2016 Mazda MX-5 Miata shows off perfect 50/50 weight balance

When I attended the first drive event for the Japanese-spec 2016 Mazda MX-5 Miata in Spain earlier this year, I was blown away – and not just by the car. I was blown away by the charts and graphs Mazda's engineers brought along, showing how every little facet of the ND Miata was finely tuned for pure driving perfection. It's like rocket science. Only cooler. One of the most important parts of the Miata package is its weight distribution. The 2,332-pound roadster must achieve a perfect 50/50 balance, with a driver inside. That's not easy. But it has to be done. Only the best for the Miata. In this video, Mazda shows off the Miata's balance by putting it on an aluminum balance beam, to see if the car stays perfectly centered. You can probably guess the outcome, but watching it all take place is super cool, especially with commentary by Mazda engineer Dave Coleman and MX-5 program manager Rod McLaughlin. How does the 50/50 balance help the Miata's handling out on the road? You'll have to wait until the embargo on driving impressions for the US-spec car lifts. We'll have the full scoop at 3:01 AM Eastern on Monday, June 1. In the meantime, get a sneak preview of the new Miata in the video below. Autoblog readers got a closer look at the 2016 MX-5 at our Cars & Coneys meet-up, and as you can see, the excitement for this car is definitely real.

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.

2020 Mazda3 hatchback starts at $24,620, a $100 increase

Car and Driver got the scoop on some 2020 Mazda3 pricing, and anyone waiting for the new model year had better bring more money. The Mazda3 sedan goes up by $500 to $21,500. After the $920 destination charge, that's a total of $22,420. On the sedan, however, the extra dosh pays for extra equipment. Every sedan trim gets Mazda's i-Activsense driver assistance tech, meaning adaptive cruise control, automatic emergency braking, blind-spot monitoring, lane-keep assist, and lane-departure warning. The i-Activsense suite had been an option the sedan's entry-level trims. The Mazda3 sedan in Select guise, one step above the entry-level model, increases $100 to $23,620. Starting price for the front-wheel drive 2020-model-year hatchback comes in at $24,620 after destination. C/D says that's a $1,020 bump, but we believe that figure is an error. Based on the fact that Mazda's U.S. pricing rounds off to the nearest hundred and destination is $920, it seems more likely the $24,620 price includes destination. In that case, the 2020 Mazda3 hatch only goes up by $100. The five-door models don't get any more equipment, but Mazda say's there's a new finish for the wheels on the top-tier Premium trim. All other trims hold steady. The 2.5-liter four-cylinder with a square 186 horsepower and 186 pound-feet of torque remains the sole engine option, a six-speed automatic is the standard transmission on all trims, the hatchback in Premium form offering a six-speed manual option. Buyers of the entry-level sedan are stuck with front-wheel drive, while every other trim offers all-wheel drive for $1,400. The sedans should hit dealerships this month, and the hatchbacks will roll in come September.
