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.

Hyundai, Mazda and Ford offering support to victims of Colorado flooding

Hyundai, Mazda and Ford have initiated programs to aid victims of the recent floods across Colorado. Hyundai is stepping in to give help directly to drivers, offering those with flood-damaged vehicles a $750 credit on a new Hyundai. "At this stressful time, the last thing flood victims should be concerned with is how they are going to replace their water-damaged or destroyed vehicles," Dave Zuchowski, executive vice president of Hyundai's American sales, said.
The Hyundai program will run from September 18 through the end of October, and will cover all citizens in counties declared disaster areas by FEMA. Residents will need to provide proof of residency and a letter from their insurance company describing the damage to their vehicle.
Mazda, on Friday, announced that it'd be donating $25,000 to the American Red Cross and a further $15,000 to the Humane Society of Boulder Valley, in the name of disaster relief. Mazda's President and CEO, Jim O'Sullivan, said, "The flooding across the states of Colorado, Texas and New Mexico has been absolutely devastating for not only the people living there but their four-legged loved ones as well. Mazda hopes that those in need can get the help they deserve through such great organizations as American Red Cross and Humane Society of Boulder Valley."

2019 Mazda3 Hatchback AWD Premium Second Drive | Gushing about an exceptional car

The 2019 Mazda3 Hatchback is quite simply one of the best cars I've ever driven. During my week with one, specifically a range-topping Premium package version for $31,335, I struggled to come up with bad things to say apart from elements like rear visibility and back seat headroom that are directly related to its distinctive, avant garde design. That's an acceptable tradeoff in my book. So many of the new 3's elements can serve as a measuring stick for other cars. Not just its specific compact hatchback/sedan class, but all other cars, period. I had the Mercedes CLS 450 at the exact time, a car I deeply appreciate and that cost $69,000 more, and yet it was a struggle to decide which I wanted to drive. Perhaps not surprising given the 3's history, but the measuring stick is set first by the handling. It dances between corners with composure and feedback that you just don't get in cars any more Í– let alone at this price point. This is a car you feel through your butt, your heels on the floor and your hands on the wheel. Everything is just so right. And it should be noted that I came to this conclusion before remembering that Mazda switched to a cheaper, less sophisticated torsion beam rear suspension for this latest model. Perhaps you can tell the difference driving 10/10ths at a test track, but in the real world, I certainly didn't notice or log a complaint. Grip is superb. Even when the tires gave way a bit on my mountain road evaluation route, there was only a bit of squealing and it resolutely whipped itself through hairpins with shockingly little understeer for a front-drive-based car, helped no doubt by its all-wheel drive system. It would be interesting to see how much understeer the front-drive versions allow, and whether AWD is mitigating torque steer given the 3's not-insignificant power. As it is, the 3's standard 2.5-liter four-cylinder produces 186 horsepower and 186 pound-feet of torque, which is substantially better than virtually every other base engine in the segment. Its throttle response should be copied by everyone, as should the steering. OK, maybe not Porsche, which I keep finding myself drawing comparisons to whenever experiencing a new Mazda. Take that as the compliment it seems to be. I'd also like to note that the 3 has a six-speed automatic transmission rather than an easily confused eight-, nine- or eleventy-speed unit. Or a damn CVT.
