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.

2016 Malaysian Grand Prix recap: Surprises and missed opportunities

Mercedes-AMG Petronas pilot Lewis Hamilton drove so well in the run-up to the Malaysian Grand Prix that he said before the race, "Honestly, I don't feel anything is going to stop us." On Sunday, the Sepang race showed what it thought of plans and predictions. Heading into the right-hand Turn 1, Sebastian Vettel practically recreated the dust-up at the Belgian Grand Prix three races ago. When Mercedes' Nico Rosberg swept across from the outside line toward the apex, Red Bull's Max Verstappen had to jink right to avoid, touching Vettel's Ferrari on the inside. Vettel speared straight on and hit Rosberg. Vettel's left front suspension broke, ending his race. Rosberg spun and got moving again, but at the back of the pack. That appeared to put Hamilton on a clear run to the checkered flag. His car looked perfect, his pace was perfect, he easily kept Red Bull's Daniel Ricciardo and Verstappen behind. A result that would have seen Hamilton retake control of the Driver's Championship – at Petronas' home race – got crushed on Lap 41 when Hamilton's engine blew down the main straight. That put Ricciardo in the lead, followed closely by his teammate. Just two laps before Hamilton's exit, Ricciardo and Verstappen had battled for second place with some of the best driving we've seen all season. Ricciardo drove as if exorcising the demons of missed opportunities earlier in the year, keeping the young Dutchman behind. The two Red Bulls took the flag fifteen laps later in that order, clocking the first one-two finish for a team other than Mercedes since 2014. It's Red Bull's first one-two since Brazil 2013, when Vettel and Mark Weber took the top steps at the last race of the V8 era. Rosberg recovered to take third in spite of a ten-second penalty for an optimistic pass on Ferrari's Kimi Raikkonen. The Finn crossed the line 12 seconds later, followed by Valtteri Bottas in the Williams and Sergio Perez in the Force India. In another Belgium repeat, Fernando Alonso drove from the back of the grid to finish seventh. Nico Hulkenberg secured eighth, Jenson Button ninth for McLaren in his 300th grand prix, and rookie Jolyon Palmer scored his first point of the season for Renault in tenth. The issue to trump all others from now until next week's Japanese Grand Prix: Lewis Hamilton's terrible luck with engines. Power unit gremlins earlier this season helped drop the Brit to 43 points behind Rosberg after the Russian Grand Prix.

2016 Mercedes-Maybach S600 First Drive

Imagine the audacity: during the salad days of the early 2000s, the company that invented the automobile – already synonymous with class-leading luxury – sought to further expand its portfolio by crashing the ultraluxury party. Going up against the likes of Rolls-Royce and Bentley, Mercedes-Benz traded its unmistakable Three-Pointed Star for a Mighty Mouse-like logo, exhuming a stately, long-dead German marque originally founded in 1909. The long-wheelbase Maybach 62 listed at an epic $360,000, while later spinoffs included curiosities like the nearly $700,000 Zeppelin, and a roofless, seven-figure limousine dubbed Laundaulet. By the time the financial bubble finally burst in 2008, the brand's fate was all but sealed, with US sales dropping into the double digits. It limped along another four years, but when the nameplate finally went kerplunk, it left behind it a trail of disappointed movers, shakers, moguls and rappers. The perfect postmodern metaphor for the brand's funeral pyre? Kanye West and Jay-Z's Otis music video, in which a perfectly fine Maybach is chopped and deconstructed, flames spewing out the tailpipes as it powerslides through an empty parking lot. Meet The (Sorta) New Boss Rising from the ashes of hubris is the 2016 Mercedes-Maybach S600, a recalibrated stab at high-end luxury with a startlingly similar, yet different, approach to its forbear. Like the last go, the new sled features a significantly longer wheelbase, which stretches 8.1 inches over the standard S600. Additional sound damping helps it claim the quietest rear cabin in all of production automobiledom, and posher trim bits include a rim of wood surrounding the reclining rear seats. Among the livery-focused special features is a rearview mirror-mounted microphone to amplify the driver's voice, an available rear fridge, and an executive seat package with folding tray tables. The super high-end hallmarks are there – a twin-turbo V12 dispatching sub-5 second 0 to 60 times, a stunning 24 speaker Burmester sound system, double-M branded silver plate champagne flutes, et al. – but the hyperinflated price tag is not. Starting at $189,350, roughly half the cost of the old flagship, the new Maybach isn't even the most expensive Mercedes-Benz you can buy. That distinction goes to the S65 AMG Coupe, which empties your coffers to the tune of $230,900.
