Production of the Reventon Roadster is limited
to just 20 cars
exactly two years after the hardtop version was released. Both
cars made their public debut at the Frankfurt Motor Show (Coupe
in 2007, Roadster in 2009). Just like the Reventon
coupe, the Roadster's styling was inspired by the angular
and aggressive lines of modern fighter jets like the F-22 Raptor
and F117A Stealth.
The lines of the Reventon Roadster are basically identical to
that of the hardtop model. The only major differences are the
obvious lack of a fixed roof, and a new engine cover which incorporates
a unique 'spine' which runs down the centre.
The base bodyshell of the Reventón is already so stiff
that the Roadster requires only minimal reinforcement to compensate
for the lack of a roof. Like the Coupé, the cell of the
Reventon Roadster is made from high-strength steel profile and
carbon components joined with specialist adhesive and rivets.
The bodyshell is made almost entirely from carbon fiber elements,
with sheet steel used only for the outer door skins.
Powering the Lamborghini Reventon Roadster is the same 6.5 litre
V12 engine from the coupe. This is good for a 3.4 seconds 0-60
mph time, and a top speed in excess of 200 mph. Two chains drive
its four camshafts that, in turn, operate the 48 valves. Together
with the three-phase adjustable intake manifold, the variable
valve timing delivers a meaty torque build-up. Dry sump lubrication
ensures that the hi-tech power unit has a constant supply of
oil, even under heavy lateral acceleration.
The bodywork of the Reventon is formed from composite carbon
fiber. This is then glued and riveted to the steel and carbon
fibre construction chassis.
