Mazda seemingly confirms turbo Mazda3, plus reveal date

Yes, you read that right, Mazda seems to have confirmed that a 2021 Mazda3 turbo is on the way. The company replied to multiple tweets asking about such a car, including one from yours truly, with a teaser video and the phrase "Power comes to those who wait."

It does have a soundtrack of a mean sounding four-cylinder. It also has a date: July 8, 2020. So we should see the car in just a couple of weeks. Many reports have circulated about the turbo Mazda3. The most recent asserts that it will be available in both sedan and hatchback variants, but that it may only come with an automatic transmission. The engine will probably be the same turbocharged 2.5-liter unit from the Mazda6, CX-5 and CX-9, which makes 250 horsepower and 310 pound-feet of torque. That would put it in close proximity to the VW GTI and Subaru WRX. We'll be curious if Mazda also offers all-wheel drive, since it's available with the turbo engine in the CX-5 and CX-9. Odds are the car will also be tuned and marketed as a more mature vehicle than other hot hatches or the old Mazdaspeed3. Related Video: This content is hosted by a third party.

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.
