A worthy successor to the Bugatti Veyron, the Chiron is one of the fastest and most expensive cars on the planet. The Chiron Super Sport 300+ model is arguably the wildest and most extravagant in the range. Equipped with an 8.0-litre 16-cylinder engine rated at 1,577 horsepower, it can reach a top speed of 489 km/h. In fact, Bugatti set a record by becoming the first automaker to top 300 miles per hour.
