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.

2019 Mazda MX-5 Miata 30th Anniversary Edition goes bold

For a car with a mischievous grin and penchant for fun, the MX-5 Miata's color palette is on the drab side, but thankfully the 30th Anniversary Edition gets a vivid hue called Racing Orange. Mazda says it "evokes the breaking dawn of an exciting new day," and that it's partly inspired by the bright yellow of the Miata Club Racer concept from 1989. That's all well and good, but it looks to us more like the orange from the 1991 Le Mans-winning Mazda 787B race car. Whatever the reason, we dig the color. It will be important that the new owners like it, too, because the color is everywhere. It's on the brake calipers, door sills, air vents, stitching and piping. Everything else is a black or charcoal color, including the gorgeous Rays forged aluminum wheels, exclusive to this model, and the Alcantara trim on the dash, doors and seats. All versions of the special Miata come with Recaro seats, Brembo brakes, Bose sound system and Apple CarPlay and Android Auto. The manual models add a limited-slip differential, Bilstein shocks and a front shock tower brace. Mazda isn't making many of these special Miatas, with just 3,000 of the soft top and RF combined for the world. The U.S. will get only 500. Customers can order one now at a special configuration website, and they had better bring plenty of cash. The manual soft top starts at $35,915, and the manual RF starts at $38,515. Adding an automatic ups the price by $499 on the soft top and $400 on the RF. Related Video:

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.
