Unlike the Diablo VT, the second generation Diablo VT Roadster was produced from 1999 until 2000. As with all Diablos from the 1999 model year onward, the second generation VT Roadster received an updated interior, as well as larger brakes and the new fixed headlamp units. Among other improvements, the updated VT Roadster was fitted with a more powerful version of Lamborghini's 5.7L V12, which saw total power jump to 529hp. While production for the standard second generation VT Roadster ended in 1999, a special run of 30 Millennium Edition Roadsters were built in 2000. These cars were almost identical mechanically to the VT Roadster, but featured a different differential, as well as cosmetic changes unique to the Millennium Edition.
