Since its introduction in 1989, the MX-5 Miata has become one of the most recognizable convertible sports cars. Although many competitors have come and gone in the past 30 years, only the MX-5 has endured. Through four generations, Mazda developed the MX-5 into a remarkably polished sports car.
Mazda sells the Miata as a cloth-top convertible and the RF (Retractable Fastback), a clever power retractable targa top. Although we tested a 2022 MX-5, pricing noted is for the 2023 model year vehicles. Starting at $28,050, the base Sport and midlevel Club ($31,550) slot below the Grand Touring ($33,050). The Miata RF skips the Sport trim and is offered in Club ($38,550) and Grand Touring ($35,350) models. Our test vehicle was a 2022 MX-5 Club optioned with machine gray paint ($595) and Brembo BBS Recaro package ($4,500). The total added up to $36,910 including the $1,015 delivery fee. Significant standard and optional equipment consist of LED headlights, Bose 9-speaker audio system, Apple CarPlay, Android Auto, BBS 17-in. alloy wheels, shock tower brace, heated Recaro cloth seats, 7-in. touchscreen display, rearview camera, 6-speed manual gearbox and torque-sensing limited-slip differential. Active safety technologies include blind-spot monitoring, rear cross-traffic alert and lane departure warning.
Mazda's all-aluminum Skyactiv-G 2.0L inline-4 powers all Miatas, but is tuned for more power than the 155-hp it cranks out in the Mazda3. In the MX-5, the dual overhead-can 2.0L is rated at 181-hp @ 7,000 RPM and 151 lb.-ft. @ 4,000 RPM. Transmission choices consist of a 6-speed manual or an optional automatic. The manual gearbox is a close-ratio unit with a 1.000:1 sixth gear coupled to a 2.866:1 final drive ratio. EPA fuel consumption estimates for the 6-speed manual are 26/34 MPG (city/hwy.). Opting for the automatic transmission raises the highway rating to 35 MPG. We averaged just under 35-38 MPG in mixed city and highway driving in our 6-speed manual test vehicle.
The Miata's front suspension design consists of double wishbones, coil springs, dampers, and stabilizer bar. At the rear is a multi-link layout with coil springs, dampers, and stabilizer bar. Bilstein dampers, sport-tuned suspension and a torque-sensing limited-slip differential are included with the 6-speed manual. Brakes are all-discs: 11.0-in. dia. front and rear rotors (Brembo brakes in front). The MX-5 Club gets black BBS alloy wheels (17" in. dia.) and P205/45R17 Bridgestone S001 summer performance tires. Steering is a rack-and-pinion setup with electric power assist geared for 2.7 turns lock-to-lock. Curb weight is an exceptionally light 2,341 lbs. (manual transmission) or 2,403 lbs. (automatic transmission).
Mazda continued its tradition of designing a compact cockpit for the Miata. Anyone taller than 6 ft. will consider the interior confining and cramped, especially with the cloth top up. The instrument cluster consists of a central tachometer, flanked by a speedometer to the right and a multi-function display on the opposite side. Coolant temperature and fuel level are shown via digital bar graph gauges on the multi-function display. The leather-wrapped steering wheel has integrated controls for phone, audio, cruise, and the vehicle status. Mounted on the dash is the 7-in. infotainment touchscreen (navigation is available via CarPlay or Android Auto) and audio functions. Climate controls knobs are mounted on the center stack within easy reach. Dual USB ports allow charging and audio input for mobile devices. A 12V power outlet is hidden under the dash in the passenger footwell. Infotainment system control knobs are on the center console next to the driver's seat. Mazda's engineers were unconcerned about cupholders: the driver's cupholder is between the seats, essentially unusable while driving. The passenger cupholder is cantilevered off the center console in the footwell.
The Miata's compact cockpit suits passengers with slimmer builds; larger occupants will barely fit. Optional Recaro sport seats, covered in a suede-like cloth and vinyl, are a significant upgrade from the standard seats. The Recaros offer power height adjustability that the standard seats lack. The trunk compartment is small, shallow, and best suited for soft luggage. A rolling carry-on suitcase will fit, but leaves room for little else.
A rigid chassis is the greatest contributor to the MX-5's much improved handling. Cowl shake, body shudder over bumps, and squeaks and rattles are mostly suppressed, but bumpy roads reveal some chassis minor flex. As enthusiasts familiar with this roadster know, it's not about maximum g-force, but the quick turn-in response and nimble reflexes that set the MX-5 apart from any other competitor. Crank the steering wheel, and the MX-5 obediently follows the intended arc. Understeer in almost nonexistent, but mild power-on oversteer is a distinct possibility in 1st or 2nd gear. Steering feel is superb; the driver seems almost directly connected to the road. Although the short 90.9-in. wheelbase and firm suspension tuning contribute to razor-sharp handling, a jittery ride on patched concrete surfaces is an unavoidable consequence.
Mazda's Skyactiv-G 2.0L is surprisingly buzzy engine, considering its small displacement. At cold idle, vibrations envelope the entire body structure, but subside as the engine warms up. A convertible's less rigid body structure undoubtedly amplifies engine vibrations. Throttle response is linear up to the 7,500 RPM redline. Throttle response below 2,000 RPM is minimal, so keeping revs near the 4,000 RPM torque peak is essential. However, the Miata's low curb weight contributes to sprightly acceleration; redlining the engine was rarely necessary even in spirited driving.
A short-throw lever, topped by a leather-wrapped aluminum knob connects to the standard 6-speed manual driving the rear wheels. This close-ratio gearbox has the perfect ratios for winding two-lane roads; shift gates are closely spaced, but there is just enough "notchiness" to select the correct gear. A moderately heavy, progressive clutch assists with smooth shifts. Braking performance is superb, no doubt due to the Brembos that contribute to firm, progressive pedal actuation. The 2.0L inline-4 revs over 4,000 RPM above 70 MPH, due to the non-overdrive sixth gear. For relaxed highway cruising, the automatic and its taller (numerically lower) overdrive ratios is our recommendation.
Top-down motoring in the MX-5 is acceptable up to about 50 mph; the folding mesh wind blocker between the seats effectively cuts turbulence. If the ventilation system is set correctly, cruising with the top retracted in 50-60 deg. F temperatures is surprisingly enjoyable. When the weather becomes chilly, the manual convertible top can be erected and latched in less than 10 seconds while seated. At 70+ MPH, wind, tire and engine noise would cause fatigue on long trips, even with the top raised. As a long-distance cruiser, the cloth-top Miata is out of its element, but for road trip duty the Miata RF is the right choice.
Mazda has never wavered in its mission to continually improve its pure sports car. The Miata is unquestionably a niche 2-seater, likely to be a second or third vehicle in an owner's collection. Part of the MX-5's appeal is that there is no other sports car that matches is unique combination of affordability and driving enjoyment, and that's why the Miata has no competition.
