Mazda3, CX-5 earn IIHS Top Safety Picks

Mazda technologies like SkyActiv-Body and SkyActiv-Chassis, plus ultra-high-tensile steel, six airbags, "crusable" brake and accelerator pedal assembly and collapsible steering column have helped the 2013 Mazda3 and 2014 Mazda CX-5 win Top Safety Pick laurels from the Insurance Institute for Highway Safety (IIHS). It's the second year in a row for the Mazda3.
The accolade is earned by receiving "Good" marks for frontal moderate overlap crashes, side and rear impact crashes, and tests of roof strength. Remember, the small overlap test that the IIHS commenced in August 2012 has lately tripped up some makers who have excellent safety reputations.
The Mazda3 and CX-5 join offerings like the Dodge Dart, Hyundai Elantra, Mitsubishi Outlander Sport and Subaru Forester among the 117 vehicles so far declared Top Safety Picks - which is different than the 13 named Top Safety Picks+, mind you - for this year.

Jay Leno celebrates Mazda Miata's 25th birthday

Ask a car enthusiast what the best driver's car on the road is, and the Mazda MX-5 Miata is very likely to come up rather quickly. Unjustly saddled with a reputation as a "chick's car," the Miata has been, over its three generations, one of the finest driving instruments ever built - it's light, agile and rear-wheel drive with direct, snappy steering, an engine that revels in being revved and a precise, smooth-shifting transmission. The fact that it's ridiculously affordable and reliable is simply a bonus.
It should come as no surprise then, that a car with these traits has endured for 25 years, a milestone reached only by some of the most famous nameplates in the auto industry - Corvette, Mustang, F-150, SL, M3 and so on. To celebrate its 25th anniversary, Jay Leno spent some time with the little roadster that could, while also chatting with two of the Mazda employees that were central to the MX-5's arrival on the world's automotive scene, Bob Hall and Tom Matano.
Take a look below for the latest video from Jay Leno's Garage on the excellent Mazda MX-5 Miata.

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.
