2016 Mazda MX-5 Miata 2.0L First Drive [w/video]

The 2016 Mazda MX-5 Miata is easy to comprehend. It is an enthusiast roadster in its purest form. There's no need for any sort of sales pitch. You don't have to ramp up in order to get people excited about it. Say the words "new Miata" to anyone who cares about cars, and you've immediately got their attention. And now that I have yours, I'll to cut right to the chase. It's brilliant. That's a fact I've known for a while. I drove the Japanese-spec ND Miata in Spain earlier this year, with the 130-horsepower, 1.5-liter engine that we aren't getting in the United States. The new Miata is a modern day reincarnation of the original NA that stole our hearts in 1989. It's smaller and lighter than the outgoing NC, yet boasts more interior room. It's comfortable. It looks great. And it drives like a Miata should. In other words, it's perfect. So what about this US-spec car, then? It's got more power – 155 horsepower and 148 pound-feet of torque from Mazda's 2.0-liter Skyactiv four-cylinder engine. But it's also heavier. Our car weighs 2,332 pounds, compared to the roughly 2,200 pounds of the 1.5-liter car. Yes, the ND Miata loses 12 hp compared to the outgoing NC, but it's up 8 lb-ft of torque. Plus, according to Mazda, because of the improved powerband, anytime you're under 5,700 rpm the new Skyactiv engine is stronger than the old MZR mill. It's more efficient, too. With the manual transmission, the Miata is estimated to achieve 27 miles per gallon in the city and 34 mpg highway. That a jump of six mpg in both categories compared to the old six-speed. Consider this: The Japanese-spec car uses a 130-hp engine, which I found to be perfectly adequate. The increase in power for the US-spec car mostly just balances out the extra weight, but it also improves performance on the highway. Hit the throttle in sixth gear with the 1.5 and nothing happens. Do the same with the 2.0, and there's movement. Low-end power is far more important in the US than it is in other markets, and that's why our car has the larger engine. "North America is why the two-liter car exists," engineer Dave Coleman told me. Plus, 155 hp power means you eke out the Miata's dynamics at legal speeds. 45 miles per hour in an MX-5 is a far more exhilarating experience than that same speed in any supercar. So yeah, it's not powerful. But to paraphrase Jay-Z, the MX-5 is a super car, not a supercar.

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.

Mazda's EV resistance may mean CAFE trouble ahead

Is Skyactiv the limit for Mazda? The Japanese automaker has ridden its gas-powered engine technology platform to the upper end of fleetwide fuel economy among automakers in the US. But the company's lack of electrification, either hybrids of plug-in vehicles, combined with increasing sales of crossovers, may limit future fuel-efficiency gains, Automotive News reports. Mazda has no plans to add battery-electric variants across its product line, the publication says, citing comments from Mazda North America CEO Masahiro Moro. So far, the dependence on Skyactiv has worked well, as Mazda was the second automaker - after electric-vehicle maker Tesla Motors – to meet the US fuel-economy mandate of 34.1 miles per gallon for 2016. Additionally, Mazda plans to unveil the second-generation version of Skyactiv next year. Using a technology called "homogenous-charge compression ignition" (HCCI), Mazda's gas-powered engines will approximate the compression in diesel engines, boosting fuel economy accordingly. Because of that development, Mazda's Moro is "very confident" that the company will meet the US Corporate Average Fuel Economy (CAFE) mandate for 2021. With no plans for US plug-ins or hybrids (Mazda's only hybrid, a variant of the Mazda3, is sold in Japan), Moro is not so sure about meeting the 2025 CAFE mandate of 54.5 mpg (which equates to a "real world" fuel economy of about 40 mpg). Additionally, Mazda's "biggest regulatory headache" will be meeting California's mandate that 15 percent of the state's new-vehicle sales be zero-emissions within the next decade. In 2011, Mazda laid out its strategy of leaning on its Skyactiv technology instead of moving to drivetrain electrification as a way to boost fleetwide fuel economy, saying at the time that "you can't out-Toyota Toyota and you can't out-Honda Honda." The company also took a strong stance against even the idea of electrification in vehicles. According to the US Environmental Protection Agency (EPA), Mazda's model-year 2015 vehicles averaged 30.1 mpg, beating out Honda's 28.9 mpg, Subaru's 28.7 mpg, and Nissan's 28.3 mpg. Mazda's fleetwide fuel efficiency increased from 29.4 mpg for the 2014 model year, and from 28.1 for the 2013 model year, according to the EPA.
