Very fast. Very old. Very new. That's the short version of the vehicles in the image above. On the left, there's the JCB Dieselmax, which broke the diesel land speed record at the Bonneville Salt Flats last week. In the middle, there's a 1918 Detroit electric vehicle for sale on eBay. And on the left, we've got the new motorcycle/car Carver, which already gets 43 mpg and a hybrid/flexible fuel version is on the way. All this and more at AutoblogGreen.
