2017 Mazda MX-5 Miata RF Quick Spin | Elevate yourself

It's unusually hot in Western Washington; the early August sun beams through skies rendered hazy by fires a few hundred miles to the north. If you're not moving, it gets a bit oppressive, since there's just enough humidity to feel it and not enough wind to relieve it. Instead of huddling inside, window shades drawn, fan blowing hot air around impotently – this is how most Washingtonians, 75 percent of whom don't have A/C, handle the heat – we're taking our fan on the road. The best way to beat the heat, it turns out, is to climb into the forests. For this adventure in body temperature regulation, we've got a Mazda MX-5 RF, the Miata's semi-targa-topped variant, and a few hours of time. And the Cascade Mountain's foothills, thickly coated with Douglas firs and, higher up, subalpine firs soaking up as much sun as they can in the short growing season. I've lived near the foothills nearly all my life, but there's a lot of the Cascades I haven't explored. One area is Chinook Pass, a mountain road that crests at 5,430 feet. Looming almost 9,000 feet above it is Mount Rainier, so close you can almost touch it. Just about 100 feet below the summit is Tipsoo Lake, startlingly clear and sporting enough wildflowers to make The Sound of Music look like a movie about Rommel's North Africa campaign. But that's jumping ahead a bit. Between me and the summit is about 90 minutes of driving, through the suburbs and into the Enumclaw Plateau, and then along the chalky White River and up into the mountains. Plenty of time to focus on nothing but the surroundings, and the quality of the cooling action provided by the little Mazda. A quick word about the car, and my own biases – I love Miatas, but I have a complicated relationship with the latest MX-5, having owned a much more visceral (and much slower) first-gen car for about six years. On paper, it's this perfect modern interpretation of the original. It's light, it's a momentum machine, the steering's just a tad overboosted, and it has a playful amount of body roll while maintaining a healthy amount of mechanical grip. It looks aggressive enough, too, a major complaint of many folks about the last-gen car's Joker smile. The interior is largely brilliant, amazingly simple and interesting for such a lithe car. And yet, I have never found the new car to be as charismatic as my old Miata, with all its flaws. This puts me in the minority; most MX-5 fanatics find the ND to be a great compromise.

2014 North American Car and Truck/Utility of the Year finalists announced [w/poll]

The 2014 North American International Auto Show is right around the corner, which means it's high time we found out which cars and trucks would be finalists for the prestigious North American Car and Truck/Utility of the Year awards.
The finalists - three in cars and three in three trucks/utilities - are dominated by American brands, with two-thirds of the finalists hailing from either General Motors or Chrysler (don't worry Ford, there's always next year), while outliers from Mazda and Acura can be found in each contest. Here now is the list of finalists for the big prizes:
2014 North American Car of the Year:

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.
