Want to go really, really, really fast? Like, a regional jet on approach? Engage the Veyron’s top speed mode with a special key and the car lowers itself for a 253-mph run. Beyond 233 mph, the car’s computers decide if conditions are right for an attempt. The thrilling numbers to that point? A 0-60 mph time of 2.7 seconds, a braking time from 60 mph in less than that, and a 5-second 0-60-0 mph elapsed time.
