F1's Vettel leads, Verstappen and Grosjean crash at Silverstone

SILVERSTONE, England — Ferrari's Sebastian Vettel pushed Formula One title rival and home race favorite Lewis Hamilton off the top of the British Grand Prix practice timesheets on Friday while Max Verstappen crashed. Hamilton, winner for the past four years at Silverstone, had started the day by leading a Mercedes one-two in the sunny opening session. Vettel, who leads the Briton by a point in the championship after nine races, put in a lap of 1 minute 27.552 seconds in the afternoon to end the session 0.187 faster than his fellow-four-times world champion. That was still slower than Hamilton's morning time of 1:27.487, however, with Vettel third then and half a second slower. Hamilton's Finnish teammate Valtteri Bottas, with a new engine in his car after last weekend's mechanical retirement in Austria, was second and third fastest respectively in the two sessions. Australian Daniel Ricciardo and Kimi Raikkonen traded fourth and fifth places while Max Verstappen, winner in Austria for Red Bull, was sixth in the morning but crashed after lunch without setting a time. The 20-year-old Dutchman had ended the first session early after he was told to stop the car. Haas's Romain Grosjean had a heavy crash at the fast first corner, slamming into the tire barriers after failing to close the drag reduction system (DRS), in the morning and did not take part in practice two. "The car is destroyed," the Frenchman, who was unhurt in the impact, said over the radio. "I'm very, very sorry guys. I think it was the bump. I missed the (DRS) button." Team boss Guenther Steiner said the team needed to rebuild the chassis. Grosjean's team mate Kevin Magnussen and McLaren's Fernando Alonso were called to see stewards for a "potentially dangerous maneuver" after an incident between them early on but stewards ruled there was no further action needed. "Magnussen tried to hit me two times - in one and three," Alonso reported over the radio. "Very dangerous."Reporting by Alan BaldwinRelated Video: This content is hosted by a third party.

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.

Mercedes-Benz CLA45 AMG coming to the New York Auto Show

Mercedes-Benz showed off the CLA45 AMG at a private event on the eve of the Geneva Motor Show, but was determined not to let it be photographed. We can talk about it, though - after all, a teaser image was released to promote the new Sony game Drive Club. The CLA45 AMG will use the same powertrain as the A45 AMG, which means a 2.0-liter turbocharged four-cylinder with 360 horsepower and 332 pound-feet of torque. And that means a small four-door coupe sedan with the highest horsepower-per-liter in the segment. It will shift through the same seven-speed dual-clutch transmission, should also run out of speed at 155 miles per hour and have that three-stage stability control system.
As with its hatch sibling, the CLA is already so aggressive on the outside - and the parent company so anxious not to demolish the sedan's 0.22 coefficient of drag - that not much has been done to the cranked-up CLA. Even the rather thin tires on the standard only get a little less thin on the hotter variant. Inside will be the telltale AMG signs, with lots of red detailing and that flat-bottomed wheel among the giveaways. We'll know more later this month when the wraps come off at the New York International Auto Show.
