Looks like the Diesel tax break should be safe for a while
 

The $1,800 IRS tax credit for the X5 diesel will be phased out once BMW has sold over 60,000 eligible hybrid and diesel vehicles.

New Energy Tax Credit for Diesels

I wondered when BMW might hit this limit and the tax credit go away, and then I saw this article:

"BMW doesn't typically break out individual model sales but O'Donnell indicated that since the beginning of 2009, over 2,600 diesel 335ds and X5s have been sold."

Looks like the tax credit should be safe for quite a while.

Nice find, thanks!

But are the 2010s included?

I suspect that BMW NA has to submit paperwork to the government to get formal approval for the 2010's, but since nothing in the powertrain is really changing, it should just be a rubber stamp approval. Since the criteria is the MPG rating, I would guess that they cannot be formally approved for the credit until the models get official EPA MPG ratings assigned.

2600 diesels isn't bad when one considered the limited amount of diesel allocation spots that we're given.
