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.

2015 Monaco F1 Grand Prix race recap [spoilers]

Lewis Hamilton came to Monaco with a new three-year deal with Mercedes-AMG Petronas and a vow to not let anything, including any "mistakes" by teammate Nico Rosberg, stand in the way of his best qualifying effort. Mercedes reportedly made it rain with a 100-million-pound deal, and Hamilton made it rain right back with his first pole position at Monaco. Rosberg did make a mistake but this time it was behind Hamilton, which meant he stuffed-up the qualifying attempts of rival drivers like Sebastian Vettel. So Rosberg starts second, 0.342 behind Hamilton but 0.449 ahead of Vettel in the Ferrari. Daniel Ricciardo thinks he should have been third, but a communication error with his engineers left him in the wrong engine setting for his final hot lap, so by the very first corner he'd lost the time he would have needed to get higher than fourth on the grid. The second Infiniti Red Bull Racing of Daniil Kvyat slots in behind him, ahead of the second Ferrari of Kimi "Not A Very Happy Day" Raikkonen, who just can't get it going lately. Sergio Perez did for the Sahara Force India what the car can't do on its own, which is grab a top-ten qualifying spot. Toro Rosso rookie Carlos Sainz had qualified eighth but missed a call to the weigh bridge, so he's been slapped into the pit lane. Pastor Maldonado in the Lotus inherits his eighth place, ahead of rookie Max Verstappen in the second Toro Rosso, and Jenson Button in the McLaren. Button only got up there because of two penalties: for Sainz, and Romain Grosjean who had qualified 11th but took a penalty for a gearbox change. Want to know how hard it is to do better on race day than in qualifying at Monaco? Even the never-say-die Fernando Alonso said, "Monte Carlo is a train of cars on Sunday, the race finishes on Saturday afternoon." Well obviously, he didn't take Max Verstappen's seek-and-destroy tactics into account. The young Dutchman had made passing look like a real option in Monaco, getting past Maldonado at St. Devote on Lap 7 after a bit of argy-bargy on Lap 6, then taking advantage of blue flags to slink past teammate Carlos Sainz and Williams driver Valtteri Bottas while hiding in Sebastian Vettel's slipstream. He tried the same move on Romain Grosjean on Lap 65, but Grosjean locked him out. Verstappen lined up the Lotus driver over the following laps, then looked like he slipped to the inside at St.

Ford Mustang Shelby GT350R named Road & Track Performance Car of the Year

With a 526-horsepower, 5.2-liter V8 that roars to 8,250 rpm, it's really hard to consider the 2016 Ford Shelby Mustang GT350R an underdog in any fight. However, the Shelby held the lowest as-tested price and was only middle of the pack in terms of power in Road & Track's 2016 Performance Car of the Year challenge. The 'Stang's numbers clearly didn't tell the whole story about the potent coupe because Ford's muscle car grabbed the title in this year's test. A model needs to be new or significantly updated to be eligible for the honor, and R&T found an impressive slate of eight candidates this year. The challengers included the Bentley Continental GT3-R, Cadillac ATS-V Coupe, Chevrolet Corvette Z06, Dodge Viper ACR, Mercedes-AMG GT S, and Porsche Cayman GT4. The Ferrari 488 GTB was the most expensive of the bunch with an as-tested price of $347,942, which is five times more than the Shelby. Once the group was together, R&T hustled them over curving roads and on the National Corvette Museum Motorsports Park. There was a lot to love about the Shelby, even in this impressive crew. "With a flat-plane crank and Sport Cup 2 tires, the GT350R is a Mustang turned up to 11," editor-in-chief Larry Webster said in the announcement of the results. The GT350R joins some great company. Past winners include the Porsche 911 GT3 last year and the Corvette in 2013. For some fantastic photography and the complete appraisal of these performance machines check out R&T's website for the full story.
