Next Mazda MX-5 Miata to weigh a ton(ne), literally

Looking at recent spy shots of the fourth-generation Mazda Miata, it's obvious this sporty little roadster will grow in size compared to the current model, but it's also going on a diet. At the Tokyo Motor Show, Auto Motor und Sport sat down with Mazda executive Kiyoshi Fujiwara, who gave a little more insight into the Miata's redesign.
Fujiwara said that they're aiming for a curb weight of a tonne (metric ton), which is 1,000 kilograms or right around 2,200 pounds, for the next-generation Miata. This would make the roadster at least 300 pounds lighter than the current NC Miata, but still about 200 pounds heavier than the original NA.
There is no indication as to how Mazda will go about removing that much weight from the bigger car, but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight. Improving the power-to-weight ratio appears to be a key goal of the Mazda team, so we also wouldn't be surprised to see a more powerful engine underneath the longer hood.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Mazda announces mild-hybrid variant of MX-30 crossover in Japan

Mazda hinted its first series-produced electric car, the MX-30 introduced in late 2019, might not be sold in the United States. We could see it on our shores with another powertrain under its coupe-like sheetmetal, however. The company announced a mild-hybrid variant of the crossover during a press conference held in Japan. Technical details about the gasoline-electric MX-30 are hazy, but Mazda said it's powered by the same basic mild-hybrid system available in the Mazda3 and the CX-30. That means the drivetrain is built around a 2.0-liter four-cylinder engine and a small electric motor that captures the kinetic energy generated while braking. It uses this electricity to power the car's electronics, and it injects it into the driveline to deliver bursts of extra power. Fuel economy and performance figures haven't been released yet. We expect the mild-hybrid model will be quicker than the heavier electric version, and its driving range will be appreciably greater. The electric model is equipped with a relatively small, 35.5-kilowatt-hour lithium-ion battery pack that delivers a 124-mile range. Mazda explained using a smaller pack yields total CO2 emissions on par with a turbodiesel-powered Mazda3. The biggest visual difference between the two variants is an e-Skyactiv-G emblem on the hatch. Both model wear the same sporty design characterized by a steeply-raked roof line and a set of rear-hinged half doors reminiscent of the rotary-powered RX-8. It's the same story inside, where the hybrid and the EV are all but identical. Significantly, the hybrid MX-30 is expected to cost less than the electric model, which carries a base price of ˆ33,490 (about $40,000) in Germany. All told, it's better positioned than the EV to stick the landing if it's sent to the United States. Mazda hasn't yet published a list of the countries where it will sell the hybrid MX-30. Autoblog asked the company for additional details, and received word back that the company hasn't yet "made any announcements on MX-30 for the U.S. market."
