Lamborghini is presenting the new version of the Lamborghini Murcielago Roadster at the 2006 Los Angeles Auto Show. The Lamborghini Murcielago LP640 Roadster benefits from the same extensive modifications to the bodywork and mechanics as the LP640 Coupe, as well as delivering its own distinct character.
Even More Aggressive Design
In their re-interpretation of the Roadster, the designers of the Lamborghini Centro Stile have remained true to the original style principles of purism, sportiness and functionality. As with the Coupe it has now assumed a more aggressive appearance, a substantial influence being the new front and rear bumpers. On the latter there is a new rear diffuser, in which the exhaust system is integrated within a tailpipe. The rear lights are also new, increasing the distinguishing features and making the Murcielago Roadster as unmistakable at night as in daylight. The asymmetrical design of the sides is particularly striking. Whilst the area behind the air inlet on the right is almost closed, on the left there is a large opening for the ventilation of the oil cooler. This, in addition to the aerodynamic form of the front and rear, is an illustration of how functionality dictates the shape of a Lamborghini.
Changes to the rear-view mirror make the Murcielago Roadster more aerodynamic, with other features including new windscreen wipers and the option of new Hermera alloy wheels.
From its forerunner, the Lamborghini Murcielago Roadster LP640 has inherited the characteristic asymmetrical interior arrangement. The whole interior is tailored to the driver and arranged in such a way that a true driver-focused experience is offered; a car which challenges yet at the same time is entirely geared to the driver. This is illustrated in the use of perforated leather for the chair cushions, the dashboard tunnel console and the door lining on the driver’s side.
The instrument panel has also been redesigned with different display graphics. This includes a new Kenwood car radio with a 6.5 inch widescreen monitor and reader for DVD, MP3 and WMA. The navigation system (standard equipment in Japan) is also available as an option.
More Powerful Engine
As with the Coupe the new 6.5-liter (6.496 cm3) 60° V-engine and 640 bhp at 8,000 rpm is now used also in the Lamborghini Murcielago Roadster. At 6,000 rpm the 12-cylinder engine reaches the maximum torque of 487 lb-ft.
The increased power naturally leads to increased road performance. The maximum speed now lies at 205 mph. The standard sprint from 0 to 62 mph is now reached by the Murcielago LP640 Roadster in an excellent 3.4 seconds making it 0.4 seconds faster than its forerunner.
Higher performance and torque naturally mean increased demand on the drive components. A six-gear transmission adapted to these requirements, plus a stronger rear differential and new half-axles, have therefore been deployed in the new Murcielago Roadster. An e-gear transmission with a newly tuned thrust mode (acceleration program) is also available as an option.
Like its forerunner, the new Murcielago Roadster LP640 has permanent four-wheel drive.
Frame and Chassis
Although the Lamborghini Murcielago Roadster LP640 is principally based on the Murcielago Coupe, it has further distinguishing features beyond its distinctive appearance. First and foremost, newly designed frame structure parts made of steel and carbon-fiber guarantee an unswerving torsion resistance even without a roof. A special reinforcement structure in the engine area makes a major contribution to this aspect. This optically distinctive reinforcement can also be delivered in carbon fibre on request. Without impairing the extreme character of a typical roadster, a canvas roof (R.top) can be fitted which, true to the design tradition of this type of vehicle, is principally conceived for temporary use (for example in a sudden shower of rain) and for speeds of up to 100 mph.
With its characteristic wing doors, the bodywork of the Murcielago LP640 Roadster is still made from an extremely high quality combined structure of sheet steel and carbon honeycomb.
The road performance, handling and stability at high speeds benefit from the use of new springs and stabilizers as well as the revising of the electronically controlled silencers. The anti-dive and anti-squat properties of the axles which effectively prevent brake diving and squatting, remain unchanged. The springs (two for each rear wheel and one for each front wheel) and silencers are coaxially aligned.
The new aluminum Hermera rims measure 8 1” x 18” at the front and 13” x 18” at the rear. The vehicle is equipped with mixed tires of the type Pirelli P Zero “ROSSO”: the Murcielago LP640 Roadster is driven at the front on tires with the dimensions 245/35 ZR18 and 335/30 ZR18 at the rear. Pirelli P Zero Corsa tires are available as an option: particularly appropriate for use on race tracks.
