2015 Russian Grand Prix was full of crashes and DNFs

Mercedes-AMG Petronas non-executive chairman Niki Lauda said of Lewis Hamilton's race-day domination this year, "The guy is driving like a god." Qualifying is another story, though – teammate Nico Rosberg taking pole proved that sometimes deities have to settle for second on the grid. Williams driver Valtteri Bottas surprised himself and his team with third place, half a second behind Hamilton but 0.05 sec ahead of the first Ferrari driven by Sebastian Vettel, while a mistake on Kimi Raikkonen's final flying lap left him in fifth, 0.4 sec behind Vettel. The Sahara Force India team had a good showing, with Nico Hulkenberg qualifying sixth just ahead of teammate Sergio Perez in seventh. It's the first time they've had both drivers in the top ten on the grid since the 2014 British Grand Prix. Romain Grosjean is leaving the stormy waters of Lotus at the end of the year for the unknown waters of Haas F1, but he made the shoestring operation look really good before Renault takes over by taking eighth place on the grid. Max Verstappen qualified well again with ninth in the Toro Rosso, ahead of the first Infiniti Red Bull Racing of Daniel Ricciardo in tenth. Red Bull driver Daniil Kvyat lined up eleventh for his home grand prix, certainly a disappointment after locking up fifth place on the grid last year in a Toro Rosso. When Pirelli brought soft and supersoft compounds to Sochi, the company said it hoped this year's race would be better than last year's. We're sure this first-lap mishap isn't what they meant. Rosberg and Hamilton dragged it down to Turn 1, with Rosberg getting the inside line. Hamilton had to go wide at Turn 2 as Rosberg fought to hold position, but they left a mess in their wake: Hulkenberg spun going into Turn 2 and stopped in the middle of the track, and Marcus Ericsson in the Sauber – who'd started 16th – collided with him. Both cars were out of the race immediately, and the Safety Car came in. The Safety Car returned to the pits on Lap 3 Rosberg led the field, but just two laps later the German complained of a sticking throttle pedal. Two laps later he had to retire, unable to drive the car properly. That put Hamilton at the front, and we've seen that race a bunch of times before. He built a double-digit lead and never lost it.

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.

Recharge Wrap-up: 2015 Honda CR-Z now on sale, Daimler and Linde building hydrogen stations in Germany

The 2015 Honda CR-Z hybrid is now available at dealerships, for slightly more money. The CR-Z starts at an MSRP of $20,145 (plus $790 in destination charges), up from the $19,995 price of the 2014 model. For those who don't want to row their own gears with the six-speed manual transmission, the available CVT adds an extra $650 to the price, but also offers better fuel economy, especially in the city. The manual-equipped CR-Z gets 31 mpg city/38 highway/34 combined, while the CVT version is rated at 36/39/37 mpg. The 1.5-liter engine and electric motor provide a combined peak 130 horsepower. The manual CR-Z offers 140 pound-feet of torque, with the CVT version providing 127 pound-feet. Customers can also soup up their new CR-Z with upgrades (including a supercharger) from Honda Performance Development. Learn more in the press release below. Daimler and Linde are teaming up to build hydrogen fueling stations in Germany. The automaker and gases and engineering company, with the help of a few oil and gas companies, plan to install 13 new stations by the end of 2015. The installations precede a push by Daimler to get more fuel cell vehicles on the road. "From 2017, we are planning to bring competitively priced fuel-cell vehicles to market," says Daimler's Herbert Kohler. "So now is the time to build a nationwide fuelling infrastructure." Linde will supply the stations with fully renewable hydrogen. Read more in the press release below. In 1899, an EV set a world landspeed record, and Wired has revisited the story with a nice look back at the "La Jamais Contente" and its driver, Belgian engineer Camille Jenatzy. Jenatzy built an electric car to race in a hillclimb, which he won while clocking a top speed of 17 miles per hour (measured the old-timey way - without radar guns). Just a few weeks later, another man set a landspeed record of 32 miles per hour, beginning a back-and-forth series of setting new records. Then, on April 29, 1899, "The Red Devil," as Jenatzy became known as, surpassed 100 kph (62 mph) when his torpedo-shaped electric car set a record of 65.8 mph. It was powered by two 25-kilowatt electric motors. Read the whole story over at Wired.
