Powertrain & Engine Architecture
At the heart of the CX-9 II 2.5 SKYACTIV-G 4×4 Automatic lies Mazda’s PYZ4 engine, a 2.5-liter inline-four cylinder gasoline engine. This engine is a key component of Mazda’s SKYACTIV technology suite, designed to maximize efficiency and performance. The engine utilizes direct injection, a 10.5:1 compression ratio, and a twin-scroll turbocharger with an intercooler. This combination allows for a broad torque curve and responsive acceleration. The engine’s output of 250 horsepower at 5000 rpm and 310 Nm (228.64 lb-ft) of torque at 2000 rpm provides ample power for everyday driving and highway passing. The six-speed automatic transmission was specifically tuned to complement the engine’s characteristics, offering smooth shifts and efficient operation. Unlike some competitors who opted for continuously variable transmissions (CVTs), Mazda retained a traditional automatic, prioritizing a more engaging driving feel.
Driving Characteristics
The 2.5-liter turbocharged engine and six-speed automatic transmission deliver a noticeably different driving experience compared to the naturally aspirated engine options available in earlier CX-9 generations. While not as overtly sporty as some rivals, the CX-9 II 2.5T offers a refined and capable driving experience. The turbocharger provides a noticeable boost in power, making merging onto highways and overtaking other vehicles relatively effortless. The automatic transmission is well-programmed, providing smooth and timely shifts. Compared to a manual transmission equipped CX-9, the automatic prioritizes convenience and ease of use, but sacrifices some driver engagement. The all-wheel-drive system provides enhanced traction in various weather conditions, contributing to a secure and confident driving experience.
Equipment & Trim Levels
The 2.5 SKYACTIV-G 4×4 Automatic trim typically sat in the mid-range of the CX-9 II lineup. Standard features generally included three-zone automatic climate control, Mazda Connect infotainment system with a 7-inch touchscreen display, Bluetooth connectivity, a rearview camera, and keyless entry. Higher trim levels, such as the Signature trim, added features like leather upholstery, a premium sound system, a power moonroof, and advanced safety technologies like adaptive cruise control and lane departure warning. Optional extras for the 2.5T 4×4 Automatic could include navigation, a power liftgate, and heated front seats.
Chassis & Braking
The CX-9 II utilizes a robust chassis with independent suspension at all four corners. The front suspension employs a McPherson strut design with coil springs and an anti-roll bar, while the rear features a multi-link setup. This suspension configuration provides a comfortable ride quality while maintaining good handling characteristics. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is equipped with ABS (Anti-lock Braking System) and electronic brake-force distribution. The CX-9 II’s curb weight of 1969 kg (4340.9 lbs) is relatively competitive for its class, contributing to its balanced handling.
Market Reception & Comparison
The Mazda CX-9 II, and particularly the 2.5 SKYACTIV-G 4×4 Automatic variant, received generally positive reviews from automotive critics. It was praised for its stylish design, upscale interior, and engaging driving dynamics. Compared to competitors like the Honda Pilot and Toyota Highlander, the CX-9 II was often noted for its more refined driving experience and premium feel. Fuel economy was generally considered average for the segment, with EPA estimates around 22 mpg combined. Reliability ratings were generally good, although some owners reported minor issues with the infotainment system.
Legacy
The Mazda CX-9 II 2.5 SKYACTIV-G 4×4 Automatic has proven to be a relatively reliable and durable vehicle in the used car market. The PYZ4 engine, while turbocharged, has demonstrated good long-term reliability with proper maintenance. Regular oil changes and adherence to the manufacturer’s recommended service intervals are crucial for maintaining the engine’s health. The six-speed automatic transmission is also known for its durability. As of today, well-maintained examples of the CX-9 II 2.5T 4×4 Automatic continue to command reasonable prices in the used car market, appealing to buyers seeking a stylish, practical, and engaging three-row crossover SUV.
