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.

This is the 2017 Mazda MX-5 RF targa-roof fastback

We knew Mazda was going to introduce a new Miata variant ahead of the 2016 New York International Auto Show, but the smart money was on a power retractable hardtop version that largely mirrored the last-gen car's folding number. So it was a surprise when the new 2017 Mazda MX-5 RF – retractable fastback – drove onto the stage sporting wild buttresses and a hide-away targa roof panel. The buttresses lift up and swallow the rear window and roof panel in a matter of seconds, and then the buttresses snug back down. This leaves a hoop spanning the buttresses, but at least it's done up in black to be less visually apparent. The result is more of a targa roof experience, rather than the previous PRHT which gave occupants essentially the same experience as the soft-top with the top down. No matter. The result is stunning, and will differentiate the RF even more from the standard MX-5. Mazda designers took extra care to make sure the interface between the MX-5's dramatic fenders and the trailing edges of the roof support provided enough visual drama. Mission accomplished, we'd say. We can't take our eyes off that part of the car. View 13 Photos As you might expect, mechanical changes seem to be minor, although we'll be asking for detailed specs. Both the 1.5- and 2.0-liter engines will be available globally, but only the 2.0-liter Skyactiv-G engine will be sold in the US. The roof can be operated at up to 6.2 mph. Mazda claims the truck space is unaltered from the soft-top model. We don't yet know how much, if any, the RF's mechanism adds to the bantamweight roadster, nor the premium it'll command. Expect those details closer to launch. Related Video:

2019 Mazda3 fuel economy announced for AWD, hatchback models

Although Mazda engineers gave us fuel economy numbers for one configuration of 2019 Mazda3 at the car's Los Angeles debut, there were still a few versions left out. Now Mazda has released the data for every body style, drivetrain and transmission configuration. That includes the all-new all-wheel-drive iteration, which we will have a full review of this week. Discerning these numbers is a tad tricky since there are three powertrain combinations for each 2019 Mazda3 bodystyle, and they all get slightly different fuel economy. We've listed the different combinations in a chart below: There are a few key takeaways, the first being that the sedan is always the most efficient version of the Mazda3, likely because of better aerodynamics compared to the hatchback. Second, all-wheel drive will cost you fuel economy due to the extra weight of the axles and differential, and the added drag on the engine. Third, the most efficient versions of each body have the same fuel economy numbers as the outgoing Mazda3. The manual transmission-equipped Mazda3 has actually improved fuel economy over the old version by 2 mpg on the highway, and 1 in combined driving. Also worth noting is that only one trim level of the sedan is available with cylinder deactivation and front-wheel drive, and that's the top-level Premium trim. Opting for all-wheel drive on any trim or body style will come with an engine with cylinder deactivation. The hatchback is also the only Mazda3 available with a manual transmission, and it's only offered on the front-drive version.
