Mazda going back to oval grille with next MX-5 Miata

The original Mazda MX-5 Miata was distinguished by an oval grille - a design trait that gradually evolved into the smiling cat face on the latest model. But Mazda, according to the latest intel, is planning on returning to that oval grille with the new model in the works.
The revised grille will cap a slightly longer form than models past, while still keeping weight down to a minimum. The stretched wheelbase was reportedly adopted in order to meet the requirements of Alfa Romeo, which is jointly developing the new platform together with Mazda for use on a new roadster of its own.
The new Miata is expected to adopt the 1.5-liter Skyactiv four found in the Mazda3, albeit returned to rev higher and deliver more power and torque, mated to either a six-speed manual or automatic. The Alfa version, meanwhile, is expected to use a 1.4-liter turbo four with a dual-clutch transmission. Sources anticipate the new MX-5 to debut first, possibly at the 2015 Chicago Auto Show a little less than a year from now.

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.

Mazda begins building Mazda3 in Mexico for US

With fluctuations in international currencies and rising shipping costs to take into account, foreign automakers can't get away with building cars overseas and selling them in North America as easily as they used to. Particularly with inexpensive mainstream models. And given the benefits of cheaper labor and free trade under NAFTA, many have opted to assemble their cars for the North American market in Mexico. That's why the likes of Toyota, Mercedes and BMW have all opened plants in Mexico. And now Mazda has followed suit.
Ground was initially broken for Mazda de Mexico Vehicle Operations at Salamanca in the state of Gunajuato back in 2011, but production has just now gotten under way. The first vehicle to roll off the line? A Mazda3 sedan destined for the United States. Soon, the plant will begin production of the next Mazda2 as well, selling it alongside its larger counterpart across the Americas and in Europe as production expands to 230,000 units annually.
