NIO day 2023

We currently sit three weeks away from NIO Day 2023, the annual event held by one of China’s leading EV automakers that caps off the year with new and exciting technologies to come. We know NIO intends to unveil a new flagship model during the event and it’s rumored to be the automaker’s top-of-the-line sedan, possibly named the ET9. Here’s what we know.

NIO Day is an event we look forward to toward the end of each year, as it never fails to showcase new EV models and adjacent technologies. Due to the Pandemic, NIO Day 2020 was actually held in January of 2021, when the automaker unveiled its flagship sedan, the ET7.

NIO Day 2021 came as scheduled later that year and included the debut of the ET5 sedan, as well as plans to expand to new markets around the globe by 2025, including the US. Those plans for North America have wavered a bit recently, but NIO Day continues to deliver.

2022’s event included unveilings of NIO’s ES8 and EC7 SUVs, pushing the automaker’s lineup to eight available EVs. Later this month at NIO Day 2023, we know that EV family will grow by at least one – but what model we see unveiled remains somewhat of a mystery.

NIO Day 2023 takes place December 23

According to an announcement from cofounder and CEO William Li on its mobile app this week, NIO Day 2023 will take place on December 23 at the Xi’an Olympic Sports Center located in the Shaanxi Province of northwest China.

Li also revealed that NIO intends to unveil a new flagship EV model during the event, sparking a blaze of speculation about what the public can expect. NIO’s model nomenclature consists of a letter and a number – the higher the number, the more premium the EV.

The company’s current lineup consists of five SUVs and three sedans, the most premium being the aforementioned ES8 SUV. However, there have been rumors swirling for over a year that NIO has been developing an ultra-luxury sedan to compete with the likes of the Mercedes-Maybach S-Class.

Per a report from CnEVPost, Edison Yu’s team of analysts at Deutsche Bank believe that luxe sedan is in fact on the agenda for NIO Day 2023, and it will be called the ET9. Per a research from Edison Yu sent to investors:

Then at the end of Dec, the company will unveil its new flagship vehicle at NIO Day featuring the latest technologies. Our guess is this could be an ultra high-end sedan ‘ET9’ that would be comparable with Maybach.

The team also said the new top-tier sedan will be produced in low volume and exist as a halo EV to add to the prowess of the growing brand. When speaking to this NIO Day 2023 debut, whatever model it may end up being, William Li relayed the EV will feature the company’s latest tech and will “become the global technology benchmark for smart EVs.”

There’s a genuine chance Deutsche Bank is incorrect and NIO’s next sedan is called the ET8 to match its SUV counterpart, but we’d expect the model to be called either the 8 or the 9. Either way, it is reportedly expected to cost over CNY 1 million ($141,500).

Regardless of the name, we are sure to see a new EV model come out of NIO Day 2023. We will be tuning and will be sure to report back as we learn more. Check back soon.

This startup wants the $80-billion U.S. railroad industry to switch from diesel to batteries

This startup wants the -billion U.S. railroad industry to switch from diesel to batteries

Voltify plans to build a series of energy microgrids to power its locomotive batteries, as shown in this computer-generated image.

Voltify

Daphna Langer has a bold ambition: To decarbonize the rail industry in less than a decade.

How? By convincing U.S. freight railroad companies to switch from diesel power to rechargeable batteries — part of a business model Langer estimates could make her company, Voltify, as much as $10 billion a year.

The rail industry needs to reduce its emissions by 5% a year by 2030 to reach net-zero goals, according to a 2023 report by the International Energy Agency. In addition, switching to battery electricity would save U.S. rail freight companies $94 billion over 20 years, according to a 2021 study published in the journal Nature Energy.

Voltify’s VoltCars — essentially sodium-ion batteries on wheels — are designed to connect to existing freight locomotives.

Convincing the $80-billion U.S. rail industry to switch from a traditional and long-relied on fossil fuel to renewable energy might seem a tough task, but there are several reasons Langer said she is confident in Voltify’s goal.

After a stint advising multiple early-stage companies in the climate industry, Langer noticed two things that limited their growth. “Most of them rely on subsidies of governments, and [the] second [factor] is that they rely on manufacturing and scaling that just doesn’t exist today,” she said.

In a bid to overcome those hurdles, Langer held meetings with hundreds of people in the energy and materials industries, seeking opportunities. When she first met her co-founder Alon Kessel, it was a “ding ding” moment, she said.

Kessel knew the renewable energy market well, having co-founded Doral, a firm that owns and operates dozens of solar energy farms in the U.S. and Europe. He calculated that the six largest freight railroad companies in the U.S. — including Union Pacific and CSX — were collectively spending more than $11 billion a year on diesel, a figure verified by CNBC. Union Pacific, for example, spent almost $2.5 billion on fuel in 2024, per its annual report.

Langer and Kessel saw an opportunity. What if they could convince the large companies — known as Class 1 railroads — to convert their locomotives from diesel to battery power?

“Converting six companies is not that hard. And having that ability to create such an impact with just six companies, it’s huge,” Langer said. There is almost 140,000 miles of freight railroad track in the U.S., with the majority of the locomotives powered by diesel as there is little overhead electrification.

Langer and Kessel founded Voltify in 2023 and set about meeting the railroad companies. But they found initial resistance. “There’s a lot of skepticism, because this is such a traditional industry, and uptime and and reliability are key,” Langer said. “We’ve been figuring out what would be able to … fit into their schedule, to fit into their operations without harming their efficiency.”

The companies’ biggest concern was the amount of time it might take to charge the batteries, and that there would always be the power supply to do so. “The rail companies, who have been very blunt about it, [said] ‘Listen, we don’t really care about the energy source. We just need to make sure that it’s always up. There’s always energy,'” Langer said.

So Voltify spent about a year working on an algorithm that could forecast the energy demands of trains “in every route,” Langer said, and the company is also building its first solar-powered energy microgrid that Langer said is on track to be finished by the end of the year. “Our calculations show that a network of these microgrids could eventually power all trains in North America,” Langer told CNBC in an email. Voltify estimates that to do so would require 1,400 microgrids.

Wabtec’s FLXdrive battery locomotive was developed in 2019.

Voltify is in “very active” talks with three of North America’s largest railroad companies, Langer said, adding that it is set to run a demonstration project with a smaller railroad company later this year. Voltify is also starting a pilot with a Class 1 railroad company in early 2026, and Langer said it is “expected” that this will become a commercial deployment after several months.

Voltify isn’t the first company to come up with the idea of powering freight trains with batteries. In 2019, freight rail firm Wabtec developed a battery-electric locomotive called the FLXdrive, with the first trains set to operate in Australia after being ordered by miner BHP Group. The company also tested its battery-electric locomotive with GE, and said in an email to CNBC that it plans to test and operate FLXdrive trains in North and South American markets.

The technology can reduce diesel consumption and emissions by 30%, according to Tim Bader, Wabtec’s director of external and engineering communications, in an email to CNBC. “This benefit is critical since fuel is one of the major operating costs for a railroad,” he said.

But as the technology is emerging, there are challenges such as charging time and battery capacity, plus a “challenging” business case given the infrastructure investments required. “Like any emerging technology, these challenges will diminish as the industry continues to research and improve battery-power solutions,” Bader said.

There’s also “substantial” market potential for battery-powered passenger trains, according to Tobias Bauer, the acting CEO for Siemens Mobility North America, in an email to CNBC. “Battery-powered trains represent a new and exciting platform for the rail market, particularly as operators seek alternatives for non-electrified routes,” Bauer said.

Siemens Mobility has sold more than 400 diesel-electric Charger locomotives in North America, and in June launched its battery-electric train, the Charger B+AC, selling 13 to the New York’s Metropolitan Transportation Authority and Metro-North Railroad.

The new locomotive draws electricity from overhead catenary wires and transfers to battery power when needed, according to an online release. While the locomotives’ range is currently up to 100 miles, Bauer said that is expected to grow as the battery technology advances.

In February, Siemens Mobility received an order from Swiss freight operator WRS Widmer Rail Services for two of its Vectron lithium-ion battery locomotives, which can be used for shunting without the need for overhead power lines. Asked about the potential for battery-powered freight trains, Bauer said: “A full transition to battery-powered freight would depend on route specifics and charging infrastructure, but the potential is there.”

Aventon’s final summer sale gives the new Abound SR smart cargo e-bike its first discount to $1,799, more from $1,199

Aventon has launched its final summer sale through September 3 with up to $500 being taken off its e-bike lineup, including increased savings on legacy models, and two of its newest smart models seeing price cuts. Alongside the second-ever discount on the new Pace 4 Step-Through e-bike, we’re seeing the first cash savings on Aventon’s Abound SR Cargo e-bike to $1,799 shipped. This smart commuting solution has been fetching $1,899 since hitting the market at the end of 2024, with discounts having been placed on its predecessor model (currently down at $1,599). This is the first time we’ve spotted any savings being attached to this model, setting the bar for future discounts. Head below to learn more about it or to check out the full lineup of deals during this sale.

The new Aventon Abound SR e-bike takes all that we love about its predecessor and steps up the game with smarter features. To start, there is a 750W rear hub motor (1,188W peak) paired with a 733Wh battery (which you can conveniently unlock and remove without keys via the LCD screen) that provides you with up to a 60-mile travel range at up to 20 MPH speeds (that can be adjusted to 25 MPH). There are three riding modes available here, with the added Ride Tune customization letting you alter their performances to suit your preferences.
