Vision Mercedes-Maybach 6 Cabriolet is last year's concept with a soft top

Last year, Mercedes brought an absurd, excessive two-seat coupe to Pebble Beach called the Vision Mercedes-Maybach 6. We say absurd and excessive because it was a roughly 19-foot long coupe for just two people. It also packed a 750-horsepower electric powertrain. This year, Mercedes brought pretty much the same car, but now with a soft top and the suffix "Cabriolet." Because the Vision Mercedes-Maybach 6 Cabriolet is basically the same car as the coupe, it's also dripping with unashamed excess. It's still 19 feet long, it still carries only two people, and it still has 750 horsepower from electric motors. Mercedes claims that power will propel the car to 60 mph in under 4 seconds. Also like the coupe, it has a range of 200 miles on a charge, and with the right charger, can supposedly regain about 60 miles in 5 minutes. There are changes to the car, though. For one, it's painted a different color. Instead of the vibrant red of the coupe, the roadster is a navy blue that Mercedes says helps evoke the feeling of a yacht — more so than the size already did. It also has new wheels with a more conventional multi-spoke look. They're also have rose gold-painted accents. The change to a convertible body style alters the appearance of the Mercedes-Maybach 6 more than you'd expect, too. Now that a significant portion of the vehicle is finished in a contrasting color, the car looks a bit shorter, in a good way. It doesn't look cumbersome. The lack of a fastback also helps keep the tail from looking like it's sagging, as it does on the coupe. The interior of the Vision Mercedes-Maybach 6 Cabriolet is mostly the same as the coupe, too. It features the same white leather seats that blend into the doors and dashboard. It also has the wild wraparound display and clear center tunnel with light tubes that show the flow of electricity to the motors. Metal highlights are finished in rose gold hue, as is the stitching. The differences include more prominent shapes that imply air vents, as well as a wood floor with aluminum strips to complete the yacht feeling. Also, the buttons that dot the seats have Mercedes logos on them, and they're backlit. We also get a peak under the hood of the Mercedes-Maybach 6 Cabriolet. It opens up like pre-war cars with two panels connected by a center hinge. Because it uses compact electric motors and underfloor batteries, there's storage space under the hood.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

2015 Malaysian F1 GP springs hot, humid surprises [spoilers]

In the two weeks since Australia both Mercedes and Ferrari spoke of the improved performance from their respective cars. In Malaysia, Ferrari showed it. Lewis Hamilton still put his Mercedes-AMG Petronas on pole position, but Sebastian Vettel got within two whiskers of the Brit, lining up second just 0.074 behind. Afterward, Vettel said Ferrari could win the race if everything went well. But in qualifying we didn't know how much of Ferrari's performance was truly down to the car and how much was down to the wet weather that struck near the beginning of Q2. The rain didn't hamper Nico Rosberg's run – the German said "I just didn't drive good enough" – and he took third spot in the second Mercedes-AMG Petronas. Showing what the Infiniti Red Bull Racing chassis can do when the power unit is working properly, teammates Daniel Ricciardo and Daniil Kvyat grabbed fourth and fifth. Whippersnapper Max Verstappen, in his second race, qualified in sixth with an excellent drive through the rain; just 0.030 behind Kvyat, he said he could have got fifth if he hadn't had a running problem with his brakes. Williams head of vehicle performance Rob Smedley said he wouldn't complain about Mercedes' advantage, but Felipe Massa has spent the whole season so far banging the alarm about Ferrari's pace. He says Williams has lost its straight-line advantage, part of the reason the first Grove car is back in seventh, while Valtteri Bottas is in eighth. Between them was Romain Grosjean in the Lotus, but he got dropped two positions for a pit-lane infraction in Q2, so he'll be tenth. Ahead of him is Marcus Ericsson in the Sauber, who would lead the charge to turn in another surprise for the Swiss team. But the real surprise came from the Scuderia Ferrari, who, on a bright, sunny day proved that they don't need to add water for race-winning pace. While Hamilton got made usual awesome start at the lights, Vettel channeled that other famous German Ferrari driver and immediately cut across the track to intimidate Rosberg, maintaining his second place position into the first turn. Arguably the race-winning move came three laps later at that same turn, when Ericsson plunged in too fast and swapped ends, beaching the rear of his Sauber in the gravel trap. The safety car came out when the recovery truck emerged to retrieve the Sauber, and nearly all of the front-runners took to the pits to swap out of the medium tires. Vettel, however, didn't.
