Emerging Chinese EV maker NIO announced Friday it has officially begun deliveries of its EC7 electric coupe SUV, deemed one of the most aerodynamic SUVs on the market. NIO’s new flagship coupe is poised to compete in an expanding premium electric SUV market along with the Polestar 3.

NIO unveiled its latest electric model, the EC7, during NIO Day 2022 this past December. With a drag coefficient as low as 0.23 Cd, NIO claims its flagship SUV features market-leading aerodynamics and efficiency.

In comparison, the Tesla Model X is considered one of the most aerodynamic SUVs in the world at 0.25 Cd. The Polestar 3, slated to begin deliveries later this year, has a drag coefficient of 0.29 Cd.

The NIO EC7 is a mid-large size coupe SUV equipped with NIO’s second-gen NT 2.0 tech platform, Smart Matrix LED headlights with LiDAR, and an active spoiler that can reduce drag by 4% in Eco mode.

On the inside, the EC7 includes a panoramic sunroof with smart electrochromic glass, sports seats with zero-gravity mode, enabling you to relax with your feet up, and a second-gen digital cockpit.

Powered by a dual-motor AWD system and SiC power module, NIO’s SUV delivers up to 480 kW (643 hp) and 626 lb-ft (850 Nm) torque enabling a 0 to 62 mph (0 to 100 km/h) in 3.8 seconds.

The EC7 has three battery options, 75 kWh, 100 kWh, or 150 kWh, delivering ranges up to 304 miles (490 km), 395 miles (636 km), and 584 miles (940 km), respectively. Keep in mind, however, that these are CLTC numbers; EPA standard figures are generally about 25% lower.

According to NIO, prices for the EC7 will range from 488,000 RMB ($70,599) to 578,000 RMB ($83,620), with European prices coming at a later date.

How does NIO’s flagship SUV compare to the Polestar 3

The newly released NIO EC7 will compete in China’s quickly expanding electric luxury SUV segment. Another emerging EV maker, Polestar, is set to release its first electric SUV, the Polestar 3, later this year as one of the most highly anticipated EV launches of the year.

Polestar unveiled its “SUV for the electric age” in October as part of the EV maker’s new wave of models after finding success with the Polestar 2.

On the inside, the Polestar 3 also incorporates Scandinavian minimalism with a panoramic sunroof (with high-tech glass) and built-in Android Automotive OS.

The SUV is powered by two electric motors with computer-assisted power distribution to deliver up to 517 hp and 671 lb-ft of torque while enabling 0 to 60 mph capabilities in 4.6 seconds.

With a 111 kWh battery, the Polestar 3 can achieve up to 300 miles of range, while the added performance pack will lower it to 270 miles. These are preliminary figures, but they are based on EPA standards.

The Polestar 3 features the automaker’s elegant Swedish minimalist exterior design, enhanced aerodynamics, and innovative safety features like the font grille’s “Smartzone,” which essentially acts as a third eye with radars, cameras, and other sensors.

Polestar unveiled its electric SUV in China last month with a starting price of 698,000 RMB (roughly 101,000) for the long-range model and 798,000 RMB ($115,000) for the high-performance SUV. According to Polestar’s website, the Polestar 3 will launch in the third quarter of 2023.

This electric excavator has battery swap tech that lets it recharge in minutes [update]

The electric construction equipment experts at XCMG just released a new, 25 ton electric crawler excavator ahead of bauma 2025 – and they have their eye on the global urban construction, mine operations, and logistical material handling markets.

UPDATE: telematics announcement.

Powered by a high-capacity 400 kWh lithium iron phosphate battery capable of delivering up to 8 hours of continuous operation, the XE215EV electric excavator promises uninterrupted operation at a lower cost of ownership and with even less downtime than its diesel counterparts.

XCMG is delivering on part of that reduced downtime promise with the lower maintenance and easier repair needs of electric equipment, and delivering on the rest of it with lickety-quick DC fast charging that can recharge the machine’s massive battery in 1.5-2 hours … but that’s not the slick bit. The XCMG XE125EV can be powered up without leaving the job site thanks to its BYD battery swap technology.

We first covered XCMG and its battery swap technology back in January, and covered similar battery-swap tech being developed by MOOG Construction offshoot ZQUIP, as well – but while XCMG’s battery tech has been in production for several years, it’s still not widely known about in the West (even within the industry).

XCMG showed off its latest electric equipment at the December 2024 bauma China, including an updated version of its of its 85-ton autonomous electric mining truck that features a fully cab-less design – meaning there isn’t even a place for an operator to sit, let alone operate. And that’s too bad, because what operator wouldn’t want to experience an electric truck putting down 1070 hp more than 16,000 lb-ft of torque!?

Easy in, easy out

The best part? All of the company’s heavy equipment assets – from excavators to terminal tractors to dump trucks and wheel loaders – all use the same 400 kWh BYD battery packs, Milwaukee tool style. That means an equipment fleet can utilize x number of vehicles with a fraction of the total battery capacity and material needs of other asset brands. That’s not just a smart use of limited materials, it’s a smarter use of energy.

You can check out all the XE215EV’s specs at this tear sheet, and get an in-person look at the Chinese company’s latest electric excavator this week in Munich, Germany.

Telematics announcement at bauma

Earlier today, XCMG launched its next-generation Xrea Global Telematics Platform, integrating IoT, big data, cloud computing, and AI to enable what it’s caling, “seamless cross-border fleet management.”

The new telematics platform supports a dozen languages via PC and mobile interfaces, and offers real-time diagnostics, predictive maintenance, and data-driven optimization of both the vehicle and the vehicle’s batteries, empowering equipment managers and fleet operators to track fleets across town, or across time zones.

“XCMG remains committed to advancing engineering technology to empower a sustainable future. Our mission is to deliver efficient, intelligent, and eco-friendly lifecycle solutions for global clients,” said Mr. Yang Dongsheng, Chairman of XCMG Group and XCMG Machinery. “Today, 19% of our product portfolio comprises green innovations under our ‘Green Mountain’ new energy line, with full electrification across all series underway.”

Tesla (TSLA) is having a terrible month, and it's only April 10th!

On today’s troubling episode of Quick Charge, we explore all the troubles befalling Tesla (and TSLA stock) in the month April – with top executives fleeing the ship, demand plummeting, sales slipping, government incentives at home and abroad under threat, and a raft of receipts brought on by an OpenAI lawsuit hitting the brand, it’s already a bad month for Elon … and there’s still 20 more days to go!

None of this even touches on the $43 million “backlogged” rebate scandal Tesla’s facing in Canada that’s being blamed for people’s negative attitudes about the brand (ha!) or the fact that neither the long-promised Roadster 2.0 or the Tesla Semi will see production anytime this year, either.

The word you’re looking for when you think of Tesla these days is, “cooked.”

A vast 600 MW Texas solar farm just hit a major milestone [update]

Renewable developer Vesper Energy has cut the ribbon on Hornet Solar in Swisher County, Texas, one of the largest single-phase solar farms in the US.

As Electrek reported in January, the 600-megawatt (MW) Hornet Solar includes over 1.36 million modules covering more than 6 square miles. The project will contribute more than $100 million in new tax revenue to Swisher County and deliver 600 MWac of energy–enough to power 160,000 homes annually. 


January 30, 2025: “The seamless coordination between our team and our EPC partner, Blattner, has enabled us to remain ahead of schedule and on budget while ensuring quality throughout the process,” said Juan Suarez, co-CEO of Irving-based Vesper Energy.

Hornet Solar uses bifacial solar panels mounted on a single-axis tracking system to maximize efficiency. The solar farm is connected to Oncor Electric’s transmission system within ERCOT and is contracted to provide power to four off-take partners through individual Virtual Power Purchase Agreements (VPPAs).

The Hornet Solar project in the Texas Panhandle is on track to be fully online by spring 2025.

Texas is a utility-scale solar leader in the US, with a ranking of No. 2 and 37,713 MW currently installed. It’s projected to install 51,144 MW over the next five years and move into the No. 1 spot, according to the Solar Energy Industries Association (SEIA). The total solar investment in the state is $45.2 billion.

On January 21, the SEIA, Conservative Texans for Energy Innovation (CTEI), Advanced Power Alliance (APA), and the Texas Solar + Storage Association (TSSA) reported that existing and expected utility-scale solar, wind, and battery storage projects will contribute over $20 billion in total tax revenue – and pay Texas landowners $29.5 billion – over the projects’ lifetimes.
