Some intriguing showstoppers from Auto China 2024

“Electric” may be the most appropriate word to describe the atmosphere at the recent Beijing motor show, now considered to be one of the worldÂ’s largest automobile exhibitions. ChinaÂ’s vision of the electric mobility future is on full display during the ten-day event, which ends this weekend. Organizers estimated that 117 new global and China-domestic models would debut in Beijing. In fact, about 30 foreign brands had stands, a turnout that hasnÂ’t been seen at auto shows since before the pandemic. The South Koreans and the Japanese came, and from Germany, representatives making the case for their brands included CEO Oliver Blume of Volkswagen Group, Oliver Zipse of BMW Group and Ola Kallenius of Mercedes-Benz Group. A few of the models would be powered by gasoline—by ICE, or internal combustion engines—but the vibe was clear: electrics are it. According to to show officials, Beijing hosted a total of 278 electric and plug-in hybrid models on display. After digesting most of the reveals unveiled during the show, weÂ’ve parsed a list to a select few of the more interesting models. Here it is, in no particular order: BYD Ocean-M concept BYD has launched off-roaders, SUVs and sedans in its global assault on the car market — and added a hot hatch concept at Auto China. The Ocean-M (above) is a Volkswagen Golf-sized five-door hatchback, meaning itÂ’s likely that BYD will pitch it as a rival for the Volkswagen ID.3 GTX. The show car has sporty design, rises sharply towards the rear window, and sharp surfacing at the front and along the flanks. The show car has a huge rear wing, aero diffuser and side blades.   Denza Z9GT BYDÂ’s luxury brand, Denza, a joint venture between BYD and Mercedes-Benz, showed the Z9 GT, a massive wagon carrying three electric motors putting out a stunning 952 horsepower. The EV weighs an extraordinary 6,338 pounds, almost 440 pounds more than a Rolls-Royce Cullinan. BYD's design boss is a German -- Wolfgang Egger, who previously worked for Alfa Romeo and Audi. Lamborghini Urus SE The Volkswagen subsidiary brought a bit of Italian sex appeal to Beijing in the form of “super” luxury SUV that received its first public premiere in China. The plug-in hybrid Uris SE SUV gets nearly 800 horsepower as well as a series of visual and technology updates inside and out.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
