There's a "changing of the guard" element to the facelifted 2012 Mazda5 -- in U.S.-spec trim; the car made its global debut in March at the 2010 Geneva Auto Show -- sharing the Los Angeles Auto Show spotlight with the Shinari Concept. The updated 5, you see, is likely the last Mazda to bear the "Nagare" design language while the Shinari is the example of the Japanese automakers "Kodo" language that should begin propagating throughout its lineup shortly.
Aside from the new sheetmetal, the 2012 Mazda5 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.
