Sunswift IV, world's fastest solar-powered racer, leaves GM Sunraycer in its dust

The Sunswift IV (aka IVy) might look like a mobile dinner table, but it's actually the world's fastest solar-powered vehicle. The table-top on wheels got the official nod from the Guinness Book of World Records last week, for hitting a top speed of 88km/h (about 55 mph) -- nearly 10 km/h faster than the previous record-holder, the GM Sunraycer, which bears a striking resemblance to a disembodied Android monster. IVy, designed by Sunswift, a student-run non-profit at the University of New South Wales, reached its top speed using 1050 watts, about 400 watts less than the Sunraycer, and performed its record-smashing run without the 25kg battery it's usually packing. Faster runs have been clocked, including by IVy, but Guinness has not been on hand for confirmation.
