Expect to find Mazda's MAZDA CONNECT infotainment system with a 7-inch display, Bose premium audio, leather-trimmed seating, heated front seats, a power moonroof, and advanced driver-assistance features including a blind-spot monitoring system, rear cross-traffic alert, and lane departure warning. The Grand Touring also typically includes adaptive front lighting, a head-up display, and dual-zone automatic climate control — features you'd expect to find in a much more expensive luxury compact. The interior build quality is frequently praised by automotive reviewers as one of the most refined in the segment, feeling closer to an Audi or BMW interior than a typical mass-market compact.
