Lamborghini launched a facelifted Diablo in 1999. The most immediately noticeable exterior change was the replacement of the previous Diablo’s pop-up headlamp units with fixed composite lenses. All Diablos were also fitted with new 18 inch wheels. The Diablo range also received an updated interior.
The V12 powerplant was stretched tp 529 hp and 446 lb ft of torque for both the SV and VT models and now featured variable valve timing. For the first time in a Lamborghini, the Diablo was equipped with a Kelsey-Hayes ABS unit, complementing larger diameter brake rotors.
