Mercedes-Benz says no to price premium on S550 PHEV

The good news? Mercedes-Benz won't be charging any extra for the plug-in hybrid version of the S550 sedan compared to the gas-powered version. The bad news? The gas-powered version is really expensive. The S550 Plug-in Hybrid's pricing will start at a tidy $95,325, the same as the conventional S550, according to Cars Direct. For that price, buyers get a car that delivers 436 horsepower and 479 pound-feet of torque while having the ability to go as far as 18 miles on electric power alone, assuming that the driver in question isn't trying to use all 436 horses. But just in case he or she is, the car can also go from 0 to 60 miles per hour in about five seconds. There's been no word on a fuel-economy rating from the US Environmental Protection Agency (EPA) but the sedan gets 84 miles per gallon on the more lenient European driving cycle. It's unlikely to anywhere close to that stateside, but some folks still might feel they got their money's worth (ha ha) by adding a plug. The S550 Plug-in Hybrid goes on sale in California later this month. The model was first unveiled at the Frankfurt Auto Show in 2013 and shown off at the Los Angeles Auto Show late last year.

Mercedes-Benz S-Class spied once again

As evidenced by how little camouflage the next-generation Mercedes-Benz S-Class has been caught wearing lately, it can't be too much longer until the car will get its official debut. In our newest shots of the yacht-sized luxo sedan, the cladding still covers up the headlights, front fascia and most of the rear end, but we finally have an almost undisguised look at the rest of the car's lines.
Considering previous spy shots had more camo that better (or fully) concealed the S-Class' body, some of the more obvious things we see in these images include the prominent grille, the CLS-Class-inspired bodyside creases, the pointed trunk opening and, most interestingly, a lack of fancy exhaust outlets. Unlike other S-Class prototypes we've seen, this car does not have integrated outlets, but it does have two pipes on the left side of the car. All current S-Class models in the US and Europe feature a dual exhaust layout on each side of the car, so while some of our questions about the car get answered, it would appear that more are just arising.

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.
