| 2012 Mercedes-Benz CLS63 AMG |
Despite a significant performance increase compared with the previous model, which had a naturally aspirated AMG 6.3-litre V8 engine producing 514 hp and 630 Nm of torque, the new Mercedes-Benz CLS63 AMG is some 32 per cent, more economical - which represents a quantum leap forward.
The NEDC fuel consumption of 28.5 mpg equates to a CO2 output of 232 g/km. Thanks to these figures, the new V8 Coupé from AMG not only undercuts all of its direct competitors in the small but refined four-door high-performance coupé segment, but is also more fuel efficient than significantly lower-powered vehicles. Both performance variants have identical fuel consumption and CO2 figures.
Exclusive: AMG SPEEDSHIFT MCT 7-speed sports transmission
A major contribution towards achieving the unrivalled consumption figures has been made by the AMG SPEEDSHIFT MCT 7-speed sports transmission, a component used exclusively at Mercedes-AMG. Unlike a conventional automatic transmission, the MCT transmission does away with the torque converter; instead, it makes use of a compact, wet start-up clutch. Also fitted as standard equipment is the stop/start function: it is permanently active in the transmission's Controlled Efficiency ("C") mode, and switches the eight-cylinder engine off when the car comes to a stop. At the same time, "C" mode also means a "soft" accelerator response set-up with convenient and early gearshifts; moving off generally takes place in second gear. A green "ECO" symbol in the AMG instrument cluster shows the driver that the stop/start function is active.
The engine and transmission come across as much more agile in the "S" (Sport), "S+" (Sport plus) and "M" (Manual) modes; in addition, the stop/start function is switched off. In "S" and "M" modes, the engine management system partially suppresses the cylinders: interrupting ignition and injection under full load leads to even faster gearshifts than before. The highly emotional vocals are an appealing side effect of this lightning-fast process. An automatic double-declutching function and RACE START function are also included as standard.
