Was reading Road and Track page 20 I think, and it stated that the new M3 would be a inline 6 with twin scroll turbos, but no data on Hp/Trq etc...

Things could get real interesting...

Anybody else heard this.

I've heard about this as well from one of my buddy's who works at BMW.

I think one of the reason being is because Audi is changing their S4 4.2L V8 setup to go 6 cylinder twin turbo. I actually read that off of one of the magazines I subscribed to.

Audi just changed the S4 to a 3.0 V6 Supercharged engine.....are they going to be changing again?

As we have seen, the N54 with properly sized turbos and supporting mods is good for 500+ WHP.

With stronger internals and (hopefully) shorter stroke, displacement goes up as does redline rpms.

...just think 500 HP N54++ with a redline of 8k.

I'm sure BMW has the S54 castings laying around... somewhere. S54 block, N54 head, properly sized tubo/turbos, game over.

IMO, if BMW decides to go with a 6 it will be a straight six. They'd get blasted for going V6. Too far from their heritage. If they go straight six, they'll go twin turbo as the headers for a single turbo setup would be on the long side which would reduce responsiveness, a serious no no on an M car. So, I'm thinking twin VGT turbos ala Porsche 911 Turbo and an air to water intercooler to reduce the charge piping to further aid in responsiveness.

Probably wrong forum btw...

There´s been a lot written in the europeen press about it, but it´ll be with a v6 engine

[nukezero]

twin turbo inline 6 are the way to go.

iconic and legendary cars have all been inline 6 twin turbos for its efficiency and performance and weight advantages.

better check your facts again.

[zsapphire7]

i wonder how throttle response will be however...

[samchoi604]

hpfp failures to be continued...?

[cstavaru]

It can't have twin-scroll turbos because it is not mechanically possible. It can either have one big twin-scroll (less likely) or two single-scrolls. My guess is 3.4-3.6l twin-turbo inline-6 with 440-450hp.

My guess is a 3.3 biturbo. Same engine as the newest X M6/M5 minus 2 cylinders .

I always thought that 911s had boxer engines..

[enrita]

yes porsche is definetely boxer engine. Otherwise you could use the back seat space to fit an inline 6 haha

Watch out M3 ... Here comes the Audi RS5 450hp or more this summer ?

[fast4door]

4.4-liter, 32-valve M TwinPower Turbo V-8 engine with High Precision Direct Injection, cylinder-bank comprehensive manifold (CCM), and 4 overhead camshafts

I thought the new M3 would have this engine, which is currently in the X5M and X6M..currently rated at 555hp..would be nice. I was going to trade up to the M3 when it came out, but now not so sure if it will be a inline six

[GreenPlease]

They could shoe-horn in the V8, leaving them with only one M engine (cheap from their standpoint) but you have to think that ///M wants to start paring weight from the car hence the move back to a six cylinder engine.

For the record, isnt the 911 (99X cars) a flat six?

Edit: Should have read further down the post count before posting...

I don't get how much closer Audi can put the RS5 to the the R8 V10 (518 bhp/391 lb/ft tq) and still keep it competitive with the M3 pricing. Why would Audi sell an RS5 with near or at 500 hp for $80,000 and then the R8 with the aforementioned stats for $146,000. Granted, the R8 looks badass but the numbers just don't add up for a cheap RS5.
