2015 Mercedes-Benz S550 PHEV offers the best of both worlds it's ready to conquer

The Mercedes-Benz S-Class just keeps growing – both in terms of dimensions and in terms of variants. Nevermind the S-Class Coupe for a moment and focus only on the sedan: in North America alone, you can get the big Benz in S550, S600, S63 and S65 spec, and at the Los Angeles Auto Show this year, Daimler has rolled out the new Maybach version as well. But if it's a more environmentally friendly way to woosh around town in serene luxury that you're after, you'll want to look at the new S550 Plug-In Hybrid. Joining Daimler's growing range of battery-powered models alongside the E400 Hybrid, B-Class Electric Drive and Smart ED (the latter soon to be replaced by an all-new version), the S550 PHEV is the German automaker's first plug-in hybrid. It was first announced over a year ago and made its debut at the Frankfurt Motor Show last year, but now the US-spec car is making its North American debut in LA. Promising "the performance of a V8 and the fuel consumption of a compact model," the S550 PHEV pairs a 3.0-liter twin-turbo V6 to an 80-kW electric motor, the S550 PHEV packs a combined 436 horsepower and 479 pound-feet of torque to reach 62 in just 5.2 seconds, top out at 130 miles per hour or drive up to 20 miles on electric mode alone. On the European combined cycle, it'll return an impressive 84 miles per gallon, all the while never skimping on the luxury. Scope it out in our gallery of photos from the show floor in LA and delve into the details in the press release below. First PLUG-IN HYBRID with a star: S550 PLUG-IN HYBRID The new Mercedes-Benz S550 PLUG-IN HYBRID blends an ultramodern hybrid drive configuration with the unique innovations and the luxurious equipment and appointments of the S-Class. The luxury sedan impresses with exceptional dynamism and efficiency. Thanks to standard pre-entry climate control it also offers unique climate comfort. The first certified three-liter luxury sedan in the world is a further milestone on the road to emission-free mobility. "The S550 PLUG-IN HYBRID is the first luxury sedan with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and a high-tech hybrid drive," says Prof. Dr.

Recharge Wrap-up: BMW i3 goes against Mercedes B-Class ED, Tesla good for business

Car and Driver has published a comparison test pitting the 2014 BMW i3 against the 2014 Mercedes-Benz B-class Electric Drive. The test not only measured the quality of the driving experience, but also all the quantitative details that are especially important when looking at electric vehicles. For instance, the Benz's real-world MPGe surpassed its own rating, but it still couldn't match the BMW. The B-Class, though, won in the range department. We won't spoil all the results, or Car and Driver's overall pick, but you can head over to the article to find out for yourself. Tesla's expanding business, including the Gigafactory being built in Reno, NV, is encouraging growth in the locales and associated businesses. Some of Tesla's suppliers are talking of relocation, wanting to be close to the action stirred up by the electric automaker's expansion. It makes good business sense to be in the same neighborhood as Tesla. "We can react quickly, and our engineers are constantly working with Tesla," says Futuris General Manager Sam Coughlin. Brookings Institute fellow Jennifer Vey says, "The land around Tesla is being redeveloped and reimagined. It's a mash-up of an anchor campus, startups, housing and transit, in a physically compact area where companies can cluster and connect." Read more at San Jose Mercury News. EVs are doing even more to reduce energy use clean up the air, according to new analysis from the Union of Concerned Scientists. According to findings, 60 percent of Americans now live in areas where EVs do more to reduce emissions than hybrids, up from 45 percent in 2012. Average electricity use is now 0.325 kWh per mile, down five percent from 2011. EV performance - in terms of mileage and emissions - is improving compared to traditional fuel vehicles, based on the sources of electricity in various regions.

Zipcar is expanding across Europe, and has already established itself in Austria, Spain and the UK. According to Zipcar France's General Manager Etienne Hermite, "In a highly populated city, Zipcar's model has been proven to remove up to 15 personally owned vehicles from the road for each Zipcar in service, reducing parking demand, congestion and emissions." Zipcar European President Massimo Marsili hopes that most Parisians will eventually be just a short walk from a Zipcar.

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.
