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.

Ford, Ram in heavy-duty towing spat

Every pickup truck commercial has the brand trying to convince us that its model is the biggest, brawniest vehicle on the block. But Ford and Ram appear ready to really throw down the gauntlet and scrap over the towing figures for their heavy-duty models, and it could potentially end up in court.
The issue revolves around what it means to be best in class. Ford claims that its 2015 F-450 (pictured above) has a max tow rating of 31,200 pounds, compared to 30,000 pounds for the Ram 3500 (right). However, both companies market these heavy haulers as having the top towing in their class. According to Automotive News, Ford is threatening legal action if Ram doesn't back down.
The situation isn't as simple as just comparing the numbers, though. First, the two companies calculate their towing capacities differently. Ram adheres to the SAE J2807 rating, while Ford uses its own internal system. Although, as the company introduces new models, they are certified using the SAE standard. "When an all-new F-Series Super Duty is introduced, it also will use SAE J2807," said Ford to Autoblog in an emailed statement.

2014 Ram ProMaster 2500

Front-wheel drive is what sets the all-new Ram ProMaster full-size commercial van apart from its competition. In a segment still choked with thirsty, rear-wheel-drive, ladder frame, pickup truck-based cargo vans, the American automaker is introducing something entirely new - well, new to our domestic market, as Europeans will recognize Ram's fresh entrant as a made-for-USA Fiat Ducato.
While the big ProMaster doesn't have a traditional body-on-frame chassis, it isn't a pure unibody either. Consider it a hybrid of both, with a unibody cab up front and a reinforced high-strength steel subframe in the rear. The platform employs double A-arms and MacPherson struts on the front axle, while the rear uses a simple tubular beam axle. Tires are 225/75R16 at all four corners. The steering is hydraulic rack-and-pinion (allowing an impressive 36-foot turning radius) and there are disc brakes with two-piston calipers all around. It is a solid, if unsophisticated, setup.
This game-changing van, which has already arrived in showrooms with a starting price of $28,630, is propelled by either a gasoline-powered 3.6-liter Pentastar six-cylinder (280 horsepower and 258 pound-feet of torque) or a new turbocharged 3.0-liter four-cylinder diesel (174 horsepower and 295 pound-feet of torque). Ram will offer a traditional six-speed automatic or a new six-speed automated single-clutch manual transmission that drops the hydraulic linkage to improve fuel economy - details are still emerging on this unique gearbox.
