Huw over at Brickset got a tip about some new promotional sets from Shell and Ferrari. He did all the virtual leg work and has put all the details up for anyone interested, so I'd suggest you check it out. The basic breakdown is these six vehicles will be available at Hong Kong Shell stations for a couple of bucks ($20 HKD) when you buy $50 in gas ($400 HKD) and they should be available worldwide at some time. There's even a seventh set that should be available once the first six have been obtained. I'd expect a similar deal to get them when they are available and I suspect these will be popular with many collectors and tiny turbo fans. We'll keep an eye on this and try to keep you updated as these become available in other regions.
