AMG's new twin-turbo 5.5-liter engine may soon trickle down to the E63, according to a recent report by German magazine Auto Bild. Horsepower could be rated at 518, but an available performance package should increase that to 549 horsepower. The 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 lb-ft of torque on the base E63 AMG and up to 125 lb-ft on the E63 with a performance package, since the E63 has always closely mirrored the CLS63’s output.
The big news here is the increase in horsepower and torque, which should be similar to the P31 development package recently offered on the C63 AMG with the 6.2-liter V8. In the past, the performance 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.
