2019 Mazda MX-5 Miata First Drive Review | More power is the icing on top

SAN DIEGO — When Mazda announced that the 2019 Mazda MX-5 Miata was getting a serious increase in power, I was both excited and nervous. I was excited because more power is always exciting, and it was no insubstantial increase. At 181 horsepower, it's the most powerful production Miata ever offered, beating out turbocharged Mazdaspeed Miata's 178 horsepower. Plus it has more revs to play with. But what had me worried was whether this power would mess up the friendly, playful character of the Miata. The 155-horsepower 2.0-liter engine is just about perfect, almost universally loved by the Autoblog staff and other reviewers, with good midrange torque and short gearing that always made it feel quick in nearly every rev range. It felt like the right amount of power for the chassis, too. There was just enough to get it loose without working too hard, but it wouldn't spin you around unexpectedly. I could imagine a couple of ways the new engine could affect that sweet balance, too. A bit too much power could risk some of the Miata's accessibility and predictability. It might become more serious and less fun-loving. I also feared that in pursuit of a higher redline and more horsepower, the low-end of the rev range might become painfully slow. Honda owners know this feeling whenever their VTEC-equipped screamers drop out of the aggressive cam profile, and the Toyota 86 and BRZ suffer from an awful lack of torque right in the mid-range that doesn't recover until nearly redline. All of this was on my mind when the assembled reviewers were briefed by Mazda engineers about the car. It started out like most presentations, with a brief rundown of the goals of the car and what Mazda has done with the model so far. Then came a chart showing the power curves of the NC, current ND, and the 2019 model, and my fear of a loss of low-end grunt dissipated. The amount of power and torque over engine speed is nearly identical between the old and new ND Miatas right up to around 4,500 rpm. And then from there, the 2019 continues making more power all the way to its 181-horse peak at 7,000 rpm, 500 rpm higher than the previous model's redline. This was a good sign. Mazda managed to get these gains with no sacrifices through many small upgrades. The throttle body is wider with a slimmer throttle plate, the intake manifold has longer runners and dual paths, and the intake ports are larger.

Mazda's Tokyo concepts have us wishing for more Mazdaspeed

It's been a while since we've seen any new Mazdaspeed machinery, and we're sorry to report that today isn't the day the wait ends. But if you want to see what they might look like based on Mazda's latest models, the Tokyo Auto Salon will be the place to be in a couple of weeks. Turns out the Zoom-Zoom brand has a whole raft of performance models in store for the aftermarket expo. Most intriguing to our eyes is the trio of Racing concepts – one based on the MX-5 Miata roadster, one on the CX-3 crossover, and one on the Mazda6 sedan. Each is done up in black with full aero kit, new rolling stock, and Alcantara interior. An adjustable suspension is the big change to the MX-5 – known simply as the Mazda Roadster in Japan – which also features red trim. As does the CX-3, while the Atenza (which we know as the Mazda6) goes for a more monochromatic, murdered-out appearance. The rally-prepped Mazda2 (known domestically as the Demio) focuses on a stripped-out interior with bucket seats, racing harnesses and a roll cage. There's a spec racing MX-5 in white livery with roll cage and tow hooks as well to join the Global Cup roadster we've already seen. That also goes for the RX-Vision and LM55 Vision Grand Turismo concepts which have already made the rounds but will be on display at the Tokyo salon as well. But it's those three Racing concepts that leave us salivating for production performance models to come – and hopefully come to North America in the process. Related Video:

Mazda previews 2016 Miata Global MX-5 Cup racer

At this point, we all know that the Mazda MX-5 Miata is a highly capable racing platform. Mazda even claims that the car is the most road-raced model in the world. Fittingly, then, the Japanese brand is making a huge announcement about the future of motorsport for its next-generation convertible. The MX-5 Cup is going worldwide in 2016 as the MX-5 Global Cup, and all of the racers are getting behind the wheel of the upcoming fourth-gen Miata, similar to the gorgeous redhead pictured above.
"It has long been our goal to see Mazda fans around the world competing in identical MX-5s, and the launch of the 2016 MX-5 Miata is the perfect time to make this goal a reality," said Masahiro Moro, Managing Executive Officer in charge of Global Sales, Marketing and Customer Service for Mazda in the company's announcement.
The racing version makes its grand debut at this year's SEMA show, although at the moment it's really more of a concept. Mazda confirms that the racer uses the 2.0-liter SkyActiv four-cylinder, but the other important parts like tires, suspension and safety equipment are not yet determined. The cars "will be sold ready to race from a single supplier," according to automaker's announcement for the series.
