Mercedes-Petronas AMG W04 launched to little fanfare, lots of pressure [w/video]

No indoor cocktail hour for the launch of the W04, the newest chassis built by the Mercedes AMG Petronas Formula One team. Instead, Nico Rosberg and Lewis Hamilton spent a morning in photo and video sessions at the track in Jerez, Spain then paused a moment to introduce the car. The team will want the W04 to demonstrate the World Championship credentials of the team personnel and one of the team drivers, instead of the mostly humble performances we've seen over the past three years.
The W04 has been fitted with a new five-element front wing, pushrod front and pull-rod rear suspension, a second-generation Coanda exhaust and an "aggressively packaged" rear end. A small vanity panel, à la Infiniti Red Bull's RB9, covers the stepped nose.
Team principal Ross Brawn has called it "a clear step forward in design and detail sophistication," but as much as we truly respect Brawn's abilities and achievements, we heard him say similar things about the updated W03 last year before almost every race weekend from about mid-season. We really hope he's right this time, and so does the team's newest driver, Lewis Hamilton. We'll do our best to ignore the parallels of the Mercedes F1 team having signed a sponsorship deal with Blackberry, another company trying to find its way back to the top and still struggling, and just point you to the video below of the W04 in action.

New Forza 6 car pack adds 1,000 hp German race truck

Today, Forza Motorsport 6 continues its pattern of monthly updates with seven new cars in the Turn 10 Select Car Pack. The diverse group of cars spans nearly 60 years of motoring history with a combination three street and four track cars from Germany, Italy, the UK, and the UK. Turn 10 Studios will also release an update that brings back Monza, Catalunya, and the Circuit of the Americas tracks. The seven vehicles in the pack are the 1957 BMW Isetta 300 Export, the 1969 Ford Brawner Hawk III, the 1980 Fiat 124 Sport Spider, the 2014 Jaguar #14 Emil Frey GT3 Jaguar XK, the 2014 Chevrolet #4 ROAL Motorsport RML Cruze TC1 WTCC, the 2015 Mercedes-Benz #24 Tankpool24 Racing Truck, and the 2015 McLaren 570S Coupe. The BMW, Fiat, and McLaren all represent iconic vehicles for their respective brands. While the BMW may not be fast and the McLaren is the baby of the brand, their importance can't be overstated. It also can't be a coincidence that Fiat is releasing an all-new 124 Spider, now based on the Mazda MX-5 Miata, just as Forza is adding in a version of the original. The racecars share a similar iconic nature. The Ford Brawner Hawk III won the 1969 Indianapolis 500 with Mario Andretti at the wheel. The team behind the GT3 XK has ties with Jaguar going back decades. The Chevrolet Cruze is one of the most successful cars in the history of the World Touring Car Championship. Finally, the Mercedes-Benz racing truck was added because the developers saw them in real life and thought racing these big trucks would be cool. The car pack is available to for $7 total, or players can purchase each car individually. Related video: Related Gallery Forza 6 Car Pack Toys/Games BMW Fiat Mercedes-Benz forza car pack

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.
