The Mazda CX-90 3.3 e-SKYACTIV-D (254 Hp) Mild Hybrid i-ACTIV AWD Automatic represents Mazda’s entry into the three-row SUV segment, launched in April 2023. Positioned as a premium offering, it aims to compete with established players like the Acura MDX and Buick Enclave, while offering a distinctly Mazda driving experience. This variant, powered by the 3.3-liter inline-six diesel engine with mild-hybrid assistance, is a key component of the CX-90 lineup, offering a balance of performance, fuel efficiency, and sophisticated technology. The CX-90 utilizes Mazda’s new rear-wheel drive biased platform, a departure from the front-wheel drive architecture of previous Mazda SUVs.

Powertrain & Engine Architecture
The heart of the CX-90 3.3 e-SKYACTIV-D is Mazda’s newly developed 3.3-liter inline-six diesel engine, designated T3-VPTH. This engine represents a significant departure from Mazda’s previous reliance on four-cylinder engines, aiming for smoother operation and increased refinement. The engine utilizes a high compression ratio of 15.2:1 and a sophisticated turbocharger and intercooler system to produce 254 horsepower at 3750 rpm and a substantial 550 Nm (405.66 lb-ft) of torque between 1500-2400 rpm. The engine employs a diesel commonrail fuel injection system for precise fuel delivery. The mild-hybrid system, featuring a 48V lithium-ion battery and a small electric motor (17 hp and 153 Nm of torque), provides assistance during acceleration and enables smoother start-stop operation. The electric motor is positioned between the engine and the transmission. The engine is longitudinally mounted, contributing to the rear-wheel-drive bias of the platform.
Driving Characteristics
The CX-90 3.3 e-SKYACTIV-D with the eight-speed automatic transmission delivers a refined and capable driving experience. The diesel engine provides ample low-end torque, making it well-suited for everyday driving and towing. While not overtly sporty, the CX-90 feels composed and stable, with the rear-wheel-drive bias contributing to a more balanced feel. The eight-speed automatic transmission is generally smooth and responsive, although some reviewers have noted occasional hesitation during downshifts. Compared to potential gasoline-powered variants, the diesel offers superior fuel economy and a more relaxed cruising experience. The mild-hybrid system provides a subtle boost during acceleration, enhancing responsiveness without significantly altering the driving character.
Equipment & Trim Levels
The CX-90 3.3 e-SKYACTIV-D typically comes well-equipped, even in its base trim levels. Standard features generally include Mazda’s i-Activsense suite of safety technologies (including adaptive cruise control, lane-keeping assist, and blind-spot monitoring), a large infotainment touchscreen with Apple CarPlay and Android Auto integration, leather upholstery, and heated front seats. Higher trim levels add features such as a premium audio system, ventilated front seats, a panoramic sunroof, and Nappa leather upholstery. Interior materials are generally of high quality, reflecting Mazda’s commitment to a premium feel.
Chassis & Braking
The CX-90 utilizes a double wishbone front suspension and an independent multi-link rear suspension with a stabilizer bar. This setup provides a comfortable ride while maintaining good handling characteristics. The CX-90 is equipped with ventilated disc brakes on all four wheels, with larger discs at the rear (350mm) compared to the front (347mm). The electric power steering provides a responsive and well-weighted feel. The chassis is designed to accommodate the larger inline-six engine and the all-wheel-drive system, resulting in a relatively heavy vehicle.
Market Reception & Comparison
The Mazda CX-90 has been generally well-received by automotive critics, who praise its refined driving experience, upscale interior, and strong diesel engine. The fuel economy of the 3.3 e-SKYACTIV-D variant is a significant selling point, offering a noticeable advantage over comparable gasoline-powered SUVs. However, some reviewers have noted that the infotainment system can be complex to use and that the third-row seating is best suited for children. Compared to other trims in the CX-90 lineup, the diesel variant offers a different driving character, prioritizing torque and fuel efficiency over outright performance.
Legacy
The Mazda CX-90 represents a significant step forward for Mazda, showcasing its commitment to innovation and premium quality. The 3.3 e-SKYACTIV-D engine, while relatively new to the US market, is expected to prove durable and reliable, building on Mazda’s reputation for engineering excellence. The long-term reliability of the mild-hybrid system remains to be seen, but Mazda has a track record of producing dependable hybrid vehicles. On the used car market, the CX-90 3.3 e-SKYACTIV-D is likely to hold its value well, appealing to buyers seeking a refined, fuel-efficient, and well-equipped three-row SUV.
