cica si ferrari ar fi construit motorul pe acelasi principiu ca si mercedes dar nu chiar Ferrari had the same idea as Mercedes, and their compressor is also detached from the turbine. But the Italian team did not go as far as Mercedes in pursuing the concept. Their compressor is only about a third of the way or so across the 'v' of the engine from the turbine, rather than on the other side. Perhaps Ferrari were worried about being able to control the vibrations in the shaft connecting the turbine and compressor if it was as long as the engine. Given this shaft spins at 120,000rpm, that is certainly a huge challenge, and one that Mercedes have met. Whatever the reason, Ferrari's engine department have the agony of knowing that they, too, hit on the idea that has emerged as the key performance differentiator in F1 in 2014, but did not pursue it as far as they could have done.
