Four cylinders, 400 Nm: BMW's new turbo diesel
It's nothing new that torque addicted, diesel junkies abroad get all the cool stuff, and now this. BMW just released details on its new 2.0-liter, variable twin turbo diesel engine that is making 204 HP and almost 300 ft.-lbs. of torque. The two-stage turbo system, initially introduced on the 535d, all but eliminates any amount of lag by utilizing a smaller turbo at low engine speeds and a larger snail higher up in the rev range. The result: 147 ft.-lbs. at 1200 RPM and 295 ft.-lbs. of twist at 2000 RPM. Coupled with a lighter aluminum engine block, BMW maintains that a significant increase in fuel efficiency over the outgoing model has been realized.We liked the 535d when we took it for a spin in LA, and we're sure that this new engine, whether in a 1-series or a 3-series, will be just as entertaining.

100 horsepower/liter from a diesel?!?! Is the 2.0-liter figure correct?
Looking at the chart, that torque curve is much higher and broader than that of most diesels.

Let me put that in the form of a question:
Has there been a production diesel that puts out over 100 horsepower per liter? Or is this the first?

Wow. Put that in the Canadian 3-series... and I'll be at a BMW dealership placing my down payment.

GM claimed to do this in 2004:

Still trying to determine whether this "production" diesel with 112 horsepower/liter and the first diesel applicatin of twin sequential turbos actually made it into production.

PiCASSO,
Same here, I like the 335 but it's a bit too much money for me. On the other hand I think tis engine is amazing, diesel efficiency plus good power!

As far as I can tell, the Opel engine remains just a concept. And BMW claimed that the figure for the 535d engine of 91 horsepower/liter was a production car record. So this would appear to be the first over 100 that people can actually buy.
Looks like GM could have been first, but wasn't.

Forget the 3-series, drop this in a Z-series roadster PLEASE.
I *will* buy one.

I think the title should read 400 Nm not 400 nM

Wow, the torque this engine produce at 1200rpm is already more than the maximum torque my RSX Type S would procduce over its entire rev! And yet this engine produce the same HP. If BMW would put this engine in a car less than 2800lbs, I'll trade it in immediately.

What an impressive little gem! I hope we see more small displacement, turbo powerplants coming to the USA by all makers.

It's not a twin turbo if the turbos are not the same size. Please look up the definition of "twin."

3-series diesel cabrio, PLEASE!!
P.S.
Twin, dual, whatever -- relax.

That's it, with all the winning race cars and high performance cars making great power with turbo diesel I think my next car will be turbo diesel powered.

Rumor has it that this technology will be released in the 2008 Saab 9-3.
When I saw this BMW announcement it immediately made me think of the 200+ hp turbo diesel rumored to appear in 2008 Saab 9-3's
---------
And the diesel.
As mentioned in previous posts, there will be a twin-turbo 4 cylinder diesel made available producing high levels of both torque and horsepower. It's unknown whether this will be offered in the Black Turbo trim, but it will be an offering for the 9-3 in Europe in the new model year.
Back in 2005 at the Frankfurt Motor Show, GM debuted a twin-turbo 1,9l diesel engine as part of the Opel Antara concept. This conceptual engine was quite possibly much like the 400hp conceptual engine in the Aero-X, i.e. a computer modelled engine only.
Now it's a chance of actually coming to life in the MY08 9-3. The Opel concept engine delivered 212hp and around 400Nm of torque.

GM claimed a record with the first concept, but first to production matters much more. I'm concerned about the same happening with the Volt. Decided it was worth a blog entry:

I've always noticed diesels with equivalent horsepower numbers over power their gasoline partners in 0-60 times and with good reason. At 2000 rpm this engine is already producing over 110 horsepower and by 3000 makes 155 horsepower.

What GM diesel?
Last time I checked VMmotori was making larger displacement diesels (3.0ltr+) and Fiat making smaller displacement diesels.
The twin turbo 1.9 was infact the 1.9ltr from a fiat and designed and engineered by fiat but used by GM. THAT DOESN'T MEAN IT BELONGS TO GM.

Well, it's all speculation at this point.
We'll just have to wait and see which car winds up with this type of engine first. A BMW or a Saab.
My guess would be BMW, but I'm not going to count GM out quite yet.

It's very possible that that engine was never actually built, just a concept.
Trollhattansaab has had some very reliable information from inside the factory that the 2008 9-3's will get a similar twin turbo diesel to the Opel concept (at least for European markets). We'll just have to wait and see at this point.

2.0l 4cyl turbo diesel
200hp 4000rpm
410Nm 2000rpm
0-62mph 7.4s
238km/h = 149mph
5.7l/100km = 41mpg US
