Apparently, giving the E 63 AMG a new face like the rest of the updated 2014 E-Class range that will bow at next week's Detroit Motor Show and adding its 4MATIC all-wheel drive as an option wasn’t enough for Mercedes-Benz's performance division.
The Affalterbach crew fiddled around with the E63 AMG's twin-turbocharged 5.5-liter V8, too, increasing its boost pressure from 0.9 to 1.0 bar. As a result, it now it puts out 550HP (557PS) and 531 lb-ft (720 Nm) of torque, an increase of 32HP and 15 lb-ft (20 Nm) over the outgoing model.
Since the standard E 63 AMG, which is available in saloon and estate forms, now has the same ponies as the previous car's optional AMG performance pack, they’ve also added the S-Model option that’s available with all-wheel drive and increases power to 577HP and torque to 590 lb-ft (800 Nm).
The standard model accelerates from 0-100 km/h (0-62 mph) in just 4.2 seconds, a figure that drops to 3.7 seconds (3.8 for the estate) in 4MATIC versions. The S-Model is a tenth of a second quicker, completing the sprint in 3.6 seconds for the saloon and 3.7 seconds for the estate, while all models have their top speed electronically limited at 250 km/h (155 mph).
