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 16X rotary engine two years away, will arrive in all-new model

We last reported on Mazda's next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine's development had been around way before that final car left the production line in Japan, last year.
We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8's engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.
What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years' time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list...

25th Anniversary Edition Mazda MX-5 Miata sells out in 10 minutes

Looking to buy one of the limited-edition 25th Anniversary Mazda MX-5 Miata roadsters? Well, you're too late. According to Mazda, all 100 examples of the darling two-seater have sold out - and it only took 10 minutes.
On Tuesday, Mazda opened its pre-order site for the limited-run Miata, and had intended to keep the site running until May 31, or until 250 customers were registered, whichever came first. Just 10 minutes later, 250 people had signed up. Now, Mazda will contact those folks, and the first 100 that are verified will be given the opportunity to pre-order the unique MX-5. "Upon verification of purchase intent and transmission selection, the customer's information will then be forwarded to the dealership of their choosing to finalize the transaction," Mazda said in a press release.
The 2015 MX-5 Miata 25th Anniversary Edition models will arrive at dealers this summer, retailing for $32,205 with the six-speed manual, or $32,655 for those desiring the automatic transmission. Based on the PRHT (Power Retractable Hard Top) model, the limited-edition Miata adds Bilstein shocks, a Soul Red metallic paint job (the same found on the gorgeous Mazda6) with a contrasting black roof, gunmetal wheels and an off-white leather interior. Special badging will be found inside the car, and buyers will also be treated to a custom-crafted Tourneau watch and a display winder box.
