The 2021 Miata RF is powered by a 2.0-liter four-cylinder engine. It produces 181 horsepower and 151 lb-ft of torque. There are two different transmissions: the standard six-speed manual or an available six-speed automatic. Manual transmission 2021 Miata RF models get 26-city/34-highway mpg. Automatic transmission models squeak out a bit more fuel economy, getting 26-city/35-highway mpg. As with every other Miata, RWD is standard for the 2021 Miata RF.
Both the 2021 Miata RF Club 6MT and the Grand Touring 6MT trims have standalone tunnel under bars, a front tower brace, and lower arm bar options. Those same trims have access to the Brembo/BBS Recaro package, which adds Brembo performance front brakes, 17-inch BBS alloy wheels, side sill extensions, a rear bumper kit, and Recaro heated seats.
Since the 2021 Miata RF starts at the Club trim instead of the Sport trim, it comes with more standard features than a regular Miata. Standard tech includes Apple CarPlay, Android Auto, Bluetooth, two USB ports, SiriusXM satellite radio, HD Radio, a 7-inch touchscreen, a nine-speaker Bose stereo system, low-speed forward collision warning, automatic emergency braking, blind spot monitoring, rear cross-traffic alert, lane departure warning, and a rearview camera. Other features are available on the Grand Touring trim, such as a GPS navigation system, traffic sign recognition, adaptive headlights, automatic high-beam headlights, and rain-sensing windshield wipers.
