2018 Mazda3: Significant Upgrades Make This Compact Car Shine

2018 Mazda3

The 2018 Mazda3 represents a thoughtful evolution of Mazda's popular compact car, bringing meaningful improvements to safety, standard equipment, and value across all trim levels. While maintaining the model's renowned driving dynamics, Mazda enhanced the package with more standard features and strategic pricing adjustments that make the 2018 version particularly compelling for buyers in the competitive compact segment.

Key Changes for the 2018 Model Year

Mazda implemented several noteworthy updates to the 2018 Mazda3 lineup that significantly improved its value proposition:

Safety First Approach

The most significant upgrade came in the form of expanded standard safety technology. Even base Sport models now include Mazda's Smart City Brake Support (SCBS), a low-speed front collision mitigation system with automatic emergency braking. This previously optional safety feature became standard across the entire 2018 Mazda3 lineup, reflecting Mazda's commitment to accessible safety technology.

Powertrain Enhancements

Midrange Touring models received a substantial upgrade with the 2.5-liter four-cylinder engine becoming standard equipment. This 184-horsepower powerplant delivers noticeably stronger performance than the base 2.0-liter engine, particularly in highway passing situations and when carrying passengers or cargo.

Value-Focused Pricing Strategy

Mazda maintained competitive pricing while adding features, with the Grand Touring trim seeing no price increase and Touring models actually decreasing slightly in price compared to similarly equipped 2017 models. This strategic pricing, combined with additional standard features, resulted in better overall value for 2018 buyers.
