This drawing appears to show that Fiat's clever MultiAir technology is being developed for a V8 application, one that will most likely wind up in a Ferrari.
The MultiAir system, which allows an infinitely variable valvetrain setup via electro-hydraulic actuators, means Fiat's smaller engines can produce better low-end torque and more horsepower more efficiently. The benefits of such improvements to Ferrari motors - better efficiency and fewer emissions without having to sacrifice performance or power - are obvious.
On top of this, the 2D schematic appears to include pneumatically controlled valves. That's the sort of technology Ferrari's F1 engines use to allow its motors to rev beyond 20,000rpm (even though the regulations don't permit those figures), as springs can't handle the valve speeds.
The fascinating implication is that Ferrari could be working on a small-capacity, high-efficiency V8 with a potentially stratospheric rev limit. Sounds intriguing...
