Mercedes has unveiled their SL AMG lineup. The SL 63 AMG puts out 525hp compared to the 612hp of the SL 65 AMG.

Just weeks after releasing the freshened SL’s, Mercedes is finally prepared to unveil their AMG cousins. Powered by an AMG V8 that puts down 525hp and 630Nm of torque, the freshened SL 63 AMG should have no problems keeping up with its competitors given that it goes from 0 to 62 mph in 4.6 seconds.  Debuting on the SL 63 is AMG’s newly developed SPEEDSHIFT MCT 7-speed sports transmission, which ditches the conventional torque converters and replaces it with a wet compact start-up clutch. This allows for a direct connection to the powertrain, providing for an engaging driving experience. The Multi-Clutch Technology only employs the clutch elements to perform gearshifts and offers four drive modes, double-declutching and Race Start function.

The range topping SL 65 AMG cranks out an outstanding 612hp and 1000Nm of torque thanks to a massive biturbo six liter AMG V-12 engine. The SL 65 continues to use the AMG SPEEDSHIFT five-speed automatic, which is good for a 0 to 62 mph time of 4.2 seconds

Both feature an updated exterior fitted with AMG specific body modifications, performance tires, and improved braking systems. Interior changes are relatively minor but include a new ergonomic sports steering wheel and optional AIRSCARF.
