Mazda halts Mazda3 sales for fuel tank problem

Mazda is issuing a stop sale and recall on 14,406 examples of the 2015-2016 Mazda3 in the US with build dates between May 21, 2015, and August 24, 2015, due to a possible fuel leak. There are no reports or accidents or injuries from this problem. According to the company, a defective fuel shut-off valve can allow gasoline to move from the tank and fill the charcoal emissions canister. If it gets too full, there can be a leak, which obviously carries the risk of a possible fire. The engine might stall, as well. Affected owners will be notified to bring their Mazda3 in "as soon as possible." Dealers will inspect the vehicles, and if a problem is found, the fuel tank and charcoal emissions canister will be replaced. During the downtime, customers will get a free rental or loaner car, as well. Those who are particularly concerned can also call Mazda roadside assistance to have their vehicle delivered for the check and possible repair.

A defect in the fuel shut-off valve may allow fuel to flow from the fuel tank into the charcoal emissions canister. With this condition, the check engine light may illuminate, and if the fuel exceeds the canister capacity, fuel leakage could occur, increasing the risk of a fire and/or engine stalling. Approximately 14,270 vehicles in the U.S. and 136 vehicles in Puerto Rico are affected. Owners of subject vehicles will be notified by mail in early October. They will be informed to bring their vehicle to the nearest Mazda dealer as soon as possible. Dealers will inspect the fuel tank to determine if the defect exists on the vehicle. If the defect exists, the dealer will replace the fuel tank and charcoal canister at no cost to the customer. A rental or loaner vehicle will be provided at no cost to the owner, until the vehicle is repaired for this concern. If there are no concerns, the vehicle will be returned to the customer. Should a customer not want to drive the vehicle to the dealership, they may contact Mazda's 24-hour Roadside Assistance service at 800-866-1998 and have the vehicle picked up and delivered to the dealership. There have been no reports of accidents or injury related to this issue.

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.

2015 Mazda3 finally pairs 6-speed manual with larger engine

With all of the hype and anticipation surrounding the 2016 Mazda MX-5 Miata, the Japanese brand was able to sneak another driver-oriented model into its lineup. The company's spec page for the 2015 Mazda3 hatchback and sedan have been updated to list the Skyactiv-G 2.5-liter four-cylinder as finally being available with a six-speed manual transmission, in addition to the previous six-speed automatic. The automaker had promised the row-your-own gearbox with the bigger engine back when it first announced the new Mazda3, but it waited a model year to actually put the combo on sale.
According to Mazda's specs, the manual gearbox trims 40 pounds off of a hatchback or 54 pounds off of a sedan in s Touring and s Grand Touring trims. However, shedding that weight doesn't necessarily boost fuel economy. The six-speed hatch is rated at 26 miles per gallon city and 35 mpg highway, compared to 27/37 for the automatic. The manual sedan is rated at 25/37 city/highway mpg, versus 28/39 with the auto. Buyers can save a little money by opting for the manual, though. Regardless of body style, it's about $1,050 cheaper than the automatic.
Autoblog reached out to Mazda and learned that the 2.5L 6MT models started hitting dealers in August. The 2.5 wasn't initially available with the stick because, "We had to prioritize engineering resources and the 2.5L 6MT was not a high priority combination. Globally, smaller engines are preferred in terms of sales," a Mazda spokesperson explained via email. The automaker also notes that Austrailia will probably be the only other market outside of North America to get the six-speed gearbox with the larger engine.
