Mercedes to roll out S65 AMG Coupe in July

We're still a couple of weeks away from the public debut of the new Mercedes S63 AMG Coupe at the fast-approaching New York Auto Show, but already we're receiving word of an even more powerful version in the works. That, of course, would be the S65 AMG Coupe - the twelve-cylinder version of the latest S-Class Coupe, two-door counterpart to the S65 AMG sedan and replacement for the outgoing CL65 AMG.
Like the four-door version rolled out back in November, the S65 AMG Coupe would be distinguished from less powerful vehicles (which, lets face it, is just about everything) principally by its engine: a massive, 6.0-liter twin-turbo V12 that produces 621 horsepower, 738 pound-feet of torque and cares as much about global warming as an oil-shipping mega-tanker.
Because Merc's 4Matic all-wheel drive system can't handle that much torque, the ne plus ultra coupe would (like the S65 sedan but unlike the S63 coupe) be offered only in rear-drive form. That means it will have that much more trouble getting the power down to the road, but since the Magic Body Control suspension is similarly incompatible with 4Matic, the flagship coupe will get that trick suspension.

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.

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.
