Volvo has been suspicious of Volkswagen's TDI diesel engine for years

Many consumers were surprised to find out that Volkswagen fitted its diesel-powered cars with an illegal defeat device designed specifically to cheat on emissions tests. However, reports now indicate that in the auto industry, the device was considered an open secret.

Kent Falck, a vehicle line executive at Volvo, explains his team became suspicious of Volkswagen’s TDI turbodiesel engine about seven years ago. The Swedish carmaker wanted to sell diesel-powered cars in the United States, but it never managed to match Volkswagen’s TDI mill in terms of emissions, performance, and fuel economy, even though both companies used similar software.

“We sat in a room and reviewed all the facts, figures, whatever we have, with the specialists. (But) we can’t manage it, how are the others doing it? We don’t know,” Falck remembered.

While Volvo initially believed that Volkswagen had developed an advanced new technology that it wanted to keep secret, executives ultimately concluded that meeting U.S. emissions regulations without resorting to costly solutions — such as after-treatment systems — was impossible. Falck told Australian news site News.com.au that he started raising questions about Volkswagen’s TDI engine seven years ago.

“We have the same suppliers, we have Bosch, we have Denso, we are working with the same partners, so we know this technology doesn’t exist,” he said.

Volvo couldn’t prove that Volkswagen was using an illegal defeat device, and it never went public with its suspicions. The company gave up on trying to sell diesels on our shores, and it focused on developing gasoline-electric plug-in hybrid drivetrains instead. Falck pointed out that many other automakers who wanted a slice of the diesel market in the U.S. threw in the towel for the same reason.

Other companies were suspicious as well. Notably, former General Motors vice chairman Bob Lutz recently revealed that the engineers he was in charge of took apart diesel-powered Volkswagens and couldn’t figure out how they complied with emissions regulations, especially in states with strict norms such as California. Now we know.

A new sodium battery posts wild four-minute charging numbers, but don’t expect it in an EV yet
The breakthrough could improve fast charging and battery life, but the study hasn’t demonstrated those results in a production-sized pack
EV Charger

A new sodium-metal battery has posted a charging number that makes today’s EVs look painfully slow. In laboratory testing, the cell operated at a 15C rate, equivalent to completing a charge or discharge in roughly four minutes.

That doesn’t mean researchers plugged in an electric car and watched it fill up before the driver finished buying coffee. The result came from a small experimental cell using a new quasi-solid electrolyte, while the larger pouch-cell prototype delivered far less dramatic performance.

The Apple Car may be dead, but it became the foundation of Apple Intelligence
A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.
Apple Intelligence in Apple Car

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

Volkswagen’s ID. Unyx 09 just leaked, and it’s the kind of EV I want to see in the US
VW's partnership with Xpeng is producing exactly what we hoped.
Bumper, Transportation, Vehicle

I've been watching Volkswagen's China lineup quietly get cooler for the past two years, but the ID. Unyx 09 might be the moment it finally gets exciting, not just for Chinese buyers, but for the rest of the world as well. 

Regulatory filings from China's Ministry of Industry and Information Technology, Batch 409, have exposed the full specs of the upcoming sedan ahead of its official launch later this year, and it looks nothing like any VW car I've seen before (via CarNewsChina).
