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.

Brabus rockets the Mercedes S65 to 900 horsepower

Some people you just can't please. They take a look at a vehicle with 621 horsepower and 738 pound-feet of torque on tap – one of the most powerful cars money can buy – and say that's still not enough. Fortunately there are companies like Brabus that cater to just such individuals. The Mercedes tuner extraordinaire brought the Rocket 900 to the Geneva Motor Show this year. It's based on the S65 AMG – yeah, the one with the twin-turbo V12 – but takes it a step or ten further. For starters, Brabus has bored the engine out to 6.3 liters and hooked up new turbochargers, exhaust, intake and more – cranking output up to 887 hp and a mind-bending 1,106 lb-ft of torque. Of course it didn't stop there, revising everything from the limited slip differential and air suspension to aero kit and interior. The result? Try 0-62 in 3.7 seconds, a 217-mile-per-hour top speed and a price tag approaching $400,000.

Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.
