The Lamborghini Diablo is a high-performance supercar built between 1990 and 2001.
About The Diablo VT 6.0
In 1998 Lamborghini was taken over by Audi. They wanted to make major revisions to the Diablo so that it could continue to provide revenue while its replacement, the Lamborghini Murciélago was then developed. The VT 6.0 was their first (and last) truly intensive redesign of the car, meaning that it was more than just a cosmetic update to the existing model. Heavy styling changes were made both on the inside and the outside. The air intakes and the front bumper were remodeled as well as the entire dashboard and the nose.
The switchgear and the seats were also improvised and changed.
The motor was updated with ECU software in addition to a new exhaust and intake system as well as a refined variable valve timing system with slightly less aggressive camshafts than had previously been used in the versions that were made earlier. 1999-2001 Diablo GT (Only 80 of them built)
The 1999-2001 Diablo Gt Lamborghini was built in an extremely limited edition, only 80 Diablo's GT will leave the factory.
The Original Diablo GT from Lamborghini was considered to be the fastest production car in the world.The reason the Diablo GT Lamborghini is considered on of the most high performance road cars in the world is because it is derived from the experience that was gained by the development of the GT2 raced car. You combine that with the competence of Lamborghini's production and experience, the result is a high performance sports car, drivable on open condition roads which in a winning combination.
The Lamborghini Diablo GT has many advanced technical features that's worthwhile to explain in detail.
Engine
The Lamborghini 6 liter V12 engine, particularly conceived for superior performance (max power 575 PS (423 kW) at 7300 rpm, max torque 630 Nm at 5500 rpm).
Multi-throttles intake manifold ("individual intake system": one throttle unit per each cylinder), with improved runners for high flow coefficients
new intake and exhaust camshafts, tuned to achieve very high charge efficiency at medium-high engine speeds intake variable valve timing system (derived from the well proven system already used on Diablo's model year '98 and '99) in order to guarantee good charge efficiency and then good torque not only at high but also at low engine speeds
dynamic air inlet duct upstream the intake plenum for additional improvements of charge density and then engine power with the increasing of car speed
aluminum construction (as Lamborghini's tradition) with magnesium intake manifold and cylinder head covers titanium connecting rods and lighter crankshaft
improved exhaust system for reduced backpressure, with Lamborghini ENCS (Exhaust Noise Control System) for Noise control Engine Management System
In order to match the characteristics of the new multi-throttles intake manifold a new version of Lamborghini's proprietary electronic engine control "LIE" has been developed, it doesn't only guarantee high performances but also food drivability at low speeds and the respect of emission requirements. The new system has been designed as a combination of
"speed density" and "throttle speed" concepts:
Fuel injection is sequential multipoint
Ignition is static, with individual coils
Lamborghini Data Acquisition System (LDAS) and diagnostic functions are integrated in the system
Exhaust Noise Control System (ENCS)
It is a further development of the noise control system already adopted in the current Diablo range.
A special design of the exhaust pipes, together with a variable geometry system based on the actuation of two vavles (controlled by the engine management system), enables a control of the exhaust noise at low and high engine rev. without loss of performances:
at low/medium speeds: throttles closed, each part of the pipe included between the throttle and the "1 in 2" or the "2 in 1" junction acts as a noise filter (for each bank two resonance pipes with closed end "in parallel" are so created) for medium frequencies at high speeds: throttles opened, the length difference of the pipes between the junctions acts as a noise ("interference effect") for high frequencies Cooling System Traditional Lamborghini's two engine cooling radiators "in parallel" with a new front mounted engine oil cooler.
Transmission
RWD transmission, Lamborghini 5 speed gearbox with various gear ratios options to satisfy different customers' requirements. The gearbox control lever is on the central tunnel, in an asymmetric position closer to the steering wheel for better ergonomics.
Chassis Frame, Suspensions
In comparison with the standard Diablo versions, the GT features a larger front track (+ 110 mm) with modified suspensions and chassis frame in order to achieve optimal handling characteristics for sport driving at high speed. New pedalery and new lightweight aluminum alloy wheels are fitted.
Brakes. The brake and the ABS systems are derived from the well proven high performance systems of the Diablo range with self ventilated large diameter discs (355 mm front, 335 mm rear) with high performance callipers and last generation ABS system. For Lamborghini Diablo GT even better performances are achieved, thanks to the reduced car weight.
Body
Lamborghini Diablo GT combines a new construction technology with a new design. Almost all the body parts are made of carbon fibre, excluding the roof and the doors only:
Front bumper of new design, with integrated air intakes for the new front mounted oil cooler and for the brakes
Rear bumper of new design, "wing shaped"
Front fenders of new design, matching the larger front track
Front bonnet of new design, with integrated air outlet from the oil cooler
Engine bonnet of new design, incorporating the engine dynamic air intake
The Diablo GT is available in 4 colors: orange, titan-silver, black and garish yellow.
Interiors
In the interior, of new design, most components are made of carbon fiber.
Racing seats, racing 4 point safety belts, sporty steering wheel and general sport trimming, leather and Alcantara upholstery, carbon fiber parts "in sight", are all elements that give a sporty feeling to the driver and to the passenger. The air conditioning system is standard equipment to maintain a high comfort level.
Performances
Although Lamborghini Diablo GT is a true road car (conforming to EU safety and emissions requirements), the combination of a very powerful engine, reduced weight and improved suspension provides "race car" characteristics for acceleration, handling and top speed (338 Km/h).
