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.

RingBanana Miata breaks 9-min Nurburgring barrier

The RingBanana is a cheap Mazda MX-5 Miata on a screaming mission: to lap the Nurburgring in under nine minutes. And let us emphasize the word "cheap." The team wanted the least expensive Miata they could find that still ran, and then wanted to spend the least amount of money possible in order to hit their target mark. We don't know how much they spent on the Ringbanana, but they were so indiscriminate about the purchase that they don't know what year the car is. They only know that it's got 90 horsepower, green springs, Fulda tires, and "it's completely crap." After setting a base lap of 9:21.8 the guys behind the project figured they'd have a fair bit of work. Turns out a new set of Kumho V70A semi-slick, road-legal race tires paired with Gabriel Pirana's driving is all they needed. With just that mod Pirana set a lap time of 8:59.9, and that was while having to deal with one spot of slow traffic that was getting around a stricken car. According to Wikipedia, this puts them between a 2010 Range Rover Sport Supercharged and a 2007 Chevrolet Cobalt SS. Even though the team achieved its goal on its first attempt, the Ringbanana game isn't over – there's probably a suspension mod in the near future while the guys figure out just how quickly they can go. The video above does a good job of showing just how fun it can be driving a slow car fast.

Will Mazda sell diesel hybrids in Japan in 2016?

Could the "Zoom Zoom" automaker start making hybrids that go "glug glug glug"? Mazda, known for its fuel-efficient Skyactiv engine line, will be the first Japanese automaker to make a diesel-hybrid vehicle for Japan and Europe. According to the Yomiuri Shimbun, Mazda may start making its oil-burning hybrids as soon as 2016, and the powertrain may reach fuel efficiency levels of as much as 95 miles per gallon (one the more lenient Japanese driving cycle). That'd make such a vehicle line about 30 percent more fuel-efficient than standard diesels and about eight percent more fuel efficient that the Toyota Prius C compact hybrid (known as the Aqua in Japan). Mazda has been dismissive of hybrid and electric powertrains, instead focusing on Skyactiv technology to maximize fuel efficiency from conventional gas-powered engines. Diesel powertrains account for about half of the light-duty vehicles sold in Europe each year, while Japan's diesel sales of 76,000 vehicles last year were about three times as many as were sold there in 2012. In January, Mazda said that it would delay the introduction of its Skyactiv-D diesel engine from what was to be a spring 2014 debut. The reason was to fine-tune the engine's performance/fuel economy balance. Mazda representatives didn't immediately respond to a request for comment from AutoblogGreen about the diesel hybrids.
