Powertrain & Engine Architecture
At the heart of the CX-90 PHEV lies Mazda’s 2.5-liter e-SKYACTIV-G inline-four cylinder gasoline engine. This engine, designated as part of the SKYACTIV family, emphasizes efficiency through high compression (13:1) and direct fuel injection. The engine utilizes a DOHC (Double Overhead Camshaft) valvetrain with S-VT (Sequential Valve Timing) to optimize performance across the rev range. Coupled with this engine is a 173 horsepower electric motor, integrated between the engine and the eight-speed automatic transmission. The electric motor draws power from a 17.8 kWh lithium-ion battery pack positioned under the floor and between the front and rear seats. The combined system output reaches 323 horsepower and 500 Nm (368.78 lb-ft) of torque. The transmission is an eight-speed automatic, specifically tuned to work seamlessly with both the gasoline engine and the electric motor, providing smooth and efficient power delivery.
Driving Characteristics
The CX-90 2.5 e-SKYACTIV-G PHEV offers a refined driving experience. In electric-only mode, it provides quiet and smooth acceleration, suitable for short commutes. When the gasoline engine engages, the transition is nearly imperceptible. The combined power output delivers brisk acceleration, making highway merging and overtaking effortless. The eight-speed automatic transmission is well-programmed, offering responsive shifts and contributing to overall efficiency. While not a sports SUV, the CX-90 handles corners with composure, thanks to its well-tuned suspension. Compared to the non-hybrid CX-90 variants, the PHEV model offers significantly improved fuel economy and a quieter cabin experience. The added weight of the battery pack is noticeable, but the instant torque from the electric motor helps mitigate any perceived performance loss.
Equipment & Trim Levels
The CX-90 2.5 e-SKYACTIV-G PHEV typically comes well-equipped, even in its base trim. Standard features often include leather upholstery, a large touchscreen infotainment system with Apple CarPlay and Android Auto integration, a premium sound system, and a comprehensive suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Higher trim levels add features like a panoramic sunroof, ventilated front seats, and a head-up display. 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, both incorporating stabilizer bars to minimize body roll. The suspension is tuned for a balance between comfort and handling. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and brake assist. The i-ACTIV AWD system intelligently distributes torque between the front and rear wheels based on driving conditions, enhancing stability and traction.
Market Reception & Comparison
The Mazda CX-90 PHEV has been generally well-received by automotive critics, praised for its stylish design, refined driving dynamics, and fuel efficiency. However, some reviewers have noted the limited third-row space and the relatively high price point compared to some competitors. Compared to the standard gasoline-powered CX-90 models, the PHEV offers superior fuel economy and a more refined driving experience, but it comes at a higher cost. Against rivals like the Acura MDX and Volvo XC90, the CX-90 PHEV offers a compelling alternative, particularly for buyers who prioritize driving enjoyment and a premium interior.
Legacy
As a relatively new model, the long-term reliability of the CX-90 2.5 e-SKYACTIV-G PHEV powertrain remains to be fully established. However, Mazda has a strong reputation for building reliable vehicles, and the SKYACTIV engine family has proven to be durable. The plug-in hybrid system adds complexity, but Mazda’s engineering expertise suggests that it should be a reliable component. On the used car market, the CX-90 PHEV is expected to hold its value well, particularly as demand for plug-in hybrid SUVs continues to grow. Its combination of fuel efficiency, performance, and luxury should make it a desirable option for buyers seeking a premium three-row SUV.
