Mazda explains the thinking behind the MX-30's small battery pack

Mazda's first production-bound electric car, the MX-30, relies on a 35.5-kilowatt-hour lithium-ion battery pack for power. That's relatively small, but the Japanese firm argued it's exactly what the model needs to let motorists drive electric while keeping their environmental footprint in check. Christian Schultze, head of Mazda's European research and development center, told Automotive News Europe the MX-30's battery is responsibly-sized. He explained engineers took a variety of factors into account when debating kilowatt-hours, including how much energy is required to build the pack, how much electricity is needed for a full charge, and the environmental impact of replacing the battery, which Mazda expects could be necessary after the MX-30 has covered about 100,000 miles. Sticking with a smaller pack yields total CO2 emissions on par with a turbodiesel-powered Mazda3. In contrast, using a 95-kilowatt-hour battery (which is close to what Tesla's bigger models use) would have increased the MX-30's life-long CO2 output considerably by requiring more energy to build, and needing far more electricity to achieve a 100% charge. We're not quite sure that math or battery longevity assumption hold up under scrutiny. In any case, small is the direction Mazda decided to go. The trade-off is that the MX-30 (pictured) is expected to drive for about 124 miles between charges, and that figure was achieved on the hugely optimistic WLTP testing cycle; real-world mileage will be lower. That's hardly a jaw-dropping number, and the crossover doesn't qualify for the coveted long-range label, but Schultze told British magazine Autocar it's more than enough to cover the daily transportation requirements of the average European motorist, which stands at a total of 31 miles. That's significant, because Europe will be one of the MX-30's key markets. Deliveries are scheduled to begin in early 2021. Mazda hasn't announced whether it will sell the MX-30 in the United States, or if it will wait until it has a longer-range electric car to enter the segment.

Mazda teases electric car again with peek at interior

Mazda is again touting the new electric vehicle it plans to reveal at the Tokyo Motor Show, this time teasing it from the inside. A 15-second video homes in on features found on the center console, namely, the blocky shifter for the automatic transmission, a large, knurled rotary dial for infotainment control, and a smaller dial we'll assume is for volume control. As for what else we can make out, if we were to guess, we'd say the slick surface to the right of the shifter is a screen. It'll be interesting to see how Mazda designers filled the space between the seats, but we're surprised Mazda went with such a substantial shifter; this being an EV on a new, dedicated platform, designers could have minimized the focus on shifting and opened up a host of other uses.  A brief press release informs us that Mazda's worked to liberate the cabin from structural clutter, though. The brand says the interior is "designed to give occupants a feeling of being 'enveloped in openness,'" and that the "goal [is] to make spending time in the car a comforting experience that allows customers to be themselves." Empty spaces throughout the center console "create a connection between the driver and passenger seat areas," so perhaps what looks like a free-floating console demo section in the video is what the unit will look like in the car. Elsewhere, the EV will feature eco-friendly materials. The EV isn't expected to make it to America, its powertrain designed to satisfy residents of particularly dense urban environments. The running gear should stick close to the drivetrain developed for the e-TPV prototype, meaning a 35.5-kWh battery powering a single electric motor at the front axle producing 138 horsepower and 195 pound-feet of torque, and a single-speed transmission. Range is thought to be around 120 to 150 miles on a charge. The onboard charger can handle 6.6-kW home charging and 50-kW rapid charging. Eventually, a range-extender version with a rotary engine should join the lineup; Mazda said it chose a rotary because even though it's less efficient than competitors' ICE range extenders, it's so much quieter. The debut of what everyone expects to look like a crossover happens on Oct. 23.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
