As we count down the days to the start of the Shanghai Auto Show, images and details of a new special Aventador have emerged from Germany's Auto Bild magazine. Celebrating Lamborghini's 50th anniversary, the Aventador LP720-4 50th Anniversary edition features a number of special upgrades. Principal among them is a retuned version of the Aventador's 6.5-liter V12 engine that now produces 720 metric horsepower. That's 20 more than the standard Aventador, but 30 less from the version in the Veneno.
