Mercedes-Benz SL63/65 AMG (R231)

2013 Mercedes-Benz SL65 AMG

The SL-Class R231 served as the sixth generation of the legendary GT car made by Mercedes-Benz and here, that wouldn't be done without the mega erotic AMG models.

Starting with the SL63 AMG, this version comes with the M157 5.5L V8 BiTurbo engine that churns out 395 kW (537 PS) of power and 800 Nm of torque. Mated with the AMG SPEEDSHIFT MCT 7-speed transmission, it will do 0-100kph in 4.3 seconds and a top speed of 250 km/h. Couple that with the optional AMG Performance Package and the top speed will become 300kph thanks to the boost of power and torque.

The AMG SPEEDSHIFT MCT 7-speed transmission comes with several driving modes such as "S" (Sport), "S+" (Sport Plus), "M" (Manual), and "C" (Controlled Efficiency). When set to "S" (Sport) mode, the engine and transmission take on a much more agile character. "Sport plus" or "Manual" shifts the gears another 25 percent faster than in "S". The new Controlled Efficiency ("C") mode makes convenient gearshifts and a "soft" accelerator response set-up for outstandingly smooth power transfer.

There's also the ECO start/stop function that shuts the engine off when stopped and then starts again when the foot is on the gas pedal, to save petrol.

In the past, old Mercedes-AMG models bearing the 65 nameplate are using the old M275 6.0L V12 BiTurbo which packs more power but only comes in 5-speed AT because 7G-Tronic wasn't able to handle the torque from the V12 engines. For the first time ever in Mercedes-AMG history, the new SL65 AMG is the first ever Mercedes-AMG model to have the all-new M279 6.0L V12 BiTurbo engine mated with the AMG SPEEDSHIFT MCT 7-speed transmission.

This new V12 BiTurbo engine for the SL65 AMG generates 463 kW (630 PS) of power and 1000 Nm of torque. 0 to 100 km/h takes 4 seconds with the 200 km/h mark attained after just 11.8 seconds. The top speed is 250 km/h (electronically limited).

Exclusive features on the SL65 AMG are AIRSCARF, Active Parking Assist incl. PARKTRONIC, ATTENTION ASSIST, Bang & Olufsen BeoSound AMG high-end surround sound system, COMAND Online with 6-disc DVD changer, Anti-theft alarm system, Frontbass, Remote-unlocking boot lid incl. power closing for boot lid, Intelligent Light System ILS, KEYLESS-GO Convenience package, Convenience telephony, MAGIC VISION CONTROL, NECK-PRO head restraints, Panoramic vario-roof, PRE-SAFE system, Door power closing, and Automatic pop-up roll-over bars for driver and front passenger.

The SL63and SL65's available colors are; Diamantweiss, Iridiumsilber, Dolomitbraun, Cavansitblau, Schwarz, Perlbeige, Palladiumsilber, Obsidianschwarz, Feueropal, Magnetitschwarz, and Tenoritgrau.

My comment:
The new SL63 gets the now ubiquitous M157 V8 BiTurbo engine, the kind of engine that Forza Motorsport creators are afraid to feature in any single Mercedes-AMG model with that kind of engine in the future, and the new SL65 AMG is the first ever AMG model with the V12 BiTurbo engine mated with the AMG MCT SPEEDSHIFT 7-speed transmission.

At last, Mercedes-AMG finally managed to tame this GT car with big power and it will surely give the new BMW M6 a run for its money.
