The U.S.-spec 2012 Mazda5 is likely the last vehicle to bear the now-famous (or, to some, infamous) Nagare design language. Aside from the new sheetmetal, the six-seater mini-minivan gets an updated interior similar to that of the Mazda3 compact and a new four-cylinder engine that provides slightly more horsepower. The 2.5-liter mill makes 157 horsepower in the Mazda5, a 4-horse improvement over the outgoing 2.3-liter unit. Like the old powerplant, it will be offered with a manual or automatic transmission, though we don't yet know if either will be receiving an extra cog. Currently, both transmissions offered on the Mazda5 are five-speed units.
