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.

Mercedes Sprinter updated to take on Ford Transit, Ram ProMaster

By the end of this year, the Mercedes-Benz Sprinter will be the second-oldest nameplate in its segment here in the States, but with hot new competition waiting in the wings, Mercedes-Benz is giving its hauler a freshened look and more equipment to stave off rivals. The Sprinter was a pioneer in bringing Euro-style delivery vans to North America, and it's inspired others to transplant their Continental offerings, with the all-new Ford Transit and Ram Promaster models launching shortly. It will also continue to do battle with lower-cost traditional competitors like the Chevrolet Express and Ford E-Series.
The big Sprinter will thus get a new look to go with more safety features and available technology. While the information released here technically covers the Euro-spec 2013 Sprinter (which goes on sale in September), the US market is expected to get the new Sprinter for the 2014 model year with many of the same features. Some of this new technology includes a Crosswind Assist feature as standard equipment and the availability of Collision Prevention Assist and Blind Spot Assist as optional safety measures - Mercedes-Benz says that all three are firsts for any van in the world. Also added to the updated Sprinter is a new 1.8-liter supercharged gasoline (or CNG) engine producing 156 horsepower, which will complement the line of diesel engines that carry over and help make the Sprinter the first cargo van to meet the upcoming Euro VI emissions standards. Additionally, a lower ride height is said to improve fuel economy and should improve handling while aiding ingress and egress for both people and cargo.
In terms of styling, the Sprinter's new face also looks more like the current line of Mercedes-Benz passenger cars. This includes a more upright grille along with changes to the hood, headlights and bumper that lend it a closer kinship to models like the CLS-Class and the updated E-Class. The Sprinter will offer both halogen and HID headlights, while the latter will get LED running lamps and offer Highbeam Assist. The images shown here only reveal the exterior from front angles, but it looks like few, if any, changes have been made to the rear of the van. Interior upgrades include a thicker steering wheel, a new shift lever and the latest in audio, navigation and entertainment systems.

The mood at this year’s Paris Motor Show: Quiet

The Paris Motor Show, held every other year in the early fall, typically kicks off the annual cavalcade of automotive conclaves, one that traverses the globe between autumn and spring, introducing projective, conceptual and production-ready vehicle models to the international automotive press, automotive aficionados and a public hungry for news of our increasingly futuristic mobility enterprise. But this year, at the press preview days for the show, the grounds of the Porte de Versailles convention center felt a bit more sparsely populated than usual. This was not simply a subjective sensation, or one influenced by the center's atypically dispersed assemblage of seven discrete buildings, which tends to spread out the cars and the crowds. There were not only fewer new vehicles being premiered in Paris this year, there were fewer manufacturers there to display them. Major mainstream European OEM stalwarts such as Alfa Romeo, Fiat, Nissan and Volkswagen chose to sit out Paris this year, as did boutique manufacturers like Bentley, Aston Martin and Lamborghini. This is not simply based in some antipathy on the part of the German, British and Italian manufacturers toward the French market — though for a variety of historical and societal reasons that market may be more dominated by vehicles produced domestically than others. Rather, it is part of a larger trend in the industry. Last year, Mercedes-Benz announced that it would not be participating in the flagship North American International Auto Show in 2019 — and that it might not return. Other brands including Jaguar/Land Rover, Audi, Porsche, Mazda and nearly every exotic carmaker have also departed the Detroit show. Some of these brands will still appear in the city in which the show is taking place, and host an event offsite, to capitalize on the presence of a large number of reporters in attendance. And even brands that do have a presence at the show have shifted their vehicle introductions to the days before the official press opening in an attempt to stand out from the crowd. In many ways, this makes sense. With an expanding number of automakers, with diversification and niche-ification of models and with wholesale shifts that necessitate the introduction of EV or autonomous sub-brands, there is a growing sense that, with everyone shouting at the same time, no one can be heard.
