2014 Mazda3

The Cure For The Common Corolla
I hate the Toyota Corolla. I'm not talking about the new 2014 model; I can't yet judge a car I haven't driven. I'm referring to the current, old-as-dirt sedan. As an appliance, I get why people buy it, but it represents everything that I, as a car enthusiast, dislike. I don't like looking at it, I don't like sitting in it, and I really don't like driving it. There is absolutely no amount of emotion dialed into any part of the Corolla experience and every other vehicle in the segment is a far better choice. But still, somehow, Toyota sells 'em like hotcakes.
Thankfully, there are a lot of people who agree with me. And for folks like us, companies like Mazda exist. This small Japanese automaker places emotion and driver involvement as its top priorities when creating new products, and mostly - especially in recent years - the end results have been great. The new CX-5 crossover is a doll, to say nothing of the rakish and lovely new Mazda6 that launched earlier this year. And let's not forget the Miata...

2019 Mazda3 fuel economy announced for AWD, hatchback models

Although Mazda engineers gave us fuel economy numbers for one configuration of 2019 Mazda3 at the car's Los Angeles debut, there were still a few versions left out. Now Mazda has released the data for every body style, drivetrain and transmission configuration. That includes the all-new all-wheel-drive iteration, which we will have a full review of this week. Discerning these numbers is a tad tricky since there are three powertrain combinations for each 2019 Mazda3 bodystyle, and they all get slightly different fuel economy. We've listed the different combinations in a chart below: There are a few key takeaways, the first being that the sedan is always the most efficient version of the Mazda3, likely because of better aerodynamics compared to the hatchback. Second, all-wheel drive will cost you fuel economy due to the extra weight of the axles and differential, and the added drag on the engine. Third, the most efficient versions of each body have the same fuel economy numbers as the outgoing Mazda3. The manual transmission-equipped Mazda3 has actually improved fuel economy over the old version by 2 mpg on the highway, and 1 in combined driving. Also worth noting is that only one trim level of the sedan is available with cylinder deactivation and front-wheel drive, and that's the top-level Premium trim. Opting for all-wheel drive on any trim or body style will come with an engine with cylinder deactivation. The hatchback is also the only Mazda3 available with a manual transmission, and it's only offered on the front-drive version.

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.
