In the model series of the new CL the completely newly developed 8-cylinder engine ensures the most outstanding capability in every driving situation.

The displacement and consumption and in turn the emissions figures have been significantly reduced compared with the predecessor model while also increasing the output. The 8-cylinder unit impresses with a wealth of technological highlights such as direct petrol injection with spray-guided combustion and twin turbochargers.

The CL 500 BlueEFFICIENCY with 320 kW develops a maximum torque of 700 Nm and achieves a top speed (electrically limited) of 250 km/h. With the integral ECO start/stop function you also save on fuel when waiting at a traffic light or in a traffic jam. The function recognises when the engine is not needed and automatically switches it off.

In the CL 63 AMG the new AMG 5.5-litre V8 biturbo engine achieves an output of 400 kW and a maximum torque of 800 Newton metres. This is made possible by a unique combination of high-tech systems, for example direct petrol injection, twin turbochargers, energy recuperation from braking and the Controlled Efficiency drive programme with stop/start function. In conjunction with the AMG Performance Package the figures increase to 420 kW and 900 Newton metres. A look at the performance diagrams shows that no other engine in this output class achieves the figures delivered by the new AMG biturbo.

(CL 500 BlueEFFICIENCY: fuel consumption combined: 9.5–9.9 l/100 km, CO2 emissions combined: 224–232 g/km; CL 500 4MATIC BlueEFFICIENCY: fuel consumption combined: 9.9–10.1 l/100 km, CO2 emissions combined: 237–242 g/km; CL 63 AMG: fuel consumption combined: 10.5 l/100 km, CO2 emissions combined: 244 g/km)[1]

Cutting-edge engine technology empowers the CL 600 to rapidly develop its strength. Our top-of-range power unit, the V12 biturbo has a maximum power output of 380 kW and maximum torque rating of 830 Nm. It also displays outstanding response characteristics: the V12 biturbo develops its maximum torque rating from 1800 revolutions per minute and maintains it up to 3500 revolutions per minute. The CL 600 has two turbochargers and intercooling to thank for such excellent values.

To save weight, the cylinder heads are made from die-cast magnesium. 3-valve technology improves airflow and, thanks to dual ignition, further optimises combustion.

It is hard to believe, but the massive power of the CL 600 has been further increased - the CL 65 AMG is here. The sporty top-of-the-line model awaits you with a 6.0-litre V12 AMG biturbo powerplant which produces 463 kW and a maximum torque of 1000 Nm.

(CL 600: fuel consumption combined: 13.8–14.0 l/100 km, CO2 emissions combined: 322-328 g/km; CL 65 AMG: fuel consumption combined: 14.3 l/100 km, CO2 emissions combined: 334 g/km)[1]
