The redesigned 2019 Mazda3 moves way upscale

Mazda didn't lie — the 2019 Mazda3 is a gently reworked production version of the Kai concept shown at last year's Tokyo Auto Show. In hatchback and sedan forms, you'll still quickly peg this a Mazda3. The dimensions barely change: The wheelbase grows by an inch, but the hatchback width and length carry over, while height decreases by an inch; the sedan is the same width but 3.2 inches longer and 0.7 inches lower. Nevertheless, the look and details have evolved throughout, yielding a much more potent and piercing hatchback, and a more sophisticated, accomplished sedan. Instead of using hard shoulder and swage lines to "draw" contour onto a flat profile, Mazda designed a car with contours that create real shoulders and hips. Shedding the illusion of surface depth for reality redefines the look and presence of the Mazda3. The new model erases the hash of lines and embossed panels in back of the current car so that the S-curved hatch has only its shutline for framing. After that, the highlights enhance the theme. On either side of the larger grille, single-lens headlamps get new accents; instead of a just plain silver bar, streaks of amber turn signals decorate the more dimensional units. The contoured taillamp housing holds highly structured, highly embellished twin circles that probably look even more sinister at night. On the sedan, those naughty taillights are surrounded by a refined rear valance with a more angled, muscular lip along the trailing edge. It's the same inside, a design based on results of Mazda's in-depth studies of human mechanics. The flatter instrument panel stresses clean lines along the horizontal. Trimmer steering wheel spokes with silver buttons line up with the central span across the dash housing the climate control buttons and vents. The new shift panel sits higher and more forward, making it easier for the driver to move a hand from the steering wheel to the lever. To raise perceived luxury, the center tunnel trim is a clear layer laid over a laser-engraved black layer, said to produce a "look of deep transparency," and similar to the effect found on the new BMW X5 and X7. The cupholders are now in front of the shifters, and the armrest is longer. There's no mention of that digital gauge cluster that leaked earlier this year, though. Buyers who opt for fabric will get a new "Greige" hue, a mix of gray and beige. Mazda designed a new leather grain with creases of varying depths and shapes depending on where it's placed.

50 engineers kept the rotary alive at Mazda for 8 years

The Mazda RX-Vision concept is one of the standouts at this year's Tokyo Motor Show thanks to a drop-dead gorgeous design and a revival of the Wankel engine. The fact that the rotary is still in development at Mazda is thanks to a dedicated group of 50 engineers. According to Automotive News, their dream for the last eight years has been to bring this storied engine design back to the street. It won't be easy. Because of its design, the rotary suffers from poor fuel economy and high emissions. Making the challenge even harder, Mazda reportedly only gives them a small budget, but they continue to chip away at the problem. "These 50 engineers want to develop the rotary engine, therefore they joined Mazda," company research and development boss Kiyoshi Fujiwara told AN. "If I stop the rotary engine, probably they want to leave." For the Skyactiv-R under the RX-Vision's svelte hood, the team reportedly started from the 16X rotary project. Dating back to 2007, that 1.6-liter engine was supposed to improve torque and fuel economy thanks in part to direct injection. After additional development, insiders even suggested that the engineers might have finally solved the powerplant's issues. However, Mazda never put the mill into production, and the RX-8 remains the company's last Wankel-powered model to be offered in showrooms. "We have a dream that one day, this design with a rotary engine will achieve a level that customers will accept," CEO Masamichi Kogai said to AN. Mazda is quite clear that the RX-Vision might never go on sale without a suitable rotary. Although if it does see production, the coupe would likely use a stiffened version of the Miata's chassis, AN reports. Before anyone can place an order, these 50 determined engineers still have a lot of work ahead of them. Related Video:

Mazda6 diesel is coming, too, Mazda promises (again)

As we noted our piece earlier today about the CX-5 diesel, we've been waiting for Mazda to bring its Skyactiv-D engines to market for years. Tripped up by an emissions certification nightmare that caused delays and resulted in lackluster power and fuel economy numbers, they're late to the party. In the CX-5 diesel, it's also a questionable proposition at almost $4,000 more than the much more powerful CX-5 Turbo. But today, Mazda's U.S. president confirmed to Autoblog that the diesel engine would make its way into the 6. Like the CX-5, it'll only be offered with all-wheel drive and only on the top Signature trim level. Unlike the CX-5 diesel, which goes on sale in July, we don't know when the Skyactiv-D-powered 6 will go on sale. But it seems like later this year is a good bet. How much longer can Mazda wait, really, once the CX-5 diesel is on sale? The diesel Mazda6 will use the same 2.2-liter engine as the CX-5. It'll probably offer the same power figures – 168 horsepower at 4,000 rpm and 290 pound-feet of torque from a low 2,000 rpm, with a 5,500-rpm redline. The fuel economy bonus for choosing a diesel over the turbocharged gas engine should roughly parallel the difference in the CX-5: about 5 mpg in the city and 3 mph on the highway. That said, we don't know the 6's EPA fuel economy numbers yet. We expect the price premium to roughly parallel the CX-5 as well, so the diesel will likely be several thousand dollars more than the gas turbo engine in the same Signature trim. These are educated guesses, of course, and when we have firmer numbers or solid estimates from Mazda we'll let you know.
