Honda, Nissan and Mazda recalling 3 million vehicles for airbag inflators

Three million more vehicles can be added to the worldwide tally to be repaired for the faulty airbag inflators supplied by Takata. Honda, Nissan, and Mazda have all issued recalls to replace the bad part, including about 1.2 million of them in North America. NHTSA has been investigating all three companies, plus Chrysler and Toyota, for potentially affected vehicles.
Honda is recalling roughly 1.02 million Civic, CR-V, Odyssey and Element models In North America, built between April 2000 and October 2002. Mazda needs to repair 14,794 units of the RX-8 and Mazda6, and Nissan has 228,000 vehicles in North America to be fixed.
Chrysler is also starting what it calls a "regional field action" to replace the inflators in the 2006 Dodge Charger, according to a company spokesperson. The company says that it has not yet found the problem in any of its vehicles, but it's being done "out of an abundance of caution." The final number of Chargers affected will be announced later this week.

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

2016 Mazda CX-3 scores 29/35 mpg EPA ratings

Looking for a subcompact crossover that won't cost you too much at the pumps? Your best bet is now the new Mazda CX-3, according to fuel economy figures released by the EPA. Mazda's new baby crossover has been rated by the US government agency at 29 miles per gallon in the city, 35 on the highway, and 31 on the combined cycle. That's in front-drive spec, giving the CX-3 better fuel economy than anything else in its class (at least, that is, with an automatic transmission.) Option it with all-wheel drive and you'll take a slight penalty at 27 mpg in the city, 32 on the highway, and 29 combined. According to Mazda that still "makes it among the most fuel-efficient all-wheel-drive vehicles available in the US." Whichever drivetrain option you go for, the CX-3 packs a 2.0-liter inline-four with direct injection (Skyactiv-G in Mazda-speak) good for 146 horsepower and just as much torque, mated to a six-speed automatic transmission. The first examples will begin reaching American showrooms later this summer.

As Mazda's first foray into the quickly burgeoning subcompact crossover class of vehicles, CX-3 provides those seeking a purposeful, stylish and sporty vehicle option that bucks convention. CX-3 offers standard keyless ignition and backup camera, and is available with features that are unrivalled in its class like Mazda Radar Cruise Control, adaptive LED headlights and Mazda's signature driving experience. Front-wheel-drive models have EPA-estimated fuel economy of 29 mpg city/35 mpg highway/31 mpg combined, while models equipped with Mazda's predictive i-ACTIV AWD have EPA-estimated fuel economy of 27 mpg city/32 mpg highway/29 mpg combined. That makes it among the most-efficient all-wheel-drive vehicles available in the U.S. "SKYACTIV Technology means we don't have to compromise when it comes to performance, efficiency and fun-to-drive dynamics," said Jim O'Sullivan, president and CEO, Mazda North American Operations.
