2021 Mazda CX-30 1.8 Skyactiv-D (130 Hp) Skyactiv-Drive

The Mazda CX-30 1.8 Skyactiv-D (130 hp) Skyactiv-Drive, introduced in January 2021, represents a diesel-powered variant within the first generation (CX-30) of Mazda’s compact crossover SUV. Positioned as a fuel-efficient option in the CX-30 lineup, it caters to European and Asian markets where diesel engines remain popular. This particular configuration combines a 1.8-liter four-cylinder diesel engine with Mazda’s proprietary Skyactiv-Drive six-speed automatic transmission. It aimed to provide a balance between economy, refinement, and everyday usability, slotting in as a mid-range offering below the more powerful petrol variants and above base models.

Technical Specifications

Powertrain & Engine Architecture

The heart of the CX-30 1.8 Skyactiv-D is Mazda’s S8-DPTS engine, a 1.8-liter inline-four cylinder diesel. This engine is a key component of Mazda’s Skyactiv technology, designed to maximize efficiency and reduce emissions. It features a high compression ratio of 14.8:1, achieved through careful engineering and precise fuel injection. The engine utilizes a common-rail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for optimal combustion. A turbocharger with an intercooler is employed to boost power and torque, providing 130 horsepower at 4000 rpm and 270 Nm (199 lb-ft) of torque between 1600 and 2600 rpm. The Skyactiv-Drive automatic transmission is a six-speed unit with a torque converter. Unlike traditional automatic transmissions, it’s programmed for quicker, more direct shifts, aiming to mimic the feel of a manual gearbox. It prioritizes fuel efficiency by utilizing a wider range of gear ratios and minimizing torque loss.

Driving Characteristics

The 1.8 Skyactiv-D with the Skyactiv-Drive automatic offers a comfortable and refined driving experience. While not a performance-oriented setup, the engine provides adequate power for everyday driving situations. Acceleration is linear, with the peak torque available from a relatively low 1600 rpm, making it responsive in city traffic and during overtaking maneuvers. The Skyactiv-Drive transmission contributes to smooth gear changes, although it can sometimes feel slightly hesitant during quick downshifts. Compared to the more powerful 2.0-liter petrol versions, the diesel offers significantly better fuel economy but lacks the same level of outright performance. The automatic transmission, while efficient, doesn’t provide the same level of driver engagement as the available six-speed manual gearbox. The weight of the vehicle (1460 kg) is noticeable, particularly when fully loaded.

Equipment & Trim Levels

The CX-30 1.8 Skyactiv-D Skyactiv-Drive typically came equipped with a respectable level of standard features. These generally included Mazda’s MZD Connect infotainment system with an 8.8-inch display, Bluetooth connectivity, and Apple CarPlay/Android Auto integration. Safety features such as lane departure warning, lane keep assist, and automatic emergency braking were also standard. Interior upholstery was typically cloth, with options for leather upgrades on higher trim levels. Available options included a sunroof, premium audio system, and adaptive cruise control. Trim levels varied by market, but generally offered increasing levels of luxury and technology.

Chassis & Braking

The CX-30 utilizes a front-wheel-drive platform with an independent McPherson strut suspension in the front and a torsion beam setup in the rear. This configuration provides a good balance between ride comfort and handling. The front brakes are ventilated discs, while the rear brakes are solid discs. The steering is an electric power-assisted rack and pinion system, offering light and precise steering feel. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The suspension tuning is geared towards comfort, but the CX-30 still offers a reasonably engaging driving experience.

Market Reception & Comparison

The Mazda CX-30 1.8 Skyactiv-D Skyactiv-Drive was generally well-received by automotive critics. It was praised for its fuel efficiency, refined engine, and comfortable ride. However, some reviewers noted that the engine could feel underpowered at times, particularly when carrying a full load or driving uphill. Compared to other diesel-powered crossovers in its class, the CX-30 offered a more premium interior and a more engaging driving experience. Its fuel economy was competitive, but not class-leading. Reliability reports have been generally positive, with few major issues reported with the engine or transmission.

Legacy

The 1.8 Skyactiv-D engine, coupled with the Skyactiv-Drive transmission, has proven to be a relatively reliable powertrain. While diesel engines are facing increasing scrutiny due to emissions regulations, the Skyactiv-D engine incorporates advanced technologies to minimize emissions and maximize efficiency. On the used car market, the CX-30 1.8 Skyactiv-D Skyactiv-Drive represents a sensible choice for buyers seeking a fuel-efficient and well-equipped compact crossover. Its reputation for reliability and Mazda’s overall build quality contribute to its continued appeal. Maintenance costs are generally reasonable, although diesel-specific components such as the particulate filter may require periodic servicing.
