New BMW M5 in 2011 to get 550bhp - Page 4

I'd go for both and really knock the competition on their arse. That is what I expect BMW to do.

A lighterweight M5 with 600hp would force Audi to come up with a 700hp just to keep up, unless Audi focuses on their weight problem. Mercedes-Benz too.

You believe that man.. I mean come on. BMW has never been that power hungry in the past. 600 plus hp is pretty extreme when thay just broke the 500 mark with the current model.

On top of that with the addition of a bigger displacement, turbo chargers and other toys the car should be a bit heavier. If it`s going to be lighter the M boys have some work to do.

Not only was the jump from 400 to 500 in the M5's, the M3's new engine is lighter than the old straight six. So they have shown that it's possible to accomplish all these targets.

Also, if the only thing they do is bore out the engine, it's not going to add weight since the block is still essentially the same. I doubt this is all they are going to do though.

Agree. This would simply lower the weight ratio which should be the focus of the German super sedans. At some point the this hp war in Germany will soften. I really can`t see them breaking the 600hp mark with the next generation. Thats just my personl opinion. Efficiency should be the focus.

Lets see who gets there first.

That's only if the block can handle being bored out.

Agreed. However, Dinan already have a stroke kit that you can buy for your M5/6 albeit at a ridiculous price of $40k. It increases the capacity from 5.0 to 5.7 liters to get 628hp. If they can do that, then BMW can do something along that line with a 5.5 liter to get 550 hp.

However, that's just not going to fly I don't think. The engine will need more technology when the new M5 comes out.

Are you kidding me? $40k? Thats like nothing! No one would have said anything about that type of tuning costing €25k... cheap as hell! Im guessing the same kit would have been something like €50k ($80k) here.

Exactly. Here in Europe the kit would have been sold at €40k which is just as much dough as $40k is in the US. Not small money.

BMW CEO Norbert Reithofer has revealed in the past that future BMW powertrains will be downsizedin an effort to improve fuel-efficiency and reduce emissions, and that even the hallowed ‘M’ division could also be affected by the new wave of environmental consciousness sweeping the carmaker. BMW has always stood by the high-rev philosophy for delivering power from its M engines but that may be about to change.

Inside sources have revealed that the next-generation M5, due in 2011, will be powered by a high-performance twin-turbo V8 engine instead of a naturally aspirated V10. The source also revealed that initial tests of variations of the 400hp (298kW) turbocharged 4.4L V8 found in the X6 crossover is showing promising results, reports Automotive News.
Additionally, BMW’s M engineers are also finding good results from the award-winning 3.0L straight-six turbo. It comes “very close to a large-displacement, naturally aspirated engine,” the source told reporters.
Prototypes of the current M5 have been seen sporting front-mount intercoolers and additional air-intakes, confirming that a high-performance turbocharged powertrain is being developed. And, while purists may scoff at the idea of a turbocharged M car, the decision by rivals to launch forced-induction competitors such as the new twin-turbo RS6 and upcoming SL Black-Series, which is expected to get a twin-turbo V12, may leave BMW with little choice.
