Yes, Lamborghini warns, there may come a day when a Lamborghini supercar may not be powered by a large-displacement twelve-cylinder – but for now, why worry? The Aventador is here, and boasts a honkin’ 6.5-liter twelve-pot that’s good for a wicked 691 hp. Launch it right, and the Aventador runs from 0-60 mph in three seconds and hits a top end of 217 mph.
