Outstanding smoothness and power delivery combined with modest fuel consumption and exhaust emissions. That is the profile of the 6-cylinder V-engines in the CLS.

The CLS 300 is now available as an entry-level model. It delivers 170 kW and impresses with its eager responsiveness, while complying with the EU5 exhaust gas standard. The CLS 350 CGI revs up even sportier: with an output of 215 kW and maximum torque of 365 Nm, it accelerates in 6.7 seconds from 0 to 100 km/h. But the CLS 350 CGI also makes for big excitement with its economy as it injects the fuel at high pressure directly into the combustion chamber using special piezo injectors.

(CLS 300: fuel consumption combined: 10.0–10.2 l/100 km, CO2 emissions combined: 233–237 g/km; CLS 350 CGI: fuel consumption combined: 9.1–9.3 l/100 km, CO2 emissions combined: 217–222 g/km)[1]

The CLS 500 has the inimitable effortlessness of an 8-cylinder engine. With an output of 285 kW and a muscular torque of 530 Nm, the V8 engine accelerates the CLS 500 from 0 to 100 km/h in just 5.4 seconds. What's more, it does all this while complying with the strict EU5 exhaust gas emissions standard.

The CLS 63 AMG requires only 4.5 seconds to accelerate from 0 to 100 km/h. Powered by a 6.3-litre naturally aspirated V8 engine with 378 kW and with an impressive torque of 630 Nm, it transforms itself into a high-performance sports car – with the comfort of a sporty saloon.
