Lamborghini’s supercar remains one of the last of its kind to follow a truly artisanal manufacturing method, very close to the one used in its early days. In addition to the V12, which is still assembled by hand and bench-tested before being integrated into the body, the tubular chassis is made by Marchesi in Modena, while the aluminium panels for the front trunk, doors and wings are supplied by Golden Car in Cuneo, a specialist who also works for Maserati. The composite body panels, bonnet and fascias are made directly at the Lamborghini factory, in an Autoclave. The cylinder head comes from Fonderia Scacchetti before being finished at Lamborghini. The customisation still permitted by craftsmanship is almost infinite, making many Lamborghini Diablo unique. Beyond the simple customised paint colour, the engine specifications themselves can be adapted, from the gearbox ratios (3 types of axle are available) to the compression ratio! Each car is then tested over 3 60-kilometre sessions, during which the suspension and engine management settings are validated before it is declared ready for delivery. Engines assembled from 1999 onwards can be identified by the inscription ‘Valve Timing Management’ on the central air intake cover. The restyled Lamborghini Diablo SV (or Series 2) was only produced from October 1998 to December 1999.
