A deadly Tesla crash in China last November, which at the time was subject to swirling social media rumors that blamed it on Autopilot or brake failure or too-powerful electric motors, turns out to have just been another example of pedal confusion.

But now, data from the car’s Event Data Recorder has been posted to the internet by Xiao Te, a Tesla owner in China. And the data shows that in the seconds before the crash, the accelerator pedal was held at 100%, with no brakes applied. Further, the steering wheel did show inputs during that time frame, Autopilot was not active, and the car’s stability control system was engaged.

While the police investigation is not yet finished, the driver, who survived the crash and was wearing his seatbelt at the time, was not driving under the influence of drugs or alcohol.

The video of the crash received quite a lot of play because of how dramatic it was. In about 30 seconds, a Model Y traveled 2.6 kilometers at up to 164km/h (101mph), weaving through traffic, sideswiping other vehicles until it crashed into a storefront. The whole thing was tracked by Chinese CCTV cameras and stitched together (warning: graphic video).

The driver survived, though at least one bystander was left dead (most sources we’ve seen say two, but some say one). After the crash, the driver was interviewed stating that he had never touched the accelerator, and that he was pressing the brake the whole time.

This led to social media rumors suggesting brake failure, a topic that has made the rounds multiple times on Chinese social media, including when a protester showed up at Tesla’s booth at the Shanghai Auto Show.

Other theories made their way around social media as well. Some thought that it could have been Autopilot gone rogue during an attempt to autopark the car, and some said that even if the brakes are functioning, a Tesla’s motor is too powerful and can overcome the brakes and therefore lead to a dangerous event like this.

But the video showed that the brake lights never turned on, and the vehicle was not behaving in a manner consistent with Autopilot usage either.

So, at the time, we predicted that this was just another example of pedal confusion, which it turns out to have been. Pedal confusion is where a driver presses the accelerator thinking it’s the brake and then, while panicking, continues to press the accelerator harder and harder, only contributing to the problem.

Accusations of brake failure are not just limited to China – Tesla has also received many such complaints in the US, which at one point it responded to in a blog post broadly claiming, “there is no ‘unintended acceleration’ in Tesla vehicles.”

These complaints were examined by the NHTSA, which found that incidents of sudden unintended acceleration in Teslas were a result of driver error, and not due to any design flaw in the vehicle. The NHTSA reminds drivers that there are 16,000 preventable crashes per year in the US due to pedal error and cautions drivers to be aware of this problem, regardless of what make and model of car they drive.

Kia’s EV3 is the best-selling retail EV in the UK right now

Kia's EV3 is the best-selling retail EV in the UK right now

Kia’s electric SUVs are taking over. The EV3 is the best-selling retail EV in the UK this year, giving Kia its strongest sales start since it arrived 34 years ago. And it’s not just in the UK. Kia just had its best first quarter globally since it started selling cars in 1962.

Kia EV3 is the best-selling EV in the UK through March

In March, Kia sold a record nearly 20,000 vehicles in the UK, making it the fourth best-selling brand. It was also the second top-seller of electrified vehicles (EVs, PHEVs, and HEVs), accounting for over 55% of sales.

The EV3 remained the best-selling retail EV in the UK last month. Including the EV6, three-row EV9, and Niro EV, electric vehicles represented 21% of Kia’s UK sales in March.

Kia said the EV3 “started with a bang” in January, darting out as the UK’s most popular EV in retail sales. Through March, Kia’s electric SUV has held on to the crown. With the EV3 rolling out, Kia sold over 7,000 electric cars through March, nearly 50% more than in Q1 2024.

The EV3 was the best-selling retail EV in the UK in the first quarter and the fourth best-selling EV overall, including commercial vehicles.

Starting at £33,005 ($42,500), Kia said it’s the “brand’s most affordable EV yet.” It’s available with two battery packs, 58.3 kWh or 81.48 kWh, good for 430 km (270 miles) and 599 km (375 miles) of WLTP range, respectively.

With new EVs on the way, this could be just the start. Kia is launching several new EVs in the UK this year, including the EV4 sedan (and hatchback) and EV5 SUV. It also confirmed that the first PV5 electric vans will be delivered to customers by the end of the year.

Electrek’s Take

Globally, Kia sold a record 772,351 vehicles in the first quarter, its best since it started selling cars in 1962. With the new EV4, the brand’s first electric sedan and hatchback, launching this year, Kia looks to build on its momentum in 2025.

Kia has also made it very clear that it wants to be a global leader in the electric van market with its new Platform Beyond Vehicle (PBV) business, starting with the PV5 later this year.

Earlier today, we learned Kia’s midsize electric SUV, the EV5, is the fourth best-selling EV in Australia through March, outselling every BYD vehicle (at least for now). The EV5 is rolling out to new markets this year, including Canada, the UK, South Korea, and Mexico. However, it will not arrive in the US.

For those in the US, there are still a few Kia EVs to look forward to. Kia is launching the EV4 globally, including in the US, later this year. Although no date has been set, Kia confirmed the EV3 is also coming. It’s expected to arrive in mid-2026.

University of Michigan cracks rapid EV charging in freezing temps

Charging your EV in freezing weather could soon become dramatically faster, thanks to a big breakthrough from the University of Michigan engineers.

Neil Dasgupta, U-M associate professor of mechanical engineering and materials science and engineering and corresponding author of a study published in Joule, and his team have developed an innovative battery structure and coating that can boost lithium-ion EV battery charging speeds by a whopping 500%, even at frigid temperatures as low as 14F (-10C). “Charging an EV battery takes 30 to 40 minutes even for aggressive fast charging, and that time increases to over an hour in the winter,” Dasgupta explained. “This is the pain point we want to address.”

Freezing weather has traditionally been harsh on EV batteries because it slows down the movement of lithium ions, resulting in slower charging speeds and reduced battery life. Automakers have tried thickening battery electrodes to extend driving range, but this makes some of the lithium hard to access, making charging even slower.

Previously, Dasgupta’s group sped up battery charging using lasers to carve pathways around 40 microns in size into the graphite anode. This allowed lithium ions to reach deeper into the battery more quickly. However, cold-weather performance still lagged because a chemical layer formed on the electrodes, blocking the ions. Dasgupta compares this barrier to “trying to cut cold butter,” making charging inefficient.

To solve this, the team coated the battery with a thin, glassy material made of lithium borate-carbonate—only 20 nanometers thick—which prevented the problematic chemical layer from forming. Combined with the microscopic channels, the results were groundbreaking: the modified batteries retained 97% of their capacity even after 100 fast-charging cycles in freezing temperatures.

“We envision this approach as something that EV battery manufacturers could adopt without major changes to existing factories,” Dasgupta noted. “For the first time, we’ve shown a pathway to simultaneously achieve extreme fast charging at low temperatures, without sacrificing the energy density of the lithium-ion battery.”

This innovation could tackle one of the biggest concerns holding potential EV buyers back.

The new battery tech is moving closer to commercialization, supported by the Michigan Economic Development Corporation’s Michigan Translational Research and Commercialization (MTRAC) Advanced Transportation Innovation Hub. The research devices were built at U-M’s Battery Lab and studied with help from the Michigan Center for Materials Characterization.

U-M Innovation Partnerships assisted the team in applying for patents, and Arbor Battery Innovations has licensed the technology for market deployment. Dasgupta and the University of Michigan hold financial stakes in Arbor Battery Innovations.
