Press Release:

Following recent unveiling at the New York Motorshow.

Media Information 20 April 2011

BMW Z4 at the New York Motor Show (April 20/21) with new 2-litre TwinPowerTurbo engine for the first time.

Munich. With its athletic design, agile handling and powerful engine, the BMW Z4 has achieved outstanding success in the class of premium roadsters, having been the worldwide segment leader in 2009 and 2010. Towards the end of the year, the BMW Z4 is to feature another technological highlight: a completely newly developed 2-litre engine with TwinPower Turbo technology and an output of 176 kW/240 bhp. Its name is BMW Z4sDrive28i.

Thanks to TwinPower Turbo technology, the new supercharged 4-cylinder petrol engine with all-aluminium crankcase, already available in the BMW X1 xDrive28i, provides increased torque, improved performance and much reduced fuel consumption and emission levels as compared to the existing 6-cylinder induction engine model BMW Z4 sDrive30. The absolute figures, including those for the driving performance of the new BMW Roadster, are expected to be finalised mid-year.

This newly developed engine in the BMW Z4 sDrive 28i uses the globally unique BMW TwinPower Turbo technology. In other words it is fitted with High Precision Injection as well as a turbocharger powered via two exhaust ducts. Other elements of this progressive engine package include the variable camshaft control system double VANOS and the fully variable valve control system VALVETRONIC.
The new 2-litre petrol engine with BMW TwinPower Turbo technology in the BMW Z4 sDrive28i thus sets a further milestone in the BMW EfficientDynamics strategy.
 
Thanks for that :thumbsup:

Can you have a word with your press people though...

:?

I assume "supercharged" is being used as a superlative, but given it's a turbo engine they surely could do better?

Anyway... while you're here... will this be a facelift model? What are the changes for the facelift?

ADD: actually, on the 28i, is this a lot lighter than the 30i?
 
Hi PawnSacrifice,
This is as much as I know about the model for the moment, I'll post up more information as and when I receive it.
Hopefully I can answer all your questions.

Cool, thanks... as much as I love the BMW I6 engines, I'm all for lighter nimbler cars, and if this engine delivers it could be a very interesting proposition indeed - with the Audi TT a lot of testers prefer the 2.0 because of the way it drives compared to the bigger engined models.

As always, I'm sure there will be more interest on here for any hint of a full on M model :)

Thanks.
 
Ah, this is the bit I was interested in..

We expect that BMW will phase out all naturally aspirated inline-6 models, and it remains to seen if any model BMW, even the M3, will remain naturally aspirated. It’s not a bad thing, as the smaller four makes almost as much power as the one it replaces—240 versus 255 bhp. In the process, nearly 45 lb are taken off the front axle, which means the weight balance of the car has shifted rearward—both changes being good for this little roadster’s handling.

Worth a quick read, it is a US article so ignore the fact that BMW sells vast quantities of 4cyl engines around the world and this is overlooked! I know many will fundamentally disagree with the 4cyl turbo, but it sounds like it could be a good car.
 
i certainly wouldnt mind it.

A lot of euro manufacturers now have boosted engines with small displacement (Peugot RCZ and Cooper S share the same 1.6) and they are a lot of fun. Also they are much torquier and dont suffer the same turbo lag that the old scoobies boxer engines had.

I guess this is a typo. A difference of 45 kg sounds more realistic.
For example the E85 6 cyl N52 3.0 vs. 4 cyl N46 B20 is almost 100Kg.
