Is this new V10 the most powerful production motor BMW has made? Is the one the McLaren F1 uses have more horsepower?

The McLaren engine had 627 bhp, quite a bit more, but it would be hard to really call that a production engine. I think this is the most powerful roadgoing car BMW has ever produced by a large margin.

Yeppers. Also, you could say BMW's F1 engines are quite a bit more powerful then the McLaren F1, but those are manufacturered in even smaller numbers.

The engineers in their M division have some serious talent.

i think i'd still go with the e55, but this is promising. i like the fact that the engine will be NA.

Having a manual tranny makes it a winner in my book. Though I'd rather have forced induction and the torque that goes with it rather than a high revving peak output V10.
If an engine is designed properly, you can get the same torque from a given displacement, even if the redline of engine 1 and engine 2 are completely different.

high reving engine is nice...


As for the lloks, the rear is BEARFABLE, and the front is truely HIDEOUS. I would sell that dman thing and get an old e46 like NOW.

Agreed. I hope that once Chris Bangle is gone that all of his design ideas go with him.

How do Formula 1 engines make ~250lb-ft of torque at 20000RPM? Remember, displacement is limited to 3.0L.

Man that is one beautiful car! I would kill to drive one of those bad boys...of course..i do 90 to 100 in my Nissan Altima each day to work...one of these would have me tipping the speedo around 130mph all the time. :)

:confused:

He is absolutely correct. RPM does not equal torque, lol...

and.. ::Drool::.... 7 speed....

the hell
they should stick to a v8
it sounds so much better than a v10 too

400 HP from the current one isn't enough... LOL, and it's a freakin family sedan (basically)

Let me see if I can explain it... Well, if the displacement is the same, that means that there's the same amount of chemical energy in each cylinder (from the A/F charge). When combusted, there should be the same amount of pressure in the cylinder (ideal gas pressure/temperature relation). Now, if the redline of one engine is higher than the other, the bore is usually higher too. But, if bore is increased, stroke must be decreased, which leads to a decrease in the length of the lever arm (throw length - i.e. stroke/2). This means that torque should be decreased, as per the equation T = Fdsinx, but, because bore is increased, the crown area of the piston is also increased. The force exerted by a pressure (our hot, expanding gas in this instance) is equal to Pressure multiplied by Area (F = pa - not sure if those are the right symbols). So if pressure remains constant and area is increased, the force exerted on the piston is also increased. The increase in force should roughly balance out the shortening of the lever arm.

Mmm... Not too sure if that's clear or not.

Nice to see bmw returning to its old form of over-engineering its M-series cars. While the current 5.0 v8 is powerful, it's a diversion and it shared too much with the regular 5-series.
