According to German automobile magazine Auto Bild the Mercedes-Benz E63 AMG will soon get the new twin-turbo 5.5-liter V8 with an available performance package that boosts the total horsepower to 549. Output will be 518 horsepower sans the package, which is the same number as the outgoing 6.2-liter engine.
The new twin-turbo engine has been gradually replacing the 6.2-liter normally aspirated V-8 across the AMG lineup, and it appears the E63 is next in line.
These horsepower numbers are lower than the 2012 CLS63 AMG fitted with the new turbo eight that we tested earlier this year, which is rated at 525 horsepower and 516 pound-feet of torque; the performance package bumps it up to 557 horsepower and 590 pound-feet of torque. Auto Bild’s report didn’t include torque numbers, but we estimated an increase of 51 to 125 pound-foot respectively, since the E63 has always closely mirrored the CLS63’s output.
The big news here is the increase in horsepower and torque, which was never a part of the performance package in the E63′s outgoing naturally-aspirated 6.2-liter engine or the 2nd-gen E55 AMG with the 5.5-liter blower V8 engine. In the past, the package, which cost anywhere between $8-10,000, only included track and aesthetic enhancing upgrades such as a stiffer suspension, carbon-ceramic brakes, higher top speed and multi-piece rims.
The new performance package is reported to cost around 8,300 Euros, roughly $11,800. We expect more details to surface sometime during the New York Auto Show.
