2015 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.

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: Batty battery covers, Mercedes at Silvretta, new Hyundai Sonata Hybrid available in 2015

Apparently, Chevrolet Volt battery covers make suitable homes for bats. As part of an Eagle Scout project, Matthew Netherland created 30 bat houses out of scrapped Volt battery covers donated by Chevy. 22 of the bat houses will be set up near hydroelectric dams in Michigan. Each bat house will accommodate 100 bats, and divert the scrapped materials from the landfill. The battery covers also make great nesting boxes for wood ducks, which General Motors has previously set up at its Milford, Michigan Proving Ground. Last weekend was the Silvretta E-Auto Rally, which saw emissions-free vehicles cross the Montafon Mountains in Austria, including cars from Mercedes-Benz. These cars included the B-Class Electric Drive, B-Class F-Cell, SLS AMG Electric Drive and even the Smart Fortwo Electric Drive. Also on hand for the Silvretta Classic Rally was a V8-powered C111, a 1978 Mercedes-Benz 450 SLC and 300 SL Roadster. Read more in the press release, below. BMW has finalized pricing for the i8 in the US at $135,700 (plus $925 in destination charges). In addition to the base price tag, which we've known for a while, BMW Blog has the complete pricing guide with options and packages. Most of the i8 orders were the Pure Impulse World package, which includes various aesthetic upgrades. It also provides membership to the BMW i Pure Impulse Program, which allows you to "to enjoy innovative ideas and trends in a variety of areas, including home styling, culture, gourmet gastronomy, design and many more." Head over to BMW Blog for more information. The new generation of the Hyundai Sonata Hybrid will arrive later than the rest of the model lineup, confirms Car and Driver. While the gas-powered Sonatas get updated now for the 2015 model year, the Hybrid remains unchanged until late this year or early 2015, when it will arrive as a 2016 model. Hyundai is offering a 2015 Sonata Eco edition, but with 28 miles per gallon in the city and 38 mpg highway (32 combined), it's not quite as appealing as the current Sonata Hybrid's 36/40/38 figures. Read more here. In June, average US fuel economy was 25.5 miles per gallon, making it the fifth straight month above 25 mpg, according to University of Michigan. The average window sticker ratings from vehicles sold in June dropped slightly from 25.6 mpg in May. The year started at 24.9 mpg in January, and hasn't dropped below 25 mpg since.
