Fact or Fiction: X1 Overboost from the factory?
Saw this on a couple magazine reviews and I'm wondering if US models have this feature, and if it really only applies to the AWD versions:

Here is a BMW official press release that mentions the overboost rating too (see tech specs and horsepower/torque numbers).
I notice this document is for the Canadian market. Does that mean US models didn't have this feature enabled? [EDIT: I just went to BMW USA and BMW Canada's website and the technical specs for the xDrive 28i make no mention of the overboost ratings, the US site lists 240 hp and 260 lb-ft, and the Canada site lists 241 and 258, at least for the 2015 models. If you check bmw.com, it actually does show an overboost rating in the tech specs for the Z4 and 1M!]

UPDATE: I submitted an inquiry on BMW's website after I started this thread, and a BMW Genius was assigned to my case. They spent several weeks researching my question about the overboost feature (different departments were just as confused as we were), until finally their North American specialist weighed in with this information:
The BMW Genius did not seem to know if the overboost feature required hardware or software changes (or both), so I don't know if it's something we can simply (or safely) "unlock" on our US models. I also don't know if BMW beefed up the components of Canadian models for overboost (better half-shafts, transmission, etc.) to accommodate the additional power. A quick comparison of parts diagrams or phone call to a BMW tuner in both US and Canadian markets might be able to confirm or deny if there are any programming differences between X1s in these markets. I asked if there was any possibility that the overboost information was simply inaccurate or incorrect, and they said no, it's correct and not a typographical error or mistake.

thanks for your research.
Is this a new for 2014 thing? Perhaps somebody could run a comparison of a Canadian vs US VIN. It doesn't really make sense to me that this would be a Canada only feature.. Canada's typically a much smaller market. |

What boggles me, it's in Canadian cars but not US spec? Kinda seems weird unless it has something to do with Cali N26 engine emissions.
