Back in 2007 when BMW released the 335i fans and enthusiasts bitched and moaned about the new cars being fitted with a twin turbo set-up as opposed to the naturally aspirated straight-6 engine that 3-series owners were accustomed to. They wondered if performance would suffer due to turbo lag and if there would be increased under hood temperatures due to the new set-up. Then they drove it and that’s really all it took for them to realize that BMW did their homework. The current E60 version of the BMW M5 is powered by a big V10 that delivers 500 hp and 384 lb-ft torque. Sure these are impressive numbers but when you consider that the car weighs in at over 4000 lbs. you begin to realize that it needs every bit of that power to make it competitive in the market segment.
Fast forward now to 2012 and the soon to be released redesigned BMW M5. Since the E60 came out there has been speculation as to what the next generation car would be powered by. Would it be another V10 or perhaps a V8? The automotive press has been speculating for quite some time now. To get an idea though of what would be under the bonnet we really didn’t have to look any further than the M5’s AWD brother, the X6 M. The X6 M debuted in 2009 and is powered by a twin-turbo 4.4-liter V8 that delivers 555 hp and 500 lb-ft torque. Saying this car is a hammer is an understatement, as it not only bests the M5’s hp rating but the torque as well. Aside from that it showed a clear indication of where BMW was headed in the engineering department with it’s twin-turbo V8 set-up.
Now it seems that all the speculation over what is going to power the new 2012 BMW M5 can be laid to rest. BMW’s M boss, Dr. Kay Segler has stated that the new engine will be the same unit found in the BMW X5 M and X6 M. Odds are though that the big twin turbo V8-mill will have a different tune and most likely get a bump in power to the 600 hp range, after all it wouldn’t be good form for an SUV to have more umph than BMW’s super sedan now would it.
