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.

Race recap: 2016 Belgian Grand Prix is a dozen angry laps

The calm of the Formula One summer break ended with the tumult of the Belgian Grand Prix. The first two days included unusual tire pressures and grid penalties; Mercedes-AMG Petronas' Lewis Hamilton started 21st because of a 55-place grid penalty for engine and gearbox changes, McLaren's Fernando Alonso started 22nd due to a 60-place penalty for the same offenses. The bedlam rolled right into what was effectively an 11-or 12-lap race. Mercedes driver Nico Rosberg took off from pole and the cameras barely bothered with him until he took the checkered flag 44 laps later. Red Bull's Max Verstappen bogged from second on the grid, got swallowed by Ferrari's Sebastian Vettel and Kimi Raikkonen on the way to Turn 1, then attempted to recover by sticking his Red Bull's nose between Raikkonen's sidepod and the apex at the first corner. Vettel, who didn't see Verstappen, turned into La Source leaving only enough room for Raikkonen. Three cars don't fit in a space for two cars. Vettel spun, Raikkonen and Verstappen clobbered one another and all three drivers had to pit for repairs. Force India's Nico Hulkenberg zig-zagged his way into second ahead of Red Bull's Daniel Ricciardo, Williams' Valtteri Bottas, and Sergio Perez in the second Force India. On Lap 6 Kevin Magnussen lost his Renault at Raidillon at the top of Eau Rouge and flew backward into an enormous crash. Magnussen escaped with just a cut ankle. The Safety Car paraded the field for four laps before officials red flagged the race to repair the barriers. When racing resumed on Lap 10, Rosberg led Ricciardo, Hulkenberg, Alonso, and Hamilton. Ricciardo stayed ahead of Hamilton to keep second place at the end of the race, Hamilton easily got around Alonso and Hulkenberg to lock up third. Hulkenberg – who'd given up second to Ricciardo by pitting during the Safety Car period – earned another career-best fourth position ahead of teammate Perez in fifth, followed by Vettel and Alonso on recovery drives, Bottas, Raikkonen, and Felipe Massa taking 10th in the second Williams. Rosberg reignited his Driver's Championship charge with the victory, closing to nine points of leader Hamilton. We could argue that Hamilton had an equally good day by driving from 21st to third, limiting his loss to only 10 points. About that Verstappen, though... We've seen far more experienced drivers attempt the same move Verstappen made into Turn 1 – Raikkonen on Bottas in Russia in 2015, for instance.

Daimler cutting Mercedes and Smart prices by 18% in Switzerland

Automakers including Daimler and PSA are now offering substantial discounts in Switzerland to make it more affordable for Swiss customers to buy their cars, according to the latest from Bloomberg. The move, instituted by two of Europe's largest automakers, comes in response to the surprise decision last week by the Swiss National Bank to suddenly abandon its longstanding policy of capping trading of the Swiss Franc to 1.20 francs per euro. The policy has sent the value of the franc soaring, making imports into Switzerland less expensive while increasing the value of its exports. The discounts being offered by the automakers could therefore be viewed more as price adjustments to better match the changing currency value rather than an actual incentive. But whichever way you look at it, a new Mercedes or Smart will now cost Swiss buyers 18 percent less than the list price, while Peugeot and Citroen dealers in the Confoederatio Helvetica are chopping 1,000 francs ($1,144) off the price of a new passenger car or 1,500 francs ($1,716) for a new commercial vehicle. Conversely, high-end Swiss watchmakers like Rolex and Patek Philippe are looking at increasing their prices to keep up with the currency fluctuation, particularly in Japan, where the yen has dropped 17 percent against the franc in the past few days.
