It's no surprise that BMW plans to attempt to bring its uber-saloon up to AMG-levels of power when the new M5 debuts in 2011. That means that output needs to surpass the current model's paltry 501 hp, so BMW will bore out the current V10 to 5.5-liters, slap on a couple of turbos and use direct-injection to bringing power levels up to 550 hp, or more. Grunt will be shoveled to the rear wheels via either a six-speed manual transmission or the new seven-speed M DCT dual-clutch 'box.
But it's not all about pavement-pummeling power. The use of the twin-turbochargers and DI is as much an attempt to reduce emissions as it is to boost output, and BMW is intent on making the next 5-series, due out in 2010, one of its most fuel-efficient vehicles. That means that start-stop technology will be used on the engine, along with its Efficient Dynamics system that uses regenerative braking to reduce load on the alternator, improving both fuel economy and engine output.

      "It's no surprise that BMW plans to attempt to bring its uber-saloon up to AMG-levels of power when the new M5 debuts in 2011."

      Nice of you to conveniently forget that the CTS-V will make at least 550 hp.

      So boring it out , adding direct injection and 2 turbo's only nets another 50hp??

      C'mon BMW.. u can do better than that.. seems like a hell of a lot of work for nothing.
        • 6 Years Ago
        I know right! Seriously under reporting...
      • 6 Years Ago
      It'd be a lot cooler if they left it with the same engine but made the entire car lighter....The hp wars are just getting more and more ridiculous. Happy that Subaru and Nissan finally took a step in the right direction of making their performance cars SMALLER and adding basically no hp.

      Uh, hasn't the M group always been naturally aspirated engines? Haven't they come out to say that M cars would always be naturally aspirated?
      • 6 Years Ago
      That'd be an nice achievement - more power and more efficiency.

        BMW = Bring My Wallet

        Why are they so overpriced here in the North America... oh yaeh, I remember... because there are people stupid enough to pay for it... okay, nevermind... keep going.
        • 6 Years Ago
        You think BMW's are overpriced in America? Haha
        • 6 Years Ago
        Yeah, possibly the most disappointing improvement on a bi turbo setup I've ever seen. And per the start-stop, were it not available to everyone right now, I'd be a bit more impressed. As it stands, neither does anything for me.

        Keep up the great work you started with the x6 bmw!

        That's not AMG levels, guys.

        That's CTS-V levels.

      Too bad the car will probably still be ugly.

        have you seen the rear of an M6 Dick? it even has its own nickname (Banglebutt)

      If the current 5.0 liter engine makes 500 horsepower, and BMW plans to enlarge it to 5.5 liters, why do they need turbos to make 550 horsepower? Doesn't make much sense.
        • 6 Years Ago
        A bump by a half a liter and adding turbos to get 50HP? I'd say this information is simply wrong.
        • 6 Years Ago
        I agree. Using DI, Twin-turbos and extra bore will allow this engine to achieve much higher HP numbers than just 550. I'm thinking 650+...
        • 6 Years Ago
        look at the current 3l twin turbo, only makes 300 hp. nissan toyota, mitsubishi, they have all made 300 hp tt 3 liters as well. the difference is that the turbos (i'm sure) will significantly increase the low end and midrange power. the turbo 6 has a great power curve, although peak numbers are not very impressive.

      I dont get why people think the bangle'd bmws are ugly i mean the past bimmers are freakin rectangles! All the younger people like how the new bimmers look its modern! and as for idiots still complain about idrive how hard is it? its so damn easy!! its like old people who cant figure out how to work a digital camera or anything new. die off already the new generation is here, you've been replaced

      I read the article in Autocar, and I agree the headline was confusing, but it didn't say that the next M5 will get a turbo'd V10.
      What it actually says is that the next M5 will get a bored-out 5.5l version of the current V10, which should produce 550hp (as you'd expect). But the generation after that BMW is planning to switch to a turbo charged motor.

      Who cares about 2011? The world will be doomed in 2012 anyways...
      • 6 Years Ago
      Who CARES??? What is the point..Is anyone ever going to use this much power? They have created a car that maybe 5 people will want or have the money to buy. Big deal.
      • 6 Years Ago
      Engine start and stop WITH turbos???

      I hope it has electric oil and water pumps that stay on and continue to feed the turbo's lube and coolant jackets.

      Stopping flow to the turbos will coke them up like crazy, because turbos may still be hot and free-wheeling even if the engine itself stops.

      DI, twin turbos, valvetronic... all that sounds great. Start-stop, not so much.

        MK, curious...what car is that in your avatar pic?
        • 6 Years Ago
        That is my 2005 Subaru Legacy GT 2.5 Turbo 5-speed.

        It is small enough that it is a bit challenging to see.
