Are you implying, you will pay MORE to hear a 6 cylinder in a GTR or Porsche than a m3/4?

I really don't have a huge problem with 6-4 cylinder engines. but for expensive cars i feel they lack sound. when comparing to V8s.

Yes if the car offers a crazy amount of performance for the money, then i can live with it being not my favorite type of engine. like a GTR.

Porsches are just great cars.

Where you get your info is beyond me. I would not believe half of anything you read online or in magazines.

Liking the sound of this.

Wait a sec, I recently got information from a legitimate source as well tied to the engineering department in Germany as well. Wtf! That's not what I was told.

Either way, don't shoot the messenger, I think I'm going to sit this discussion out till September when we know for sure. I'm done here.

Hasn't it already been established that the motor will have a 414 hp / 395 lb-ft power output? This came from the official VIN information.

It's been established that BMW has built and registered M3s whose output is officially quoted at 415hp. It has not been established that the production model will have that specification.

The problem is that the VIN database technique of discovering specs is new. No one knows if, in the past, BMW preproduction models found therein always match what was eventually delivered to the public. And even if they have, we still don't know if that will hold true on this case.

Personally, I think the specs are probably a good bet, but I am not complete convinced just yet.

So you are 3rd person, BMW Engineering>your source>you? That more and better information than you provided prior.

Come on, don't pack up your things and leave. No one is being disrespectful here. There is just a lot of natural skepticism.

I don't buy the other posters rumors any more than yours...

Mother of god man. I hope you are right.

460-475hp with an e46 target weight?!?!? If that's true I'm sold!!

Honestly, is this such a big deal? E46 target weight is apparent, but would you not purchase it if it had 415 BHP? BMW underrates their turbo engines pretty badly. Not to mention a tune, exhaust, and a midpipe (altogether would cost what, around $5k?) would boost it to about 500 BHP easily.

I don't get this obsession with numbers and figures. I'm starting to think people want the extra horsepower just so they can go around claiming it has that much power (and no GIdriver, I'm not saying you're like that, just that some people are starting to seem like it).

I think the only arguable matter regarding the new M3/M4 is the sound of the car. It just doesn't sing and appeal to me anymore! Let's just hope aftermarket exhausts come sooner rather than later that make it sound better and give it good HP gains.

Could end up costing 30k if the engine malfunctions. The vast majority of owners keep their engines stock to avoid invalidating the 4 year warranty which is included in the price.

As for the sound, I'm going to wait until the final production version can be heard before passing judgment.

In short: NO (with all due respect).
And yes, I believe some numbers are important. And no, I do not go around bragging about numbers, I take my car to the track.
Why would a car enthusiast complain about having more power and less weight?

By your last sentence, then, are we to conclude that more than half your post is, shall we say, B.S?

Since we're speculating on the number of turbos, can we speculate on the tunability as well? Sorry if this is off tangent LOL

With turbos on the exhaust side of the straight 6, I would think this would leave room for various turbo upgrades? Unlike on the V8 whose turbos are in the V of the motor (doesn't leave much room).

I was opposed to turbocharging at first, but after seeing the numbers the Horsepower Freaks E46 M3's are putting out, I think I'm starting to change my mind!

a 450hp+ engine is something I trust BMW to get right. Make it fun to drive and light on its feet? Now that is something I am not sure I can expect. I hope I am wrong.

I think you will be. The F30 is c.800 pounds lighter than the bloated F10.
