The Lamborghini's take first place on this round, above 300 Km/h nearly nothing comes close to the Diablo GT's 345 Km/h, the only car that nears it is the Ferrari 550 Maranello with 320 Km/h.. In earlier days things were different, the McLaren F1 beat just about everybody with a stunning 386 Km/h, while the fastest car ever tested in Europe was the Bugatti EB110 SuperSport with 351 Km/h. But during the MY 2000, Lamborghini had the fastest production car around with the Diablo 6.0's 335 Km/h, note that Top Gear tested a 6-Liter VT with the optional final drive ratio's on the Nardo circuit and reached a verified top speed of 359 Km/h.
