100 km/h. Four-valve technology, variable camshaft control range for the intake and exhaust side, a two-stage intake manifold and a balancer shaft are amongst the technical details. The second generation of the Mercedes-Benz direct petrol injection with spray-guided combustion system and high-pressure direct injection via precise piezo injectors also ensures that the engine can function economically and with low emissions.

The E 500 is the most powerful engine for the new E-Class Cabriolet. The V8 engine has an output of 285 kW and develops a maximum torque rating of 530 Nm in the range between 2800 and 4800 rpm. Just 5.3 seconds are all this engine needs to accelerate the Cabriolet from 0 to 100 km/h – a peak value.
(E 500: fuel consumption combined: 11.0 l/100 km, CO2 emissions combined: 257 g/km)[1]
