2015-2017 Mazda 6 III Sedan (GJ facelift ) 2.2 SKYACTIV-D (150 Hp) i-ELOOP

The Mazda 6 III Sedan, specifically the facelifted model produced from 2015 to 2017, represented a significant evolution of Mazda’s mid-size offering. Within the GJ generation, the 2.2 SKYACTIV-D variant with 150 horsepower and i-ELOOP technology occupied a key position, balancing fuel efficiency with respectable performance. This model aimed to appeal to drivers seeking a refined and economical driving experience in the competitive D-segment. The i-ELOOP system, a kinetic energy recovery system, further enhanced the car’s fuel-saving capabilities, making it a noteworthy contender in the diesel sedan market.

Technical Specifications

INTRODUCTION

The Mazda 6 III Sedan (GJ) facelift, launched in 2015, represented a refinement of the already successful third-generation Mazda 6. This update brought styling tweaks, improved interior materials, and enhancements to the car’s already impressive SKYACTIV technology. The 2.2 SKYACTIV-D 150 hp variant, equipped with the i-ELOOP regenerative braking system, was a key offering in many European and Asian markets. Positioned as a mid-range option, it provided a balance between performance, fuel economy, and equipment levels, appealing to buyers prioritizing efficiency and comfort. It sat below the more powerful 2.2 SKYACTIV-D 175 hp version and above the lower-powered 2.0-liter gasoline options.

Powertrain & Engine Architecture

At the heart of this Mazda 6 variant lies the SHY4 2.2-liter four-cylinder diesel engine. This engine is a cornerstone of Mazda’s SKYACTIV technology, designed to maximize efficiency and minimize emissions. The SHY4 utilizes a high compression ratio of 14:1, contributing to its thermal efficiency. It features a twin-turbocharger setup – a small turbo for quick response at low engine speeds and a larger turbo for sustained power at higher RPMs. Direct injection, utilizing a common rail system, ensures precise fuel delivery. The i-ELOOP system, a capacitor-based regenerative braking system, recovers kinetic energy during deceleration and stores it to power electrical components, reducing the load on the alternator and improving fuel economy. The engine is transversely mounted at the front of the vehicle. The 6-speed manual transmission was standard, offering precise shifts and contributing to the car’s engaging driving experience.

Driving Characteristics

The 150 hp SKYACTIV-D engine, coupled with the 6-speed manual transmission, provided a smooth and refined driving experience. While not overtly sporty, it offered ample torque – 380 Nm (280 lb-ft) – available from a low 1800 rpm, making it well-suited for everyday driving and overtaking maneuvers. The gear ratios were well-chosen, providing good acceleration in each gear. Compared to the 175 hp version, the 150 hp model felt slightly less urgent, particularly at higher speeds, but the difference was not dramatic. The manual transmission allowed for greater driver control, while the i-ELOOP system was largely transparent to the driver, working silently in the background to improve fuel efficiency. The car’s suspension provided a comfortable ride, absorbing bumps and imperfections in the road surface effectively.

Equipment & Trim Levels

The 2.2 SKYACTIV-D 150 hp variant typically came equipped with a generous level of standard features. These included air conditioning, power windows and mirrors, a touchscreen infotainment system with Bluetooth connectivity, and alloy wheels. Higher trim levels added features such as leather upholstery, a sunroof, a premium sound system, and advanced safety technologies like lane departure warning and adaptive cruise control. Interior upholstery was typically cloth on the base trims, with leather options available on higher-spec models. Dashboard configuration was consistent across the range, featuring a clean and modern design with intuitive controls.

Chassis & Braking

The Mazda 6 III Sedan utilized a front-wheel-drive layout with a MacPherson strut front suspension and a multi-link rear suspension. This setup provided a good balance between ride comfort and handling. The braking system consisted of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. Anti-lock Braking System (ABS) was standard, enhancing safety during emergency braking situations. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The Mazda 6 III Sedan, and particularly the 2.2 SKYACTIV-D 150 hp variant, received positive reviews from automotive critics. It was praised for its stylish design, refined interior, and excellent fuel economy. Compared to its rivals, such as the Ford Mondeo and Volkswagen Passat, the Mazda 6 offered a more engaging driving experience and a more premium feel. The 150 hp diesel engine provided a good balance between performance and efficiency, making it a popular choice for drivers covering long distances. The i-ELOOP system was also well-received, contributing to the car’s impressive fuel consumption figures. However, some critics noted that the rear passenger space was slightly less generous than some of its competitors.

Legacy

The SHY4 2.2 SKYACTIV-D engine has proven to be a reliable and durable powertrain. While diesel engines, in general, have faced increased scrutiny in recent years, the SKYACTIV-D engines have a relatively good reputation for longevity, provided they are properly maintained. On the used car market, the Mazda 6 III Sedan 2.2 SKYACTIV-D 150 hp variant remains a popular choice, offering a compelling combination of style, comfort, and fuel efficiency. Regular servicing, including oil changes and filter replacements, is crucial to maintaining the engine’s performance and reliability. The i-ELOOP system has also proven to be durable, with few reported issues.
