Mazda MX-5 GT gets green light

The Mazda MX-5 Miata is as popular around the Autoblog offices as Kate Upton posters are around fraternity houses. Few staffers have much criticism for Mazda's ubiquitous roadster, and fewer still aren't overjoyed when one arrives in their driveway. So you can imagine how a report from Auto Express about a more potent MX-5 model is going over in our offices today.
The new model, which was shown in concept form as the Mazda MX-5 GT at the Goodwood Festival of Speed, has a slight catch, though. First, we have absolutely no idea if Mazda will bring the MX-5 GT to the US. Secondly, and perhaps more problematically, this isn't a production car - it's a kit from the team at Jota Sport.
Now, to be fair, the kit doesn't sound like a bad thing. It bumps the UK-spec 2.0-liter, 157-horsepower engine up to 203 hp thanks to a sports exhaust and a revamped ECU (46 horsepower from an ECU and exhaust in a naturally aspirated car?). To make the little Miata even more agile, Jota has also fiddled with the suspension. AE doesn't mention things like the grippy tires or Recaro seats that were found on the concept, though.

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.
