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.

Race Recap: Singapore Grand Prix is about a safety car and submission

The Singapore Formula One Grand Prix is the Monaco GP of the Orient - a weekend known more for its glamour and time-slot than on-track action, with a temporary circuit that punishes every mistake, usually terminally.
Lewis Hamilton in the Mercedes-AMG Petronas got the best of Free Practice 1, opening the curtain on a possible resurgence of Silver Arrows performance. By the time qualifying was done, though, it was his teammate Nico Rosberg who lined up second on the grid, followed by Romain Grosjean with a beautiful performance in the Lotus, Mark Webber in the Infiniti Red Bull, and Hamilton all the way back in fifth. Behind them were Felipe Massa outqualifying Ferrari teammate Fernando Alonso, Jenson Button getting the McLaren into eighth, Daniel Ricciardo with another good Q3 effort to get into ninth, and the shocker of Esteban Gutiérrez getting his Sauber into the top ten for the first time this year.
At the front of the pack was Sebastian Vettel. Again. But he was only ahead of Rosberg by a single tenth of a second...

Mercedes-Benz CLA45 AMG coming to the New York Auto Show

Mercedes-Benz showed off the CLA45 AMG at a private event on the eve of the Geneva Motor Show, but was determined not to let it be photographed. We can talk about it, though - after all, a teaser image was released to promote the new Sony game Drive Club. The CLA45 AMG will use the same powertrain as the A45 AMG, which means a 2.0-liter turbocharged four-cylinder with 360 horsepower and 332 pound-feet of torque. And that means a small four-door coupe sedan with the highest horsepower-per-liter in the segment. It will shift through the same seven-speed dual-clutch transmission, should also run out of speed at 155 miles per hour and have that three-stage stability control system.
As with its hatch sibling, the CLA is already so aggressive on the outside - and the parent company so anxious not to demolish the sedan's 0.22 coefficient of drag - that not much has been done to the cranked-up CLA. Even the rather thin tires on the standard only get a little less thin on the hotter variant. Inside will be the telltale AMG signs, with lots of red detailing and that flat-bottomed wheel among the giveaways. We'll know more later this month when the wraps come off at the New York International Auto Show.
