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.

Mercedes-Benz cut fleetwide emissions by 4.3 percent last year

Mercedes-Benz says it reduced its fleetwide vehicle emissions by 4.3 percent last year. Of course, the German automaker has another 29 percent to go to meet the European Commission's 2020 mandate. But who's counting? Mercedes' luxury and sports car bent has made it a relative laggard when it comes to increasing fleetwide fuel-efficiency, but the company did reduce emissions from 140 grams of CO2 per kilometer to 134 last year. The company's fleetwide fuel efficiency (calculated using the lenient European standard) was 5.4 liters per 100 kilometers, which equals about 44 miles per gallon and represents a 25-percent jump since 2007. Benz has come a long way from its gas-swilling V8 tanks of the 1970s. In fact, the company said its top performer, in the fuel-efficiency sense, was the diesel-powered B180 CDI BlueEfficiency Edition, which consumes 3.8 liters per 100 kilometers. That equals about 62 mpg (again, on the lenient scale). The company got some additional good press by revealing that Winfried Kretschmann, Minister-President of the German State of Baden-Wurttemberg, drives a Mercedes-Benz S300 BlueTEC Hybrid. Not exactly a Nissan Leaf, mind you, but it's a start, as is the company's efforts to bring its fleetwide emissions ever closer to the 95g CO2/km level that the EC is mandating by 2020. Take a look at Mercedes-Benz's press release below. Minister-President of the German State of Baden-Wurttemberg, Winfried Kretschmann (left), with Prof. Dr. Thomas Weber (right) and a Mercedes-Benz S-Class S 300 BlueTEC HYBRID Fleet fuel consumption for Mercedes-Benz Cars falls to 134 g CO2/km: Top efficiency figures in all vehicle classes Stuttgart, Apr 08, 2014 Benefit for the environment and customers: In almost all vehicle classes, Mercedes-Benz offers the most efficient vehicle in the competitive lineup. Moreover, in 2013 the company was able to reduce the fuel consumption and CO2 emissions[1] of the Mercedes-Benz Cars EU new vehicle fleet by a further six grams, to 134 g CO2/km. This means that in 2013, the average fleet consumption was 5.4 litres/100 km – a reduction by 24.7 percent since 2007. At present the company offers more than 50 models emitting less than 120 g CO2/km and 71 models emitting less than 130 g CO2/km. Customers can find vehicles in the Mercedes-Benz model range that consume considerably less fuel than competing models. "With our model initiative we want to be the leading premium manufacturer by 2020 again, says Prof.

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.
