No diesel for USA 1er Coupe/Cabrio . It is nothing to do with state compliance, More image and economics in which it would not be advisable to import the car to the USA. It is an engine the car is more focusing on but is petrol powered not diesel powered.

Well 2K, there's your answer. Just to throw a wrench into the works, and continue the speculation (even tho it looks like Scott has settled the matter),
how 'bout an e88 platform and rubber-suit to disguise testing for this...

BMW Z2
Actually, it could be going both ways, ie, Scott is right...a new engine being tested (and my speculation) in a very disguised Z2.
Just kidding but it's fun to think about and maybe provoke someone to add to the scant info we have on a Z2 or if it's even in the pipe anymore.

Hey Scott, do you know yet if its an ''all new motor'' or did BMW possibly crank the boost on an already perfect motor? Its a bit interesting that they were in a conv and not a coupe. Its pretty confusing.

Brookside, your nuts!! That would be some pretty heavy camou.

2lt turbo??

FYI...some people just can't wait for a motor like this from BMW (including myself).

A 240HP 2L Turbo has been rumored for sometime now.

I just sold the 135i. Turbo is not my thing. There is always throttle lag. I rather drive my 130i than the 135i. 130i has less power then the 135i but the engine of 130i sings on high revs. I really miss that on turbo engine. 130i lacks grunt on low revs. But with a better throttle response i easily forget that.

I really think you should go for an engine swap... put the S54 in that cute little bay ;-)

So there was noticeable lag, was your 135i tuned?

Today turbo lag is inevitable on a turbo engine, the 35i is great in this respect but the technique is not yet completely lag-free... so if you are a N/A purist there is simply no turbo alternative that will do.
