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.

5 stars in Euro NCAP crash tests for 5 new cars available in U.S.

Seven new cars have received a full five-star rating in the latest Euro NCAP crash tests. Of these, five are available in the United States: the Audi E-Tron, Lexus UX, Toyota Corolla, RAV4 and Mazda3. The Renault Clio and the Volkswagen T-Cross also took part, also receiving five stars. The Mazda3 hatchback was the fourth car in Euro NCAP history to reach an adult occupant protection score of 98%, after the Volvo V40 and XC60 and the Alfa Romeo Giulia. No NHTSA ratings for the Mazda3 or the Audi are yet available, but the Lexus and the Toyotas have all received five-star NHTSA safety ratings as well. Those three were tested as hybrid variants by Euro NCAP. Audi's first fully electric vehicle, the E-Tron, scored 91% in Euro NCAP's adult occupant rating, with unavailable knee airbags bringing down the score. The Mazda and the Toyotas offer them for the driver only, and the Lexus has the passenger's knees covered as well. The Lexus UX managed a 96% adult occupant score, close to the Mazda, and it provided better pedestrian safety (82%) than the Audi (71%), despite neither, or none, of the test vehicles having an active hood to catch pedestrians. As for the Toyotas, the Corolla, tested in both sedan and hatchback guises, scored 95% for adult occupant safety, with the RAV4 a couple notches down at 93%. Still, the five-star rating means all these vehicles are a very safe choice in their respective classes. Michiel van Ratingen, secretary general of Euro NCAP, states how important it is that even family hatchbacks perform well and have the latest safety tech available. "It is encouraging to see that all manufacturers did well, regardless of type of powertrain or class of vehicle tested," said van Ratingen. "New cars on the market continue to offer more advanced technology as standard, systems that were not even considered an option a few years ago." More crash test videos are available on Euro NCAP's YouTube channel. Audi Lexus Mazda Toyota Car Buying Safety audi etron lexus ux

New Mazda3 looks just like Mazda Kai concept in spy photos

Just a couple of weeks before the official reveal, one of our spy photographers caught the next-generation Mazda3 out testing in minimal camouflage. The car was a hatchback model, testing alongside a VW Golf and Audi A3, and was only wrapped in thin vinyl. As a result, we can clearly see that the new compact Mazda hatchback looks just like the stunning Kai concept from last year's Tokyo Motor Show. The car features effectively the same nose and profile of the concept. The main grille is larger than the current model, and it leans forward aggressively. The windshield is very low and sleek. The rear portion of the car is dominated by the very thick C-pillar that leans far forward, augmenting the car's athletic stance. The window sill at the rear kicks up sharply, and the rear window doesn't wrap around or bulge out, giving the car a very tight, taut shape. It's not just the outside of the 3 we get to see. We get a good look at the interior. It also looks very much like the Kai's interior, with the focus being the driver. The gauges are flanked by air vents that blend into the shape of the instrument binnacle. The rest of the dashboard is left as uncluttered as possible. The climate controls and vents all reside in the same long horizontal plane. The infotainment screen, which appears to be touch-sensitive based on one spy photo, is canted toward the driver. Mazda's rotary controller does return, as seen in the center console. Also in the center console is the manual shift knob, which we expect, or at least hope, will continue to be available in the U.S. We'll have answers to all our questions about the Mazda3 at the end of this month when it makes its debut at the L.A. Auto Show. We'll also see the sedan version of the car. The powertrain is the biggest mystery at the moment. Mazda showed the Kai with the Skyactiv-X engine, Mazda's spark-controlled compression-ignition gasoline engine. We've driven a development car with the engine, and Mazda seemed to intend the new Mazda3 to use it, but we're not sure if the engine will be ready for the car's launch. If not the Skyactiv-X engine, or perhaps in addition to, Mazda will probably use versions of its current engines. It could carry-over the naturally aspirated 2.0-liter and 2.5-liter four-cylinders currently used. The latter may use the cylinder deactivation now used on the Mazda6 and CX-5. We would love to see the company finally offer the turbocharged 2.5-liter engine from the Mazda6, CX-9, and now CX-5.
