2018 Mazda MX-5 IV (RF) 1.5 SkyActiv-G (132 Hp)

The Mazda MX-5 RF 1.5 SkyActiv-G (132 hp) is a rear-wheel drive, two-seat sports car produced by Mazda beginning in August 2018. It represents a key variant within the fourth generation (ND) MX-5 lineup, specifically the Retractable Fastback (RF) body style. Positioned as an entry-level offering within the RF range, it provided a more accessible price point compared to the higher-output 2.0-liter models, while still delivering the core MX-5 driving experience. The RF variant distinguishes itself from the soft-top MX-5 with its power-retracting hardtop, offering increased security and all-weather usability.

Technical Specifications

INTRODUCTION

The MX-5 RF 1.5 SkyActiv-G represents Mazda’s continued commitment to the lightweight, affordable roadster formula. Introduced as part of the ND generation’s mid-cycle refresh, it offered a compelling alternative to the soft-top version, particularly for buyers seeking a more refined and secure driving experience. The “RF” designation stands for “Retractable Fastback,” highlighting the car’s unique power-folding hardtop. This variant aimed to broaden the MX-5’s appeal without sacrificing the core driving dynamics that have defined the model for decades. It slotted into the lineup as the more economical option, appealing to drivers prioritizing fuel efficiency and a lower purchase price over outright performance.

Powertrain & Engine Architecture

At the heart of the MX-5 RF 1.5 is the SkyActiv-G 1.5-liter inline-four cylinder engine. This engine, designated as the PE-VPH, is a naturally aspirated powerplant known for its responsiveness and efficiency. It utilizes direct injection, a high compression ratio of 13:1, and a double overhead camshaft (DOHC) valvetrain to maximize power output and fuel economy. The engine produces 132 horsepower at 7,000 rpm and 152 Nm (112 lb-ft) of torque at 4,500 rpm. The 1.5-liter engine differs from the 2.0-liter SkyActiv-G found in other ND MX-5 variants, offering a slightly less aggressive power delivery. The engine is longitudinally mounted, driving the rear wheels. The standard transmission for this variant is a six-speed manual, though a six-speed automatic transmission was also available. The automatic transmission is a conventional torque-converter type, tuned for smooth shifts and fuel efficiency rather than outright performance.

Driving Characteristics

The MX-5 RF 1.5 SkyActiv-G delivers a characteristically engaging driving experience, albeit with a slightly more relaxed demeanor than its 2.0-liter siblings. The 132 hp engine provides adequate power for spirited driving, but it requires more frequent downshifts to maintain momentum, especially when tackling hills or overtaking. The six-speed manual transmission offers precise shifts and a direct connection to the engine, enhancing driver involvement. The automatic transmission, while smooth, can feel somewhat hesitant and less responsive. The car’s lightweight construction (approximately 1038 kg / 2288 lbs) contributes to its nimble handling and responsive steering. The rear-wheel drive layout provides a balanced chassis and predictable handling characteristics. The suspension is tuned for a balance between comfort and control, offering a compliant ride on most road surfaces.

Equipment & Trim Levels

The MX-5 RF 1.5 SkyActiv-G typically came equipped with a respectable level of standard features. These included power windows and locks, air conditioning, a leather-wrapped steering wheel, and a basic infotainment system with a 7-inch touchscreen display. Safety features such as ABS, stability control, and multiple airbags were also standard. Optional extras included a Bose premium audio system, heated seats, keyless entry, and a rearview camera. Interior upholstery was typically cloth, with leather options available as an upgrade. Trim levels varied slightly depending on the market, but generally offered packages that added convenience and aesthetic enhancements.

Chassis & Braking

The MX-5 RF utilizes a double wishbone suspension setup at the front and an independent multi-link suspension at the rear, both incorporating a stabilizer bar to reduce body roll. This suspension configuration provides a good balance of ride comfort and handling precision. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is assisted by ABS (Anti-lock Braking System) and electronic brake-force distribution. The relatively low weight of the vehicle contributes to its effective braking performance.

Market Reception & Comparison

The MX-5 RF 1.5 SkyActiv-G was generally well-received by automotive critics. It was praised for its engaging driving dynamics, stylish design, and fuel efficiency. However, some reviewers noted that the 1.5-liter engine lacked the punch of the 2.0-liter variant, particularly for drivers seeking a more exhilarating driving experience. Compared to the 2.0-liter MX-5 RF, the 1.5-liter model offered better fuel economy (around 6.3 l/100km combined) and a lower price point, making it a more accessible option for budget-conscious buyers. The automatic transmission was often criticized for its lack of responsiveness compared to the manual.

Legacy

The Mazda MX-5 RF 1.5 SkyActiv-G has proven to be a reliable and enjoyable sports car. The SkyActiv-G engine is known for its durability and relatively low maintenance costs. The powertrain, while not the most powerful, is generally considered to be robust and long-lasting. On the used car market, these models hold their value reasonably well, particularly those in good condition with low mileage. The RF’s retractable hardtop adds to its appeal, providing a more secure and weather-resistant alternative to the soft-top MX-5. It remains a popular choice for enthusiasts seeking an affordable and engaging roadster experience.
