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.

EVO "2012 Car of the Year: The Track Battles" is a sports car salmagundi

EVO has come out with another gotta-watch-it video, throwing its 2012 Car of the Year contestants around the UK's 1.5-mile Blyton Park track. It's actually a 15-minute teaser for the full-length DVD detailing the magazine's Car of the Year selection, but the tease is worth every penny free second.
Tiff Needell and sports car racer Richard Meaden handle the wheel duties, the two driving five pairs of sports cars: Lotus Exige S vs. Porsche Boxster S, Morgan Three-Wheeler vs. Toyota GT86, BMW M135i vs. Porsche 911, Mercedes-Benz C63 AMG Black Series vs. Alpina B3 GT3, the marquee event pits the McLaren MP4-12C vs. the Pagani Huayra. After a head-to-head lap with commentary during drifts, Meaden takes each car out to set a representative lap time.
You'll find the verdicts, lots of tire smoke, and lines like "Anything you can do sideways I can do sideways" in the video below.

Lego provides one of the cheapest ways to own a Bugatti Chiron

Just over a month ago, we got a look at one of the latest Lego Speed Champions sets when Ford revealed the GT and GT40 kit. Now we get to see the rest of the lineup, and it's chock full of F1 and supercar goodness. The official Lego images show that the Bugatti Chiron, Mercedes-AMG GT3, Ferrari FXX K, and F1 cars from Ferrari and Mercedes all made the cut. Each set gets some unique features and most include interchangeable wheel covers. The Chiron comes with some tiny cones suitable for desk slaloms and the Mercedes-AMG GT3 gets an alternate nose. The FXX K comes has the most impressive selection of accessories, though, as it includes a dyno and engine run stand. The F1 sets are divided similarly, but with Mercedes getting more extras. The Brick Fan also reports that the Mercedes kit may be exclusive to select stores. The Ferrari kit only comes with a starting light, but the Mercedes set includes a garage, starting lights, and winner's circle. It'll be up to you whether you put Hamilton or Rosberg in that winner's circle. According to The Brick Fan, these kits are set for release in winter 2017. Since the Ford GT set has a release of March 1, we expect the rest will hit stores in the next couple of months. They're sure to be great additions to anyone's existing Lego garage.
