Ferrari SF15-T - exhaust/gearbox packaging

It enters through two oval openings in the sidewall of the case, and one large oval opening on the top - only visible in the drawing below (yellow oval) of the Ferrari-powered Sauber. The Swiss team use not only Ferrari’s power unit, but also their gearbox. This allows for a better exhaust package and a slightly lower centre of gravity at the rear of the car. And, of course, it’s a solution that nobody can copy this season.
