Mercedes-AMG developing halo car with new 12-cylinder engine

The SLS AMG was once the jewel of the Mercedes-Benz performance lineup, a commanding supercar the presence of which could be felt a football field away. The AMG GT has taken that crown with its seductive 4.0-liter V8 biturbo engine – a veritable bulldog cloaked in an alluring silhouette. But Mercedes was always clear: this was a Porsche 911-fighter. It was even called a "baby SLS." Now it appears in the world of three-starred performance halo-cars, Mercedes may be playing its own Game of Thrones. To be clear, the GT will remain top dog for some time to come, and that lineup "will expand," we're told. A Black Series is still at least a year or more away, and we could see another model in the AMG GT family beyond that. But a recent conversation with a Mercedes-AMG product planner in Austria revealed that a new halo car is in the works, one that will slot above the GT. It will likely draw power from a new 12-cylinder that's now in development, one that will be mated to an electric motor and battery pack. This ultra-hybrid setup could boast the greatest performance of any Mercedes yet. Crucially, it will have better fuel economy, good enough to justify its existence in an increasingly stringent regulatory environment. As for the new 4.0-liter V-8 in the AMG GT, you can expect to see a lot more of it, starting with the E63 AMG, sometime after the next Mercedes-Benz E-Class launches next year. Related Video:

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.

Mercedes-Benz S63 AMG officially teased in mini video

The followup to the Mercedes-Benz S550, the S63 AMG, will sport a biturbocharged V8 that will likely turn out around 550 horsepower. The new engine is probably the 5.5-liter, biturbocharged V-8 that's been popping up in everything from the ML63 to the E63 AMG. The front fascia is more aggressive, which shouldn't come as a surprise, while a meaty exhaust setup can be found out back.
We managed to pick all that up from a short, 17-second video posted by MB. The original video that unveiled the S63 AMG has since been pulled down, making this YouTube clip the best look we now have at the new super sedan, at least until the Germans give up the goods for real.
Be sure to check out the video below, along with our original posting on the S63 AMG.
