Mazda3 Skyactiv-Hybrid and CNG Concept shown in Japan

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we're told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.

2019 Mazda MX-5 Miata First Drive Review | More power is the icing on top

SAN DIEGO — When Mazda announced that the 2019 Mazda MX-5 Miata was getting a serious increase in power, I was both excited and nervous. I was excited because more power is always exciting, and it was no insubstantial increase. At 181 horsepower, it's the most powerful production Miata ever offered, beating out turbocharged Mazdaspeed Miata's 178 horsepower. Plus it has more revs to play with. But what had me worried was whether this power would mess up the friendly, playful character of the Miata. The 155-horsepower 2.0-liter engine is just about perfect, almost universally loved by the Autoblog staff and other reviewers, with good midrange torque and short gearing that always made it feel quick in nearly every rev range. It felt like the right amount of power for the chassis, too. There was just enough to get it loose without working too hard, but it wouldn't spin you around unexpectedly. I could imagine a couple of ways the new engine could affect that sweet balance, too. A bit too much power could risk some of the Miata's accessibility and predictability. It might become more serious and less fun-loving. I also feared that in pursuit of a higher redline and more horsepower, the low-end of the rev range might become painfully slow. Honda owners know this feeling whenever their VTEC-equipped screamers drop out of the aggressive cam profile, and the Toyota 86 and BRZ suffer from an awful lack of torque right in the mid-range that doesn't recover until nearly redline. All of this was on my mind when the assembled reviewers were briefed by Mazda engineers about the car. It started out like most presentations, with a brief rundown of the goals of the car and what Mazda has done with the model so far. Then came a chart showing the power curves of the NC, current ND, and the 2019 model, and my fear of a loss of low-end grunt dissipated. The amount of power and torque over engine speed is nearly identical between the old and new ND Miatas right up to around 4,500 rpm. And then from there, the 2019 continues making more power all the way to its 181-horse peak at 7,000 rpm, 500 rpm higher than the previous model's redline. This was a good sign. Mazda managed to get these gains with no sacrifices through many small upgrades. The throttle body is wider with a slimmer throttle plate, the intake manifold has longer runners and dual paths, and the intake ports are larger.

2020 Mazda3 gets five-star overall rating from NHTSA

Mazda is adding another figurative piece of silverware for its heralded Mazda3, this time in the form of a five-star overall rating from the National Highway Traffic Safety Administration. The designation applies to both the hatchback and four-door sedan, and front- or all-wheel-drive versions. Mazda’s entry-level compact, which underwent a dramatic redesign for 2019, notched five-star ratings across the board: frontal crash, side crash and rollover crash tests. The Mazda3 has also been named Top Safety Pick+ by the Insurance Institute for Highway Safety, with top scores on all crash tests and ease of use of the LATCH child-seat system, but an acceptable rating for its headlights as the only slight ding. Mazda opted to make its i-Activsense safety technology system standard on the 3 for 2020. It covers NHTSAÂ’s recommendations of having forward collision warning, lane departure warning, crash imminent braking and dynamic brake support, and it adds features like blind-spot monitoring, driver attention alert, automatic on-off LED headlights and rain-sensing windshield wipers. The fourth-generation car also got a stiffer body with a 10-fold increase in high-strength steel and a revamped suspension. Mazda sold 50,741 examples of the Mazda3 last year, which made it the automakerÂ’s No. 2 nameplate, though well behind the CX-5, which moved 154,545 units. Sales in January were off 45.7% from the prior year, when the new version wasnÂ’t yet on sale, suggesting that despite its distinctive looks and accolades from the motoring press, the Mazda3 is fighting an uphill battle against crossover-dom.
