According to Autoblog, via Automobile Magazine and via a live tweet (yes, we know, lots of “sources”), BMW is planning to bring a four-cylinder engine to the Z4 family in the North American market.

The Twitter rumor reported by Automobile Magazine mentions BMW ditching the naturally aspirated 3.0-liter inline-six in the base Z4 roadster in favor of a turbocharged four-cylinder powerplant. If the rumor turns out true, the Z4 sDrive30i will be featuring the first four-cylinder engine available in the United States.

BMW has been contemplating with the idea of offering a four-cylinder powerplant in the US, but expectations were that the unit will be found in the X1 or future 1 Series models. The engine in the Z4 will output at least 200 horsepower and 220 lb-ft of torque.

Detroit Rumor: BMW Z4 to get a four cylinder engine in the USClearly details are slim at the moment, thanks to the 140-characters limit imposed by Twitter, but we expect to learn more through an official article published by the respectable magazine.

Big news, yes, but it doesn’t come as much of a surprise since BMW has long flirted with the idea of using turbocharged four-pot mills in its base models like the Z4 sDrive30i and even the 328i.

    Something doesn’t add up here. Yes, yes, we all know BMW will bring 4 cyl’s back to the US market. However, the E89 seems to be an unlikely candidate. Questions that need to be addressed include but are not limited to:

    1. If BMW had intended to put a 4 cyl in the E89 then, they wouldn’t have taken the whole car ‘upmarket’ from the E85 — which never had a 4 cyl variant for the US market.

    2. Profits? Putting a 4 cyl in a German-built car for the US market would exacerbate AG’s EUR/USD situation.

    3. Consistency across product lineup? According to this AUTOCAR blurb, http://www.autocar.co.uk/News/NewsArticle/AllCars/254736/ a turbo’d 4 cyl doesn’t have enough power for an E82 “tii”.

    Well, personally, it’s not that the engine doesn’t have enough power, it’s that the car is probably too heavy for a 4 cyl. If so, why would it be any better of a package in an E89?

    4. Timing. Look at the timing of this tweet.

    5. Market dynamics in the US. Sales for premium German 2-seaters (Z3-Z4, Boxster/Cayman, SLK & TT), peaked in 2000. Sales during 2010 were off over 80% from peak! BMW is probably content with their #1 market share in US @ ~35% and, allegedly, ~56% share worldwide. Is there truly a big enough niche for a 4 cyl Z4?

    Consequently,

    I suspect that the focus of this speculation is actually the presumed upcoming “Z2″, not the current Z4.

    I’ve got to agree with bob, this makes no sense. This is a tweet, after all, so it has very little validity. A smaller MX-5 fighter (Z2) would be a fine home for a turbo four, but not in the Z4, it would be too heavy, and inconsistent with the Z4′s image. If anything, the 4.4 liter V8 should be made an option.

    First in the 1er and 3er , then X3 , X1 , and so on. You will know more by the summer regarding the engine.
