the corvette had a similar system that was key operated via a switch in the dashboard ,it shifted from 280 to 400 bhp

From what I have heard, the new M5 has only 400hp until one presses a button on the dash which unleashed the next 100hp. Why? This seems really stupid. If a driver doesn't want all 500hp, then just don't press the throttle pedal all the way. The car has traction control - it's not a safety issue. When the driver really needs all 500hp to avoid a problem or merge quickly onto the highway, then he has to take his attention off the road to press a stupid button - that makes no sense. My only conclusion is that it's either a stupid gimmick or BMW hopes that its engines won't explode as often as the E46 M3 motors if its drivers leave the car in the 80% power mode

Has BMW ever considered building engines that don't blow up instead?

I don't believe what you guys are saying
Do you really think BMW would build an unreliable car with 500Hp???? I don't think so, BMW knows this beast will cruise the German highways at full power in the hands of future owners who are used to do that in regular basis.

Well, they built a grenading 343hp motor for the M3 that is regularly driven at 250kph on the autobahn...

Yeah, I mean prior to the E46 M3, they had some of the most reliable and long-lasting motors in the industry (including M-series). It's a shame the cars are getting heavier, uglier and less reliable all at the same time

At least BMW admited the engine problems and sent letters to their owners informing them about it, something Porsche didn't do. Ever since 98 that the M96 engines have been blowing too, just look at any Porsche forum and almost regulary there are stories of blown engines from the 1997 Boxster to the 2004 996. And for those Porsche owners who had their warranty period expired with a blown engine on his hands the headhackes are not soft at all. Instead of critisize the great achievement BMW made with an almost race engine into a mass production car at fair price, we should worry about Porsche Policy of dropping palid engines on their mitic sports car, the Carrera 911.

J Seven - I think if you look at the number of posts that I have you'll see that I spend far too much time here. Honestly, I know of almost no engine failures other than RMS leaks - this is often solved by replacing the engine, but it does not mean anything other than some oil leaking - not a dangerous failure like the M3. Can you direct me to a post where someone has reported an internal engine failure?
As far as the M5 goes - yes I love power (don't care much about high-tech features though), but I also like low weight, steering with feedback, attractive designs, and reliability...

Grant, I guess it's the same kind of issue as some Porsche owners(997) complain about, the Sports Chrono Package. If the car can perform like hell by pressing "sport" button why not mapped the ECU this way to begin with.
It doesn't change the power but the response changes a great deal.
I guess the "Button" is becoming a trend among sports cars manufacturers.

Ron, there is an easy explenation for the 997 chrono sport setup: not all customers want to have it, as unbelievable this might sound. I recently met somebody at my dealer who did a 997 Carrera S testdrive and who didn't like the chrono sport package at all (funny, he liked the stop watch... ). He found the throttle response with active sport button to be too aggressive and too spontaneous. Not to forget about the changed PSM mapping which would probably put a lot of 997 owners in huge trouble. It is pretty spectacular to see a car with activated PSM system drifting around curves.
But I agree that the chrono sport package (without the stop watch) should have been a standard option on the 997.

Ouch! Well neither of these stories bodes well for modern German engines. I truly hope the rumors about the new M5 are false and I'm fairly confident that the serious problems (other than RMS) are uncommon on the 996/Boxsters.

and if you want 500Hp, just press the button, as you press the on/off radio button, i can't see what's wrong with that.

Then the electronics will keep track of the activation time. Owners activating this button a little too often might have a lot of explaining to do when it comes to warranty repair! We have already seen this with the M3 SMG launch control.
