In place will be a new seven-speed transaxle gearbox, as opposed to the one currently utilized on the SL63 AMG. Mounted at the rear axle and encompassing the differential, the new gearbox is a dual-clutch automated manual transmission – one that that will shift gears by itself or at the driver’s command. Connecting the engine to the rear-mounted transaxle is a torque tube housing a lightweight carbon-fiber composite driveshaft, just one of the various components that help the SLS achieve a curb weight of 3,571 lbs (that's nearly 300 lbs lighter than the SLR McLaren). The end result when mated with the AMG 6.3-Liter V8 is a 0-62 mph time of 3.8 seconds, while top speed comes in at 196 mph. There's no word yet on pricing for the model, although early reports indicate the Mercedes SLS AMG will likely be in the $250,000 range
