Understand this, when people speak to high-revving M engines, it should be understood the engines must have the same flat and wide torque curve enabling use of the whole rev counter. That isn't a characteristic of current FI BMW motors, so those FI motors may rev to a respectable 7K rpms, but there's no point to rev them to redline in most gears as the power has gone way south by then. You're great at painting an incomplete picture. That's why there are so many holes in every argument you state.

Talk about painting a misleading picture!
The s63 engine puts out 500 foot pounds of torque from 1500 to 5650 rpm. The horsepower peak is at 6000 rpm. I'm reasonably certain that number will go north in the M5.

I'm reasonably certain the M5 will be the same motor as is. BMW seem to be minimizing variation these days. They've also figured out peak numbers can dupe the public into thinking these engines are more powerful than their best NA efforts. This board proves that.

Yeah unfortunately that is for real as Car and Driver stuck a camera on the side of the car and then went full throttle on X5 M. If you scroll down, you will see an M3 manual audio as well on the same page. I have actually heard an X6 M in real life in the first week of its release at the local BMW dealership and it had to be the worst engine/exhaust note I heard on an M car.

^^ Turbos mute the exhaust note.

The same applies to the engine note as well due to a much lower compression and slower piston speeds give them a "lazy character". Turbo motors make almost no soul stirring sounds at any rpm and make the driver want to fall asleep.
This is the upcoming M5 around Nurburgring: And here is the E60 M5:

Look at how fast it gets to 9000+ rpm (being driven by race car driver Scott Pruett). That is the beauty of highly engineered, high-revving engines with tons of compression and super fast piston speeds. Lexus is just getting in the game and they are coming with a bang since the LF-A is simply astonishing. BMW has been doing it for years and they built an amazing V10 in the M5. All they needed was a super light car weighing no more than 3300 - 3400 lbs and stash an updated more efficient version S65 V8 and V10 in the next generation. It would have improved everything. Instead, such a shame that BMW decided to pick the character-less, boring, bland low-compression engine with a turbo slapped on it route.

Only due to emissions. Certainly wasn't their desire, but they'll do what they have to do to sell cars, which is the necessity of it all.

There are many turbo engines that sound really nice IMHO - flat6s and 4s for one. The C5 RS6 V8 biturbo motor also sounds amazing, and the Audi v6 2.7 biturbo really sounded/sounds great too. There are many more examples, just as I'm sure there are many that sound muffled, farty, whatever. Of course, I think my M3 blows them out of the water though. I was literally laughing when I test drove the car for the first time. I said to my wife, "do you hear that engine - wow!". |

Just buy the fucking car when it comes out or don't, stop nagging. BMW will get more sales one way or another. Inductive reasoning has led them to believe FI >>> NA in sales. No one cares about a pretentious 330i driver who is enamored with NA.

Exactly what is wrong with this turbo car's exhaust note.
All a turbo does is alter the note you have to work with and it's up to the engineers developing the exhaust system to produce something special. |
