Powertrain & Engine Architecture
At the heart of the 2018-2023 MX-5 2.0 Automatic lies Mazda’s PE-VPH 2.0-liter SkyActiv-G inline-four cylinder engine. This engine is characterized by its high compression ratio of 13:1, achieved through careful engineering and precise fuel injection. The direct injection system, coupled with a dual overhead camshaft (DOHC) valvetrain featuring variable valve timing (VVT), optimizes combustion efficiency and power delivery. The engine produces 181 horsepower at 7,000 rpm and 151.2 lb-ft of torque at 4,000 rpm. The six-speed automatic transmission, while not as engaging as the manual option, provides smooth shifts and enhances the car’s usability in everyday driving situations. It’s programmed for both efficiency and responsiveness, with paddle shifters available on some trim levels for more driver control.
Driving Characteristics
The 2.0-liter engine and automatic transmission combination delivers a respectable driving experience. While not as overtly sporty as the manual transmission version, the automatic provides a more relaxed and accessible driving style. Acceleration is brisk, and the engine is willing to rev, though it lacks the immediate response of the manual. The automatic transmission’s gear ratios are tuned to balance fuel economy and performance, providing adequate power for both city driving and highway cruising. Compared to the 1.5-liter engine, the 2.0-liter offers a noticeable increase in power and torque, making it more enjoyable for spirited driving. However, the automatic transmission does slightly diminish the overall sense of connection and control that the MX-5 is renowned for.
Equipment & Trim Levels
The 2018-2023 MX-5 2.0 Automatic typically came well-equipped, even in its base form. Standard features included a leather-wrapped steering wheel, a seven-inch Mazda Connect infotainment system with Bluetooth connectivity, a rearview camera, and automatic climate control. Higher trim levels, such as the Club, added features like heated leather seats, Bose premium audio, and advanced safety technologies like blind-spot monitoring and rear cross-traffic alert. Interior upholstery was generally cloth on the base models, with leather options available on higher trims. Optional extras included a retractable hardtop, keyless entry, and navigation.
Chassis & Braking
The ND MX-5 utilizes a lightweight chassis with a double-wishbone front suspension and an independent multi-link rear suspension. This setup provides excellent handling and a comfortable ride. The 2.0-liter models typically featured larger brakes than the 1.5-liter versions, with ventilated discs up front and solid discs in the rear. Anti-lock braking system (ABS) was standard. The car’s relatively low weight (around 2,388 lbs) contributes significantly to its agile handling characteristics. The electric power steering provides precise and responsive steering feel.
Market Reception & Comparison
The 2018-2023 MX-5 2.0 Automatic was generally well-received by automotive critics. It was praised for its engaging driving dynamics, stylish design, and overall value. However, some reviewers noted that the automatic transmission didn’t fully capture the spirit of the MX-5, and preferred the more involving experience of the manual gearbox. Fuel economy was considered good for a sports car, averaging around 26 mpg in the city and 35 mpg on the highway. Compared to the 1.5-liter automatic, the 2.0-liter offered a significant performance upgrade, while the manual 2.0-liter provided the most engaging driving experience. Reliability was generally high, with few reported issues.
Legacy
The 2018-2023 Mazda MX-5 2.0 SkyActiv-G Automatic has established itself as a reliable and enjoyable sports car in the used car market. The SkyActiv engine has proven to be durable, and the automatic transmission, while not the first choice for enthusiasts, has demonstrated good longevity. These models continue to be popular among those seeking an affordable and fun-to-drive roadster. The ND MX-5, in general, has solidified the MX-5’s reputation as one of the best driver’s cars available, and the 2.0-liter automatic variant offers a compelling option for those who prioritize convenience and ease of use alongside the MX-5’s inherent charm.
