For 2018 the Mazda3 receives minor but significant updates. The 2.0-liter engine is no longer available in the Touring trim level. Touring models are now powered by the 2.5-liter also used in the Grand Touring. Also, Mazda’s Smart City Brake Support system is now standard on the Sport model.
For 2017, the Mazda3 sees some shuffling of features, trim names and packaging, as well as a modest exterior and interior makeover. G-Vectoring control is made standard, as is an electronic parking brake, while cars equipped with the 2.0-liter Skyactiv engine and automatic transmission receive a Sport Mode function.
With the i SV exiting stage left, the i Sport is now the base model in the 2016 Mazda3 lineup. It arrives with a $600 price cut, to $18,665, and the addition of a standard rearview camera. Also new are trim-specific equipment packages for Mazda's compact sedan and hatchback.
