SL 63 AMG (R 230)

AMG dream machine with a revolutionary transmission and a 386 kW/525 hp V8 engine

Emotional performance courtesy of cutting-edge engineering: the new Mercedes-Benz SL 63 AMG in a nutshell. The roadster is powered by an AMG 6.3-litre V8 engine developing 386 kW/525 hp and 630 Newton metres – which makes it today’s most powerful model with a V8 naturally aspirated engine in its class.

The SL 63 AMG comes exclusively with the all-new, innovative AMG SPEEDSHIFT MCT 7-speed sports transmission. The newly developed power transfer concept features a compact, wet start-up clutch that replaces the conventional torque converter. The resulting direct connection to the powertrain, together with the double-declutching and Race Start functions, guarantees an extremely emotional, supremely dynamic driving experience. The SL 63 AMG sets new standards in the open-top sports car segment thanks to this outstanding drive combination and the retuned, even more agile AMG sports suspension based on Active Body Control.

SL 63 AMG with Performance Package from the AMG PERFORMANCE STUDIO

The AMG SPEEDSHIFT MCT 7-speed sports transmission is an all-new, unique concept, available exclusively in the new Mercedes-Benz SL 63 AMG. It combines the best of two worlds: the sporty, direct and agile feedback of a manual transmission and the maximum convenience of an automatic transmission. Fitted with seven speeds, four drive modes, a double-declutching and Race Start function, the AMG SPEEDSHIFT MCT 7-speed sports transmission offers unprecedented versatility. MCT stands for Multi-Clutch Technology and only employs clutch elements to perform gearshifts.

Individuality: AMG SPEEDSHIFT MCT 7-speed sports transmission

Mercedes-Benz SL 63 AMG (R 230), 2008

The AMG SPEEDSHIFT MCT 7-speed sports transmission is an all-new, unique concept, available exclusively in the new Mercedes-Benz SL 63 AMG. It combines the best of two worlds: the sporty, direct and agile feedback of a manual transmission and the maximum convenience of an automatic transmission. Fitted with seven speeds, four drive modes, a double-declutching and Race Start function, the AMG SPEEDSHIFT MCT 7-speed sports transmission offers unprecedented versatility. MCT stands for Multi-Clutch Technology and only employs clutch elements to perform gearshifts.

No interruption in torque and four drive modes

At the heart of the new AMG SPEEDSHIFT MCT 7-speed sports transmission lies the wet start-up clutch, which runs in an oil bath and replaces the previous torque converter. Thanks to its low rotational inertia, the transmission responds
instantaneously and dynamically with no slip. Accelerator pedal movements trigger an instant traction response.

Mercedes-Benz SL 63 AMG, (R 231), 2008Fitted with four drive modes, the transmission provides gearshifting with no loss of tractive force and supports customised control strategies for maximum driving pleasure. In “C” mode the gearshifts are comfortable, coupled with a “soft” accelerator response set-up for outstandingly smooth power transfer. In “S” mode the engine and transmission interact with more “bite”: the engine speed is allowed to reach a higher level in each gear; the downshifts also feel more spontaneous. The gearshifts are around 20 percent faster than in “C” mode. Switching to “S+” mode cuts another 20 percent off shift times, while “M” is the sportiest mode: here the AMG 6.3-litre V8 engine has even more bite, added to which the transmission shifts gear another 10 percent faster – a reduction of 50 percent compared with “C” mode. In “M” mode the gearshifts take just 100 milliseconds.Mercedes-Benz SL-Class, SL 63 AMG, R 230

Ultra-fast, spontaneous multiple downshifts are another forte of the new MCT sports transmission. For instance, kickdown lets you move straight from seventh down to fourth gear or from fifth to second. In the “S” (Sport), “S+” (Sport plus) and “M” (Manual) modes the automatic double-declutching function is active. And this not only adds to the driver’s emotional experience: the virtually load-free downshift minimises load-change reactions, which pays dividends particularly when braking into a bend on the racetrack.

New AMG DRIVE UNIT with innovative Race Start functionMercedes-Benz SL 63 AMG (R 230), 2008

The new AMG DRIVE UNIT is the central control unit for the AMG SPEEDSHIFT MCT 7-speed sports transmission and all driving dynamics functions. On the left next to the selector lever is the electronic rotary switch to select the four drive modes including activation of the new Race Start function. Underneath are three buttons for additional functions: the first controls the ESP® function, the second the ABC suspension system. The third adorned with AMG lettering is used to store the selected transmission drive mode and the suspension set-up. Briefly pressing the AMG button brings up the configuration options, while holding down the button allows you to program the required set-ups.The Race Start function takes driving dynamics to an entirely new level: it enables the SL 63 AMG driver to call on maximum acceleration, while ensuring optimum traction of the driven wheels. The optimum start-up engine speed is set fully automatically and the SL 63 AMG accelerates away in an instant – even up to maximum speed if required. The driver does not need to shift gear manually; the AMG transmission changes gear with lightning-fast shift times.

AMG 6.3-litre V8 naturally aspirated engine with 386 kW/525 hp

US version SL 63 AMG

The AMG 6.3-litre V8 engine teams up with the AMG SPEEDSHIFT MCT 7-speed sports transmission to form a perfect partnership for dynamic driving pleasure and outstanding performance. The SL 63 AMG accelerates from 0 to 100 km/h in 4.6 seconds before quickly going on to a top speed of 250 km/h (electronically limited). The high-revving, naturally aspirated engine generates 386 kW/525 hp at 6800 rpm from a displacement of 6208 cubic centimetres, delivering maximum torque of 630 Newton metres at 5200 rpm. The unique combination of highrevving concept and large displacement achieves the best of both worlds: high pulling power at low engine speeds coupled with exhilarating high-revving flexibility – right up to 7200 rpm.The AMG V8 is packed with a wealth of fascinating racetrack technology, including the lightweight, extra-rigid closed-deck crankcase and cylinder walls with a revolutionary TWAS coating as well as the valve train designed for high engine speeds with bucket tappets in the cylinder heads. The vertical arrangement of the intake and exhaust ports together with the variable intake manifold featuring two integral throttle flaps results in superlative cylinder charging and high power output.The sophisticated electronically controlled fuel supply provides a consummately spontaneous response to accelerator movements in all driving situations; the AMG sports exhaust with two oval, chromed twin tailpipes guarantees the characteristic AMG V8 vocals. The tri-metallic coating used in the catalytic converters results in a faster response from a cold start, more efficient emission control as well as superior long-term durability. The SL 63 AMG fulfils all standard exhaust emissions limits such as EU 4 and the specific requirements of the U.S. market (LEV-II, On-Board Diagnosis II and oxygen sensor diagnosis).

AMG sports suspension based on Active Body Control and 3-stage ESP®

The dynamic drive unit finds its perfect match in the SL 63 AMG suspension. The AMG sports suspension based on Active Body Control has been further enhanced and not only comes with new spring and damper tuning but also completely modified elastokinematics. The front axle bearings, the spring links and the torque strut along with individual strut bearings at the rear have been retuned to deliver greater agility and shorter stopping distances. In partnership with the optimised speed-sensitive power steering the SL 63 AMG now feels even more direct and livelier. The AMG sports suspension based on Active Body Control also enables the suspension set-up to be customised. At the push of a button, the driver can select a sporty, firm response with reduced roll angles, or go for a comfort-focussed setting for excellent comfort on long journeys.Also new is the 3-stage ESP® with sports function. This system provides three different settings and is the logical development of the AMG ESP® philosophy. The driver can choose between the settings “ESP ON”, “ESP SPORT” and “ESP OFF” by pressing the ESP® button in the AMG DRIVE UNIT – the activated setting is shown in the central display in the AMG instrument cluster.
