The Mazda MX-5 RF 1.5 SkyActiv-G (131 hp) is a rear-wheel drive, two-seat sports car produced by Mazda between January 2017 and August 2018. It represents a significant iteration of the fourth-generation MX-5 (ND), distinguished by its retractable fastback (RF) hardtop. This variant occupied the entry-level position in the RF lineup, offering a balance of affordability and the MX-5’s signature driving experience. It was primarily marketed in Europe and Asia, where smaller, fuel-efficient sports cars are highly valued, though limited numbers were also available in North America.

Powertrain & Engine Architecture
The MX-5 RF 1.5 SkyActiv-G utilizes Mazda’s PE-VPH engine code, a 1.5-liter inline-four cylinder naturally aspirated engine. This engine is a key component of Mazda’s SkyActiv technology suite, designed to maximize efficiency and responsiveness. It features direct injection, a high compression ratio of 13:1, and a lightweight design. The valvetrain employs a dual overhead camshaft (DOHC) configuration with four valves per cylinder. The engine’s output of 131 horsepower at 7000 rpm and 150 Nm (110.63 lb-ft) of torque at 4800 rpm is achieved without the aid of turbocharging, relying instead on optimized combustion and airflow. The engine is longitudinally mounted, driving the rear wheels. The transmission is a six-speed manual, contributing to the car’s sporty character.
Driving Characteristics
The 1.5-liter engine, paired with the six-speed manual transmission, provides a lively, though not overwhelming, driving experience. Acceleration from 0-60 mph takes approximately 8.2 seconds, and the car reaches a top speed of 126.14 mph. The engine’s power delivery is linear, requiring the driver to utilize the full rev range to extract maximum performance. Compared to the 2.0-liter variants, the 1.5L feels less potent, particularly during overtaking maneuvers. However, its lighter weight contributes to nimble handling and a more balanced feel. The gear ratios are well-matched to the engine’s characteristics, allowing for spirited driving on winding roads. The RF’s retractable hardtop adds a degree of refinement and sound insulation compared to the soft-top MX-5, but also slightly increases the vehicle’s weight.
Equipment & Trim Levels
The 1.5 SkyActiv-G RF typically came equipped with standard features such as air conditioning, power windows and locks, a leather-wrapped steering wheel, and a basic infotainment system with a 7-inch display screen. Safety features included ABS, stability control, and multiple airbags. Interior upholstery was typically cloth, though leather options were available. Optional extras included a Bose premium audio system, navigation system, heated seats, and keyless entry. The trim level generally sat as the base model for the RF, offering a more accessible entry point into the MX-5 RF range.
Chassis & Braking
The MX-5 RF utilizes a lightweight chassis with a double wishbone front suspension and an independent multi-link rear suspension. This setup provides excellent handling and ride quality. The car features ventilated disc brakes at the front and solid disc brakes at the rear. ABS (Anti-lock Braking System) is standard. The relatively low curb weight of 1015 kg (2237.69 lbs) contributes significantly to the car’s agility. The suspension is tuned for a sporty driving experience, offering a firm but controlled ride.
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 outright power of the 2.0-liter variants. Compared to the 2.0-liter MX-5 RF, the 1.5L offered better fuel economy (6.1 l/100 km combined) and a lower price point, making it an attractive option for budget-conscious buyers. The 1.5L was also seen as a more accessible entry point for those new to the MX-5 experience.
Legacy
The PE-VPH engine, while not as powerful as its 2.0-liter counterpart, has proven to be a reliable and durable powertrain. The SkyActiv technology employed in the engine contributes to its longevity. In the used car market, the MX-5 RF 1.5 SkyActiv-G remains a popular choice for those seeking an affordable and fun-to-drive sports car. Maintenance costs are generally reasonable, and parts availability is good. The RF’s retractable hardtop adds a degree of practicality and security that appeals to many buyers, ensuring its continued desirability in the years to come.
