Like the Murciélago and Gallardo that followed it, the Diablo was never formally split into generations by Lamborghini; it ran for eleven years on one platform, revised repeatedly, and this entry follows that structure by treating each major revision as a trim rather than inventing generation boundaries the car itself never had.[1]
The clearest documented split is drivetrain: the base 1990 Diablo was rear-wheel drive only, and the 1993 VT added a viscous-coupled all-wheel-drive system that could send up to 25% of torque forward. Both made the same 492 PS/362 kW at launch (the VT’s difference was traction, not output), and Wikipedia’s own specification table gives each drivetrain a different front/rear weight split (41/59 rear-drive, 43/57 all-wheel drive), which is recorded here rather than assumed.
The 1999 facelift replaced the pop-up headlamps with fixed units borrowed
under licence from the Nissan 300ZX, added variable valve timing, and lifted
the SV to 530 PS/390 kW. The final VT 6.0 stroked the block to six litres; the
article states the stroke change (80 mm to 84 mm) but not the resulting
displacement directly, so that figure is recorded as estimated rather than
verified, with the basis stated in its own note.
