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 Miata RF gets price bump for 2019

Over the past couple of months, Mazda has been releasing information about updates for the 2019 model year of the MX-5 Miata. We got details about the car's 2.0-liter I4 making 181 horsepower and 151 pound-feet of torque. The car also gets a telescoping steering wheel, new door stops, updated cupholders and seat levers, standard rear-view camera and 17-inch wheels. Later, we learned the new Miata would also be a smidge more efficient. Now, Mazda has announced pricing for the 2019 Miata RF. Going on sale in August, the 2019 Miata MX-5 RF starts at $33,240 (including $895 in destination fees) for the Club trim level with a six-speed manual transmission. That's a price increase of $435. That doesn't seem so bad when you consider the extra 26 horsepower and higher redline. The Club 6MT can also be optioned with Brembo brakes and BBS wheels for an extra $3,770, or the Brembo/BBS/Recaro package for $4,670. The MX-5 Club with six-speed automatic comes with paddle shifters and sport mode for $33,840, but isn't available with the Brembo/BBS packages. The i-ActiveSense package, which includes features like Smart City Brake Support and lane-departure warning is a $450 option for the Club 6AT. MSRP for the Grand Touring trim starts at $34,230 with a six-speed manual transmission, which is $585 more than the outgoing model. The new GT-S package for the Grand Touring 6MT adds $750, and comes with a front shock tower brace, limited-slip rear differential, Bilstein dampers and a hand-painted black roof. The Grand Touring with six-speed automatic goes for $35,305. Auburn Nappa leather adds another $300. In terms of exterior colors, there are three premium options to choose from, each with its own added price. The gorgeous Soul Red Crystal tacks on another $595 to the price of the Miata RF. Machine Gray Metallic adds $300, while Snowflake White Pearl Mica costs $200. Pricing for the soft-top version of the 2019 Miata hasn't been announced yet. Related Video:

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.
