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.

Sales start for $146,000 Mercedes-Benz S500 Plug In Hybrid

Mercedes-Benz's first production plug-in hybrid is chock full of astounding numbers, including the price tag. The base price is 108,944.50 euros, or about $146,000 US. If that didn't make your eyes glaze over, the Daimler division is ready to take your down payments now that the Mercedes-Benz S500 Plug-in Hybrid is officially on sale. Deliveries to European dealerships start in September. Details on the PHEV sedan were divulged last August and it was first shown off at last year's Frankfurt Motor Show. Benz calls it the, "first luxury saloon with the performance of a V8 and the fuel consumption of a compact model." That's no exaggeration. The car's powertrain that pairs a 3.0-liter V6 twin-turbo with an electric motor that delivers 436 horsepower and a 0-62 mile per hour acceleration time of just 5.2 seconds. Top speed is 155 miles an hour. On the green side, the car can go as far as almost 21 miles on electric power alone and gets a fuel-efficiency rating, on the more lenient European driving cycle, of 84 miles per gallon equivalent. The car also includes a so-called COMAND navigation system that tweaks how the electric motor is used based on the driver's desired route. Very high-tech.

"The S 500 PLUG-IN HYBRID is the first luxury saloon with the performance of a V8 and the fuel consumption of a compact model.

Smart brand might be doomed

Reports are painting a less than rosy picture of the Smart brand's future. The Daimler-owned carmaker is going fully electric in 2020, but that might not be enough to keep it alive for long. Inside sources, quoted by Automobile Magazine, are saying Renault is likely to pull out of the partnership that created the current Smart ForTwo/Renault Twingo pairing introduced in 2014. The two rear-engined cars share a platform, and when the current Twingo is done for, Renault might want to part ways. In addition, Mercedes isn't willing to prop up Smart on its own, and there is a possibility that the entire Smart brand could be shuttered by 2026. A previous joint venture was the ForFour hatch co-developed with Mitsubishi, and despite the ForFour name living on in the current generation rear-engined car, the earlier FWD hatchback has quickly been forgotten. Not long ago, Smart presented its Forease open-top concept to give customers a glimpse of what future Smart cars would look like, but at its heart the Forease was still a current Smart dressed up with concept car details. The next-generation Mercedes-Benz A-Class is to be signed off in 2021 for a 2025 introduction, and it can be underpinned by a more flexible, fully scalable platform that could also serve to support a new entry-level Mercedes-Benz vehicle that could render the separate Smart brand pointless. Then there's Geely, who now owns nearly 10 percent of Daimler, and who is partnering with Daimler to launch a new "premium" ride-hailing venture in China. As Geely develops its mobility solutions, it is likely to keep an eye on Smart: Smart cars have been car-sharing staples around the world for quite a while, from users such as Car2Go. Automobile Magazine says that if a Smart is co-developed with Geely, it might suit the Chinese market well, but a global business case might be challenging. In any case, if Smart wants to survive beyond the current Renault partnership, the new model should be agreed upon quickly, and it must be based on a platform flexible enough to support full electric drive. Reportedly, there are now ongoing feasibility studies for a fully electric Daimler "U-Class," which would include a Smart-like three or five-door hatch with two wheelbase options, a ride-sharing shuttle with autonomous capabilities, and an urban delivery panel van. But Smart must justify itself for the upcoming decades, or the future Daimler products that occupy its niche will be wearing a three-pointed star instead.
