Mercedes-Benz has released details regarding its new lightweight 5.5-litre twin turbo V8 engine. The engine was speculated upon late last year and now is confirmed as reality. It will be used in certain AMG models, the first being the S 63 AMG from this summer.

The new 5.5-litre, codenamed the M157, replaces the current 6.3-litre (6208cc) naturally aspirated V8 which has been doing duty in cars like the C 63 AMG, the CLS 63 AMG, the E 63 AMG, the S 63 AMG and the CL 63 AMG.
Power is rated at 400kW (544 PS / 536 bhp) at 5,500rpm and peak torque is a massive 800Nm (590 lb-ft) made between 2,000rpm and 4,500rpm. An even more powerful version with the AMG Performance Package of the 204kg engine will produce 420kW (571 PS / 563 bhp) and 900Nm (664 lb-ft) of torque. Both will be mated to Merc's 7-speed MCT transmission which helps the less powerful model achieve 26.9mpg (UK) in average fuel consumption.
According to Autocar, a smaller 4.6-litre version of the engine, also sporting two turbos, will be used for the new CLS and S-Class derivatives later this year.
Hi-res photos will be added later. See press release below for full details.

 

what about the G55 ?? dont u guys think they'll use the new 5.5 twin turbo engine ?

 

I hate turbos. They cook up the engines so you have to maintain it more frequently and the engine doesn't last as long. It's a step backwards in my mind.

 

I highly doubt it

 

Yea, the turbo porsches they've been producing for years successfully is a great testament to that

Turbos are awesome!!!

 

C63 will probably get a detuned one.... but once unleashed.... I bet this thing can get 650+ HP with just chip/exhaust!!

 

Can't wait to see these motors perform!

 

This engine is going to be a monster!

 

what!! You must be high

 

love it!

 

ooooh baby, these come straight out of a tuners dream

 

Yes indeed.

 

Now benz needs to make a black series version of the new e-class coupe and stick this under the hood

 

Nice.

 

As others have eluded to... this is a ridiculous statement
