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.

These are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.

Mansory G63 AMG Sahara Edition substitutes performance for taste

We aren't sure if it's an unwritten rule or not, but it seems like European tuners are wholly incapable of building cars whose aesthetics don't offend people blessed with the gift of sight. Take Mansory, for example. The Swiss tuner has turned its hand to the Mercedes-Benz G-Class, a vehicle that on it's own is not exactly a visual stunner. Functional sure, but not exactly beautiful. But with Mansory wielding the design pen, the result is, well, yeah. It's not great. This is the Mansory G63 AMG Sahara Edition, and surprisingly, its camouflaged paint scheme is one of its least obnoxious qualities. But its grille, headlights, hood scoop, roof-mounted lights and rear spoiler just don't do this Mercedes any favors. And for some reason, the tuning firm has decided to put two different styles of 22-inch alloys. The driver's side isn't horrible, although we can't say the same about passenger-side hoops. The interior treatment is nothing compared to the cabin, though. Falcons. There are falcons in the headrests. No, we don't know why either. The avian theme isn't limited to the headrests, though, as Mansory has added wings to the seats, dash and door panels, all the while continuing on with camouflage color scheme on certain interior surfaces. Of course, if you can live with the design decisions, you'll be getting a ludicrously potent G-Wagen. Mansory has boosted the 5.5-liter, biturbocharged V8 to 828 horsepower while it's actually been limited to 737 pound-feet of torque. We aren't sure what the addition of 292 hp and 177 lb-ft of torque does to the G63's run to 60, although we're betting the Mansory version is a lot quick than the 5.3-second stock time.
