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.

First batch of 2016 Mazda MX-5 Miatas lands in US [w/video]

Have you been patiently awaiting the arrival of the all-new 2016 Mazda MX-5 Miata? Then we're glad to report that your patience has paid off. In fact, even if you haven't been so patient, we're still glad to report that the wait is finally over, as the first batch of the new Japanese roadsters has arrived on American soil. The initial batch of several hundred MX-5s arrived at the port of San Diego from the factory in Hiroshima on board the Phoenix Leader, a 636-foot vehicle carrier ship registered in Panama and operated by Japanese shipping giant NYK Lines. The vehicles are currently being processed at the SoCal port, with deliveries to commence "in the next several weeks," according to Mazda in the brief statement below. The fourth-generation Miata, designated generation ND, mad its global debut at the Paris Motor Show, and its US debut at the LA Auto Show. Production commenced in Japan this past March. The new roadster arrives in US showrooms with a 2.0-liter four-cylinder engine (the smaller 1.5 kept away from these shores), a six-speed manual (replacing the previous five-cogger), a folding soft roof (no retractable hard top this time), and a starting MSRP of $24,915 (plus an $820 destination charge). That, of course, is for the base Sport model, with higher-spec Club and Grand Touring trims also on offer. Along with the images above, you can watch footage of the vehicles driving off the ship in the video below. Might we recommend, however, muting the cheesy soundtrack and playing something more suitable over it instead. Neil Diamond's (Coming to) America ought to do the trick... today!

Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:
