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.

Cadillac Celestiq, Lyriq, Hummer, other future GM electric cars: Here's everything we saw at ‘EV Day’

WARREN, Mich. — Today, General Motors held an “EV Day” event at its Warren, Michigan, campus to present its new “Ultium” battery technology, modular electric vehicle architecture and soon-to-come electric vehicles. Unfortunately, we were forbidden from bringing cameras into the event, so while we canÂ’t show you what we saw, we can tell you more about it. While we saw the previously teased Cadillac EV (which we now know to be called the Lyriq) and the GMC Hummer pickup teased during the Super Bowl, there were a number of other future cars at the event, which GM President Mark Reuss assured us are all real vehicles in the works. The biggest surprise came at the end of the event, though, in the Cadillac Celestiq electric sedan, which Reuss described as a future flagship that would be hand-built “very locally.” It had been hiding under a dark sheet all morning, with the front and rear illuminated Cadillac emblems shining from underneath. When the wraps came off, we saw a long, white, four-seat fastback sedan. The 23-inch wheels were pushed out to the very corners of the car, giving it what appeared to be a very long wheelbase. The model on the stage had no side mirrors or visible door handles. The grille mirrored that of the Lyriq crossover next to it, with integrated lighting in lieu of the usual mesh or slats youÂ’d see in an internal combustion car. The entire roof, all the way until it tapered to the tail of the vehicle, was tinted glass. In back, vertical tail lighting ran down the C-pillar before turning rearward across the top of the trunk. Inside, everything below the beltline of the windows — essentially all but the headrests and top portion of the steering wheel, was hidden from view. Behind the Celestiq, a large digital display showed a rendering of its interior. The dash consists of a pillar-to-pillar curved LED display serving as both instrument panel and infotainment system. Protruding forward between the front seats was another touchscreen that appeared to house some more controls, with open area, probably for storage, below it. The rear seats had the same sort of touchscreen between them. Built into the back of the front seats were a pair of rear-seat entertainment screens, much like we saw in the Lyriq. The door panels blended wood, metal and animated lighting to give character and a sense of opulence. GM interior design manager Tristan Murphy was on hand to tell us a bit more about the Celestiq.

First privately owned Corvette Stingray blitzes 1/4 mile in 12.23 at 114.88 mph

Chevrolet's latest road rocket, the Corvette Stingray, is a very quick car. If one needs further proof of that, we recommend they take a look at this video from Hennessey of what is claimed to be the first privately owned C7 Corvette to make a pass down the quarter mile. Not just any quarter mile, mind, this black C7 blitzed its way down the tuner's primary testing dragstrip. The Chevrolet ran the quarter in just 12.23 seconds at 114.88 miles per hour. That is a very quick time for a stock car.
Equipped with the Z51 package and a six-speed automatic transmission, not only does the C7 run a solid time, but it does so with little to no drama. That won't last though, as Hennessey will likely return it to its owner with far more power - we just hope they show a drag run of the completed product. Take a look below to watch the C7's 12.23-second run on video.
