Rather more impressive (and entirely believable) is Lamborghini’s claim that the roadster can reach its astonishing 217mph top speed with or without the roof in place. The highest speed I reached was about 160mph along the main straight at the Homestead-Miami Speedway, at which point any noise being generated by the wind was drowned out completely by the machinations of that monster V12.
At lower speeds, however, it’s clear that Lamborghini's designers and aerodynamicists have done a fine job of managing the flow of air away from the cockpit: at 80mph with the windows up and the small rear bulkhead screen raised, conversation is remarkably easy to maintain.
Unlike the Murciélago Roadster, there’s a genuine level of refinement to this car’s demeanour when you’re driving it al fresco, up to and beyond three figures.
But the best mode to drive it in is with the roof up and the bulkhead panel that sits behind your head down. This tiny glass panel is the only thing that separates your ears and brain from the screaming, 691bhp V12, and when you lower it the volume levels become cataclysmic.
You can almost smell the unleaded being burned, and it sounds far, far angrier – and louder – than the coupé does at any point within the 8500rpm rev range. You sometimes wonder if your ears might actually be getting damaged.
The 1625kg Lamborghini can sprint from 0-62mph in just 3.0sec, thanks to the traction on offer from its four-wheel drive system and the almighty 691bhp and 507lb ft the V12 offers up. Lamborghini even claims a relatively acceptable 17.5mpg average for it, although emissions of 370g/km of CO2 won't win you any favours when it comes to road tax.
Faults? The ride is skateboard stiff on the public road and the steering weights up too quickly and too much in quick corners. And despite the excellence of the transformation from coupé to roadster, the Aventador still feels like a big, heavy, almost clumsy machine if and when you start to throw it around. But fundamentally it is what it is, and you’ll either love it or hate it for that.
Times may be hard for mainstream car manufacturers at the moment, but for the likes of Lamborghini the opposite is true in 2013, and it’s the Asian market that’s keeping trade strong. Hence the reason why, even at £288,840, the roadster is sold out until mid-way through next year.
