Autospeed has a piece about the technology:
MultiAir Technology - Looking at the Fiat Group's innovative new variable valve system
Noteworthy:
Quote:
- Maximum power is increased by up to 10 per cent thanks to the adoption of a power-orientated mechanical camshaft profile.
- Low RPM torque is improved by up to 15 per cent through early intake valve closing strategies that maximise the air mass trapped in the cylinders.
- Elimination of pumping losses brings a 10 per cent reduction in fuel consumption and CO2 emissions, both in naturally aspirated and turbocharged engines with the same displacement.

They also repeat that Fiat is planning a 2-cylinder auto engine using this tech. Surely we'll see
that in a North American Chrysler product in the future.
