1 series came out in 2004, and is based on the E46 platform, which is even older. It just came to North America in 2007, and got the coupe body style. The standard 7 year cycle is up in 2011, which is why this is the last year for it.

When the Mini was redesigned for the 2007 model year (R56 replaced R50), there were lots of changes. It was more than an LCI, as there was a new platform. The turbo was mentioned above, but I think the use of the Prince engine (joint BMW/Peugeot/Citroen) instead of the earlier Tritec engine (Chrysler Brazil) was a pretty significant change as well. The R50 was designed by Rover as much as by BMW. The R56 is a product of BMW engineering. They just kept a lot of the styling cues.
