The Mazda MX-5 RF 2.0 SkyActiv-G (160 hp) Automatic, produced from April 2015 to August 2018, represents a compelling blend of sporty handling and open-air enjoyment within the fourth generation (ND) of Mazda’s iconic roadster. The “RF” designation stands for “Retractable Fastback,” distinguishing it from the soft-top MX-5. This variant occupied a mid-range position in the ND lineup, offering a more refined and convenient top mechanism compared to the standard soft-top, while providing a more accessible entry point to the 2.0-liter engine option than the Club or Grand Touring trims. It was primarily marketed towards drivers seeking a stylish, engaging sports car experience with the added comfort of a power-retractable hardtop.

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 cornerstone of Mazda’s efficiency-focused engineering philosophy. It features a high compression ratio of 13:1, achieved through careful design and precise combustion control. Direct injection is employed to optimize fuel delivery and enhance thermal efficiency. The engine utilizes a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its responsive nature. The engine’s output of 160 horsepower at 6000 rpm and 147.51 lb-ft of torque at 4600 rpm is respectable for its displacement, but not the highest in the ND MX-5 range. The six-speed automatic transmission, while offering convenience, is a traditional torque-converter type, differing from the more modern dual-clutch transmissions found in some competitors.
Driving Characteristics
The 2.0-liter engine paired with the six-speed automatic transmission delivers a smooth, if not overtly thrilling, driving experience. Compared to the six-speed manual version, the automatic sacrifices some of the driver engagement and immediacy. The automatic transmission’s gear ratios are tuned for fuel efficiency and comfortable cruising, rather than aggressive acceleration. While the transmission offers a “Sport” mode for more responsive shifts, it doesn’t fully replicate the control offered by the manual gearbox. Acceleration from 0-60 mph takes approximately 8.1 seconds, which is slower than the manual variant. However, the automatic provides a more relaxed driving experience, particularly in urban traffic. The RF’s retractable hardtop adds some weight compared to the soft-top, slightly impacting handling agility, but the difference is minimal.
Equipment & Trim Levels
The MX-5 RF 2.0 Automatic typically came equipped with standard features such as leather upholstery, a seven-inch touchscreen infotainment system with Mazda Connect, Bluetooth connectivity, a rearview camera, and automatic climate control. Additional features often included heated seats, a premium Bose audio system, and advanced safety technologies like lane departure warning and adaptive front lighting. The RF’s retractable hardtop was, of course, the defining feature of this variant, offering improved security and weather protection compared to the soft-top. Optional extras included keyless entry and ignition, and various cosmetic enhancements.
Chassis & Braking
The MX-5 RF utilizes a lightweight chassis with a MacPherson strut front suspension and a multi-link rear suspension. The suspension is tuned for a balance of comfort and handling, providing a relatively compliant ride while maintaining good body control. The RF 2.0 Automatic is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) is standard. The relatively low curb weight (around 2370-2460 lbs) contributes to the car’s nimble handling characteristics.
Market Reception & Comparison
The MX-5 RF 2.0 Automatic was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and engaging driving experience. However, some reviewers noted that the automatic transmission detracted from the overall sporty feel of the car. Compared to the 1.5-liter engine option, the 2.0-liter provided noticeably more power and torque, making it a better choice for drivers who prioritize performance. Compared to the manual transmission version, the automatic offered greater convenience but less driver involvement. Fuel economy was competitive for its class, averaging around 36.8 US mpg in combined driving.
Legacy
The Mazda MX-5 RF 2.0 SkyActiv-G Automatic 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 automatic transmission, while not as engaging as the manual, has also proven to be dependable. On the used car market, these models hold their value reasonably well, reflecting the MX-5’s enduring popularity and reputation for quality. The RF’s retractable hardtop adds to its appeal, making it a practical and stylish choice for drivers who want a sports car they can enjoy year-round.
