2016 British Grand Prix kept mostly calm and carried on

Three bursts of chaos decided the course of the British Grand Prix. The first was a literal cloudburst a dozen minutes before the race, which poured water on the Silverstone Circuit while drivers sat on the grid. Six minutes before the lights-out, the race director decided to start the race behind the Safety Car. The field loped around the wet track for five laps. When the Safety Car pulled off, the three leaders – Mercedes-AMG Petronas' Lewis Hamilton, followed by teammate Nico Rosberg and Red Bull's Max Verstappen – stayed out. Behind them, the second chaotic moment occurred: a big group of drivers made pit stops for intermediate tires. When Manor's Pascal Wehrlein spun at Turn 1 on Lap 7, officials issued a Virtual Safety Car. With the rest of the field slowed down, the three leaders ducked into the pits on Lap 8 for intermediates. The fortuitous timing meant all three drivers rejoined the track in their original positions. By Lap 9, with racing resumed, Hamilton had a 4.9-second lead on Rosberg. From that point, even as the track dried, no one bothered Hamilton during what one commentator called "a measured drive." The Brit won his home grand prix, taking the checkered flag seven seconds ahead of Rosberg. Rosberg had to earn second place on track. The German's car didn't respond well to the intermediate tires, so Verstappen excecuted an outstanding pass on Rosberg on the outside through Chapel on Lap 16. After everyone switched to slicks, Rosberg's Mercedes reclaimed its mojo and the German hunted Verstappen down, passing the Dutchman on Lap 38. The final touch of chaos happened when Rosberg's gearbox threw a tantrum on Lap 47 of the 52-lap race. Rosberg radioed his engineer, "Gearbox problem!" His engineer replied, "Affirm. Chassis default zero one. Avoid seventh gear, Nico." The race stewards allowed the engineer's first two statements, but stewards said the instruction about seventh gear contravened the rule that "the driver must drive the car alone and unaided." After the race, officials added ten seconds to Rosberg's time, demoting him to third behind Verstappen. Rosberg's is the first penalty arising from radio communication restrictions. Unsurprisingly, Mercedes will appeal. At this year's Baku race the radio controversy stemmed from engineers refusing to tell drivers what to do. Now we know what happens when the pit wall gets loose lips.

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 S-Class Magic Body Control ad is clucking awesome

This is a new ad from Mercedes-Benz. At no point does it show an automobile. Instead, it stars animals, but not the sort you might normally see in car commercial. This ad is all about chickens. It is bizarre, to say the least, with Diana Ross and the Supremes belting it out in the background, but it all kind of comes together when you realize just what Mercedes is hawking (yeah, pun intended).
It's for the manufacturer's Magic Body Control, found on the new S-Class. The system basically analyzes the road and prepares the suspension accordingly, leading to a ride that is, in the words of our own Chris Paukert "nothing short of spooky." You can read about it in our full review of the 2014 S550. Take a look below for the 53-second spot.
