Camaro SS facelift and dune-riding the new Mercedes-Benz GLS | Autoblog Podcast #579

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Reese Counts and Associate Editor Joel Stocksdale. First, they talk about the newly refreshed Chevy Camaro SS. Then they dish on the cars they've been driving, including the Lexus UX, Lexus GS F and Volvo V90, as well as riding in the new Mercedes-Benz GLS. After that, they ask the question, how many AMG cars is too many? Finally they turn to car buying, and suggest potential vehicles for a shopper on Reddit for the "Spend My Money" segment.

Race recap: 2016 Australian F1 Grand Prix a rowdy start to season

The three brief Formula 1 tests ahead of the current season belied how much had gone on since the last race in November: Infiniti subbed out for Tag Heuer, Renault is back, the all new Haas F1 team, a revamped Manor, three brand new drivers and two returning drivers, a raft of regulation changes among the newly tilled soil. The four engine manufacturers spent a combined 67 tokens among the 138 in the kitty, Renault using just seven of their 32. The only conclusive proof to come from the annual intermission was the otherworldly capability of Mercedes-AMG Petronas. The Silver Arrows didn't even try the super- and ultra-soft tires, focusing on reliability instead of speed. The result? They ran more than 19 race distances, obliterating the lap totals of every other team. There are certainly a few people who enjoyed the complicated new rolling-elimination qualifying format fast-tracked to approval just a few weeks ago. They were wildly outnumbered by those who thought it was awful, including the same team heads who voted for it. We'd probably have to go back to the debacle at the 2005 Indianapolis Grand Prix for an equivalent fiasco when Michelin pulled its teams over safety fears, leaving six cars out of 20 to qualify. In Australia, within 24 hours of the conclusion of qualifying, the new format had itself been eliminated. Nevertheless, qualifying also taught us what didn't happen over the winter: any other team progressing enough to outduel Mercedes. After admitting that he dropped off after winning the championship last year, then getting questioned in the press for some dubious off-season activities, Lewis Hamilton proved he can still turn it on when he wants to. The Brit smoked the Albert Park track in 1:23.837, more than three-tenths of a second ahead of teammate Nico Rosberg in second place. Ferrari did make strides during the off-season, but only enough to keep the same gap it had to Mercedes last year: Sebastian Vettel lined up third, a half-second behind Rosberg, teammate Kimi Raikkonen another four-tenths back in fourth place. Max Verstappen said Toro Rosso is the best of the rest, the Dutchman taking fifth place in front of Felipe Massa for Williams in sixth and Toro Rosso teammate Carlos Sainz in sixth. Daniel Ricciardo – who wasn't smiling after qualifying – kept Red Bull and its new "Tag Heuer" engines in the conversation with eighth on the grid.

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.
