Economical, powerful and low in emissions: that's the newly developed E 250 CGI BlueEFFICIENCY. The 4-cylinder in-line engine with direct injection is characterised by its smoothness of operation across all engine speed ranges and has an output of 150 kW (204 hp) and a maximum torque rating of 310 Nm. Its low consumption figures are due in part to its engine concept, which is based on a comparably small displacement of 1.8 litres, and includes turbocharging. The saving in weight and reduced inner friction losses mean that the engine functions highly economically and can comply with the stricter limits on consumption and emissions. The optimised CGI direct injection system also promotes economic engine usage.

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 (292 hp) and accelerates in 6.3 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.

(Provisional figures: E 350 CGI BlueEFFICIENCY: fuel consumption urban: 12.3-12.4 l/100 km, extra-urban 6.3-6.6 l/100 km, combined: 8.5-8.7 l/100 km, CO2 emissions combined: 199-203 g/km)[2]

The E 500 is the most powerful engine for the new E-Class Coupé. The V8 engine has an output of 285 kW (388 hp) and develops a maximum torque rating of 530 Nm in the range between 2800 and 4800 rpm. Just 5.6 seconds are all this engine needs to accelerate the Coupé from 0 to 100 km/h – a peak value.

(Provisional figures: E 500: fuel consumption urban: 16.1 l/100 km, extra-urban 7.8 l/100 km, combined: 10.9 l/100 km, CO2 emissions combined: 254 g/km)[2]
