Supercar fans may want to sit down before reading about the development of a 280 mph Bugatti Veyron. Rumors regarding an upgraded Veyron have recently gained steam. A more powerful version of the record-setting supercar is said to be in development, with a target release date of early 2014. The new Veyron would have somewhere in the neighborhood of 1,500 horsepower and would possibly be able to bit 280 mph.
These numbers are significant as the Veyron is a street-legal supercar, meaning that, theoretically, you could do 280 mph on the way to Walmart. That being said, you aren't likely to see the upgrade supercar on the road to a super store. Price estimates for the 280 mph Bugatti Veyron are coming in at around $7 million.
