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 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.

New Forza 6 car pack adds 1,000 hp German race truck

Today, Forza Motorsport 6 continues its pattern of monthly updates with seven new cars in the Turn 10 Select Car Pack. The diverse group of cars spans nearly 60 years of motoring history with a combination three street and four track cars from Germany, Italy, the UK, and the UK. Turn 10 Studios will also release an update that brings back Monza, Catalunya, and the Circuit of the Americas tracks. The seven vehicles in the pack are the 1957 BMW Isetta 300 Export, the 1969 Ford Brawner Hawk III, the 1980 Fiat 124 Sport Spider, the 2014 Jaguar #14 Emil Frey GT3 Jaguar XK, the 2014 Chevrolet #4 ROAL Motorsport RML Cruze TC1 WTCC, the 2015 Mercedes-Benz #24 Tankpool24 Racing Truck, and the 2015 McLaren 570S Coupe. The BMW, Fiat, and McLaren all represent iconic vehicles for their respective brands. While the BMW may not be fast and the McLaren is the baby of the brand, their importance can't be overstated. It also can't be a coincidence that Fiat is releasing an all-new 124 Spider, now based on the Mazda MX-5 Miata, just as Forza is adding in a version of the original. The racecars share a similar iconic nature. The Ford Brawner Hawk III won the 1969 Indianapolis 500 with Mario Andretti at the wheel. The team behind the GT3 XK has ties with Jaguar going back decades. The Chevrolet Cruze is one of the most successful cars in the history of the World Touring Car Championship. Finally, the Mercedes-Benz racing truck was added because the developers saw them in real life and thought racing these big trucks would be cool. The car pack is available to for $7 total, or players can purchase each car individually. Related video: Related Gallery Forza 6 Car Pack Toys/Games BMW Fiat Mercedes-Benz forza car pack
