Mercedes-Maybach Concept VS Bmw 8 Series Concept

BMW:

 When the E24 BMW 6-series expired with the ’80s, the company decided it was time to take its big coupe upmarket, replacing the 6 with an 8 based on the 7-series sedan. Built to impress, the 8-series was originally offered only with a V-12. It was also priced so high that many 6-series customers couldn’t or wouldn’t make the leap. BMW’s 8-series output totaled less than a third of 6-series production, and the company pulled the plug in 1999, eventually relaunching the 6 in 2003. But now BMW is nudging its big two-door upmarket again. 

 This next-generation 8 will be more modestly cylindered than BMW’s first: There will be an 840i with a turbocharged 3.0-liter inline-six and an 850i powered by a twin-turbo 4.4-liter V-8—though even the six, which makes up to 335 horsepower in today’s BMWs, will surpass the output of the original 850i’s 12-cylinder. While it must be tempting for BMW to go after the Mercedes-Benz S65, we expect the minuscule take rate of 12-cylinder S-classes will keep BMW from bothering. And we expect the 8’s prestigious positioning to preclude the offering of a hybrid model. Europe will get a diesel, but we won’t. ZF’s eight-speed automatic will be the only transmission choice, and all 8s but the base six-cylinder cars will be all-wheel drive.

Mercedes-Maybach:

 After fizzling out ignominiously a few years ago as a stand-alone Rolls-Royce and Bentley competitor, Maybach is resurgent as a sub-brand for Mercedes-Benz. It’s selling stretched S-class sedans under the Mercedes-Maybach badge in considerable numbers, including many V-12s in North America and those plus lesser-engined models in China. Now it’s launching a stunning convertible at the Pebble Beach Concours d’Elegance: Meet the Vision Mercedes-Maybach 6 cabriolet. 

 Powered by a 738-hp fully electric powertrain, the Vision Mercedes-Maybach 6 cabriolet is said to be able to travel more than 200 miles on a charge. A quick-charging system can add 60 miles of range in five minutes, the company said. There are four electric motors, one for each wheel, allowing for all-wheel drive and torque-vectoring functionality. Performance claims include zero to 60 mph in less than four seconds and a top speed governed at 155 mph.Executed in Nautical Blue Metallic and fitted with 24-inch wheels featuring 26 spokes and a rose-gold center lock, the Vision Mercedes-Maybach 6 cabriolet is the open-top version of last year’s coupe concept that took Pebble Beach by surprise. Up front, a grille with 25 vertical slats represents the new face of the brand. You will see it elsewhere in the future. 

These are two best concepts of both giants Mercedes and BMW. In my opinion both are very good, but im asking you what's your opinion on these cars?
