MW has officially announced that the first time since 1999, BMW will offer a four-cylinder engine in the U.S. This new engine will be a 2.0-liter, turbocharged inline-four.

The new engine is based on BMWs turbocharged inline-six found across its model line under the 35i badge. The smaller four is rated at 240 horsepower at 5000 rpm and 260 pound-feet coming as early as 1250 rpm, offering more power and 30 percent more torque that the 3.0-liter inline-six it is replacing. It is also lighter and more compact than the outgoing six, thanks to an all-aluminum crankcase.One twin-scroll turbo forces induction into the little four-banger and allows for low exhaust back pressure at lower rpms, and BMW claims that this setup will help to eliminate turbo lag.

As we have previously reported, the new engine will most likely be seen first this fall in the Z4 roadster, and we can guess that most if not all of BMWs 28i models with the old inline-six will probably receive the turbo-four in its place going forward. We hope that the turbocharger will help to make up for lost displacement in terms of power output, but were also looking forward to potential gains realized at the pump. BMW has yet to dish any estimated EPA mpg figures; however, in the Z4, the 3.0-liter six is rated at 18/28 city/highway mpg for both the automatic and manual transmissions. We expect the new, smaller engine to easily top those numbers.

BMW promises further application and timing information for the U.S.-spec four-cylinder to emerge at a later date. Until then, stay with Automobile Magazine/ Motor Trend for the latest news on BMWs new four-banger.

Looks like the good ol' I6 is being phased out :eek: Although I can see this new turbo I4 being a monster in the tuning crowd.

now, if we could just get the 2 litre turbo diesel, all would be well in the world

The new encrypted cpu lockout processors will not allow even the best code hacker/tuner to tune these motors anytime soon :(

240hp is pretty solid for an engine that will both save fuel and weight, I can see it being very popular in the 1series cars!

more torque, more power, better mileage, and lighter. good bye 328. wonder what the 3 series will be called with this new motor.

5000rpm HP peak - if the curve is what that (as well as the 1250 torque peak) suggests, this motor is much better suited to automatic trans daily driving than high performance self-rowing. I'll wait to see dyno curves and drive the thing, but that doesn't bode well at all IMO.

On the flipside, if peaks were above 6k it would have a shitload of turbo lag. Also, I wouldn't doubt that the vast majority of these are going to be infront of an automatic anyway.

Not necessarily, the 2.0L VW/Audi TFSI motor holds its peak HP from 5300-6000 and still has a 1500rpm torque peak. Again it's all speculation, but I'll be sad if this turns out to be a low-rev traffic commuter instead of a fun traditional BMW powerplant. Kind of like the M52TU E46s, BMW quickly came back with more reasonable high-RPM behaviour with the M54 family.
