2015 Italian Grand Prix is smoke, mirrors, stalls, and stewards

For the first day-and-a-half of the Italian Formula One Grand Prix weekend, everything went to blueprint: Mercedes in front, Ferrari lurking, everyone else scrambling in their usual orders behind. Then qualifying came, and someone stirred the pot. About the only thing we expected was for Lewis Hamilton to put his Mercedes-AMG Petronas on pole position, the 11th time he's done it this year. He did it with a brand-new specification engine, one that represents not only an evolution in components, but also in power unit philosophy. Kimi Raikkonen lines up in second. It's been a long time since we read those words; the Iceman hasn't been on the first row since the 2013 Chinese Grand Prix, when he put his Lotus second on the grid behind... Lewis Hamilton. Raikkonen lined up just ahead of a Ferrari at that China race, then driven by Fernando Alonso. In Italy this weekend, he lined up in front of the Ferrari driven by his teammate, Sebastian Vettel, who qualified third. Both Ferraris benefitted from an upgraded power unit, ending a front-row drought for the scuderia that goes all the way back to Monaco in 2009 Germany in 2012. Nico Rosberg has a lot of work to do from fourth in the second Mercedes-AMG Petronas. Mercedes discovered a problem with Rosberg's engine but couldn't figure out the cause, so he reverted to the previous-spec engine he used in Belgium, one that's six races old. The lack of power hurt. Williams teammates Felipe Massa and Valtteri Bottas took fifth and sixth, with Massa seemingly given a team-ordered helping hand. Williams told Bottas to tow Massa down the front straight, giving Massa a blistering time in the first sector. Then Bottas did it again, ensuring he would line up behind Massa. The first Sahara Force India of Sergio Perez nabbed seventh, three places ahead of teammate Nico Hulkenberg in tenth, with Romain Grosjean in the Lotus behind Perez in eighth. Marcus Ericsson in the Sauber qualified ninth, but some clumsy driving saw him impede Hulkenberg twice. The stewards penalized Ericsson with a three-place grid penalty and two points on his superlicense, so Hulkenberg inherited ninth and Pastor Maldonado in the second Lotus inherited tenth. We hardly saw Hamilton during the race, because he led from the start, worked up a larger gap to second place on every lap, and didn't give up the lead for the whole event.

Mercedes-Benz C350 Plug-In Hybrid promises 20 miles EV range, 5.9 seconds to 60

Mercedes-Benz has introduced its first hybrid C-Class to the US market with the new C350 Plug-In Hybrid. Despite its fuel-saving purpose, though, this C is not short on firepower. MB paired a 208-horsepower, 258-pound-foot, turbocharged four-cylinder with a 80-hp, 251-lb-ft electric motor for a potent overall output of 275 hp and 443 lb-ft of torque. That translates a 0-60 time of just 5.9 seconds and a top speed of 130 miles per hour. For those that aren't interested in such frivolous numbers, though, the C-Class can still impress in more environmentally friendly ways. It can cover 20 miles to a charge and will hit speeds of up to 80 miles per hour (although not likely at the same time). Naturally, fuel economy figures aren't available at this early stage. Beyond those powertrain changes, the C350 Plug-In is still the same relaxed, luxurious baby S-Class, with a class-leading interior that should really benefit from the quiet ride provided by an electric powertrain. Take a look at our full gallery of live images of the new C-Class hybrid, straight from the Detroit's Cobo Hall.

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.
