The next 1- and 3-Series cars from BMW, as well as the Z2 roadster, are rumored to be getting a new range of turbocharged three- and four-cylinder gasoline engines as part of BMW's push to cut emissions and fuel consumption. Of the five powerplants reportedly in development, three are 1.35-liter three-cylinder motors developing between 163 hp and 241 hp, with the two 1.8-liter 4-cylinder engines putting out 273 hp and 321 hp, respectively. Sky Motoring says that the four-pots will be reserved for "more upmarket models."

While a 3-Series with a 3-cylinder engine has a certain poetry, it does give one pause. If Sky Motoring's numbers are correct, however, the top end 1.35-liter motor would put out 11 more horsepower than the current 3.0-liter in the 328i. That's a lot of power for such little displacement, and with brand perception issues in the U.S., who knows if we would even get the engines - after all, we don't get any of Mercedes' CGI mills. From where we sit, though, the smaller, lighter engine with its commensurately fewer moving parts could also help bring the sticker price of the 1-Series down - one of the major factors that has prevented it from gaining traction in stateside showrooms.

In any case, the new BMW engines are said to be at least two years away, so we look forward to getting more clarifying information in the meantime. Hat tip to Owen!

Wow. Odd in several ways. I'd have though BMW would have used smaller displacement 4-cylinders instead of a 3-pot.

I mean, if it's an image thing, a three is worse than a four.

If they want to improve CAFE, they should shave some of the lard off of the 5 and the 7.

163hp out of a 1.35L 3cyl? Thats really impressive. Consider the Metro had a 1.0L 3 and it made a whole 55hp.

Don't soil your panties just yet, they say two to three years at least. I'm still waiting for the Volt and Lord knows the Camaro just got here.

Think I'll watch and wait.

Maybe they'll be worth it, too.

I thought 100 hp/l was impressive, 178 hp/l is insane.

maybe some super/turbo charging...HCCI too? but yes. put that much power in a.... miata sized car... that could be very fun!
