As reported on E90post Homepage.

According to BMW U.S. chief Jim O'Donnell, from the 2009 Frankfurt Motorshow which is currently taking place, BMW has approved plans to finally bring a 4-cylinder 3-series to the U.S. BMW lineup. Expect the engines to be equipped with BMW's next generation twin turbos as he also stated that this (pairing twin turbos with the 4-cylinder engines) "is the goal and we will do it."

The decision to finally introduce a 4-cylinder version of the 3er into the U.S. is part of BMW's plans to meet tougher U.S. fuel economy and emissions standards for the next few years -- all auto manufacturers are required raise the gas economy of their entire lineup by 5% a year until year 2016, when a national 35.5mpg standard will be imposed (fleet wide).

The 4-cylinder version 3-series is expected to first be available for sale beginning in the spring of 2012 and will be equipped on the next generation 3-series (F30). Don't count out BMW using the same 4-cylinder engines in future X1 and X3's as well, as those cars currently share engines with the 3-series.

From automotivenews:

FRANKFURT — BMW plans to offer four-cylinder gasoline engines in the United States in an effort to meet stricter fuel economy rules. Introduction of the powerplants, equipped with the automaker’s next-generation twin turbochargers, “is the goal and we will do it,” Jim O’Donnell, CEO of BMW of North America, said today on the sidelines of the Frankfurt auto show. O’Donnell said the engines will allow the automaker to reach U.S. targets before 2015. Under federal guidelines proposed today, automakers will have to improve the fuel economy of their fleets by 5 percent annually before a national standard of 35.5 mpg takes effect in the 2016 model year. BMW will add a four-cylinder variant for its next 3 series in the United States by spring 2012, O’Donnell said. The automaker already equips its European 3 series with four-cylinder gasoline and diesel engines. BMW also is considering adding four-cylinder gasoline engines to its X1 and X3 crossovers and 1-series model in the United States. In Europe, the X1 will be available with a four-cylinder, twin-turbo diesel engine when it launches this fall. The X3 and 1 series also are offered with four-cylinder gasoline and diesel engines in Europe. “We see potentially a significant market that could get to 100,000 four-cylinder engines” in the United States, O’Donnell said.

Ick, 4 cylinders...

[F32Fleet]

I really don't undstand how BMW is going to obtain significant fuel savings on a turbo'd 4cyl gasoline vs a simliar performing NA 6 cyl engine. It's not like BMW cars are loosing weight either. Maybe they'll be diesel??

My old 4cyl 1.8T gas mileage destroys my N52 I6 fuel economy. 32 to 24/25.
4 cylinders require less fuel than 6. Pretty simple..

[maswastage]

I've always been biased against 4 cylinders, just because every one I've ever driven has always been rough and unrefined. A 4 cylinder turbodiesel wouldn't be bad, though I'll always prefer a smooth inline 6.

They'd better fix their HPFP issue first . . . .

as far as i know of the 4bangers haven't had any major issues so far

The 4cyl diesels are awesome engines and respond quickly and smoothly, but whenever i step in our 3l diesel X5 i just get taken in by the sound & force of that but i'm sure it'll be a welcome addition for many

[ctgazer]

hmmm keepin my eye on this...might be interesting

[Joeb427]

Many thought the new N55 would be in a '12 3 Series model.
Now it's a TT 4 cyl.Surprise,surprise.
I'd rather have the N55.

More space for bigger turbo kit upgrade

if an sti could have a 4 banger and still be as fast as it is.. why not bmw?

[Derek Zoolander]

STi gets shitty fuel economy though because it's tuned for higher boost/performance.

[EmPower]

This will surely replace the 328i in the model lineup. So they way I see it, the 3 series will have the token diesel + a 4 bangerTT start of the range, a 6 bangerTT as the middle of the range and the M3 with a 6 bangerTT. Maybe if they are smarter, they will get a low capacity deisel to compliment the 335d

I have an e46 318d and yes it's unrefined , but the fuel economy is great 5,4 l/100km

[roadkillrob]

Audi/VW 2.0T - decent performance and great fuel economy - if they pull it off as well as VW did with that engine, then no compaints!

[Imola.ZHP]

More choices are always a good thing for consumers...

I prefer a smooth I6, but can understand the market place for 4cyl bimmers.

Since when does BMW only offer one engine? Never, there will be a higher output 6 cylinder, the N55 more than likely with a few additional tweaks.

The 4 cylinder will replace the N52- the N52 will have served a full generation by then.

What is not stated here is that the reason for this shift is all about efficiency and emissions. Times are changing and some people better realize that.

They already have it, the 320d. But it is not coming to North America.

57.4 mpg.

The important thing is that BMW of North America is protecting the brand by keeping that European crap out of the American showrooms.

I've read the new N55 will not be installed in a 3 Series.How true that is?I don't know.
You're probably right,though.There will be a 3 Series with some sort of 6 cyl.
