2019 BMW M850i xDrive: How it compares on paper with other GT coupes

Although the hot new vehicles for the rich seem to mainly comprise SUVs and supercars, the neglected luxury GT coupe segment is starting to see some life again. The latest to add a spark to this set is the 2019 BMW M850i xDrive. It goes on sale later this year, and revives the 8 Series that's been dead since the 1990s. The first version available to Americans will be one with a twin-turbo 4.4-liter V8, with other versions likely following. Before it launches, we wanted to get a lay of the grand-touring land and see how the new BMW stacks up to the competition in performance, practicality and price. While some of these models have higher-performance or more-affordable iterations, we picked the versions that would be the closest match to this 8 Series model. They include the 2019 Lexus LC 500, 2018 Mercedes-Benz SL 550, 2018 Mercedes-Benz S 560 Coupe and the 2018 Maserati GranTurismo. We will also provide some short summaries on our experiences with these cars, but to get a full picture of each model, be sure to check out their full reviews. And if you want to compare any of these cars with models you don't see here, be sure to try out our car comparison tool. Engines, transmissions and performance On paper, the BMW M850i xDrive is clearly the performer of the group. It has the most power and torque at 523 horsepower and 553 pound-feet. Coupled with all-wheel-drive and an eight-speed automatic, the car is able to overcome its relatively portly 4,478-pound curb weight to hit 60 mph in a scant 3.6 seconds. That's more than half a second quicker than the lightest car in the group, the Mercedes-Benz SL550, which weighs 4,012 pounds. The other three vehicles are in the low- to mid-4-second range to 60 mph. Though the Maserati is the slowest to 60 mph, it does boast the highest top speed of 186 mph. The M850i and SL 550 are electronically limited to 155 mph, while the Lexus is limited to 168 mph. The Mercedes S 560 has the lowest top speed at an electronically limited 130 mph.

The BMW and Mercedes resort to forced induction, whereas the Lexus and Maserati choose to stay naturally aspirated. This is likely why the Germans break 500 pound-feet of torque, while the others don't make it to 400. Also interesting is the spread of gear quantity. The Maserati has just six ratios to choose from, and the Lexus has a whopping 10.

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.

The most or nothing: Mercedes-Maybach S650 Cabriolet pushes the luxury limits

After the introduction of the Mercedes-AMG GT Roadster at the Paris Motor Show this fall, we informed you that Mercedes-Benz has a convertible conundrum, a surplus of drop-tops that seemingly threatens to self-cannibalize within the brand's ever-proliferating lineup. Benz's head of design, Gorden Wagener, who spends much of his time in Southern California, argues it's not a problem: Each convertible, in its ideal construction, would intrinsically vanquish any issues. "The bad is the enemy of the good," he said, not exactly quoting Nietzsche. Now, the three-pointed star brand has upped the top-down ante, with the unveiling this week at the Los Angeles auto show of the Mercedes-Maybach S650 Cabriolet, a vehicle so opulent, it sits in price and position atop the uber-luxury brand's current top-of-the-line offering, the $247,900 Mercedes-AMG S65 Cabriolet. View 24 Photos "Mercedes-AMG is our performance brand so it's all about performance stuff," says Wagener in a one-on-one interview on the roof of a Beverly Hills mansion just before the new car is unveiled. "Of course, Maybach has power, too, but it's the ultimate in luxury. So it's more on that side. And for me in the interior, it's the haute couture of the automobile, so we tried to up that a little more with details. And on the exterior, it's a more superb appearance up front, more chrome, more rich, and of course we tried to up that branding even more. The S-Class is the best car in the world, we consider, I always thought we could raise the Mercedes brand. And it's the same with the S convertible." Why does Mercedes-Benz need a flagship atop its flagship? Because, when climbing the mountain of automotive luxury there is always the customer who, when he or she reaches the pinnacle, wants more. A car brand, especially one with deep pockets and luxurious heritage like Mercedes, can always further gild the automotive lilies, creating a step up for those for whom the brand's motto, The Best or Nothing, is a literal life credo. "It's always our job to make it better," Wagener says. "Each little detail, the wood, the wood under cover of the cabriolet, the leathers. All the super luxury details that make a luxury car into a super luxury car. The key is to make a modern luxury design and not a traditional luxury design. There is definitely a market for traditional luxury, but we always wanted to have Mercedes, Maybach in particular, as a modern luxury car.
