Will Mazda show the next Miata's chassis in NY?

Mazda is being very sneaky about what it is bringing to the New York Auto Show, and it might have something to do with the next-generation MX-5 Miata. Australian website Motoring.com.au spoke to a company insider who told it that at least the chassis for the roadster would debut in Manhattan. The rumor goes that the show will act as the kickoff for the PR campaign for the new model.
We contacted Mazda USA PR Director Jeremy Barnes to find out more, and he would neither confirm nor deny the rumor. "Just because you read it on the Internet doesn't mean you should repeat it," he said to Autoblog. That's not exactly an outright, No.
Supporting evidence that the new drop top might be appearing in the Big Apple includes Mazda's plan to celebrate the model's 25th anniversary at the show. It's bringing 15 cars from the first three generations to display. "It will be absolutely worth attending the New York Auto Show if you're a Miata fan," Barnes said. That at least hints that there might be something he's not telling us. Otherwise it's a lot of sizzle without much steak.

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:

Toyota delays Mexico plant as it plans U.S. plant with Mazda

TOKYO — Toyota will push back the start of operations at its scheduled new plant in Mexico, to the first half of 2020 from the initial plan of 2019, the company said on Thursday. Japan's top automaker had initially planned to start building the Corolla sedan at the $1 billion Guanajuato plant but said last week it would switch production to a new U.S. factory to be built with Mazda. Toyota said the delay was necessary to adjust its supply chain in Mexico to produce the Tacoma pickup instead of the Corolla compact car. That factory could also build sport utility vehicles, a Toyota spokesman in Mexico said last week. "With the production model change to the Tacoma pickup, the start of production will consequently be in the first half of 2020," a Toyota spokeswoman said. "However, we will make our utmost effort to advance the timing in order to minimize the impact to suppliers and the local community." Until the scheduled start of the joint venture plant with Mazda in 2021, Toyota will supply the Corollas that were initially slated to be built in Mexico from its factories in Mississippi and Japan, the company said.Related: Mazda-Toyota partnership has us dreaming of a rotary hybrid Reporting by Makiko YamazakiRelated Video:
