Miata is always the answer, but not always the best one

The Mazda MX-5 Miata is a surprisingly versatile car. Not only is it hilariously fun on back roads and closed courses, it can also be a decent daily driver thanks to its solid gas mileage and usable trunk. But, it doesn't excel in every driving situation. Specifically long trips at high speeds, and those involving canine companions. This weekend, I did a roughly 500-mile round trip to my parents' home in Indiana to pick up my recently adopted dog. The trip was 90-percent highways, and I heard every single mile. Our MX-5 Miata Club has the minimally insulated top also found on the base level trim, and at highway speeds the wind and road noise fills the cabin with a loud, steady roar. This likely won't be a problem for fans of white noise, and it can be overcome by the stereo. However, over a few hundred miles, it starts to get old. The suspension, while superb for carving corners, also gets tiresome. On rough Rust Belt highways, it would become a bit overwhelmed, and the whole car would shiver and shake. On the plus side, nothing squeaked, rattled, or fell off in these instances. There are a few other quirks that show up on long trips. The small pedal box and floor-mounted throttle means that there isn't a particularly comfortable place to rest your right foot when the cruise control is set. Neither the door nor the center console have much padding either, so leaning your knees against them for long periods of time isn't advisable. The good news is that the seat itself was surprisingly comfortable, and never once was I feeling any back pain. Plus, when not using the cruise control, the seating position is great, allowing me to stretch out and relax. When I picked up my four-legged compatriot (a 7-year-old mix of unknown breeds named Ruby, pictured above), things became a tad tight. Standing up, she thoroughly filled the passenger compartment. For reference, she's a little over 50 pounds and stands a little more than 2 feet tall. Much bigger dogs, like my family's coonhound and German shepherd mix, won't really fit. This also made her prone to nearly face-planting on the dashboard anytime the car slowed down. She eventually figured out that simply curling up on the seat bottom was the best choice, and then slept for most of the trip. So it worked out, but I think I may have found the limit of a Miata's dog capacity. Would any of this make me want a Miata less? Certainly not. That is if I had a second car.

Honda sees sales up but profit sliding 16 percent in 2017-18

TOKYO - Honda forecasts a 16 percent fall in operating profit for the current financial year as the Japanese automaker sees higher auto sales being offset by a stronger yen and research-and-development costs. Japan's No. 3 automaker said it expects an operating profit of 705 billion yen ($6.34 billion) in the current FY2018, down from 840.7 billion yen posted in the fiscal year just ended, and lower than an average estimate of 850.8 billion yen from 23 analysts polled by Thomson Reuters I/B/E/S. It sees a 14 percent slide in net profit to 530.0 billion yen this year, down from 616.5. Honda's projections are based on a forecast that the yen will average 105 yen to the U.S. dollar through next March, stronger than the 108 yen rate in the year just ended.BUT CAR SALES ARE UP At the same time, there's good news as Honda expects its global vehicle sales to edge up 1 percent to 5.08 million this year, bolstered by growth in Asian sales to 2.06 million units, beating out North America to become Honda's top market as more Chinese drivers flock to its cars. The company expects to sell 1.92 million vehicles in North America, 2.5 percent less than the year just ended as it struggles to sell sedans including the Accord, which have fallen out of fashion in the past few years. Honda has been ramping up production of SUVs to keep up with strong demand for larger models in the United States, although overall vehicle sales show signs of slowing following a boom cycle after the global financial crisis. Mazda is taking a similar strategy, announcing on Friday it would expand production of SUV crossover models at home, while equipping overseas plants to enable more flexible production of models according to market needs. Japan's No. 5 automaker forecast a 19 percent jump in operating profit for the current financial year as it expects higher sales volumes, particularly in North America, to help it recover from last year's profit slump.A CONSERVATIVE OUTLOOK Executive Vice President Seiji Kuraishi acknowledged that Honda's expected currency hit of 95 billion yen was based on a "conservative" yen forecast, adding that growing costs to create next-generation cars would also impact earnings. "Our costs are rising to develop new technologies which will be needed in the future, like automated driving functions and electric cars," he told reporters at a results briefing.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.
