Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

At least 15 states jockeying for Toyota and Mazda factory jobs

Just a few weeks ago, Mazda and Toyota announced a partnership that would lead to an all-new $1.6 billion plant here in the United States. The plant will build EVs and is expected to employ roughly 4,000 people directly while creating thousands of indirect jobs through suppliers, shipping and more. The Detroit Free Press reports that as many as 15 Midwestern and Southern states are understandably interested in striking a deal with the automakers. Most of the states already have ties to the auto industry. While the Midwest has traditionally been home to auto manufacturing in the United States, in the past 25 years or so, the South has made a big push, offering tax incentives and a union-free workforce. Alabama alone is home to facilities from Honda, Hyundai, Mercedes-Benz and Toyota. Others house a burgeoning tech or manufacturing industry ripe for the picking. Freep breaks down the pros and cons for each state, with much of the focus being on supply chains and a reliable and plentiful workforce. The latter is of particular concern in states like Alabama and Michigan that already have a big auto industry. Toyota may feel those areas have already been tapped for talent. Most of the states are along or adjacent to Interstate 75 and its extended roots, so others like Texas and Iowa will have to fight hard if they want this facility. It's only been a few weeks, though. With manufacturing jobs in such great demand and elected officials eager to show they're seeking them for their states, it wouldn't be surprising if a few more joined the fray.

R&T chases down a burglar in the million-mile Miata

Is the answer always Mazda Miata? We discussed this in passing on the Autoblog Podcast earlier this week, and most assuredly the answer is "no." For example, the little MX-5 would be a terrible people carrier, and it'd be useless off road. You can't really tow anything of substance with it, either. Still, if push came to shove, it's satisfying to know that the diminutive roadster could eke out a career as a chase vehicle for the police.
That fact was proven when Road & Track editor Chris Cantle did something that he himself recognizes as "stupid." Upon returning home, Cantle discovered a "twenty-something" actively burgling his home. The resulting story is easily one of the more entertaining episodes to come out of the 1990 MX-5's service to the team at R&T and, we're guessing, will be one of the highlights of the Million-Mile Miata challenge.
Be sure to head over to Road & Track for a full retelling of the chase from Cantle, as well as a follow-up on the saga.
