Five automakers now being investigated by NHTSA for airbag woes

It appears that Toyota's renotification to owners of recalled vehicles from last year is just the tip of the iceberg for what could potentially be a much larger industry-wide recall. The National Highway Traffic Safety Administration is opening a preliminary evaluation investigation into roughly 1.1 million vehicles from Chrysler, Honda, Mazda, Nissan, Toyota and parts supplier Takata regarding faulty airbag inflators in several models.
NHTSA has received six reports - three directly, two from Takata and one from Toyota - of vehicles with ruptured airbag inflators from 2002-2006, which resulted in three injuries. So far, all six incidents have occurred in high humidity areas like Florida and Puerto Rico. According to Toyota's latest recall announcement, the inflators may have an improper propellant that could cause it to rupture in a crash and the bag to deploy abnormally.
This new investigation follows a previous recall from April 2013 of about 3.4 million vehicles worldwide for the airbag inflators from Takata. As Autoblog reported, Toyota jumpstarted the new situation when it found that the original list of serial numbers for the faulty part was incomplete and discovered more cars in need of replacement. Honda and Nissan told us that they were investigating whether further models would need called in again as well. Mazda told Autoblog: "Regarding the current Takata situation, we're working closely with NHTSA and investigating the situation, but nothing else to report at this time." Chrysler Group responded to us with the statement: "Chrysler Group engineers are conducting the appropriate analysis. The Company will cooperate fully with the National Highway Traffic Administration."

Mazda Miata livery design contest in Forza Horizon 2

If you're into video games, creativity, the Mazda MX-5 Miata and South by Southwest, then there's a contest in Forza Horizon 2 you'll want to know about. Called the Livery Design Contest, your job is to head to Xbox Live sometime before midnight on January 4, 2015 and design a paint job for the 1994 Miata in the game. A panel of judges will evaluate designs for originality, aesthetic design and technical proficiency, and settle on up to five semifinalists who will regroup in the next round, which is public voting. Come January 26, the public can begin voting on its favorite design until February 12, to narrow the semifinal pool down to two. Those two will be flown to South by Southwest in Austin, TX – which happens from March 13-22 – and one of them will be crowned the winner. Said winner will lumber away from the event with $3,500 worth of prizes, including a 55-inch curved-screen television, and their livery will be free to all of the minions playing Forza Horizon 2. There's also a Mazda hub on Xbox Live for everyone to take an in-depth look at the 2016 Miata, if you just like to watch, in which case you may also want to see the related videos joining the press release below. MAZDA TEAMS UP WITH XBOX TO LAUNCH 2016 MX-5 - Mazda MX-5 Livery Design Contest Now Live in Forza Horizon 2 - - Branded hub allows Xbox users to virtually tour 2016 MX-5 and enter MX-5 design contest - Winning design to be featured in Forza Horizon 2 and gifted to all players IRVINE, Calif. (December 4, 2014) – For the second consecutive year, Mazda North American Operations (MNAO) is teaming up with Xbox, this time to promote the launch of the 2016 Mazda MX-5 and give Forza Horizon 2 players the chance to enter the Mazda MX-5 Livery Design Contest. An interactive experience with the 2016 Mazda MX-5 and information on the design contest will be available through the Mazda branded hub on Xbox 360 and Xbox One. The Mazda MX-5 Livery Design Contest, which is now live through January 4, 2015, will give Forza Horizon 2 players the opportunity to design the livery for the 1994 Mazda MX-5 currently available in-game. Two finalists will be awarded a trip in March to South by Southwest 2015 for the final design showdown. The winner will walk away with a new 55-inch curved TV, audio music system, Xbox One Kinect console and one MadCatz Racing Wheel estimated at $3,499.95.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.
