Turin’s skyline was filled with a Lamborghini Reventón and military helicopter yesterday, as the company flew the supercar – one of only 20 made – to the rooftop of the Lingotto building, closing a conference. The promotional manoeuvre was co-ordinated by the Italian Marines.

The conference explored the timescales, design and production abilities demonstrated by Lamborghini in producing its €1million euro supercar, of which all 20 units have been sold worldwide.
