While speaking about the new BMW 1 Series M Coupe, Dr. Kay Segler, head of BMW's M Division, made a subtle comment confirming earlier speculation that the new generation BMW M5 will receive a turbocharged V8 powerplant.
"There is a lot more for BMW M fans to look forward to in the second half of 2011 as well. We will be presenting the next generation of the BMW M5 with V8 turbo engine. But let's talk about the details another time." said Dr. Segler.
Specifically, this is likely to be a boosted version of the current twin-turbocharged 4.4-litre V8 engine powering the current BMW X5 M and BMW X6 M.
The final power output is expected to be in excess of 420kW and 680Nm - making it far more powerful while being more efficient than the current BMW M5 which ended production just yesterday.
