Spy Video Of 2010 BMW Z4 Testing in the Arctic CircleAbout the Video: We've already seen the 2010 BMW Z4 on the streets of Munich and on the Nürburgring, but now we've managed to snag some footage of the upcoming roadster during final cold-weather testing in the Arctic Circle. From low-speed testing on the city streets to higher-speed action on a frozen lake, the engineers at BMW are throwing everything they have at the next-generation 2010 BMW Z4.
Like previous prototypes of the 2010 BMW Z4 that we've seen, these cold-weather test mules appear to have a traditional soft top. Don't believe it, as we suspect it's nothing but clever camouflage designed to hide the fact that the 2010 BMW Z4 is switching to a folding hardtop.
