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.

Man makes record-setting drive across the US in 28 hours, 50 minutes

Records, as the say, are made to be broken. Whether that's cramming the most hot dogs down your gullet, running a faster mile, or yes, driving across the United States, odds are that there's someone out there wants to eat more, run faster or drive harder. Speaking of that last example, the record for driving from a set location on the east coast, in particular the Red Ball Garage in Manhattan to the Portofino Hotel in Redondo Beach, CA, has been one that has fascinated gearheads since a guy named Cannonball Baker made the trek from New York to LA in 53 hours, 30 minutes, in 1933.
The competition saw its glory days when Car and Driver's Brock Yates came up with the Cannonball Baker Sea-To-Shining Sea Memorial Trophy Dash (more affectionately known as the Cannonball Run), although the record was most recently set by Alex Roy and his 32-hour, seven-minute trek behind the wheel of a BMW M5 in 2006. Now, there's a new champion, who made the trip from east to west in a scarcely imaginable 28 hours and 50 minutes, behind the wheel of a 2004 Mercedes-Benz CL55 AMG. That's works out to an average speed of 98 miles per hour over the course of 2,813.7 miles.
His name is Ed Bolian, and Jalopnik has a writeup of the epic voyage that details everything from the history of the Cannonball Run to Bolian's preparation and trouble finding co-drivers, to the trip itself. It is well worth a read.

Mercedes-Maybach Ultimate Luxury SUV concept shown in leaked images

Just days ago, we posted the interior teaser image Mercedes-Maybach released of its Ultimate Luxury concept due to be presented at the Beijing Motor Show. Now photos of the entire vehicle, inside and out, have leaked online courtesy of the manufacturer. Thanks to the concept's own microsite being live for a short while, we've gotten a good look of the concept. And it's not just a dressed-up GLS by any means, even if there might be a GLS platform underneath it all: It's a high-riding four door sedan with a clearly formed trunk instead of a traditional SUV shape. There's a big waterfall grille flanked by low, aggressive three-unit headlights, and the detailing is a combination of SUV cues and something a lot more luxurious. It's not easy to design a three-box sedan that's still recognizably an SUV. Inside, there's white leather and rose-gold detailing everywhere. But the big deal is the powertrain, which in the concept is all-electric. The all wheel drive is propelled with four electric motors, with a combined power output of 750 horsepower. The battery, said to be a flat underfloor design, is good for 80 kWh and an EPA range of over 200 miles, and the vehicle's top speed is limited to 250 km/h, or 155 mph. There's DC fast charging at up to 350kW, meaning that the range can be boosted by 60 miles in just five minutes, and induction charging is also available. All in all, the vehicle reminds us of the 2009 Lagonda Luxury Utility Vehicle concept, which was also created around a three-box sedan shape and also based on a Mercedes platform, GL-Class in that case. It did not yield a production version, but maybe the Vision Ultimate Luxury will.
