1999 Lamborghini Diablo VT Roadster
The engine lid was changed substantially in order to vent properly when the roof panel was covering it. The roadster also featured revised 17 inch wheels. The air intakes on top/sides were made larger than the coupe Diablos. In 1998 the wheels have been updated to 18 inches, and the engine power raised to 530 HP by adding the variable valve timing system. Top speed specification was raised to 335 km/h (208 mph).
In 1999 the dashboard received a major optical update by Audi, and the pop-up headlights were replaced by fixed headlights, same as for the coupés. This resulted in a better aerodynamic shape and modern optics.
