Inside and out, the Mazda 3 is attractive, and plenty of elements give it a more upmarket appeal. On the road, it's not just competent; it's actually entertaining and sporty to drive. Even if you're not into performance, this translates to a feeling that the car will respond to emergency maneuvers with confidence and ease. Mazda3 got a bunch of improvements for the 2017 model year. For 2018, there are few changes. Automatic emergency braking becomes standard equipment on the 2018 Mazda3. Called Smart City Brake, Mazda's automatic emergency braking system can prevent a collision at speeds up to 12 miles per hour. There's an optional system called Smart Brake that can stop the car at higher speeds. More available safety equipment for 2018 includes active lane control and automatic headlights.
