On the mechanical side, the 051 engine, like its predecessor is load
bearing and mounted longitudinally, as is the transmission. The
latter is completely new and novel, especially in the usage of
materials and the method of gear selection. The gearbox, cast in
titanium, has seven sequential gears, hydraulically operated. The
materials used in transmission and engine have been specially
developed to reduce weight and bulk. The exhausts remain high level,
a Ferrari trend now followed by the rest of Formula One.
