The successful Mercedes Benz C 63 AMG is now more attractive than ever: the modified design of the top-of-the-range C-Class model is complemented by numerous enhancements to its technology which deliver even more driving enjoyment while significantly improving fuel consumption.
The introduction of the AMG SPEEDSHIFT MCT 7-speed sports transmission with the 'Controlled Efficiency' mode as standard along with a new power steering pump help to improve the combined NEDC fuel consumption by about ten per cent to 23.5 mpg (Estate: 22.9 mpg). The output of the Mercedes Benz C 63 AMG's 6.3-litre V8 engine is unchanged at 457 hp and can be increased to a maximum of 487 hp with the optional AMG Performance package. Agility, grip and ride comfort have been enhanced as a result of numerous measures to optimise the AMG sports suspension. New assistance systems and a new generation of telematics with internet access increase both safety and comfort.
The top Mercedes Benz C-Class model boasts a wealth of new technology including the AMGSPEEDSHIFT MCT 7-speed sports transmission. Rather than using a torque converter, this innovative transmission has a wet start-off clutch which allows it to deliver a much more efficient, agile and direct response. Fuel consumption and emissions have been reduced significantly thanks to the 'Comfort' mode and a new power steering pump: at 23.5 mpg (Estate: 22.9 mpg) the combined NEDC fuel consumption of the Mercedes Benz C 63 AMG sees about a ten per cent improvement over that of the previous model. CO2 emissions figure is now 280 (Estate: 288) grams per kilometre. Both power variants have identical fuel consumption and emission figures.
The AMG SPEEDSHIFT MCT 7-speed sports transmission impresses with its exceptional flexibility: with four driving modes as well as double-declutching and RACE START functions it is as compatible with a relaxed, fuel-saving driving style as it is with high-speed laps on a closed racing circuit and extremely dynamic overtaking manoeuvres. The Comfort 'C' mode is programmed to provide early, comfortable upshifts while maintaining the lowest possible engine speed to help the driver keep fuel consumption down. The 'S', 'S+' and 'M' modes deliver increased agility through fast, responsive gear changes and higher revs. Gear changes in the 'S+' and 'M' modes take just 100 milliseconds.
The naturally aspirated eight-cylinder engine with its large displacement of 6208 cc develops 457 hp at 6800 rpm and attains a peak torque of 600 newton metres at 5000 rpm. A look at the performance figures confirms that the new Mercedes Benz C 63 AMG retains its predecessor's position as the top performing model in its segment: acceleration from standstill to 62 mph in just 4.5 seconds (Estate: 4.6 s) while the top speed is 155 mph (electronically limited).
Even more dynamic performance is available with the optional AMG Performance package: this offers 487 hp and allows a 0-62 mph acceleration time of 4.4 seconds (Estate: 4.5 s). The Mercedes-AMG engine experts have achieved this increase in output thanks to a technology transfer from the Mercedes Benz SLS AMG: the forged pistons, connecting rods and the lightweight crankshaft all come from the gullwing model's engine. The reduced mass inertia of the components - which are three kilograms lighter than those of the standard version - allows the naturally aspirated eight-cylinder engine to rev up with even greater ease and agility. Models equipped with the performance package can be identified by the variable intake manifold painted in titanium grey under the bonnet, the AMG high-performance braking system with composite front discs and red painted brake callipers all round, the carbon-fibre spoiler lip on the boot lid (Saloon) and the AMG performance steering wheel in nappa leather with an Alcantara grip area.
