The folks at the beloved Bruichladdich Scotch distillery on Islay just powered a racecar from 0-60 in 3.5 seconds on a tank full of of its X4 Scotch, billed as the most alcoholic single malt ever made. The car, a British-made Radical SR4 (above), was driven by Top Gear's James May and wine expert Oz Clarke for a segment on their upcoming BBC series Oz and James' Great British Adventure. The clear 180-proof quadruple-distilled spirit, which required no engine modification, produced 200 bhp, only 5 less than ordinary gasoline - but at about $200 a gallon it's a pretty pricey biofuel. A lower proof version of the X4 will go on sale (for drinking, not driving) in the fall. You can see a video of the run here.
