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.

2019 Mazda3 Sedan Drivers' Notes Review | Moving on up

The Mazda3 enters its fourth iteration for 2019, replacing one of our favorite compacts on the market. As such, expectations were high for the new model. Like before, the Mazda3 is available as both a sedan and hatchback, though the big news for the new model is the available all-wheel drive system, a rarity for the class and and a feature more and more people are looking for in a car these days. At launch, power comes solely from a 2.5-liter naturally aspirated inline-four, though Mazda plans to offer additional powertrains down the line. Competitors include the Honda Civic, Toyota Corolla, Subaru Impreza, Hyundai Elantra and Kia Forte. Our tester was a well-equipped Mazda3 Premium front-wheel-drive sedan. Standard features include 18-inch wheels, LED lighting, a power driver's seat, leather seating and trim, keyless entry and ignition, dual-zone climate control, an 8.8-inch infotainment system, Bose audio, blind-spot monitoring, rear cross-traffic alert and adaptive cruise control. The only added cost to the Premium Package is $595 for the paint. All in, our tester came out to $27,990. Editor-in-Chief Greg Migliore: The Mazda3 is the sportiest in the segment and, as far as I'm concerned, it's dead-even with the Honda Civic for the top spot in the looks department. The steering, brakes and suspension all feel dialed-in and quick. Many compacts are sedate. The 3 makes you want to track it. The suspension is stiff enough that non-enthusiasts might prefer something else, though it's not abusive. The naturally aspirated four provides just enough getup. Mazda is good at the minimalistic approach. Tune a car well, make it look sporty, and don't try to overcompensate with horsepower. This thing looks great inside and out. For the price, you can't beat it. The cabin has the appearance and feel of a premium sedan, with pleasing materials and an enveloping cockpit. With a creased hood and huge, blacked-out grille, the 3's front end has a contemporary style with old-school panache. I might like the hatch better because it's a rarer body style. Still, this sedan is a well-rounded, sporty execution and a great value. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Associate Editor Joel Stocksdale: Since its reveal at the Los Angeles Auto Show, the 2019 Mazda3 has been my most anticipated car of the year, as well as the one I've been most worried about.
