"One bike to rule them all." That was the tag line when Specialized announced the new Tarmac. The aim was to launch a bike that offered no compromises on race day. With it, the American brand put the first nail into the coffin of its own aero bike, the Venge, by stating that there would be no advantage for a rider to choose it over the new Tarmac. 

In actual fact, the aerodynamic differences still swing in favour of the Venge - to the tune of 2.5 watts. However, with all metrics factored in, such as rider freshness, handling, acceleration and, of course, weight, the Tarmac was the victor on all of Specialized's course profile simulations.
