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.

Perk up your Mazda Miata with BBR's new 248-horsepower turbo kit

For three decades, enthusiasts have argued whether the Mazda MX-5 Miata needs more power. For its part, Mazda seems fine with leaving the Miata as is, even reducing the horsepower from the third- to fourth-generation models, though the car lost a little weight. That's where tuners like BBR in the UK and Flyin' Miata here in the US step in, offering aftermarket solutions for those that crave a little more grunt. BBR announced today that its new 248-horsepower Stage 1 turbo kit is ready and waiting for the new 2.0-liter-powered ND Miatas, including the new Miata RF. BBR's first Miata turbo kit was released all the way back in 1990. Since then, the shop has been tuning and honing its craft, releasing ever-more potent variations its comprehensive power kit. This new version, like the previous ones, focuses not only on adding more power but maintaining the level of drivability and refinement you expect from all Miatas. The Mazda electronic safety features are retained, and the team is working on CARB emissions approval. That said, with BBR tune an ND Miata will hit 60 mph in just 5.0 seconds, roughly two seconds quicker than stock. To get the peak 248 horsepower and 236 lb-ft of torque, BBR does more than simply slap on a big turbo. In 2014, BBR began using a Mazda3 as a development vehicle in preparation for the new Miata's launch. A twin-scroll turbocharger is mounted onto a custom cast-iron manifold. A front-mounted aluminum intercooler keep things cool and doesn't require cutting up the bodywork. The engine breathes in through a K&N air filter and exhales through a stainless steel downpipe. The whole thing is controlled by BBR's Starchip / EcuTek RaceRom ECU software package. Other upgrades include silicone turbo pipes, an aluminum battery tray, a recirculating piston type dump valve, a carbon-fiber heat shield, and stainless steel oil and water lines. BBR is offering extended warranties from 12 to 36 months. In the US, the sole distributor is Flyin' Miata in Colorado. At $5,695, it's not a cheap proposition, but it is less expensive than one of Flyin' Miata's V8 swap kits. Less expensive (and less potent) performance kits are also available.

Mazda will have a new rotary concept at Tokyo show, trying to bring it to production

Despite ending production of the rotary engine in 2012, Mazda has repeatedly insisted that it's still working on rotary engine tech, and it has continued to tease a potential future rotary car with concepts, the latest of which was the RX-Vision. The company even continues to file patents on rotary tech. It seems the company is continuing this pattern, since the vice president for Mazda's European R&D center told Auto Express that it has another rotary concept ready for this October's Tokyo Motor Show. According to Auto Express, the car expands on the groundwork laid by the RX-Vision concept. In addition to revealing the existence of the concept, the executive also reiterated the fact that there's still a team in Mazda working on the rotary engine, and people are still trying to make a business case for a new rotary sports car. Auto Express expects a production car could come in 2020. The news outlet also asked if the hypothetical car would be hybridized, and the Mazda executive didn't give much of an answer beyond it being possible, though he would prefer a purely rotary-powered car. We at Autoblog think a hybrid rotary of some sort would make the most sense. It would make for an impressive halo vehicle that could be used to promote future Mazda hybrids. This would also help with the business case side of things. An electric motor, or motors, would be highly complementary to the rotary engine as well. Electric motors produce oodles of torque from down low, which rotaries don't, and the rotary engine's high-rpm horsepower would compensate for the electric motors when they've started running out of power. Not only that, but using a hybrid powertrain could help a thirsty rotary engine meet fuel economy and emissions requirements while still producing plenty of power. A hybrid system is also more possible now that Mazda is teamed up with hybrid expert Toyota. Related Video:
