After skipping the 2011 model year, Mazda offers an all-new 2012 Mazda5 in 2011. A restyled exterior featuring swirling lines is the most noticeable difference. On the inside, the instrument panel and seats are noticeably different, but overall the new model retains the size and efficient packaging that made the prior model remarkable. Under the hood, a larger four-cylinder yields a slight increase in power.
