These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

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.

Daimler CEO Zetsche answers 'Most likely' to question of a Maybach SUV

When Dieter Zetsche was asked about the possibility of getting Maybach, the reimagined Mercedes-Benz ultra-luxury sub-brand, into the premium SUV game, the Daimler CEO reportedly told Auto Express, "Most likely." Those two little words aren't a firm answer – let alone an indication of timing – but we wouldn't be shocked to find out Mercedes is already working on one. Range Rover has gone even more upscale, the Bentley Bentayga is coming this year, as will the Maserati Levante. Rolls-Royce is deciding on an SUV this year (we think it's only a matter of time before they say "yes"), the Lamborghini Urus is still expected in 2018, Aston Martin is raising funds to build a crossover, and there have been rumors of a BMW X7 and Audi Q9 for years. Point being, everyone is busy writing their own invite to this ultra posh party. The latest comments would appear to put to rest any will-they/won't-they questions around a high-riding Maybach offering. There were rumors last summer that a GL-Class SUV (a model range shortly to be known as GLS-Class) with revamped styling and lots of luxury touches would join the top-tier sub-brand, but then in November, Mercedes' global head of sales and marketing told Automotive News, "I don't want to categorically rule anything out, but at this stage we have no plans for it [a Maybach SUV]." If and when a Maybach utility does become official, we'll only be picking up where we left off with the brand's previous incarnation: a GL-based Maybach was rumored way back in 2007.
