Brabus to storm Geneva with 800-hp version of Mercedes SL65 AMG

At no point during our recent drive of the 2013 Mercedes-Benz SL65 AMG did we ever think, "You know, this thing sure is slow." After all, Merc's range-topping SL comes fitted with a twin-turbocharged 6.0-liter V12 capable of sending 621 horsepower and 738 pound-feet of torque to the rear wheels. But just in case you're still all "meh" about what the SL65 throws down, Brabus will gladly come to your rescue with this, the 800 Roadster.
As its name suggests, the 800 Roadster ups the V12's power figures to 800 horsepower and - wait for it - 1,047 pound-feet of torque. Don't get too excited, though - that torque number has been electronically limited to a measly 811 lb-ft since, you know, the transmission would probably explode if you tried to put the full force through it. Nevertheless, these represent increases of 79 hp and 73 lb-ft over the standard SL65, and that means the 800 Roadster can shoot to 62 miles per hour in just 3.7 seconds - two-tenths of a second quicker than the Merc its based on. More impressively, hitting 124 mph takes just under 10 seconds, and the droptop will finally top out at an electronically limited - limited! - 217 mph. Holy smokes.
To manage all of that speed, Brabus has engineered a special carbon fiber aero kit that reduces lift, and a unique control module for the SL65's active body control suspension lowers the ride height by one full inch. The 800 Roadster rides on new 20-inch wheels, and a unique limited-slip rear differential was added, featuring a 40 percent locking rate that further enhances performance when you're attempting to control the beast at its limits. Interior upgrades include new leather and alcantara surfaces throughout the cabin, including a leather-clad trunk.

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.

Mansory G63 AMG Sahara Edition substitutes performance for taste

We aren't sure if it's an unwritten rule or not, but it seems like European tuners are wholly incapable of building cars whose aesthetics don't offend people blessed with the gift of sight. Take Mansory, for example. The Swiss tuner has turned its hand to the Mercedes-Benz G-Class, a vehicle that on it's own is not exactly a visual stunner. Functional sure, but not exactly beautiful. But with Mansory wielding the design pen, the result is, well, yeah. It's not great. This is the Mansory G63 AMG Sahara Edition, and surprisingly, its camouflaged paint scheme is one of its least obnoxious qualities. But its grille, headlights, hood scoop, roof-mounted lights and rear spoiler just don't do this Mercedes any favors. And for some reason, the tuning firm has decided to put two different styles of 22-inch alloys. The driver's side isn't horrible, although we can't say the same about passenger-side hoops. The interior treatment is nothing compared to the cabin, though. Falcons. There are falcons in the headrests. No, we don't know why either. The avian theme isn't limited to the headrests, though, as Mansory has added wings to the seats, dash and door panels, all the while continuing on with camouflage color scheme on certain interior surfaces. Of course, if you can live with the design decisions, you'll be getting a ludicrously potent G-Wagen. Mansory has boosted the 5.5-liter, biturbocharged V8 to 828 horsepower while it's actually been limited to 737 pound-feet of torque. We aren't sure what the addition of 292 hp and 177 lb-ft of torque does to the G63's run to 60, although we're betting the Mansory version is a lot quick than the 5.3-second stock time.
