This video was taken at Nürburgring and shows Lamborghini testing the new Huracan Superleggera. The Superleggera is the hardcore version of the Huracan, and will be around 100kg lighter and has a power increase of 10-20hp, so it will get 620-630hp in total.
As you can see, the exhaust pipes are moved to the middle of the rear bumper, a bit like the Scuderia/Speciale from Ferrari. The car will be introduced later this year in Paris or next year in Geneva.
