After setting a record in the G/Blown Fuel Altered class last October with a 212.684 mph run in a Saturn Ion Red Line, GM headed back to the Bonny Flats recently to take the new Cobalt SS through some speed trials. Besides wanting to obliterate its own records, GM also aimed to test and promote its four cylinder Ecotec engines. An 850-hp example was employed by the Cobalt racer in attaining 243.127 mph. Unfortunately this number couldn't be counted as a record since the Cobalt wasn't on sale at the time, but GM vows that it will be back to make it official. Two other Ecotec-powered vehicles also ran at the event: a So-Cal Speed Shop-prepped 1934 Ford roadster, which set a roadster record at 193 mph and then proceeded to throw a rod trying to get over 200 mph, and a dart-like streamliner that easily eclipsed 300 mph.
