Evo pits Toyota GT86 vs. Mazda MX-5 Miata

The latest Deadly Rivals episode from Evo gets the Mazda MX-5 Miata and Toyota GT86 (our Scion FR-S) on track for a shakedown and a whole lot of drifting with Dan Prosser behind the wheel. The UK-spec coupes have slightly different power ratings than ours, but it's all close enough to be comparable. Their Miata has 158 horsepower (ours has 155), 148 pound-feet of torque, takes 7.3 seconds to run from naught to 60 62, and costs 22,695 pounds. The GT86, on the other hand, lists a 7.6-second dash to 60 62, and a base price of 25,000 pounds. The GT86 also weighs 400 pounds more than the Mazda. That's true in the States, too – curb weight for our MX-5 is 2,332 pounds, whereas the Scion FR-S comes in at 2,758 pounds. Both cars lauded for excellent shifting, but one of them has a better front end, a sweeter engine note, more controllable cornering behavior, and is faster by a tenth of a second around the test track. And Prosser doesn't mention it, but one has a lot more body roll. But it takes more than all that to make a winner, so check out the video above to see which is which.

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 Mexico debuts Mazda3 Turbo before official U.S. reveal

We should have been keeping an eye on our neighbors to the south, who did us the favor of showing off the turbocharged 2021 Mazda3 last week. The automaker teased the reveal for the U.S. market to happen on July 8. It's reasonable to expect slight changes between our two countries, but the Mexico introduction makes a good base to know what we're getting. The prime specs: 2.5-liter Skyactiv-G turbocharged four-cylinder with 227 horsepower and 310 pound-feet of torque. As suspected, this is the same engine found in the Mazda6, CX-5, and CX-9. As such, we expect those output figures are based on using 87 octane gasoline; in the other three Mazda offerings, 93 octane gas unlocks 250 hp and 320 lb-ft. So at worst, the Mazda3 turbo makes 41 hp and 124 lb-ft more than the naturally-aspirated engine in the current hatch and sedan. At best, the improvement runs to 64 hp and 124 lb-ft. Comparing the turbo Mazda3 to the segment-standard Volkswagen Golf GTI, the incoming 2021 German will make 241 hp and 273 lb-ft. Only a test drive will reveal how the battle of sportiness vs luxury turns out for the Mazda. The numbers make a case for the former, but there's enough of the latter to sway us into believing this will primarily be a quicker Mazda3, with nary a hardcore edge. The only transmission mentioned is a six-speed automatic with paddle shifters that sends power to both axles via mandatory all-wheel drive. In Mexico there are only two Mazda3 trims, which start at 329,990 pesos ($17,050 U.S.) and 429,900 pesos ($19,294 U.S.). The turbo will introduce two new trims there that start at 489,900 pesos ($21,987 U.S.) and 529,900 pesos ($23,782 U.S.), MSRP increases of about 29%. For the supplemental dosh, the Mazda3 turbo in Mexico comes with a leather interior, sunroof, 12-speaker Bose audio, Android Auto and Apple CarPlay, LED headlights, blind-spot monitoring and auto-tint side mirrors, reversing sensors, and black 18-inch aluminum wheels.  Other than those black wheels and some badging, though, there's nothing to differentiate the forced-induction model from the naturally aspirated one. When a Jalopnik source tipped that site to some 2021MY Mazdas based on dealer codes, there was a "MAZDA3 HB PP TURBO." That "PP" likely stands for Premium Package, which is the highest trim offered on our Mazda3 right now, already comes with 18-inch black wheels, and starts at $28,445 after destination.
