The 2019 Mazda MX-5 Miata receives a newly refined powertrain, boasting 17 percent more power and greater fuel-efficiency
An available brown soft top complements MX-5’s KODO—Soul of Motion design
Numerous customer-driven improvements include a new rearview camera and more available i-ACTIVSENSE safety equipment

The Mazda MX-5 Miata has never been about power; it’s a car whose sole purpose is to help the driver and passenger fall in love with driving. But, a little extra power never hurts, which comes as one aspect of numerous updates for the 2019 model year.

Mazda’s engineers enriched MX-5’s SKYACTIV-G 2.0-liter engine with the goals of improved response, performance, feel and efficiency. The net results are 181 horsepower at 7,000 rpm—a 17-percent improvement—and 151 lb-ft of torque at 4,000 rpm, with a richer torque curve throughout MX-5’s entire rev range.

Speaking of rev range, redline has increased from 6,800 rpm to 7,500 rpm. Engineers were able to increase performance through several means, including:

Reducing internal mass and friction: Each piston has been reduced 27g in mass, thanks to a minimized skirt area. Connecting rods are 41g lighter than previous units.
Reducing exhaust loss: The upgraded engine carries an increased valve opening angle and valve lift height. The inner diameter of the exhaust manifold has also been increased. The net results are a 30-percent reduction in pumping losses.
Improved combustion: Reconfigured intake ports and new high-diffusion, higher-pressure fuel injectors improve the tumble and swirl of fuel in the cylinder and better-atomize fuel. The benefit is improved efficiency and torque at all rpm.
Dual-mass flywheel: Replacing the single-mass flywheel with a low-inertia, dual-mass flywheel improves smoothness and responsiveness.
A new exhaust system with richer sound quality.
New final drive ratio: The transmission’s final drive ratio has been increased from 3.454 to 3.583 in models equipped with an automatic transmission in order to improve linear response to match the driver’s intentions. Gear ratios are otherwise unchanged from previous models.

Beyond engine improvements, the 2019 MX-5 introduces an available brown canvas soft top, new black metallic 17-inch wheels, a newly telescoping steering wheel (30mm of travel), easier-to-open doors and revised door stops and revised cupholders and seat levers.

On the safety front, the new MX-5 will be sold with a new, standard rearview camera and newly available features such as Traffic Sign Recognition and Smart City Brake Support in addition to other i-ACTIVSENSE safety technologies found throughout various trim levels. In the process of gaining many new features, the 2019 MX-5 gains just 7 lbs. from previous models, owing to a strict adherence to Mazda’s “Gram Strategy” and ingenious solutions like adopting an aluminum steering shaft in place of the previous steel unit.

When the fourth-generation MX-5 launched, its development team rallied around the idea of innovating in order to preserve. The latest round of innovations aim to continue that mission.

The 2019 Mazda MX-5 will be available in the U.S. this fall, with pricing, packaging and full specifications to be announced closer to on-sale timing. Details concerning the 2019-spec Global MX-5 Cup racecar will also be announced at a later date.
