Sorry Bugatti. The dark-beer company that's been tracking the best, fastest and biggest — ever since the company's managing director, Sir Hugh Beaver first argued over which was the fastest game bird in Europe — Guinness World Records has verified the SSC Ultimate Aero as the "Fastest Production Car." As we reported recently, Driver Chuck Bigelow, 71, took SSC's Ultimate Aero for two passes on highway 221 in Washington state, the first at 257.45 mph, the second at 254.92 mph, for an official record speed of 256.19 mph. That supersedes the Bugatti Veyron's still-unofficial time of 254 mph, as noted by Car and Driver and Top Gear's James May. Will Bugatti respond, or will the time stand until Koenigsegg or McLaren get serious about taking a run at 270 with a new pair of cars? Watch for an arms race on a flat stretch of road near (or not so near) you. [Source: Shelby SuperCars]
