2016 Mazda MX-5 Miata first engine shot revealed

We've dug deep for just about every scrap of 2016 Mazda MX-5 Miata info available out of the car's California reveal celebration, but powertrain particulars have been especially hard to come by. While we still don't have engine specifications, the folks over at Autoweek have scored a nice scoop - the first underhood photos of one of the display cars.
In the image above, the ND-generation Miata is clearly shown to be powered by a Skyactiv inline four-cylinder, as expected, but its displacement remains unclear. The engine is most likely either the 2.0-liter Skyactiv-G engine offered in low-end Mazda3 and CX-5 models or the 2.5-liter Skyactiv-G found in those same vehicles' upper trims. In those iterations, the 2.0-liter generates 155 horsepower and 154 pound-feet of torque, while the larger-displacement engine nets out at 184 hp and 185 lb-ft. There is no sign of a turbocharger, a feature rumored to be fitted to at least one test mule. There has also been previous rumors of a 1.5-liter Skyactiv engine, possibly for overseas markets.
The 2.0-liter strikes us as the most likely scenario, particularly as Mazda has worked diligently to save every gram in the new car, dropping a pledged 100 kilograms (220 pounds) over the current model, even while adding content. It's entirely possible that the alleged turbo car was, in fact, a mule for the Miata's Alfa Romeo sister car, which is expected to have a wholly different powertrain. Or it could simply be a second engine option for an eventual Mazdaspeed variant, perhaps.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

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.
