Engine Output and Drivetrain Options

The 2026 Honda Civic opens with a 2.0-liter four-cylinder producing 150 horsepower and 133 lb-ft of torque on gas trims, topping out at 200 total system horsepower via its hybrid — all front-wheel drive. The 2026 Mazda3 Sedan starts at 186 horsepower and 186 lb-ft of torque from its Skyactiv®-G 2.5-liter four-cylinder, 36 more horsepower than the Honda Civic base engine. The Mazda3 2.5 Turbo Premium Plus climbs to 250 horsepower and 320 lb-ft of torque on 93-octane fuel — that’s 50 more than the Honda Civic at its peak. The Mazda model also adds standard i-Activ AWD®, so performance and all-weather traction are seamlessly aligned.

Infotainment Display and Standard Audio

Every 2026 Mazda3 Sedan trim includes Mazda Connect™ and an 10.25-inch full-color center display, 1.8 inches wider than the seven-inch touchscreen standard on the Honda Civic LX, so you have more to work with before you consider stepping up. Several Mazda3 trims also include Mazda Harmonic Acoustics with eight speakers; the Honda Civic LX ships with four.

Standard Active Safety Coverage

Honda Sensing® is standard on every 2026 Honda Civic trim, covering Forward Collision Warning, Adaptive Cruise Control, Lane Departure Warning, and Traffic Sign Recognition. The new Mazda model builds on that: Blind Spot Monitoring, Rear Cross Traffic Alert, Mazda Radar Cruise Control™ with Stop & Go, Driver Attention Alert, and Rear Seat Alert are all standard on every Mazda3 trim. Meanwhile, Blind Spot Information System and Rear Cross Traffic Monitor require stepping up to Honda Civic Sport.
