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.

Brabus luxes up new Mercedes V-Class

Looking for a luxury coach to get you around town in style and comfort, but don't need anything as big as a Sprinter? Mercedes will gladly point you towards the smaller V-Class, trading Stateside as the Metris. And now Brabus has released a full array of customization options for the van as well. The list of modifications available from the venerable Benz tuner include an aero kit to give the van a sleeker look while reducing front-end lift, a full complement of 18- and 19-inch wheel options, a retuned suspension, engine enhancements, exhaust upgrade, and a fully refitted interior. The first-class cabin on this show vehicle has been reupholstered in leather and Alcantara, offset by wood and carbon-fiber trim, and a complete entertainment system. It includes a pair of 15.6-inch LCD screens that drop from the headliner and WiFi. Finally, there's a touchpad integrated into the interior C-pillars to operate the system as well as the lamps, heated seats, power windows and curtains, and the sliding doors. Accommodation is clearly the emphasis here. But Brabus being Brabus, it has also optimized the BlueTec four-cylinder turbo diesel engine to produce 44 more horsepower and 52 pound-feet more torque. With output now up to 232 hp and 376 lb-ft, the van will reach 62 miles per hour from a standstill in 8.8 seconds and top out at 130 mph – and look that much slicker in the process.

BRABUS upgrades the people mover with powerful engine tuning, an exclusive appearance package, tailor-made wheels and an individual entertainment concept. A sporty-elegant design is the trademark of the BRABUS aerodynamic-enhancement kit for the new Mercedes V-Class and Vito. All components are manufactured from PUR in OEM quality, giving them a precise fit and making them easy to paint. To give the vehicle an even more distinctive face, the BRABUS designers have developed attachments for the side air intakes, which can be complemented with auxiliary LED side markers, and a front spoiler that attaches to the lower section of the bumper.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
