Mercedes-Benz previews its curvy sports-car and design future

Suggesting creases are passe for automotive design, Mercedes showed off ideas for its future styling directions this week at a forum in Germany, including previews of upcoming sports cars and sedans. We see images of a curvy sports car study (the silver car) with huge wheel arches flared out almost like pontoons. There's also what appears to be a rear-engine hypercar (white car); we've been reading reports about it for months. Additionally, there's a red sporty saloon, as Mercedes calls it, also among the photos. It features prominent rounded fenders and a bold horizontal grille. Mercedes also previewed its upcoming A-Class, in what it calls the Aesthetics A sculpture, which looks like a car covered in a red sheet. Though Mercedes says this is its next step to a purer design, creases and strong lines are still evident on the sides. 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.

2021 Mercedes-Maybach GLS 600 is business class without the jet lag

Mercedes-AMG demonstrated how sporty a mammoth SUV can be by unveiling the 2021 GLS 63 S at the 2019 Los Angeles Auto Show. Across the Pacific, at the Guangzhou auto show in China, Mercedes-Maybach revealed another GLS variant that puts an unabashed focus on comfort. The 2021 GLS 600 ends years of rumors by finally taking Maybach into the SUV segment. (If you don't count the limited-edition G 650 Landaulet). It's not a standalone model developed from the ground up, and it's in no way related to the electric Vision Mercedes-Maybach Ultimate Luxury concept introduced in 2018. It's a second-generation GLS dressed up in a Hugo Boss suit. Stylists spruced up the front end with Maybach's chromed waterfall grille and mesh inserts in the lower part of the bumper. An abundance of chrome trim (including big slabs of it in on the B-pillars) and Maybach emblems on the D-pillars further set the SUV apart from its non-Maybach-badged sibling. Buyers can order a two-tone paint job at an extra cost. 6.8-foot-long running boards automatically extend from under the body about a second after one of the passengers opens a door. Designers took advantage of the cavernous interior to replace the second- and third-row seats with a pair of business class-like chairs that offer heated, ventilated, massaging and reclining functions. Maybach developed the GLS with chauffeur-driven buyers in mind, so the passengers traveling in the back benefit from their own infotainment system with wireless headphones, folding tablets, wireless device chargers, plus heated and cooled cupholders. Alternatively, buyers can order the GLS as a five-seater with a three-person rear bench. The GLS 600 receives the twin-turbocharged, 4.0-liter V8 engine that's omnipresent in the Mercedes range. It delivers 550 horsepower from 6,000 to 6,500 rpm and 538 pound-feet of torque between 2,500 and 5,000 rpm in this application, and it spins the four wheels via a nine-speed automatic transmission and 4Matic all-wheel drive. Mercedes pegs its zero-to-60-mph time at 4.8 seconds. The standard 48-volt mild hybrid system briefly gives the GLS 600 an additional 21 horsepower and 184 pound-feet of torque. It also sends the kinetic energy it recuperates to the battery pack while braking or coasting, and powers a technology named E-Active Body Control which scans the road ahead and adjusts the suspension as needed if it detects a pothole, a bump or another obstacle.
