BMW has long hinted at the return of four-cylinder engines to the U.S. market, but has been rather quiet about exactly which four-pots might be headed our way. However, BMW has broken the silence, revealing that four-cylinder diesels will be part of the German automaker’s U.S. plans.
Speaking with Edmunds, Tom Baloga, vice president of engineering for BMW of North America, revealed that BMW is planning to release four-cylinder diesel technology in the U.S. sometime next decade. The diesel four-cylinder will likely first surface in the 3-Series, but could eventually spread to the X3 and X5, and possibly even the 5-Series.
In order to pass as an adequate 5-Series engine, look for the diesel four-cylinder to produce similar performance to BMW’s current range of turbocharged six-cylinder engines. “Our four-cylinder diesel will be so good that people will readily accept it as a replacement for six-cylinders,” Baloga said. “The target is to produce enough horsepower to be comparable [in performance] to our N54/N55 six-cylinder turbos.”
BMW’s U.S. four-cylinder diesel will like be based on the 2.0 L unit that recently launched in the Euro-spec 320d. The 320d is capable of returning nearly 60mpg.
Although BMW’s four-cylinder diesels promise to be the automaker’s most frugal offerings, don’t expect a pricing scheme to match. Diesel will continue to command a premium in the BMW lineup, as seen by the 335d.

GM should buy its diesel engines, necessary to meet CAFE targets, that they were ineffective in stopping, for its vehicles.

GO BMW…. i say bring two versions of the 120d / 320d / 520d…
A) standard single turbo 177hp version starting equivalent in price to the current standard 128i / 328i / 528i
and
B) the uprated performance twin turbo 204hp / 295 lb-ft version starting somewhere between the 28i and the 35i / 35d models
this way just like the gasoline engine model lineup there will be and entry, mid-level, and higher model [excluding ///M3 and ///M5 models ]

i forgot that the article suggests that there will be X3 and X5 20d x-drive models as well… but same goes for those as far as my opinion goes

Yes, NMOFGM, GM sure did have great diesels back in the 80’s! They really also beat the competion with their well executed V-8-6-4 Caddy’s. Definitely looking forward to this engine.

LLN,
is 60 mpg an imperial gallon rating or U.S. gallon?
if its U.S. gallon, than this thing kills the prius, if not, it still kills the prius.

I think LLN recycling numbers from UK, which means imperial gallons. Actually, they are a bit optimistic in UK when measuring mileage, just like in US few years back. But even 15% lower mileage (50 mpg) would prove to be the most fuel efficient car on US road. And those numbers are “combined” mileage.

I highly doubt that BMW will be able to output “comparable level of performance to a 6 cylinder turbo” out of a 2L diesel. Torque-wise, no question that won’t be too hard, but in terms of acceleration figures and horsepower, no way, Jose…
If their benchmark is for the car to “feel” like the x35i engine, that shouldn’t be too hard as it has 300lb/ft of torque, something a 2l diesel can do without much trouble.

Interesting concept… incredible mileage and it won’t handle like a brick riding on four marshmallows.
Naw… it’ll never catch on.

This is Great I hope diesel engines finally catch on in America I would love to see a Twin Turbo Cumminings Viper. Dodge Trucks diesels are running 10 sec 1/4 Mile times !

The Government of Canada brought a 120d 5-door to the Toronto Car Show a few years ago as part of their alternative fuels display and suggested it would cost about Cdn$32K. I was ready to sign up right there and then but also BMW said no.
Bring the updated version to me now please BMW.

if it gets 60 mpg and costs 45k, it doesn’t kill the prius ;P

Freakin awesome, drop it in the U.S. 1-series and give us the hatchback version too. Price it under under the A3 TDI and you’ll have quite a few takers.

Let’s just hope they can get the buying public to go for it. I haven’t seen many 3-series or 5-series diesels on the road.
Though I did get a chance to test-drive a X5 with the diesel… holy smokes, talk about a wall of torque that doesn’t let up.

so if they plan on making the four pot match their I6, doesn’t that mean if you get a AWD model your basically getting a german lancer evo X? not that there is anything wrong with that

Lefty you are correct, it will kill Volt (at least for me it will).

Nah… Volt will still sell.
No matter the price, the ability to drive to work and back each day using zero gasoline is a huge incentive for a lot of people. My commute is 12 miles each way… and that is 90% of the driving I do. If I need to stop in a store, I drive right by plenty of them on the way home.
I would buy a Volt in a heartbeat if I could afford it.

If my commute was 12 miles and not on highway I would use bike (as a bicycle) at least during decent weather. 100% ROI.

yeah, i know a couple of people who bike 20 miles to work each day Raineman, one of them on a single speed mountain bike. You don’t need a car at all, buy a bike for 300 bucks that gets infinite miles per gallon!

@aexcorp , bmw already has diesel engines with more than 100hp/liter, the 4 cylinder, 2 liter 123d with 204 hp is in V6 territory.

atmos: yeah except… evo X’s have much more advanced AWD/stability control/yaw control systems and although they have turbo inline-fours, umm… they are not turbodiesels !
good though though…
