I'm traveling in Asia and recently picked up an issue of AUTOCAR. Here is what they said.

"The fourth incarnation of the definitive M-car, on sale in 2007, steps up a class. Not only is it bigger, with a higher spec and a higher price, but it's going to be more powerful too. Under the bonnet will be a new 406 bhp 4.0 litre V8 engine....Nothing's been officially confirmed yet though Gerhard Richter, head of development at BMW's M-division, recently revealed to Autocar that early development examples are 'significantly faster' than today's M3 around the Nurburgring's 14-mile Nordschliefe circuit, a benchmark for any new performance BMW....in keeping with M-car tradition, the styling changes over the standard 3-series are fairly subtle, but give the car an aggressive and distinctive look. The car's revised exterior has been created under M-division boss, Ulf Weidhas (not Bangle, thank goodness). The look is closely related to that of the larger M5, with a deeper front bumper, generously flared wheearches, chunkier side sills and a rear bumper that's shaped to draw hot air away from the car's hi-tech differential. Further classic M-division cues, such as the quad exhaust tailpipes leave little doubt about the car's origin.
The newly developed 48-valve 4.0 litre V8 is based on the M5's 500 bhp 5.0-litre V10....the result are claimed outputs of 406 bhp and 309 lb-ft of torque (numbers that are better than those of 911 Carrera S!!!). compared to the existing M3's 3.2 litre inline 6-cylinder engine, that's up by 63 bhp and 40 lb-ft. With pistons cast from aluminium and other lightweight internal components, the new engine is said to retain the M3's charcteristic highly strung nature, and should be capable of reving to 8250 rpm....because the new V8 is shorter than today's straight-six, BMW has been able to shift it backwards in the engine bay, mounting it further towards the M3's centre line-a factor that promises to improve weight distribution and endow the car with superb handling....Autocar sources also confirm that BMW has recently signed a contract with German transmission maker ZF for the supply of a new double clutch gearbox, as developed by VW, which shifts faster than a conventional automatic.
Underpinning the M3 is a heavily upgraded version of the 3-series' suspension, with MacPherson struts at the front and a multi-link arrangemet at the rear. The 3-series' basic geometry remains unaltered, but the components have been optimised by making many of them from lightweight aluminium to sharpen responses. It is unsure whether the next M3 will adopt the adaptive damper system found in the M5, although it does look likely to have 19-inch wheels as standard.
The head of M-division, Ulrich Brunke, indicates that BMW is keen to broaden the appeal of the M3 in the face of increased competition from the likes of the hard-charging Audi RS4, MB's C55 AMG and Cadillac CTS V-spec. The m3 will be launched as a coupe, with saloon, cabriolet and estate versions to follow. Also planned is a follow-up to the hardcore M3 CSL, complete with lightweight carbonfibre panels and an even more powerful engine, though 2009 is the very earliest you can expect to see it. It's too early to be talking about pricing in any real detail, but the move to V8 power is expected to raise the M3's price-from today's $ 41,155 to close to 44,000 when UK sales get underway in mid-2007.....
BMW plans on filling the territory occupied by the current M3 models with a new 1-series model, the 135iT, to complement the recently announced 130i. Powered by a 330 bhp turbo-charged 3.0 litre inline six-cylinder, this car will become the most potent 1-series.'

So i guess we are looking at approx 2 years before we can get our mitts on the new e90 M3 ??? :(

:clap: :clap: :clap: .. ouw yess. the big v8.. 2007 eyy? should give me enough time to play around with my e46. im looking forward to wat it looks like really, i have no doubt in the engine/performance section, i wish it was out now, my plate woudl be "997THIS".. lol

2 years to see an e90 m3 and another 4 years.. to see a CSL version. i wonder if the the CSL will make it over the pond this time?

Really looking forward to hearing more about the next M3 Coupe but 6 valves per cylinder? Not so sure thats accurate. M5 engine has 4 valves...

i think that statement about 6 valves per cylinder says alot about the accuracy of the article

thanks Krazy... I guess it kind of says what we all have thought... I wish it was just a year off, that’s the only part I don't like... I'm going into the corner to cry now

Ya, I did the math on the 48 valve six per cylinder and was like wtf. :hmm:

Are there any cars, race or production, that have 48 valves with a v8 configuration? I know there are some with engines with 5 valves per piston, but 6?

Not quite sure how you can "improve" the weight distribution either. Aren't E46 M3's less than 1% off a perfect 50/50?

Really you want as much mass as possible near the COG so you can improve the MMI (mass moment of inertia) about the roll, yaw and pitch axis which will help the car change direction faster and be more controllable. So its not the pure location of the COG thats important.

Imagine a 50t block of steel with wheels at each corner it has a 50/50 weight ditribution but its not going to be easy to go through fast switch back etc.

What are the saloon and estate versions supposed to look like? Like are they four door models or what??

It means that either it will have really small valves that restrict airflow, or hugely bored cylinders or that they are just have no clue what they are talking about. I am taking option 3. Anyone else with me?

50/50 weight can be improved by bringing the weight closer the centre of the car ie at the moment a lot of the electronics + the battery are moved to the boot (trunk) to balance out all the mass at the front. For handling even weight near the centre is better than even weight at the edges

You know its mostly a marketing thing though.

I was sitting here doing the same... it even had me doubting my basic division skills!!! :nixweiss:

I think the article hit a few major points, and if not confirmed, predicted the same things we have been predicting here... so I think we're on the right track.... but yea, the 6valve thing definitely discredits this article

weight distribution, front/rear % 50.3/49.7

I have now seen several HP estimates... R&T said 380 HP while some other rags are stating 400 HP. Which would be correct?

well ,not interested unless its 450 hp+ or realy light

It's true that BMW's are near perfectly balanced fore-to-aft, but the positioning of the weight is also important. Weight stacked nearer the center of the car lowers its moment of inertia -- this is why a Boxster is so damn fast in the twisties.

You could have all the weight at both ends of the car and still be balanced 50/50, but it won't swap ends as willingly.
