Hot on the heels of the new E-Class, Mercedes has released details of the high-performance E63 version, which will make its official debut at the New York Auto Show on April 8th.
The new model retains the 6.2-liter V8 found in the previous generation, and gets just a slight bump (of 11hp) in performance to 518hp and 465 ft-lbs of torque. To help get that power to the ground AMG has equipped the car with the new AMG Speedshift MCT 7-speed automatic transmission, first used in the SL63. Using a multi-disc wet start-up clutch, instead of a traditional torque converter, shift times are just 100 milliseconds in "M" (Manual) mode.
Another reason for the speedy shift times is that AMG has programmed the ECU so that under full load gear shifts, the ignition and fuel injection are interrupted.
The engine and tranny combine to deliver a 0-60 mph time of just 4.4 seconds!
Oh, and the the transmission does rev match on the down shift and have a Race Start or "launch control" function.
In total the transmission has four settings: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport Plus) and "M" (Manual).
The Controlled Efficiency setting also works with several other technologies to reduce overall fuel-consumption by 12 percent compared to the previous model. The Controlled Efficiency mode will give early up-shifts to keep engine speed as low as possible, while AMG has developed a way to "detach" the alternator from the engine so that it doesn’t drain power when it isn't needed.
