The Mazda CX-90 3.3 e-SKYACTIV-G (340 Hp) Mild Hybrid i-ACTIV AWD Automatic represents Mazda’s entry into the three-row premium crossover segment, launched for the 2023 model year. Positioned as the flagship of the CX line, it aims to compete with vehicles like the Acura MDX and Infiniti QX60. This variant, featuring the potent 3.3-liter turbocharged inline-six engine paired with a mild-hybrid system and an eight-speed automatic transmission, is a key offering within the CX-90 range, targeting buyers seeking a blend of performance, luxury, and fuel efficiency. The CX-90 utilizes Mazda’s new rear-biased all-wheel-drive platform, a departure from the front-wheel-drive bias of previous Mazda crossovers.

Powertrain & Engine Architecture
At the heart of the CX-90 3.3 e-SKYACTIV-G lies Mazda’s new 3.3-liter inline-six engine, designated as the G340. This engine represents a significant departure from Mazda’s traditional four-cylinder engines, offering a smoother and more refined power delivery. The engine utilizes a sophisticated direct injection system and a twin-scroll turbocharger with an intercooler to produce 340 horsepower at 5,000 rpm and 500 Nm (368.78 lb-ft) of torque at 2,000 rpm. The mild-hybrid system, consisting of a 48V lithium-ion battery and an integrated electric motor, provides a small power boost (17 hp and 153 Nm) and assists in smoothing out the start-stop system. The electric motor is integrated directly into the eight-speed automatic transmission. The engine features a high 12:1 compression ratio and Mazda’s S-VT (Sequential Valve Timing) technology for optimized performance and efficiency. The longitudinal engine layout contributes to the rear-biased all-wheel-drive system.
Driving Characteristics
The CX-90 3.3 e-SKYACTIV-G delivers a noticeably more powerful and refined driving experience compared to Mazda’s four-cylinder offerings. The eight-speed automatic transmission is well-tuned, providing smooth and responsive shifts. While not overtly sporty, the CX-90 offers ample acceleration for highway merging and passing maneuvers. The rear-biased all-wheel-drive system enhances handling stability and provides a more engaging driving feel. Compared to potential future turbocharged four-cylinder variants, this 3.3L offers a more linear power delivery and a more premium feel. The mild-hybrid system contributes to improved fuel economy, particularly in city driving, but the performance gains from the electric motor are subtle.
Equipment & Trim Levels
The CX-90 3.3 e-SKYACTIV-G is typically offered in higher trim levels, such as Touring Premium, Premium Plus, and the top-tier Turbo Premium. Standard features generally include leather upholstery, a large touchscreen infotainment system with wireless Apple CarPlay and Android Auto, a premium sound system, and a comprehensive suite of advanced driver-assistance systems (ADAS) including adaptive cruise control, lane-keeping assist, and blind-spot monitoring. Optional extras may include a panoramic sunroof, Nappa leather seats, and a rear-seat entertainment system. The interior design emphasizes a minimalist aesthetic with high-quality materials and meticulous attention to detail.
Chassis & Braking
The CX-90 utilizes a robust chassis with a double wishbone front suspension and an independent multi-link rear suspension, both incorporating stabilizer bars. This setup provides a comfortable ride while maintaining good handling characteristics. The CX-90 features ventilated disc brakes at all four corners, with larger diameter rotors on the front axle (347.98 mm) compared to the rear (350.52 mm). The braking system is augmented by ABS (Anti-lock braking system), electronic brake-force distribution, and brake assist. The suspension tuning is geared towards providing a balance between comfort and control, suitable for both daily commuting and long-distance highway driving.
Market Reception & Comparison
The Mazda CX-90 has been generally well-received by automotive critics, who praise its refined powertrain, upscale interior, and engaging driving dynamics. However, some reviewers have noted that the third-row seating is somewhat cramped compared to some competitors. Compared to other trims in the CX-90 lineup, the 3.3 e-SKYACTIV-G offers a significant performance advantage, but at a higher price point. Fuel economy is competitive within the premium crossover segment, although not class-leading. Reliability is expected to be good, based on Mazda’s reputation for building durable vehicles, but long-term data is still emerging.
Legacy
The Mazda CX-90 3.3 e-SKYACTIV-G represents a pivotal moment for Mazda, showcasing its commitment to building premium vehicles with sophisticated technology and engaging driving dynamics. The 3.3L inline-six engine is expected to become a mainstay in Mazda’s lineup, potentially appearing in other models in the future. The long-term reliability of this powertrain remains to be seen, but Mazda’s track record suggests it will be a durable and dependable unit. As the CX-90 matures in the used car market, the 3.3 e-SKYACTIV-G variant is likely to command a premium due to its superior performance and refinement.
