Since its 1989 launch, the Mazda MX-5 Miata has become the most popular roadster/two-seat convertible sports car in the world, with more than a million vehicles sold. The fourth generation MX-5 was unveiled in 2014, and in late 2016, a new MX-5 RF (Retractable Fastback) model was added to the mix, featuring a rigid roof and buttresses that give the silhouette a more coupé-like appearance than the soft-top convertible.

In the sixth year of its current generation, MX-5 Miata gains a few small tweaks including adding as standard, Mazda's i-Activsense suite of driver-assistance features. The package includes forward-collision warning, automated emergency braking, blind-spot monitoring, and lane-departure warning. Also new for the 2020 sports roadster are a trendy new badging font, new keyfob, new exterior and interior color choices, and some top-trim add-ons. Apple CarPlay and Android Auto capability is now standard on Club and Grand Touring models, and the Grand Touring trim gets the sport suspension and limited-slip rear differential that also steadies the Club model.

The rest of the fun-driving sports car that added power and safety upgrades a year ago, remains intact.

I tested the RF (Retractable Fastback) convertible version that seems to be more than simply a convertible, and not quite a hardtop. The RF is more of a fastback that changes at your will, by slipping its retractable roof away in about 13 seconds while keeping its fastback profile. Then in another 13 seconds, the roof and true fastback can resume function. Upon opening, the roof section immediately overhead folds and stows below the buttresses, which lift temporarily out of the way. The glass rear window between the buttresses rolls down to give a more open-air feel and the entire power-folding roof mechanism occupies the same space as the standard manual-folding soft-top, so there’s no loss of trunk space.

The 2020 Mazda Miata MX-5 measures 154.1 inches long, 68.3 inches wide and 48.6 inches high (my RF trim was 49 inches high), on a 90.9-inch wheelbase. Light, at 2432 pounds curbweight for my test ride, and going as low 2338 pounds in some configurations, the MX-5 Miata performs in sports car fashion without sports car power. Minimum ground clearance for my RF trim was 5.32 inches – some trims are under 5 inches.

The interior fits like a cockpit, and seems to glove around the driver and passenger. Interior design and enhancements are upscale, cozy, intuitive and tech-filled. Visibility is excellent even with the top up, and while one would expect a noisy cabin from a roadster, engine and road noise and vibration permeate the environment even with the top in place. The infotainment screen is easy to read, and controls are easy to reach. Fun-driving is the two-seater’s mission, delivered in a tight space of 37.4 inches of headroom (36.8 for the RF), legroom of 43.1 inches and shoulder room of 52.2 inches.

MX-5 power numbers won’t knock your socks off, but they are fine for this light two-seater. MX-5 Miata uses a SKYACTIV 2.0.-liter DOHC 16-valve in-line 4 VVT multi-port electronic fuel injection engine, either manual or coupled to a 6-speed manual transmission. The system delivers 181 horsepower and 151 lb-ft of torque, easily accelerating the light roadster past traffic, up steep inclines, and excitingly along highway cruises, while finishing off a zero-to-60mph test track sprint in 5.7 seconds during a 14.4-second quarter-mile (hand-timed).

The system is EPA rated at 26mpg in city driving and 35mpg on the highway for the automatic and 34mpg for my manual shift. My mixed-use testing that was peppered with a lot of tire smoking and dragstrip acceleration showed an average of 29.9mpg.

A fun drive, the MX-5 was balanced on the road, though quick auto-cross turns exhibited some exciting-to-compensate-for body roll. The suspension allows you feel the road beneath you for full driver engagement.

The 2020 Mazda MX-5 is available in three trims – Sport, Club and Grand Touring -- and the RF is available in two trims – Club and Grand Touring. The MX-5 Sport bases at $26,580 with a manual transmission and 181-hp 2.0-liter engine, and $27,930 for a 6-speed automatic. The Club starts at $30,290 for the stick and $30,890 for the automatic, and adds a rear spoiler, cosmetics and tech; and the Grand Touring trim starts at $31,670 for the manual and $32,195 for an automatic trans, and adds dark finish wheels, rain-sensing windshield wipers, auto-dimming driver's side mirror, automatic climate control, leather-trimmed seats, Mazda Navigation System and more. My test roadster was the RF, starting with the Club in manual at $33,045 and Grand Touring at $34,425. For me, a roadster isn’t a roadster if it doesn’t have a stick, so I saved $325 by NOT getting an automatic on my Grand Touring trim.

The Eternal Blue exterior paint was at no extra charge, but I would have preferred Jet Black Mica (no charge) or Soul Red Crystal Metallic for $595. Already packed with standard items, no other cosmetic or weather packages were in my build. With a destination fee of $945, my test 2020 Mazda MX-5 Miata RF stickered at $35,370.
