Mercedes-Benz CL65 AMG
Among engine specialists and car enthusiasts, a twelve-cylinder engine has always represented the crowning glory of the engine builders' craft. A very special example of this luxurious engine series is the AMG 6.0-litre V12 biturbo engine, as used in the S 65 AMG and CL 65 AMG. Just one glimpse of the engine specifications is enough to reveal why: with a displacement of 5980 cubic centimetres, the AMG V12 generates 463 kW (621 hp) at 4800 rpm. The maximum torque of 1000 Nm has been electronically limited - from a possible 1200 Nm - to make allowances for the powertrain, and remains constant between 2300 and 4300 rpm.
The performance is evidence of the exceptional power: both AMG V12 models accelerate from 0 to 100 km/h in just 4.2 seconds, and are capable of hitting a top speed of 250 km/h (electronically limited).
AMG has made a number of additional detailed enhancements to the AMG 6.0-litre V12 biturbo engine for the new model year. The inlet diameter of the compressor housing and also the exhaust gas ducts have been enlarged, and the resulting increase in air throughput. The maximum charge-air pressure is 1.5 bars.
Despite the increase in output, it has still been possible to reduce fuel consumption and exhaust emissions: the NEDC-combined fuel consumption of both models is now 14.3 liters per 100 kilometers, which equates to a reduction of 0.2 liter per 100 km. CO2 emissions are 334 grams per kilometer (previous model 346 g/km).
The reduction in fuel consumption is achieved thanks to the new engine electronics and generator management: the kinetic energy generated during each drive phase of the engine and also when braking is used to charge the battery, and not just left to generate heat as would otherwise be the case. In all other operating areas, management of both the on-board electrical system and generator enables the generator to be maintained at a low voltage level.
The new CL 65 AMG now features an even more exclusive appearance than ever before. An enhanced status is guaranteed thanks to the swept-back front section with profiled bonnet, the enlarged, more angled radiator grille and the powerful headlamps. Included as standard is the Intelligent Light System (ILS) with bi-xenon headlamps, active light function, Adaptive Highbeam Assist and AMG-specific LED daytime driving lights in the front apron. The upsized, chrome-trimmed cooling-air intake adorns a distinctive horizontal grille slat. The newly designed AMG bodystyling is easily recognizable thanks to the distinctive v-shape and the lower cross strut, which on the CL 65 AMG has an exclusive chrome-look finish. This is matched by the AMG rear apron which boasts a diffuser insert which is also finished in chrome. Also new are the tail lamps with one-piece red-colored cover plates and the reversing headlamps placed next to the license plate recess. Another visual highlight comes in the form of the AMG sports exhaust system with two chrome twin tailpipes featuring a V12 design.
When viewing the vehicle from the side, enthusiasts will discover not only the
"V12 BITURBO" lettering on the mudguards, but also AMG double-spoke forged wheels, painted titanium grey and with a high-sheen finish. The wheels are fitted with 255/35 R 20 tires at the front, and 275/35 R 20 tires at the rear.
he exclusive position held by the CL 65 AMG within the AMG model range is also highlighted by the vehicle's exquisite and perfectly finished interior appointments: the Exclusive PASSION nappa leather upholstery with its distinctive AMG V12 diamond pattern design covers all four seats as well as the door centre panels. Nappa leather also covers not only the entire instrument panel and seatback panels, but also the magazine pockets and the parcel shelf. In addition, Alcantara® is used on the roof lining and also on the A and C-pillars. The AMG sports seats, which can be adjusted into many different positions, feature their own seat upholstery layout as well as active ventilation and heating, and also come with the Seat Comfort package: it includes active multi-contour front seats with massage and dynamic functions, and also NECK-PRO luxury head restraints. Also fitted as standard on the front seats is the PRE-SAFE® positioning function.
New additions in the interior include the AMG sports steering wheel with silver-colored aluminum shift paddles and perforated nappa leather in the grip area. The latest information and entertainment comes courtesy of the standard COMAND APS multimedia system including Harman Kardon® Logic 7® surround sound system with SPLITVIEW – which divides the screen into different displays based on viewing angle.
The AMG instrument cluster displays the expressive "AMG V12 BITURBO" start screen and a 360-km/h speedometer scale. Integrated into the AMG main menu is a gear indicator including upshift recommendation, and the driver is also kept informed about engine oil and coolant temperatures. Thanks to the RACETIMER, lap times can be displayed, such as when on a race track for example. A particular highlight of the interior is the exclusive analogue clock with IWC design. High-gloss poplar wood trim elements, reserved exclusively for the V12 models, complete the interior look.
