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.

Rosberg survives the Mexican mess | 2016 Mexican Grand Prix recap

Roughly ten messy laps defined the Mexican Grand Prix – five laps at the start and five at the end. Those laps included a couple of actual wrecks and a few more near wrecks that turned the entire day into chaos. To have any chance of winning the 2016 Driver's Championship, Lewis Hamilton needed to get his Mercedes-AMG Petronas across the finish line ahead of teammate Nico Rosberg. Once again we got a weekend full of vintage Hamilton, the Brit dominating the from Friday to Sunday, except for the first corner of the first lap. Pole-sitter Hamilton reached Turn 1 clearly in front of the field. But he couldn't make the corner and stay on track, so he zipped into the runoff area and over the grass, rejoining at Turn 3 still ahead of the field. The stewards didn't penalize Hamilton, one commentator's explanation being that Hamilton "was not battling another car." The non-action left car #44 to enjoy a lights-to-flag win. At that very same corner, Rosberg also availed himself of the runoff area. His infraction seemed destined to incur a penalty until replays showed that Max Verstappen in the Red Bull slid wide and bumped Rosberg, causing the German to go off track. No penalties were handed out there, either. Verstappen would return to hound Rosberg later in the race when angling for second place. Verstappen took a stab through Turn 4 on Lap 50 of the 71-lap race, but ran off the track and lost touch with the Mercedes by Lap 55. Ferrari got half of its strategy right in Mexico, putting Sebastian Vettel hard on the charge in the final stint. The German got within DRS range of Verstappen on Lap 67, with Red Bull's Daniel Ricciardo a little more than a second behind Vettel. On Lap 68, Verstappen pulled the same move as Hamilton at the beginning of the race: the Dutchman ran wide through Turn 1, zoomed over the grass and rejoined the track at Turn 3, staying ahead of Vettel the whole time. With three laps remaining, the stewards chose to investigate after the race. In spite of Verstappen's own team telling he probably needed to cede position to Vettel, Verstappen stayed in front and slowed just enough to put Vettel under threat from Ricciardo. On Lap 70 Ricciardo had closed up to Vettel's gearbox. Headed for Turn 4, Vettel swung outside to take the corner. When Ricciardo moved inside to pass, Vettel moved inside to block the Aussie while both cars were in the braking zone. The Ferrari made light contact with the Red Bull, but Vettel held his position through Turn 5.

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.
