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.

Cars with the worst resale value in 2022

Car values are all over the map right now. Used vehicles that were worth a small fortune earlier this year are now coming back to Earth, but the new vehicle supply remains tight. Prices are still elevated overall, but some models have seen more severe price drops. Depreciation strikes almost every model, supply constraint or not, though a few vehicles are leading the way. New research from analytics iSeeCars found that a handful of cars depreciated more than 50 percent over five years, with the BMW 7 Series dropping 56.9 percent and an average price cut of $61,923 over that time. The vehicles with the highest depreciation — or worst resale value — over five years: BMW 7 Series: -56.9% Maserati Ghibli: -56.3% Jaguar XF: -54% Infiniti QX80: -52.6% Cadillac Escalade ESV: 52.3% Mercedes-Benz S-Class: 51.9% Lincoln Navigator: -51.9% Audi A6: -51.5% Volvo S90: -51.4% Ford Expedition: -50.7% iSeeCarsÂ’ research showed that midsize trucks, sports cars, and fuel-efficient vehicles were slowest to depreciate over five years, while itÂ’s clear that luxury brands tend to lose value much faster. As iSeeCarsÂ’ Executive Analyst Karl Brauer explained, used buyers donÂ’t value high-end vehiclesÂ’ features as much as the first owners, so resale values tend to be softer. The tech and options that made the cars so expensive and appealing new donÂ’t add the same value on the used market.

The Nissan Leaf depreciated most among EVs, dropping by 49.1 percent. The average EV depreciation is 44.2 percent, with the Tesla Model S and Model X sliding in right under the bar at 43.7 and 38.8 percent, respectively. As iSeeCars notes, itÂ’s important to be vigilant when car shopping and not let your emotions win over reason. Shiny new luxury cars look great in the showroom, but you could end up taking a bath when you try selling them a few years later on.
