The Lamborghini Diablo VTTT (the VTTT stood for viscous traction twin turbo) was a limited production (7 made altogether) made by Platinum Motors in California.
The cars were equipped with twin Garrett T4 turbochargers with custom-built intercoolers, competition valves with race guides, cylinder heads with polished ports, and a reprogrammed electronic fuel injection system. Modifications to the drivetrain included a custom Kevlar twin-plate clutch to cope with the extra torque and a new short ratio gearbox to improve acceleration. The brakes were upgraded with cross-drilled, ventilated discs and carbon fiber brake pads.
With 750 hp, the 222 mph was a surprise to nobody.
