2018 Mazda MX-5 IV (RF) 2.0 SkyActiv-G (181 Hp) Automatic

The Mazda MX-5 RF 2.0 SkyActiv-G (181 hp) Automatic, introduced in August 2018, represents a compelling blend of performance and accessibility within the fourth generation (ND) MX-5 lineup. The “RF” designation stands for “Retractable Fastback,” distinguishing it from the soft-top convertible version. This variant occupied a mid-range position in the ND MX-5 family, offering a step up in power and refinement compared to the base 1.5-liter models, while remaining more attainable than the limited-edition or Club trims. It’s built on the ND platform, known for its lightweight design and focus on driver engagement, and was primarily marketed towards enthusiasts seeking a sporty, open-air experience with the convenience of an automatic transmission.

Technical Specifications

Powertrain & Engine Architecture

At the heart of the MX-5 RF 2.0 Automatic lies Mazda’s PE-VPH 2.0-liter SkyActiv-G inline-four cylinder engine. This engine is a key component of Mazda’s SkyActiv technology suite, designed to maximize efficiency and performance. It features direct injection, a high compression ratio of 13:1, and a sophisticated dual overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) on both intake and exhaust sides. The engine produces 181 horsepower at 7,000 rpm and 151.2 lb-ft of torque at 4,000 rpm. The SkyActiv-G engine prioritizes torque delivery across a broad rev range, making it responsive in everyday driving situations. Paired with the engine is a six-speed automatic transmission with manual shift mode. This transmission was specifically tuned to complement the engine’s characteristics, offering smooth shifts and efficient operation. While not as engaging as the available six-speed manual, the automatic provides a more accessible driving experience for a wider range of drivers.

Driving Characteristics

The MX-5 RF 2.0 Automatic delivers a driving experience that emphasizes balance and agility. The relatively low curb weight of 2,493 lbs contributes to its nimble handling. The automatic transmission, while smooth, does slightly diminish the sense of direct control compared to the manual version. Gear ratios are optimized for both acceleration and fuel efficiency. In typical driving conditions, the transmission shifts promptly and predictably. However, some drivers may find the automatic’s shift points less aggressive than desired during spirited driving. The rear-wheel-drive layout and well-tuned suspension provide excellent cornering stability and a connected feel to the road. The power delivery is linear and predictable, making it easy to modulate throttle and maintain control. Compared to the 1.5-liter MX-5, the 2.0-liter engine provides noticeably more power and torque, resulting in quicker acceleration and more confident passing maneuvers.

Equipment & Trim Levels

The MX-5 RF 2.0 Automatic typically came equipped with a generous array of standard features. These included leather upholstery, a 7-inch touchscreen infotainment system with Mazda Connect, Bluetooth connectivity, a rearview camera, and automatic climate control. Safety features such as ABS, stability control, and multiple airbags were also standard. Optional extras included a premium Bose audio system, heated seats, and advanced safety technologies like blind spot monitoring and rear cross-traffic alert. The RF model also featured a power-retractable hardtop, providing the security and weather protection of a coupe with the open-air enjoyment of a convertible. Interior trim levels varied, with options for different color schemes and materials.

Chassis & Braking

The MX-5 RF utilizes a lightweight chassis construction, employing high-strength steel in key areas to maximize rigidity while minimizing weight. The front suspension features a double wishbone design, while the rear utilizes an independent multi-link setup. This configuration provides excellent ride quality and handling precision. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is equipped with ABS to prevent wheel lockup during hard braking. The steering system is a rack-and-pinion setup with electric power assistance, providing precise and responsive steering feel. The relatively low ride height and optimized suspension geometry contribute to the car’s sporty handling characteristics.

Market Reception & Comparison

The MX-5 RF 2.0 Automatic was generally well-received by automotive critics. Reviewers praised its engaging driving dynamics, stylish design, and refined interior. The automatic transmission was noted as a convenient option for drivers who preferred not to operate a manual gearbox. However, some critics felt that the automatic slightly detracted from the overall driving experience. Compared to the 1.5-liter MX-5, the 2.0-liter version offered a significant performance upgrade, making it a more appealing choice for enthusiasts. Fuel economy was respectable, with EPA estimates around 26 mpg city and 35 mpg highway. Reliability has been generally good, with few widespread issues reported.

Legacy

The Mazda MX-5 RF 2.0 SkyActiv-G Automatic has established itself as a popular choice in the used car market. Its combination of sporty handling, stylish design, and relative reliability has made it a desirable option for enthusiasts and casual drivers alike. The SkyActiv-G engine has proven to be durable and efficient, with proper maintenance. The automatic transmission, while not as engaging as the manual, has proven to be reliable.
