First speculated upon sometime last year, Mercedes-Benz has finally confirmed and introduced its latest engine – a new lightweight 5.5-liter twin-turbo V8 engine. Its intended use for now is to power AMG models and the new engine is set to power the S63 AMG beginning mid-2010.

Codenamed M157, the new 5.5-liter replaces Mercedes’ current 6.3-liter naturally aspirated V8 that has been powering such models like the C 63 AMG, CLS 63 AMG, E 63 AMG, S 63 AMG and the CL 63 AMG.

For the new M157, power is rated at 536bhp at 5,500rpm and peak torque stands at a massive 800Nm (590lb-ft) that has been made available at a lowly 2000rpm and 4,500rpm. The same 204kg engine with the AMG Performance Package will produce 563bhp and 900Nm (664lb-ft) of torque. Both engines will be mated to Merc’s 7-speed MCT transmission which helps improve average fuel consumption.

According to Autocar, another engine will also make its debut soon, a smaller 4.6-liter version that also sports two turbo’s will be used for the new CLS and S-Class models later this year.

Below is the official press release from Mercedes, read on for more information.

both turbo compressor outlets feed into an integrated air-to-water intercooler that resides within the phenolic? intake housing. it is the alloy box inside of the plastic housing in the top left image with the silhouette of the eight ovular intake port shapes above and below it...
