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.

2016 Mercedes-Benz C450 AMG Sport bridges the gap between C300 and C63

Mercedes-Benz is looking to its new C-Class for the second member of its new AMG Sport line, unveiling the C450 AMG 4Matic at today's 2015 Detroit Auto Show. Like the GLE450 AMG Coupe that debuted in early December, this particular C-Class bridges the gap between the standard C300 and the new Mercedes-AMG C63. Considering this, the C450 builds on the standard C400's 3.0-liter, twin-turbocharged V6, rather than getting a bespoke, high-performance engine. Output is up from 329 horsepower to 362 ponies, while torque is turned up from 354 pound-feet to 384 lb-ft. The result of these upgrades is a zippy 0-60-mile-per-hour sprint of 4.9 seconds and an electronically limited top speed of 155 mph. Those figures are identical to the Audi S4, while the BMW 335i xDrive is just a smidge quicker to 60, getting there in 4.8 seconds (the Bimmer is, however, limited to just 130 mph). Shuffling the 3.0-liter's grunt to a 4Matic all-wheel-drive system is the responsibility of Mercedes 7G-Tronic automatic gearbox that, despite not being a member of AMG's Speedshift dual-clutch family, still has its own mind for performance. Along with a quick-shifting, automatic Sport Plus mode, the C450 has a full manual shifting mode that, notably, will not automatically upshift, even when the engine is bouncing off the rev limiter. The C450 AMG hasn't only had its straight-line abilities boosted. Mercedes saw fit to include an AMG adaptive sport suspension with three-stage adjustable dampers, which have been pilfered from the C63 AMG. Paired with the aforementioned all-wheel-drive system, which can send up to two-thirds of its power to the rear axle, it's a fair to say this particular sedan should be one of the brand's more agile and entertaining. Beyond the mechanical bits, Mercedes has beefed up the exterior and interior aesthetics for its second AMG Sport model. The exterior has been touched up with new, staggered 18-inch, five-spoke wheels (or optional 19s), a more aggressive front fascia, a new rear bumper with a matte iridium diffuser, distinctive AMG badges and plenty of chrome and gloss-black elements. The cabin, meanwhile, is home to black MB Tex upholstery with red contrast stitching on the dash and doors, while AMG-specific upholstery lines the sport seats. The flat-bottomed, three-spokes steering wheel, meanwhile, is finished in Nappa leather. We'll have more on the 2016 C450 AMG Sport, including live images, coming soon from the floor of the 2015 Detroit Auto Show.

Audi, BMW, Daimler buy Nokia's Here digital mapping business

The fight for control of Nokia's Here digital mapping service appears to have drawn to a close as a consortium of German automakers has announced a deal to jointly acquire the business from the Finnish telecom giant. As anticipated, ownership in Here will now be taken over jointly by Audi, BMW, and Daimler, beating out reported rivals bids from the likes of Apple and Uber. Here is one of the largest and most advanced digital mapping and location systems. It started out in Chicago in 1986 as Navteq before Nokia acquired it in 2007, and is now slated to change ownership again. The cloud-based service maintains high-definition digital maps for nearly 200 countries and supports over 50 languages, gathering data from users to update the data continuously. Rather than transition the service into their own proprietary technology, however, the automakers insist that it will remain open "to all customers from the automotive industry and other sectors." Ownership will be shared equally between the three companies, with "none of them seek[ing] to acquire a majority interest" in Here. For another, Here's management is promised to remain independent, and "the consortium will not interfere into operational business." Though the purchase price has not been disclosed, it is rumored to be worth in the neighborhood of $2.7 billion. Assuming it passes regulatory approval, the acquisition is slated to be completed in the first quarter of next year. The German automakers anticipate implementing the service to provide connected vehicles with accurate, up-to-date information on road and other conditions. Examples it outlines include warning other drivers of icy conditions based on outside temperature and ABS activation. It could also warn drivers of impending traffic jams, or even guide traffic through green lights in an urban environment. In the future, the highly detailed maps are envisioned to enable fully automated driving as well.
