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.

Singer Porsche, Koenigsegg, NSX: Leno's life doesn't suck

Jay Leno had quite a productive trip this year during Monterey Car Week. Not only did he get to pal around with Ian Callum and check out the Pebble Beach Concours d'Elegance, but the denim-clad comedian also headed to The Quail to talk to some prominent figures in the modern sports car scene. Capping off the fun, he got to take a drive in a Mercedes-AMG GT S, too Perhaps the highlight of this show is a nearly 10-minute interview with Christian von Koenigsegg. The founder of the Swedish hypercar company digs deep into the Agera One:1's engineering details, relating interesting facts about the aerodynamics and transmission. In addition, Leno chats with Rob Dickenson of Singer about its newly reimagined Porsche 911 Targa, and he gets the latest scoop on the Acura NSX's progress from newly promoted Acura Vice President and General Manager Jon Ikeda. If you like hearing about the nuts and bolts of sports car development, then this video can't be missed. Of course, we were there at Monterey, too, and we pointed our own cameras at some of the amazing machinery, both vintage and modern, at all the various car-focused events of the week. Take a look back at some of our own cool footage in the videos below. Related Video:

Drive visits a Mercedes Pagoda collector in Bangkok

The term "icon" gets thrown around a lot, but if there was ever an automobile that deserved the honorific, certainly the Mercedes SL is one of them. Now in its sixth generation, the SL has been the prototypical German roadster since the 1950s. A sports car with that long a history will inevitably attract a great many collectors, but with values of first-generation 300 SLs and 190 SLs skyrocketing, those enthusiasts without bottomless pockets are turning in growing numbers to the second generation. Known as the Pagoda due to the design of its removable hardtop, the W113-generation SL arrived in 1963 and stayed in production until 1971. By that point Mercedes had built nearly 50,000 of them, selling over 19,000 of those in the United States alone. Through three engine variants – dubbed 230, 250 and 250 SL – and numerous body-styles, all featured an inline-six, transmitting to the road through manual or automatic transmissions with four or five gears. More of a cruiser, then, that an outright sports car, but one that warrants its place in the history of the automobile. In this latest episode, Drive travels to Bangkok to profile a local enthusiast and collector. That's a rather difficult undertaking in Thailand, where it's illegal to import old cars, but Sittisan Quan Sundaravej rises to the challenge, locating classics together with like-minded local enthusiasts. The heart of his collection, though, isn't one he acquired, but rather inherited from his late father. That's the kind of provenance you can't buy.
