2016 Malaysian Grand Prix recap: Surprises and missed opportunities

Mercedes-AMG Petronas pilot Lewis Hamilton drove so well in the run-up to the Malaysian Grand Prix that he said before the race, "Honestly, I don't feel anything is going to stop us." On Sunday, the Sepang race showed what it thought of plans and predictions. Heading into the right-hand Turn 1, Sebastian Vettel practically recreated the dust-up at the Belgian Grand Prix three races ago. When Mercedes' Nico Rosberg swept across from the outside line toward the apex, Red Bull's Max Verstappen had to jink right to avoid, touching Vettel's Ferrari on the inside. Vettel speared straight on and hit Rosberg. Vettel's left front suspension broke, ending his race. Rosberg spun and got moving again, but at the back of the pack. That appeared to put Hamilton on a clear run to the checkered flag. His car looked perfect, his pace was perfect, he easily kept Red Bull's Daniel Ricciardo and Verstappen behind. A result that would have seen Hamilton retake control of the Driver's Championship – at Petronas' home race – got crushed on Lap 41 when Hamilton's engine blew down the main straight. That put Ricciardo in the lead, followed closely by his teammate. Just two laps before Hamilton's exit, Ricciardo and Verstappen had battled for second place with some of the best driving we've seen all season. Ricciardo drove as if exorcising the demons of missed opportunities earlier in the year, keeping the young Dutchman behind. The two Red Bulls took the flag fifteen laps later in that order, clocking the first one-two finish for a team other than Mercedes since 2014. It's Red Bull's first one-two since Brazil 2013, when Vettel and Mark Weber took the top steps at the last race of the V8 era. Rosberg recovered to take third in spite of a ten-second penalty for an optimistic pass on Ferrari's Kimi Raikkonen. The Finn crossed the line 12 seconds later, followed by Valtteri Bottas in the Williams and Sergio Perez in the Force India. In another Belgium repeat, Fernando Alonso drove from the back of the grid to finish seventh. Nico Hulkenberg secured eighth, Jenson Button ninth for McLaren in his 300th grand prix, and rookie Jolyon Palmer scored his first point of the season for Renault in tenth. The issue to trump all others from now until next week's Japanese Grand Prix: Lewis Hamilton's terrible luck with engines. Power unit gremlins earlier this season helped drop the Brit to 43 points behind Rosberg after the Russian Grand Prix.

Mercedes-Benz A45 AMG shows up to fight the hottest hatches [w/videos]

Fun coincidence. On the same day that Audi announces the unveiling of its new S3 Sportback at the Geneva Motor Show, Mercedes-Benz steals the spotlight by confirming that the all-new A45 AMG will also receive its official debut early next month. Starting life as the entry-level A-Class hatchback, the A45 AMG gets the full AMG treatment, which includes numerous performance, handling and styling upgrades.
Under the hood sits an AMG-tuned 2.0-liter turbocharged I4 breathing through a sport exhaust system helping the five-door produce 360 horsepower and 332 pound-feet of torque. This engine is paired to a seven-speed AMG dual-clutch transmission and power is sent to the ground using 4Matic all-wheel drive. Mercedes-Benz says that the A45 AMG will be able to accelerate from 0-60 miles per hour in under 4.5 seconds and it will have a top speed of 155 mph; in the land of hot hatches, it doesn't get much hotter than that. For added performance and handling, AMG has retuned the A-Class' suspension and steering systems and equipped The A45 with a three-stage stability control system that is specific to this car.
Surprisingly, the exterior styling of the A-Class was already sporty enough that the new model doesn't receive too many changes to become the A45 AMG. The biggest alterations include black accents to the chin spoiler, rocker panels and mirror caps, black wheels with red-painted brake calipers and rectangular dual exhaust outlets. Inside, it doesn't take a trained eye to spot the differences. The flat-bottomed sport steering wheel and the numerous red accents throughout the cabin (including the seatbelts!) really help to make this AMG interior stand out; front passengers will also get sport bucket seats that appear to be more than supportive enough for even the most spirited driving conditions.

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.
