SRT Viper dukes it out with Mercedes SLS Black Series in new Head 2 Head

In Episode 36 of Motor Trend's Head 2 Head, now that the Corvette ZR1 is no more, Jonny Lieberman has to look overseas to the Mercedes-Benz SLS AMG Black Series for a challenger with similar philosophy to the SRT Viper: long hood hiding a high-horsepower engine set way back, rear-wheel drive, tiny trunks. That puts the Viper's 8.4-liter V10 with 640 horsepower and 600 pound-feet of torque against the SLS AMG's 6.2-liter V8 with 622 hp and 468 lb-ft.
However, the congruences in philosophy and magnitude of numbers doesn't translate to the driving experiences of the two, which are literally and figuratively on different continents. Lieberman gets a handle on the two of them on Northern California roads, Randy Probst then finds out how, and how quickly, they can lap Laguna Seca.
They both get kudos for being improvements on their original sources, but only one of them can take the win. You can find out by watching the video below.

Autoblog drives to the Arctic Circle

In Which Mercedes' Sprinter Becomes A Long-Distance Sherpa
In the wintery wilds of northern Alaska, even the cute little critters want to kill you.
As I am about to nod off on my long leg flight from Minneapolis to Anchorage ahead of driving to the Arctic Circle, the friendly twenty-something Alaskan knitting furiously in the seat next to me pauses and says, "When you're driving up there, don't open your windows." In the dead of winter? I hadn't planned on cruising alfresco, but her warning to keep the glazing snugged against the weatherstripping is one I would take to heart. She continues: "If you leave 'em open, a fox is liable to jump right in. There are lots of rabid foxes up there, and they leap into your car and just Go. To. Town." And here I was, thinking that a curious bear or maybe an ill-placed moose in the road was going to be my biggest potential four-legged threat. In the wintery wilds of northern Alaska, even the cute little critters want to kill you.

Mercedes-Benz working on S-Class EV in accelerated green car lineup?

With Mercedes-Benz bringing out coupe and plug-in hybrid versions of its S-Class sedan, the German automaker just may follow through with a battery-electric variant as well. That's what the company's Uwe Ernstberger told the folks at Top Gear during the Geneva Motor Show. And while he noted the company still needs to work in a larger-than-usual battery pack and was less than specific with details, he did envision an all-electric S-Class "in the future." Of course, rumors started bubbling about an EV S-Class as far back as 2011, so we'll see. Christian Bokich, department manager for product and technology communications for Mercedes-Benz USA, would not confirm anything about an electric S-Class, but he did give AutoblogGreen an official rundown of MB's upcoming green cars in the US, starting with the launch of the all-electric B-Class ED in July of this year in the ZEV states (launch details for other states are TBA, he said). An S-Class plug-in hybrid is coming in the first half of 2015, followed by a C-Class PHEV closer towards the end of that year in the USA. There is also a C-Class four-cylinder BlueTEC coming at some point in 2016. Until we get more concrete information about the possible S-Class EV, let's review what we know about the PHEV. Last September, Mercedes-Benz started showing off the plug-in hybrid S-Class, saying that it could go as far as 19 miles on electric power alone and had a preliminary fuel efficiency rating of more than 78 miles per gallon, using the more lenient European driving cycle. Earlier this week, Mercedes showed off its S-Class Coupe. That model's US version will have a twin-turbocharged V8 that kicks in 449 horsepower, a few more than the presumptive S-Class EV will have. Ernstberger also said Mercedes would join the ranks of automakers offering autonomous driving systems and mentioned the S-Class as being at the "top of the movement." He held his tongue when asked about the possibility of an S-Class cabriolet.
