REPORT: Twin-turbo 5.5-liter V8 to replace Mercedes-Benz' 6.2-liter V8

While Audi and BMW have embraced turbocharging, Mercedes has -- by and large -- stuck with large displacement, naturally aspirated engines. However, If a recent report is to be believed, that's set to change late next year.

Insideline quotes Daimler AG Group Research & Mercedes-Benz Cars Development board member Dr. Thomas Weber as saying the big 6.2-liter V8 powering Mercedes' AMG lineup will be replaced by the end of next year by a twin turbocharged 5.5-liter V8. And that's not all. Under Mercedes' reported plan to downsize its powertrains, all V8s will shrink in size for 2011, with turbocharging making up for the power deficit. If true the move to smaller displacement engines would help increase efficiency while also reducing CO2 emissions.

While the report only mentions V8 engines, we're guessing there's a good chance Mercedes could use more turbos in its V6 product lineup as well. The move will help the German automaker meet more strict emissions laws in both Europe and the U.S., while giving the torque-craving masses what they need.
