Lamborghini Aventador SV Roadster spied testing undisguised

Lamborghini typically does more versions of its V10 models than it does with its V12s. Just look at how many model variants the Gallardo spun off over its many years of production, compared to the few the Murcielago did. But with both now retired, and the Aventador on the market longer than the Huracan, it's the larger of the two that's beefing up the Raging Bull's product portfolio.

We're looking at and referring to the upcoming Aventador SV Roadster. Lambo has already confirmed that the Superveloce Roadster was in the works, and we even saw a heavily camouflaged prototype undergoing testing near the Arctic Circle. But this time it's completely undisguised, without a shred of camouflage to keep it from our prying eyes.

It isn't hard to guess at the technical details here, since it combines the best attributes of two existing versions: namely the LP 700-4 Roadster and the LP 750-4 Superveloce. So look for a 6.5-liter V12 channeling 740 horsepower to all four wheels through the company's proprietary seven-speed ISR transmission, just like the SV coupe. It'll be a bit heavier with its removable carbon-fiber roof panel and the requisite extra bracing, but it's doubtful the slight weight penalty will actually translate to any substantial drop in performance.

Noticeably absent, however, is the big rear wing that adorns the back of the SV coupe. We'll have to hold tight to find out if the production version will get the spoiler or not, and there's little precedent to go by here since Lambo has never really offered a convertible Superveloce before. With the wing or without, the Lamborghini Aventador LP 750-4 Superveloce Roadster will likely debut at the Frankfurt Motor Show come September, with production already confirmed to be limited to 500 units – or 100 less than the existing coupe that's already sold out.
