BMW will revive the Z8 roadster, slotting it above the 650Ci convertible in the $90,000-to-$125,000 price range. It will be powered by a 400-plus-hp turbo version of BMW's 4.4-liter V-8 mated to a new dual-clutch gearbox, but other engines--larger and smaller--may find their way under the hood as well. We'll see it in 2010.
