The new Bugatti Veyron maybe slightly faster in a straight line and finally takes the top speed record that the Mclaren F1 held for almost 10 years but this is still the best overall performing production car in the world and in my opinion the closest thing to a perfect supercar.  It's 3.1 second 0-60 and top speed of 240MPH should be fast enough for anyone in the world.  The Mclaren F1 GTR won leMans in 1995 and Mclaren produced a series of 5 F1 LMs to commemerate the 5 GTRs that raced that year placing 1,3,4,5, and 13.  Horsepower for the LM was upped to 680 HP and was capable of doing 0-100-0 in 828.4 feet in only 11.5 seconds!  Thats about an averaged size residential block.
