During the U.S. presentation of the new 2012 Fiat 500,  the Italian company's Chief Engineer Fabio Dimuro explained to  journalists the main differences and changes compared to the European  specification model. These include - but are not limited to- exterior  and interior improvements, the introduction of a more appropriate for  American consumers Aisin 6-speed automatic transmission, additional  insulation that helped reduce powertrain noise levels from 76 db to 71  db, the addition of MultiAir intake system to the 1.4-liter engine,  while Fiat and Chrysler also worked together to redesign the car's  rear-axle.
