The one thing you can loose from the Lamborghini flagship hypercar is the roof. That is just what Lambo has done and therefore the Aventador LP 700-4 Roadster is born.
The roof is actually a two-piece carbon fiber top that you can remove. It is still powered by the same 700 horses 6.5L V12 found in its hard top version. As for acceleration, the car will do 0-100 in 3.0 seconds. Top speed 347 kmh. Price $441,600 in the US. Probably 5m SEK if there was a dealership here.
