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

The Mazda MX-5 RF (Retractable Fastback) 2.0 SkyActiv-G, producing 181 horsepower, represents a compelling blend of performance and open-air driving enjoyment within the fourth generation (ND) MX-5 lineup. Introduced in August 2018, this variant builds upon the success of the ND platform – first launched in 2015 – offering a more refined and weather-protected experience compared to the soft-top version. The RF model distinguishes itself with a power-retractable hardtop, adding a touch of sophistication and security while maintaining the MX-5’s core focus on lightweight agility. This particular engine and transmission combination occupied a mid-range position within the ND MX-5 family, offering a step up in performance from the base 1.5-liter engine while remaining accessible to a broader range of buyers.

Technical Specifications

Powertrain & Engine Architecture

At the heart of the MX-5 RF 2.0 SkyActiv-G lies Mazda’s PE-VPH engine, a 1998cc naturally aspirated inline-four cylinder. This engine is a cornerstone of Mazda’s SkyActiv technology, emphasizing efficiency and responsiveness. Key features include a high compression ratio of 13:1, direct injection, and a sophisticated dual overhead camshaft (DOHC) valvetrain with variable valve timing (VVT). The engine’s design prioritizes torque delivery across a broad rev range, contributing to its engaging driving experience. The 181 horsepower and 151.2 lb.-ft. of torque are respectable figures for a small displacement engine, and are achieved without the aid of turbocharging. The engine utilizes a conventional wet-sump lubrication system with a 4.3-liter oil capacity. The six-speed manual transmission, standard on this model, features closely spaced ratios designed to keep the engine within its optimal power band.

Driving Characteristics

The 2.0-liter engine paired with the six-speed manual transmission delivers a balanced and engaging driving experience. Acceleration from 0-60 mph takes approximately 6.5 seconds, making it a sprightly performer. The engine is eager to rev, and the manual gearbox provides precise and satisfying shifts. Compared to the 1.5-liter MX-5, the 2.0-liter offers noticeably more power and torque, particularly in the mid-range, making overtaking and climbing hills less of a strain. While not as brutally fast as some turbocharged sports cars, the MX-5 RF 2.0 prioritizes driver involvement and a connected feel. The relatively lightweight construction (around 2363 lbs) contributes to its nimble handling and responsive steering. The gear ratios are well-matched to the engine’s power curve, allowing for strong acceleration in each gear.

Equipment & Trim Levels

The MX-5 RF 2.0 SkyActiv-G typically came well-equipped, though specific features varied depending on optional packages. Standard equipment generally included leather upholstery, a 7-inch touchscreen infotainment system with Mazda Connect, Bluetooth connectivity, a rearview camera, and automatic climate control. Available options included a premium Bose audio system, navigation, adaptive front lighting, and safety features like blind spot monitoring and rear cross-traffic alert. The RF model also featured a power-retractable hardtop as standard, offering a more refined and secure driving experience compared to the soft-top version. Interior trim options were relatively limited, typically focusing on black leather with contrasting stitching.

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’s low center of gravity further enhances its agility. Braking duties are handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. Anti-lock braking system (ABS) is standard. The RF model’s slightly increased weight compared to the soft-top version necessitates a slightly firmer suspension tuning to maintain the same level of handling performance.

Market Reception & Comparison

The Mazda MX-5 RF 2.0 SkyActiv-G was generally well-received by automotive critics. It was praised for its engaging driving dynamics, refined interior, and the added convenience of the retractable hardtop. Compared to the 1.5-liter MX-5, the 2.0-liter offered a more satisfying driving experience for those who prioritized performance. Fuel economy was respectable, averaging around 34.1 US mpg in combined driving. Reliability has been generally good, with the SkyActiv engine proving to be durable and relatively maintenance-free. Some critics noted that the RF’s hardtop added weight and slightly diminished the open-air experience compared to the soft-top version, but the added refinement and security were seen as worthwhile trade-offs by many buyers.

Legacy

The MX-5 RF 2.0 SkyActiv-G has established itself as a desirable used sports car. Its combination of performance, reliability, and affordability makes it an attractive option for enthusiasts. The SkyActiv engine has proven to be durable, and maintenance costs are generally reasonable. The RF model’s retractable hardtop adds a layer of practicality and security that appeals to a wider range of buyers. As the fourth-generation MX-5 continues to age, the RF 2.0 SkyActiv-G is likely to remain a popular choice for those seeking a fun-to-drive and well-engineered sports car.
