INTRODUCTION
The 2018 facelift of the Mazda MX-5 ND brought with it subtle but important revisions to the exterior styling, interior refinement, and powertrain. The 2.0-liter SkyActiv-G engine, producing 184 hp, became the flagship offering, replacing the earlier 167 hp version. This engine was a key component of Mazda’s SkyActiv technology suite, designed to maximize efficiency and responsiveness. The ND generation, built on the 1HX0 platform, aimed to recapture the spirit of the original NA Miata – lightweight, balanced, and focused on the driving experience. This variant was primarily sold in North America, Europe, and Japan, catering to enthusiasts seeking an affordable and engaging sports car.
Powertrain & Engine Architecture
The heart of this MX-5 variant is the PE-VPH engine, a 1998cc (121.93 cu. in.) inline-four cylinder engine utilizing Mazda’s SkyActiv technology. This includes direct injection, a high compression ratio of 13:1, and a lightweight design. The engine employs a DOHC-VVT (Dual Overhead Camshaft, Variable Valve Timing) system to optimize performance across the rev range. The fuel injection system is a multi-hole piezo injector, ensuring precise fuel delivery. The engine’s architecture prioritizes thermal efficiency, contributing to improved fuel economy. The 6-speed manual transmission, standard on this model, features closely spaced ratios designed to keep the engine in its powerband. The transmission is known for its precise shift feel and contributes significantly to the car’s engaging driving dynamics.
Driving Characteristics
The 184 hp 2.0-liter engine, coupled with the lightweight chassis (approximately 2260 lbs), delivers a spirited driving experience. Acceleration from 0-60 mph takes around 6.2 seconds, and the car feels noticeably quicker than the earlier 1.5-liter models. The engine’s torque curve is relatively flat, providing usable power throughout the rev range, although peak torque of 151.2 lb-ft is available at 4000 rpm. The manual transmission’s short throws and precise engagement enhance driver involvement. Compared to the 1.5-liter engine, the 2.0-liter offers more substantial mid-range punch, making overtaking maneuvers easier and more confident. While not a high-horsepower machine, the MX-5’s balanced chassis and responsive engine make it a joy to drive on winding roads.
Equipment & Trim Levels
The 2.0-liter MX-5 typically came well-equipped, though specific features varied by market. Standard equipment generally included a leather-wrapped steering wheel, air conditioning, power windows and locks, and a basic audio system. Higher trim levels, such as the Club and Grand Touring (in the US market), added features like heated seats, a Bose premium audio system, automatic climate control, and advanced safety features like blind-spot monitoring and rear cross-traffic alert. Interior upholstery was typically cloth on the base model, with leather options available on higher trims. Optional extras included a retractable hardtop, Bilstein dampers, and Recaro seats.
Chassis & Braking
The ND MX-5 utilizes a double-wishbone front suspension and an independent multi-link rear suspension, contributing to its excellent handling characteristics. The suspension is tuned for a balance between comfort and responsiveness. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) is standard. The car’s relatively low weight minimizes the need for overly aggressive braking components. The steering is a rack-and-pinion system with electric power assistance, providing precise and communicative steering feel.
Market Reception & Comparison
The 2018 facelifted MX-5 2.0 SkyActiv-G was generally well-received by automotive critics. It was praised for its engaging driving dynamics, responsive engine, and stylish design. Compared to the 1.5-liter model, the 2.0-liter was seen as a more complete package for enthusiasts, offering a more satisfying driving experience. Fuel economy was also considered respectable, averaging around 34.1 US mpg in combined driving. Reliability has been generally good, with few widespread issues reported. Compared to competitors like the Fiat 124 Spider (which shared the MX-5’s platform but used a different engine), the Mazda was often favored for its more refined engine and overall driving experience.
Legacy
The ND MX-5, and particularly the 2.0-liter variant, has cemented its position as a modern classic. The SkyActiv engine has proven to be durable and reliable, and the car’s simple yet effective design makes it relatively easy to maintain. On the used car market, these models hold their value well, reflecting their popularity and desirability. The ND MX-5 continues to be a benchmark for affordable, lightweight sports cars, and the 2.0-liter version remains a particularly sought-after choice for driving enthusiasts.
