Currently, the fastest production car in the world is the Bugatti Veyron. Not only the fastest, but the most expensive at over $1.4 million dollars. This car boasts about 1000 horsepower and will do 0 to 60 in about 2 and a half seconds. Wow! It will do 0 to 125 in a little over 7 seconds. At a top speed of 253 mph, it would run out of gas in 12 minutes. This is all because of it's kick a** W16 quad turbo engine. What Bugatti, which is actually owned by Volkswagon, did to get all that horsepower, was basically join two twin turbo V8 engines together to form the W configuration.
I want one!
