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.

2015 Spanish F1 Grand Prix makes its Deutsche mark

The first race of the European Formula One season inaugurates the second phase of the Championship. Teams overhaul their cars with the big updates they've been working on since Australia, and at the end of The Battle of Spain we find out how the positions on the field have changed. Mercedes-AMG Petronas driver Nico Rosberg brought a big update to his psychology, straight-up beating teammate Lewis Hamilton to take his first pole position of the season. Mercedes owns the front row and Ferrari maintains its status as primary challenger, Sebastian Vettel lining up in third. Williams proved it's been hitting the books to do better in class, though, Valtteri Bottas slotting into fourth. And Toro Rosso's visit to a track that rewards strong aero rewarded them with the best team grid position since the Italian Grand Prix in 2008: Carlos Sainz secured fifth, ahead of Max Verstappen in sixth. Kimi Raikkonen's bout of Saturday woes – it seems the Finn is always handicapped by lots of tiny issues – continued in Barcelona with one of his sets of prime tires getting cooked by malfunctioning tire warmers. He recovered well enough to take seventh on the grid, but he's got some strong competition ahead of him. He led three other drivers in the Continuous Issues department, Daniil Kvyat unable to wrestle his Infiniti Red Bull Racing higher than eighth, Williams driver Felipe Massa getting it wrong in Turn 3 to fall five places behind his teammate Bottas, and Daniel Ricciardo in the second Red Bull enduring another engine change and sloppy car behavior to get tenth. And while it turned out to be a steady race a little rough around the edges, the positions on the battlefield just might have changed. A little. Of the 66 laps in the race we might have seen Rosberg for three of them – maybe. The German got a smashing start, had a clear lead into Turn 1, and after that we checked in occasionally during his two pit stops and again at the checkered flag. He owned the entire weekend the way we're used to seeing his teammate do, and the cameras left him alone to run his race. No one got within seven seconds of him during the first third, and as the pit stop strategies played out that cushion grew. He finished seventeen seconds ahead of Hamilton, and 45 seconds ahead of third-placed Vettel. Hamilton, on the back foot all three days, stumbled out of the gate.

Infiniti shows Q30 interior ahead of Frankfurt debut

Infiniti is supposed to debut the all-new Q30 hatchback at the 2015 Frankfurt Motor Show, but as the show is still a couple of weeks away and the company has elected to release yet another image, we aren't sure there'll be all that much to see come Sept. 15. With that in mind, then, we give you the first images of the entry-level hatch's cabin, and they're, um, wow. We knew the Q30 had a lot in common with the Mercedes-Benz A-Class but as these images show, this is far more than a common platform. The steering wheel, instrument cluster, switchgear, and shifter are direct from the Mercedes parts bin. From the looks of the images, the Q30 will even have a Mercedes-style key. This might not garner much attention in the budget ranks – take the Scion iA and Mazda2, for example – but this degree of parts sharing in the premium market is sure to raise some eyebrows. It's also a rather bewildering move for Infiniti. The company is, in effect, selling a Mercedes-Benz to any new customers it attracts. That'll certainly make a Q50 a hard sell when it comes time for an upgrade. Now, in Infiniti's defense, there are some differences in the layout here. The triple nozzle-style HVAC vents have been replaced with a more conventional pair of outlets, and the instrument cluster hood extends over the built-in navigation screen. That design decision, in particular, will certainly appeal to critics of the tacked-on-tablet look offered by Mercedes. The analog buttons for the multimedia system have also been tweaked, with the result looking far cleaner than the mess of buttons offered on Mercedes' products (we wouldn't be shocked to see this layout arrive on a facelifted A-, CLA-, or GLA-Class in the near future, though). Beyond those changes, though, there are multiple Mercedes design hallmarks here, including the location of the controls for the seat adjustments. You can check out the Q30's cabin in both right- and left-hand drive varieties courtesy of the images above. And for comparison's sake, we also included our most recent gallery of the Mercedes-Benz GLA-Class at the bottom of the page. Have a look and be sure to scroll down for the official press release.
