2015 Japanese Grand Prix is a little Mercedes, a lot of zen

Just one week on from the issues in Singapore Mercedes-AMG Petronas appeared to have solved its clamp problems and everything else. Daniil Kvyat at Infiniti Red Bull Racing took the two Free Practice scalps on Friday, but when it came time for qualifying the front of the grid looked really familiar: Mercedes' Nico Rosberg took his second pole position of the season, Lewis Hamilton next to him in second. Kvyat had a hand in that, too, the Russian getting into a big accident in Q3 when he put two wheels on the grass heading into the hairpin and veered into the tire wall so hard that he flipped. That ended qualifying before a number of drivers had a chance to improve their times, Hamilton among them. That's how Valtteri Bottas got in third for Willliams ahead of Sebastian Vettel fourth for Ferrari. Felipe Massa had the second Williams in fifth, ahead of Kimi Raikkonen in the second Ferrari. Daniel Ricciardo lined up sixth for Infiniti Red Bull Racing, a team we're going to have to enjoy watching for the rest of the season since it might not exist come 2016. Romain Grosjean gave Lotus some good news by getting into eighth, the team so strapped for cash that it couldn't get into its hospitality area, so it held press conferences outside and ate at Bernie Ecclestone's Paddock Club. Sergio Perez took ninth for Sahara Force India, and Kvyat slotted into tenth after not setting a time. The Russsian's race would begin from the pit lane once his mechanics rebuilt his car. It wouldn't be a Formula One start lately without someone at the front having clutch problems. This time it was pole man Rosberg, whose power unit got too hot and put him a few horsepower down on Hamilton through Turns 1 and 2. That's half of how Hamilton took the lead from the lights going out, and the Brit kept it throughout the race. Rosberg, however, said his race was lost when Hamilton pushed him wide through Turn 2, a move Hamilton defended. Rosberg finished almost 19 seconds behind his teammate, a gap that probably isn't fully explained by that opening incident. Hamilton's race was so uneventful that we almost never saw him on camera – that is, we saw him so much less than we usually see him when he's out in front and unpressured that Nikki Lauda said he'd ask Ecclestone why the cameras avoided him. The conspiracy theory holds that FOM was punishing Mercedes for not supplying Red Bull with engines next year.

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.

Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.
