Race Recap: Abu Dhabi GP is reversals, luck, leanness and last dances

We weren't sure if Alter Ego Nico Rosberg, the one who flew into Brazil and showed Mercedes AMG Petronas teammate Lewis Hamilton that he knew also knew how to grab an entire race weekend by the scruff of the neck, arrived in Abu Dhabi. In both Friday practice sessions Hamilton showed Rosberg the way. Then on Saturday, Alter Ego Rosberg took over, taking the last Free Practice session and then pole position by a whopping four-tenths of a second over Hamilton. Thanks to the gimmicky and soon-to-be-obliterated spectre of double points, if Rosberg won the race and Hamilton finished lower than second, the World Championship would remain in German hands. Behind Hamilton came the Williams duo, again, with Valtteri Bottas ahead of Felipe Massa. Daniil Kvyat did swell to put his Toro Rosso in fifth, Jenson Button was just as swell getting his McLaren into sixth. Kimi Raikkonen outqualified his Ferrari teammate Fernando Alonso for the third time this year, the pair taking seventh and eighth on the grid. Kevin Magnussen lined the second McLaren up in ninth, Jean-Eric Vergne making the top ten for Toro Rosso in his last race for the team. To be clear, that was the final grid for race: Daniel Ricciardo and Sebastian Vettel had both qualified in the top ten but were sent to the back of the grid when their Infiniti Red Bull Racing front wings were deemed illegal. They'd start from the pit lane, which was still ahead of Romain Grosjean in the Lotus, who took so many penalties for new engine components that he started the race in Turkey. At lights-out on Sunday, well, it was pretty much lights out. That's when Hamilton got the start of the year, bolting off the line so quickly it didn't take him 100 meters to get in front of Rosberg. The Brit took Turn 1 in the lead, then laid more than a second into the German on the first lap. Rosberg kept close, about 2.5 seconds back, but it was Hamilton's race to lose and everyone knew it; barring a reliability issue or the kind of driving mistake Hamilton hasn't made all year, Britain would have its fourth double world champion. Rosberg was left asking his engineer what kind of strategy they might use to claim first place. That reliability issue did come, but it struck Rosberg on Lap 26 when his entire Energy Recovery System failed, robbing him of 160 horsepower and taxing his brakes.

2014 Mercedes-Benz B-Class ED has 87-mile range, 84 MPGe

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog. Let's say up front that the 87-mile single-charge range of the Mercedes-Benz actually stacks up nicely against its competition, since that distance puts the new model right in line with the Nissan Leaf and BMW i3 (we'll ignore the Tesla Model S for a second, here). You can find the numbers at the US Department of Energy's FuelEconomy website. As far as miles per gallon equivalent ratings, though, the Benz's steel frame makes it come up short, as it's about 1,300 pounds heavier than the carbon-fiber-body i3 and about 600 pounds heavier than the Leaf. The B-Class EV has a bigger battery than the i3 or the Leaf (36 kWh compared to 22 kWh for the i3 and 24 kWh for the Leaf) and that's one reason the car gets an 84 MPGe rating, which is about 26 percent less than the Leaf's and 32 percent less than the i3's. But at least the local utility companies will be happy. Mercedes-Benz priced the 177-horsepower B-Class ED in April at $41,450, or $100 more than the i3.

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.
