Forced Induction? // 2011 M5

With rising fuel costs, BMW may be making a few changes in the coming years. Take the M5 for example. Some 500 odd horsepower, more computer than car, mammoth four door saloon, all of which makes for a great ride, but a not so great fuel economy rating. So what is the Bavarian motor company to do? Recycle of course! Nothing does the trick quite like a massive turbocharger (or a pair for that matter). Word has it, the next incarnation of the M5 will utilize turbochargers and a few less cylinders then the current V10 offering. Maybe the 4.4L twin turbo V8 out of the X6 xDrive50i? They have it running at 536bhp currently, and with comments like "it can do more" we don't suppose they are stopping there. Audi's RS6 and its 580bhp might be the benchmark, but when fuel economy suddenly becomes an issue, BMW might consider dropping a few pounds before cutting horsepower. Consider the in line six bi-turbo, suitable engine, proven and worthy of a place between the fenders of an M5. We will see. Stay tuned // 07.07.2008
