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 will sell a removable MX-5 Miata hardtop only to racers

Before the advent of the power-folding hardtop NC or the newer MX-5 RF targa, you could buy a fiberglass hardtop to plop on your soft-top Miata. Expensive when new and rather rare, they command top dollar now. And moreover, Spec Miata racers have always sought them for use in that series. Now, what's old is new again, sort of. Mazda Motorsports will sell a removable hardtop for $4,420, but there's a catch. You have to purchase a MX-5 Cup Global race car to order one. A Mazda spokesperson confirmed to Autoblog that non-Cup racers won't be able to purchase a new hardtop for their ND – and furthermore, since it's oddly shaped to clear the rollcage, they might not want to. Second-hand, who knows? Even though it's pricey, it'd offer a different experience than you get from the sexy RF. Related Video: Motorsports Mazda Convertible Racing Vehicles Performance mazda mx-5
