The PPX stock “FASTEST” was halted and delisted today after the Ultimate Aero TT, produced by Shelby Supercars, posted an average top speed of 411.76 km/h during speed tests in the Nevada Desert, breaking the Guinness record for “world’s fastest production car,” and thus unseating the Bugatti Veyron from the record-holding position. The Ultimate Aero is powered by a 6.3-liter twin-turbo V8 engine that produces 882 kW of energy at 6,950 RPMs.

This proposition was trading at just POP$49.75 per share when the record was broken, paying out at POP$100 per share. —Megan Miller
