The Mazda CX-8 2.5 SKYACTIV-G (192 Hp) Automatic, introduced in 2018, represents a key variant within the first generation (CX-8) of Mazda’s three-row crossover SUV. Primarily aimed at markets outside of North America – notably Japan, Australia, and parts of Asia – the CX-8 was designed to fill a gap between the smaller CX-5 and the larger CX-9, offering a more premium and spacious option for families. This specific 2.5-liter gasoline engine paired with a six-speed automatic transmission occupied a central position in the CX-8 lineup, providing a balance of performance and fuel efficiency. It served as a mainstream offering, positioned below the diesel variants and above any potential base-level trims.

Powertrain & Engine Architecture
At the heart of the CX-8 2.5 SKYACTIV-G Automatic lies Mazda’s PY-VPS engine, a 2.5-liter inline-four cylinder gasoline engine. This engine is a cornerstone of Mazda’s SKYACTIV technology, emphasizing high compression (13:1) and optimized combustion for improved efficiency and power. The engine utilizes direct injection, contributing to precise fuel delivery and reduced emissions. The double overhead camshaft (DOHC) valvetrain, coupled with variable valve timing (VVT), further enhances engine responsiveness and performance across the rev range. The SKYACTIV-DRIVE six-speed automatic transmission is specifically tuned to complement the engine’s characteristics, offering smooth shifts and efficient power delivery. This transmission isn’t a traditional torque-converter automatic; it incorporates a quick-shifting design aimed at mimicking the feel of a dual-clutch transmission.
Driving Characteristics
The 192 horsepower and 258 Nm (190 lb-ft) of torque produced by this powertrain configuration delivers adequate, though not exhilarating, performance. Acceleration from 0 to 60 mph is estimated to be around 9-10 seconds. The SKYACTIV-DRIVE automatic transmission contributes to a relatively smooth driving experience, but it can sometimes feel hesitant during quick downshifts. Compared to the diesel variants of the CX-8, the 2.5-liter gasoline engine offers less low-end torque, requiring the transmission to downshift more frequently when climbing hills or overtaking. However, it provides a more linear power delivery and a generally quieter engine note. The gear ratios are optimized for fuel efficiency, prioritizing comfortable cruising over outright performance.
Equipment & Trim Levels
The CX-8 2.5 SKYACTIV-G Automatic typically came well-equipped, even in its base trim levels. Standard features often included automatic climate control, a touchscreen infotainment system with Bluetooth connectivity, power windows and locks, and a rearview camera. Higher trim levels added features such as leather upholstery, a sunroof, navigation system, and advanced safety technologies like lane departure warning and adaptive cruise control. Interior upholstery was generally cloth in lower trims, upgrading to leather in higher-spec models. Dashboard configurations were consistent across the range, featuring a clean and modern design aesthetic typical of Mazda vehicles.
Chassis & Braking
The CX-8 utilizes a front-engine, front-wheel-drive layout. Suspension consists of an independent McPherson strut setup at the front and an independent multi-link suspension at the rear, providing a comfortable ride and decent handling characteristics. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) is standard. The chassis is designed to balance ride comfort with handling stability, offering a composed driving experience for a vehicle of its size. Stabilizer bars are fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The Mazda CX-8 2.5 SKYACTIV-G Automatic was generally well-received by automotive critics, particularly for its spacious interior, comfortable ride, and stylish design. However, some reviewers noted that the engine could feel underpowered when fully loaded with passengers and luggage. Fuel economy was considered competitive for its class, averaging around 7.9 l/100 km (29.8 US mpg). Compared to the CX-8’s diesel variants, the gasoline engine offered lower running costs in terms of fuel price but sacrificed some low-end torque and fuel efficiency. Against competitors like the Toyota Kluger and Mitsubishi Outlander, the CX-8 distinguished itself with its more premium interior and engaging driving dynamics.
Legacy
The Mazda CX-8 2.5 SKYACTIV-G Automatic has proven to be a relatively reliable powertrain. The SKYACTIV engines are known for their durability, and the SKYACTIV-DRIVE transmission, while sometimes criticized for its responsiveness, has generally held up well over time. In the used car market, this variant represents a good value proposition, offering a spacious and well-equipped family SUV at a competitive price. Regular maintenance, including timely oil changes and transmission servicing, is crucial to ensure the long-term reliability of this powertrain. As of today, the CX-8 continues to be a popular choice in markets where it is offered, and the 2.5-liter SKYACTIV-G engine remains a key component of Mazda’s engine lineup.
