BMW makes some killer engines in their M variants. Heck the 3L turbo in the 335i is very nice. This one is no different. I applaud them for bringing some F1 technology into production vehicles. And unlike Ferrari the M3-M5 are at a cost some people can afford. I see no reason to compare it to GM's engines. Both are great for what they do. Everyone has their favorites I could say the Viper V10 has more hp and tq than the LS7 but so what. This M3 will run and do it well BMW puts more than just a strong engine into the M cars. This thing will probably take down a 911 or even a C6 on most tracks.

 

I dunno about that.

 

340 TQ out of a naturally aspirated 4.0l engine would be quite some trick! You'd need at least 4.4l with DI to get that. Or 5+ liters for a regular port injected engine.

 

No. It will take neither.

 

I was saying in general, I would rather have a little more balanced TQ to the amount HP that is made. I wasn't really talking about making it out of 4L. You are right about probably needed a good bit more displacement, if it stayed NA.

i wouldnt be surprised if it weighs more the a ls7/ls2.. which is not impressive.. an small torque number.. garbage they are lucky their name is bmw.. if chevy made that they would shot down by a rpg...

 

I like the edgier look, but I'd rather have the last twin-turbo version, with a little work it's hp could almost be doubled...and it was capable of 150+ on the Autobahn.
What's top speed tested on this new version? tho I know the stock ones will be limited to around 150 as well.
(Ofcourse, late '90's Camaro's were capable of that speed as well.)

The amount of tech in these new engines are amazing but, it's like the saying by "Scotty" on "Star Trek".
"...the fancier you make the plumbing, the easier it is to clog up the drain."

There's something to be said about GM trying to keep things simpler and more reliable.

 

Most german cars have 155mph governors. I suspect that this one will be no different.

Oh, and stock F-bodies were doing 150+ in the early 90's. In the late 90's, we broke 160.

 

actaully tta's were hittin 170s in the 80s i think

 

Being capable of overcoming wind resistance with brute power to the point of hitting 150mph is one thing.

Doing it without feeling like at any given moment the whole car is going to shake itself apart or veer off the road, is another.

 

What the heck is going on with the right-hand exhaust assembly??? Looks like a monkey took a hammer to it.

 

So you've driven both at top speed and know this?

I agree. I had an Isuzu Imark RS with a 7500 RPM redline. What a pain! Of course, I presume the M3 would not be thrashy like the Isuzu was. But still, you don't always want to be driving it like it's a racecar.

 

An interesting tid bit I heard; that something like 3,000 / year take delivery in Germany so the can drive them at speed a little while before bringing them home here.

Also, I have had my IROC to almost 140mph, but it was a white knucle affair. B/C of worn suspension parts which I upgraded post haste afterwards with ALL Polyurethane bushed pieces. Haven't tried it again since, b/c the drivetrain is in the middle of a major rebuild/upgrade....

 

I have read the LS7 weighs less then that. Were the weights you gave with a weight block or a dry block? Full accessories? Either way, I knew the Bimmer engine wouldn't way as much as some of the guys on here would have wanted to have you believe.
