WORLDCARFANS.COM - - Only weeks after BMW revealed their M3 Concept (http://www.worldcarfans.com/news.cfm/newsid/2070306.023/country/gcf/BMW/bmw-m3-concept-car-unveiled) car in Geneva, they have released detailed information about the new V8 engine that will go into the production model. We are currently waiting for an English translation of the entire kit, and as soon as we receive it, we will publish. However, in the mean time here are the main facts:
22% more power
8% less fuel consumption
Displacement 3,999 cm3
Power 309 kW/420 HP
Torque 400 Nm/295 ft-lb @ 8,300 rpm
Double VANOS with 8 individual throttle butterflies for more spontaneous reaction time
Fulfills EU4 and LEV 2 emission requirements in Europe and US respectively
Brake Energy regeneration with intelligent regeneration
Weight 202 Kg (15kg lighter than S54 Inline 6 cylinder)Despite an additional two cylinders, BMW has reduced the weight of the engine to be 15kg lighter than the cast steel S54 inline 6 cylinder in the previous generation E46 M3. Through advanced construction techniques and the use of aluminum block and composite materials the engine weighs a mere 202 Kg.

Although the torque figure is uninspiring, 85 percent of the maximum torque (340 Nm/250 ft-lb) is available from 2000 rpm up to 6,500 rpm creating an almost flat torque curve across this wide rev range. This translates into a whole lot of power readily available during most driving conditions. Now that inspires.

The M3 Coupe is expected to go on sale in Germany September of this year, with the sedan, touring and convertible following later. This is the first time in BMW's history that the M3 will be made available in all 3 Series variants.
Stay tuned for more details and photos. Big hat tip to M3post.com (http://www.m3post.com/) for the radical CGI's

Lots of bhp and not a lot of torque. It's interesting, and much more sophisticated than the LS1 replacement in the older M3s. I'd be interested to see cost and the performance numbers. Good post Blackout. :)

Good post Blackout. :)That's the one thing I've noticed from BMW as of late (mostly the M series) that they produce some nice horsepower but the torque is lacking. But they say that the torque curve is very nice so hopefully it's not as bad as we are thinking

295ft-lbs torque...

lmao.

Torque 400 Nm/295 ft-lb @ 8,300 rpm

Did I seriously read that? Hey, here's a question: What do a 2008 BMW M3 and a 1990 Cadillac Brougham have in common? 295 ft. lbs. What do they have different? 6,300 rpms! :histeric:

Now that inspires.Weren't we saying the same thing about a year ago when we saw the torque numbers for the M5/6 as well? But when you also look at BMW's history the M series was never meant to be the fastest cars out there they are more worried about the handling ability of the car more so then how fast it goes through the 1/4

BMW fans love how you need to rev the engine to keep it in the "sweet spot". It's a completely different driving experience from a Cadillac (or most typically "american" cars for that matter).

And the bimmer-owner's mantra has always been:
I would have had you in the twisties! :D


...and most of the time they're right. :p

Isn't 8300 rpm a little excessive? I mean, to me, 5000 rpm sounds fine for peak torque, but when you have to rev the piss out of an engine to get it to make decent power, I just don't define that as fun. Make it handle like a BMW but give it the grunt of a pushrod motor. I'd be all over that.

BMW M3 people aren't looking for low end grunt.. an awful lot of these cars are tracked. Right now I'm at my shop... there's 5 cars here (We only work on BMWs), 3 are M3s.. 2 E36s (95 and 98) and an E46 (02). All are getting work done to them to get them ready for upcoming track events.

An engine that produces its' power up high is what you want for a track car... I do about 8 track events a year with my M5 or M3.. the cars never see under, say, 4,000 or so on the track unless I am starting out in first to drive onto the track or in the paddock.

Oooooh, impressive! It's getting pretty typical to see BMW's M-division's motors with loads of hp, but not much torque. For example, isn't the new M5 V-10 500hp and around 395 lb/ft? That seems pretty typical of high revving DOHC engines nowadays, VTEC's, M, Northstar, etc etc. BMW is at the top of the automaker's game once again!


Brian, I bet our Caddys could take this new M3....out of the hole! hahaha! I'm not sure about yours, but my torque peaks at 3000 rpm, and it's not much less overall torque than the M3's new V8, 275lb/ft v. 295 lb/ft.

My STS runs the 1/4 in 14.8 and on the same day a friend of a friends year old M3 was running consistent 14.3s. My friends RWD Mustang with the same BHP ads the M3 was running 13.8s

It was a slippery day at the track, but the point is that torque helps a lot on the strip (as does getting the power down) and the same applies on the road. If my Caddy was RWD I'd be confident about going up against an M3 from a stop as I'm sure there's a good 4 tenths being lost due to my FWD.


A lot of people do track M3's, for which they are very good.
But I don't believe the percentage of owners who do that is in the majority.

Most hig hrevving, weak botom ended cars are used as road cars and for me it's not a satisfying experience. I prefer grunt.

Kudos to BMW for getting that much power out of that sized engine although the characteristics that gives it mean it is not for me.
