Evidence That Mazda's Next MX-5 Miata Will Switch To Electric

The rumors flying around concerning which way the next-generation Mazda MX-5 Miata's powertrain will go appear to have reached a climax. And according to Britain's Auto Express magazine, the answer seems to be — fully electric, or at least an EV powertrain will be optional as will an all-new ICE unit.
The current model 'ND' version of the MX-5 has been on the market for more than ten years now and has practically become the antithesis of increasingly heavy electric sports cars like the MG Cyberster, Lotus Evija and Maserati GranTurismo Folgore. Hovering at around 2200 lbs since its inception way back in 1989, the tiny Mazda has stayed true to its original philosophy — lightweight sports.
Auto Express reports that it has uncovered patents, filed in the U.S. of the MX-5 Miata with electric power. These patents reveal batteries located in the transmissions tunnel in a coupe that can only be interpreted as the next-gen MX-5. The construction in the patent images goes against the typical pure EV 'skateboard' architecture which could make it difficult to reproduce the low-to-the-ground driving position we see in all previous roadsters.
Battery placement in the transmission tunnel is not new, with the most recent Lamborghini Revuelto's employing a 3.8kWh pack in its tunnel. While Mazda's new setup is pure electric, the Lamborghini uses its battery to complement a plug-in hybrid system.

The MX-5's conventional size, form, and weight distribution have been maintained by using this somewhat creative approach to battery integration. In addition to the transmission tunnel, Mazda has incorporated batteries behind both seats, similar to the layout in the upcoming Porsche Cayman EV.
Although it isn't stated in the patents, the necessity of a "transmission tunnel" in the first place clearly implies that the technology is built on a shared architecture between an internal combustion engined car with a conventional gearbox and a pure-EV. Mazda realizes that going full electric with its flagship sports car is too extreme and financially risky, so it's hedging its bets and will offer an EV and an ICE version.
According to Mazda's application, "the yaw moment of inertia can be further reduced because the battery is installed in the tunnel portion, allowing the vehicle's center of gravity to be near the middle of the vehicle.'
Mazda's well-known "Jinba-ittai" (horse and rider as one) philosophy has made the MX-5 seem more agile since its inception. The "yaw of inertia" that Mazda is referring to here is basically the vehicle's directional change, so decreasing this helps make a car handle better.
While the British magazine mentions that Mazda has not leaked any information on the potential battery size yet, we can be reasonably sure that it will get a unit larger than the 35.5kWh battery in the MX-30 SUV, which was prematurely canceled after its poor 100-mile range forced its exit from the U.S. lineup.
Given that the MX-5 has always been rear-wheel-drive, and given that the patent image shows a single electric motor behind the seats, we can expect the new 'NE' model to carry on the rear-drive tradition.
What will the new MX-5 look like? The company revealed the drop-dead good-looking, rotary-powered Iconic SP concept at the 2023 Tokyo Motor Show (now called the less impactful 'Japan Mobility Show'!) which the magazine suggests will influence the next MX-5's styling.
However, the patent application, which is merely named "electric automobile," does not confirm that the MX-5 would be electric-only. Earlier this year, Mazda unveiled its "multi-solution strategy" to provide customers with multiple powertrain sources, including battery electric vehicles, hybrids, and internal combustion engines.
As a result, we expect Mazda's new internal-combustion Skyactiv-Z engine to power the "NE" model, which will replace the current "ND" generation MX-5 later this decade. According to the company, the new powertrain will meet Euro 7 emissions regulations and serve as the foundation of Mazda's lineup "for small products in the electrification era.'
So expect the next MX-5 to offer two very different MX-5 Miata models by 2027, one delivering electric-only power and the other fitted with a conventional gasoline engine.

Aircraft delivery delays are stunting growth, but there's a silver lining
NEW DELHI, India -- The backlog for commercial airline orders is currently more than 17,000 planes, according to IATA, as aircraft makers continue to fall short of production targets. It's a backlog of 14 years at current production rates. The backlog is constraining industry growth and increasing the age of fleets, officials said during IATA's Annual General Meeting here. The industry's average aircraft age has increased from 13 years in 2015 to 15 years currently. This year, Boeing and Airbus had forecast 1,430 deliveries, according to airline industry data company Cirium, but through the first four months of the year they had delivered just 359 planes. "It's very unpredictable. You order an aircraft today, your guess is as good as mine when you're going to receive it," said Nick Careen, IATA's senior vice president of operations, safety and security. The industry's annual fleet replacement rate is just half of the 5% to 6% that it was in 2020, IATA director general Willie Walsh said. Walsh criticized manufacturers for not making faster progress on supply chain problems that he said could last until the end of the decade. A variety of issues have contributed to supply challenges, including a shortage of skilled labor and titanium sourcing problems, Careen added. A shortage of spare parts and aircraft grounded for inspections of Pratt & Whitney GTF engines have exacerbated the shortfall. IndiGo CEO Peter Elbers, whose airline currently has a narrowbody order book of nearly 1,000 Airbus planes plus 60 widebody orders, said delivery delays and shortfalls are hurting the airline industry. "I would say it's a missed opportunity in terms of addressing the market demand," he said. But not everybody agrees. Steve Saxon, a partner and aviation industry analyst for the consulting firm McKinsey, said delivery delays have been a blessing for airlines, driving up yields and profitability by preventing them from growing too fast. Last year, the airline industry recorded a net profit of $32.4 billion, according to IATA. Walsh, too, acknowledged that the slow delivery pipeline has a silver lining. Last year, airlines filled 84% of their seats, a record. "I didn't think I'd ever see load factors at that level," he said.

The Polestar 4 now comes from South Korea instead of China
The 2026 Polestar 4 — the one without a rearview window — is now on sale in the US. And instead of being manufactured in China like the 2025 version, this all-electric coupe will be imported from South Korea. Of course, Polestar is a Volvo offshoot based in Sweden, and like Volvo it's owned by China's Geely. But with trade tension between the US and China escalating, Polestar's owners made a deal with Renault Korea Motors to manufacture the Polestar 4 at that company's plant in Busan. The EVs assembled there will be distributed to North America, as well as the South Korean market. That's the big news about the Polestar 4. The EV otherwise remains the same: the long-range single-motor rear-wheel drive version starts at $57,800 (including a $1,400 destination charge), which is only slightly more than the 2025 model year. Meanwhile, a dual-motor Polestar 4 with standard Pilot pack will start at $64,300. The EVs assembled there will be distributed to North America, as well as the South Korean market. The Polestar 4 is a coupe-style SUV with a targeted range over 300 miles and a 102kWh battery. One of the most distinctive features is the total absence of a rear window, which Polestar argues 'enables a new kind of immersive rear occupant experience.' The Verge contributor Daniel Golson said it was a little dark for rear-seat passengers but overall found a lot to like about the digital rearview mirror. The company says it will be its fastest production car to date, with a zero to 60mph sprint time of 3.7 seconds for the dual-motor versions and a maximum power output of 400kW or 544 horsepower. Both dual- and single-motor versions will be available, with single-motor versions featuring rear-wheel drive. The 102kWh battery is fitted to both long-range versions. A disconnect clutch allows the car to disengage the front electric motor when not needed to maximize range and efficiency. The Polestar 4, which is confusingly slotted between the Polestar 2 fastback sedan and the Polestar 3 SUV, is extremely important for the automaker's future. Polestar briefly removed the Polestar 2 from its website amid confusion around new tariffs from the Trump administration. The company is now only offering pre-owned versions of the EV. As InsideEVs notes, that makes the Polestar 4 the cheapest model in Polestar's limited North American lineup.
