Mercedes-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.

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 teases massive new Maybach coupe

Mercedes-Benz hasn't done a lot with its Maybach brand over the last few years. After killing the slow-selling standalone Maybach line, the badge sat unused, until MB slapped it on a luxed-out S600. But today, Mercedes posted a teaser of a new, two-door Maybach on its social media channels. Immediately given away by the Maybach badge on the C-pillar (and possibly one on the nose), we could be looking at a modern-day Exelero – a successor to Maybach's last coupe, a one-off, 700-horsepower rocket ship that deserved all the Darth Vader's car cliches – capable of extremely high speeds and stunning comfort. Everything from the long hood (better to accommodate some monstrous V12 engine) to the windshield's aggressive rake, to the absurdly long tail, signals a 200-mile-per-hour-plus top speed for this concept. And yes, we're thinking this is a concept. Kick the exposure way up with Photoshop and you can see that the side mirrors are too slim to actually function as normal mirrors – they're almost certainly cameras. Other details? Whatever Mercedes calls its new Maybach, it's going to be huge. According to the caption accompanying the teaser, this car is six meters (19.6 feet) long – that's over three feet longer than an S-Class Coupe and nearly four feet longer than a Bentley Continental GT. Like we said, it's enormous. And that's about all we know. Mercedes dropped this teaser out of the blue, nearly two months before the auto show season kicks off in Paris. It's possible the company could continue to tease out a new Maybach concept until early October, but more likely, we'll see an online debut ahead of the Paris show. Stay tuned.
