Could be replaced by a hybridized V8 4.0

Mercedes-Benz will allegedly drop the twin-turbo V8 5.5-liter after the current-gen S63 AMG.

The M157 is a Euro 6-compliant twin-turbo V8 5.5-liter gasoline engine outputting 585 bhp (436 kW) and 900 Nm (664 lb-ft) in the 2014 S63 AMG. According to AMG chief Tobias Moers, the mill cannot receive a power hike without a negative impact on its reliability.

He refused to mention if other S-Class models will receive this engine but it is believed the AMG versions of the forthcoming coupe and convertible will also get it, along with updated versions of cars which already have this engine, like the CLS 63 AMG and E63 AMG.

Chances are we won't see it in the next-gen E-Class (due in 2016) or other brand new models outside the S-Class family. The all-new C-Class will get an AMG version powered by what is believed to be a V8 4.0-liter developed by bonding two 4-cylinder 2.0-liter turbocharged engines from the A45 AMG. The same power unit is expected to reside under the hood of the 911 competitor known internally as the C190 which will probably receive the SLC moniker.

CarSales believes big AMG models will feature a hybridized version of the aforementioned V8 4.0-liter engine based on Moers' statement according to which hybrid and electric power are part of AMG's future.

I hope the greenpeace goes to hell, and money for big guys will soon be made by making big-and-bad cars. Then I'll see how everybody talks crap about hybrids! Just leave the AMGs alone, will you?!

So two remarks: this is not what I call being proactive. What are their middle term vision? Totally no sense to release an engine with a so limited evolutions way. Second what about the tuners? Does it mean Bravus and so on would be sold no reliable cars?!!!

... but then again, that engine will come in 3+ years, possibly by then hybrid systems will be more advanced and lighter then current ones, in that case it would make sense to do that.

This doesn't sadden me, the 5.5 V8 M157 engine is in my CLS 63, and while the car has amazing performance and economy, it's lost that aural quality in day to day driving that the old naturally aspirated engine was so famous for. Hell, it doesn't even sound anywhere near as good as my A45 (note: with sports exhaust), in the cabin. I really hope the next one brings back some of that roaring/barking noise, even if some of it has to be mechanically engineered.

But why? Were looking at probably the most efficient petrol powered V8 ever fitted to any car right now. It dosen't need any more improvement as its impressive as it is. The hybrid would only add weight and blunt the performance

This is good news. We should see more hybrids coming in the near future.

Only thing hybrid system does is add weight.
