Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

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.

Mazda RX-7 could return in 2020

We like writing about the next Mazda RX-7 because it's like writing about the Chupacabra, Slenderman, or the Florida Skunkape, all of which are imaginary creatures seen by someone who knew someone who had an uncle whose dead great-grandfather's sister took a picture of it, invariably at night, while she was drunk, with her 1933 Kodak Brownie. Autocar is the latest with an RX-7 revival, saying it could come as soon as 2020 to celebrate Mazda's 100th anniversary. Before we get to that, let's take a brief look at RX-7 rumors. In 2009 there was speculation we'd get a concept RX-7 at the Tokyo Motor Show. That same year it was predicted the RX-8 would die to make room for a new RX-7 in 2012. In 2010 Mazda was developing a 300-horsepower rotary for the RX-7 that could run on gasoline or diesel and had better fuel economy and less oil consumption. Then Autocar said we could get the new RX-7 by 2013, a rumor that turned into a new RX-9 based on the Mazda MX-5 Miata platform. In 2012 the potential arrival date had become 2017. In 2013 the company CEO Masamichi Kogai said the equivalent of "Not gonna happen," and he said it again last year, just 90 days ago. It should be clear by now that this car is Mazda's version of the Lotus Esprit. Whew. Now that we're clear on all that, what does Autocar say? That a follow-up to the extinct RX-8 is coming that will sit on the new MX-5 Miata platform, and Mazda's vice president of European R&D said there are still 30 engineers working on rotary engines in partnership with universities. The successor will be front-engined and rear-wheel drive, have either two seats or 2+2 seating, and could be called RX-6, RX-7, or RX-9. That sounds like three distinct statements, only one of which is definitely true, that could possibly just maybe add up to a new RX-7, but could even more likely add up to a rotary-engined concept car that never sees production. We've only got five more years to wait, and since we've been begging at the RX-7 doors this long...
