The Multiair system, which uses its sophisticated software and fast-acting electrohydraulic actuation to send the throttle plate off to the annals of history, appears deceptively simple. The system slots into the cylinder head kind of like a Lego brick, and is easily adaptable to most engines. This being the case, adapting it to the Chrysler engines we already know and love wouldn't be too difficult of a task.
The software to run it all is what Fiat is most proud of; the competition is years behind, it says, and the company has patented its rig. Alfa Romeo already has MultiAir out in the wild with the MiTo, and with the need for fuel efficiency gains in Chrysler's lineup, something that's essentially as easy as snapping pieces together seems very attractive.
