Technical data

The Roadster differs from Lamborghini Murcielago Coupe in certain important technical details. Various structural chassis components - in steel and carbon - have been redesigned to ensure adequate torsional stiffness, even though there is no roof.

In particular, there is a special stiffening lattice on the engine compartment structure. As an optional feature, this lattice is also available in a visible carbon fibre version.

Without altering the extreme features of the car, there is also the option of mounting a soft top roof ("R-top") which, as in the tradition of this kind of model, is only designed for temporary use (for example in the case of sudden rain) and at a recommended maximum speed of 160 km/h.

Particular attention has been paid to safety. As mentioned previously, Lamborghini Murcielago Roadster is equipped with an automatic, electronically-controlled roll bar, which extends from its housing behind the seats in only a few milliseconds during a roll-over emergency.

The overall dimensions are the same as for the coupe: length is 4580 mm, width is 2045 mm, wheelbase is 2665 mm, front track is 1635 and rear track is 1695 mm. The only variation is in height: the Murcielago Roadster is 70mm lower than the coupe.

The dry weight is 1650 kg, with a weight distribution of 42% at the front and 58% at the rear.

The engine is obviously the Lamborghini 12 cylinder 60 deg. V, with a displacement of 6192 cc, producing 580 hp (426 kW) at 7500 rpm and a maximum torque of 650 Nm at 5400 rpm. The engine features the Lamborghini L.I.E. electronic engine management system. The standard gearbox is a 6-speed manual, like the Coupe. As an optional feature, a 6-speed "e-gear" automatic version is available.

There is also Lamborghini permanent four-wheel drive on the Roadster, with a central viscous coupling and limited slip rear and front differentials (45% rear, 25% front).

There is independent front and rear double wishbone suspension and anti-roll bars with front "Antidive" and rear "Antisquat" systems. Koni FSD (Frequency Selecting Dampers) self-adjusting shock absorbers are used.

The braking system is the H-type with power braking, with ABS and four ventilated disks.

The wheel rims are aluminium alloy with dimensions of 8.5'' at the front and 13'' at the rear, with Pirelli Rosso 245/35ZR 18 tyres at the front and 335/30ZR 18 at the rear.

The maximum speed of the Murcielago Roadster (depending on aerodynamic configuration) is circa 320 km/h. The recommended maximum speed with the roof in place is 160 km/h.

Lamborghini Murcielago Roadster takes 3.8 seconds to go from 0 to 100 km/h.

Despite the absence of the roof, structural modifications have ensured excellent levels of rigidity. This rigidity and the optimised suspension ensure that driveability and performance are definitely not inferior to those of the Coupe. Lap times for the two versions of Lamborghini Murcielago at various handling circuits have proven to be more or less identical.


Interior

Lamborghini Murcielago Roadster is more extreme and exclusive than ever, also with respect to the interior. This has "asymmetrical" leather upholstery: the left side has different material compared to the right and is perforated. That part of the cockpit designed for the driver is oriented towards him/her, so it is a real "Pilot Oriented Challenger".
