Mazda MAZDA3 vs Nissan Sentra

The 2026 Mazda MAZDA3 exhibited a distinctive design that aligned with Mazda's signature style, reminiscent of models like the Miata and CX-5. Its front featured a large polygonal grille with a metallic frame that seamlessly integrated with narrow headlights, offering a refined and substantial appearance. The side profile was marked by gracefully sculpted panels and a shiny metallic strip tracing the windows, creating a sportier look. The rear end maintained a harmonious design, avoiding flashy novelties. Inside, the cabin rivaled entry-level luxury vehicles with a tastefully designed dashboard, soft-touch surfaces, and genuine stitching, although the top-most door panel section resembled vinyl more than simulated leather. The Carbon Edition model added a racier look with red leather upholstery, setting it apart from competitors.

The 2026 Nissan Sentra, in its ninth generation, showcased a more dramatic exterior with a massive grille and slim projector LED headlights, giving it an aggressive look. Available in four trim levels, the Sentra offered competitive pricing, with the SR and SL trims providing the best value. The SL trim appeared reserved in muted colors, while the SR trim, especially in Energetic Ember with a contrasting Super Black roof, resembled a sports car. The SR trim, equipped with the Premium Package, featured synthetic leather seats with contrast stitching and a power-adjustable driver's seat. The Sentra's interior boasted a fully digital driver information display and a 12.3-inch center touchscreen, adding a modern touch to the dashboard.

The 2026 Mazda MAZDA3 offered two drivetrain options. The 2.5 S Carbon Edition trim featured a 2.5-liter four-cylinder engine producing 191 horsepower and 186 pound-feet of torque, paired with a six-speed automatic transmission. The Turbo model increased output to 227 hp and 310 lb-ft of torque on regular fuel, with premium fuel boosting it to 250 hp and 320 lb-ft. The base engine provided adequate power, with a 0-60 mph time of around 8.5 seconds, while the Turbo powertrain achieved 0-60 mph in 6.5 seconds. The Mazda 3 stood out with its optional i-Activ AWD system, enhancing traction and cornering stability. Despite its sporty handling, the Mazda 3 maintained a comfortable ride, smoothing over bumps and potholes.

The 2026 Nissan Sentra retained its driving dynamics from previous years, focusing on smooth operation and cost-effectiveness. Its 2.0-liter four-cylinder engine delivered 149 horsepower and 146 pound-feet of torque, with fuel economy estimates of 29 mpg city, 38 highway, and 33 combined for the S and SV trims. The Sentra's CVT was refined for smoother acceleration, though it remained loud during acceleration. The Sentra excelled as a quiet commuter car, with well-weighted steering and managed pedals. A drive mode selector offered minimal improvement in throttle response. The Sentra prioritized tech, price, and interior appointments over performance, making it less exciting to drive.

The 2026 Mazda MAZDA3 offered stylish design and performance but lacked practicality. The front seats provided ample space, but the rear seats were cramped for taller passengers. The sedan's trunk held 13.2 cubic feet of cargo, with a nearly flat load floor when the rear seats were stowed. The hatchback offered more space, with 20.1 cubic feet of cargo capacity. Personal-item storage was limited, with moderately sized cupholders and door pockets.

The 2026 Nissan Sentra's SR and SL trims featured interiors that exceeded their price tags. The dashboard was a significant improvement, with ambient lighting and two-tone leatherette options. The climate controls were touch-sensitive icons, and the Sentra offered tandem-style cupholders and a large center console bin. Rear-seat legroom was tight, similar to the Toyota Corolla, but headroom was adequate for adults. The redesigned trunk had a wider opening and lower load height than competitors. Nissan's zero-gravity seats provided comfort and support.

The 2026 Mazda MAZDA3 lagged in technology, with a standard 8.8-inch infotainment display that wasn't a touchscreen. Higher trims featured a 10.25-inch touchscreen with touch input for Apple CarPlay and Android Auto. The infotainment system was intuitive, but the standard eight-speaker Bose audio system lacked clarity. A 12-speaker Bose audio system was available on the top trim. Mazda Connect allowed remote monitoring and control via a smartphone app, with Alexa Built-in for limited voice control.

The 2026 Nissan Sentra impressed with modern tech, featuring a large, bright touchscreen with customizable menus. The Nissan Intelligent Key allowed for automatic unlocking and locking. The Sentra SR included a myQ Universal Garage Door Opener. Three USB-C ports were standard, with wireless phone projection available on higher trims. The SL and SR trims offered an eight-speaker Bose stereo, and a wireless device charger was standard on the SR and SL. The Sentra aimed to attract buyers seeking a high-tech experience in a budget-friendly vehicle.

The 2026 Mazda MAZDA3 received a five-star rating from the NHTSA and a Top Safety Pick+ award from the IIHS. Standard safety features included i-Activsense, with forward collision warning, adaptive cruise control, lane-departure warning, and more. The Carbon Edition sedan's adaptive cruise control had delayed reactions, causing occasional collision warnings.

The 2026 Nissan Sentra had not been crash-tested by the NHTSA or IIHS at the time of writing. It featured Nissan Safety Shield 360, with automatic emergency braking, lane-departure mitigation, and forward collision warning. New for 2026, blind-spot intervention was included. The Sentra also offered a surround-view monitor and Nissan ProPilot Assist on higher trims.
