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.

Weekly Recap: Takeaways from the Frankfurt Motor Show

We obsessively covered the 2015 Frankfurt Motor Show, and naturally, we selected our favorites from this fall's biggest automotive event. Now that the dust has settled, we're looking ahead to what it all means. Here are three takeaways from the floor in Frankfurt. The Germans are serious about electric vehicles: It's a bit cliche to say BMW, Mercedes, and Audi have downplayed electrics in favor of other technologies, like diesels. For a time that may have been true, but those three companies, along with Porsche and Volkswagen, are emerging as leaders in EV development. That was on display in Frankfurt, when all of them revealed either all-electric or plug-in hybrid models. Gas prices are relatively low in the United States, but clearly the Germans are thinking long-term and globally. Everyone is serious about SUVs: You gotta have one, even if you're Bentley or Jaguar. It's 2015 and it's what consumers want. As Jaguar design director Ian Callum put it, "Not to be in the sector would be a little naive for the sake of purity." It's not just the flashy exotic luxury makers. Nissan showed the Gripz concept, which is rakish, radical, and meant to blend traits of SUVs and sports cars into a vehicle that really crosses over. Look for more, especially in the luxury sector, as Rolls-Royce, Lamborghini, and Aston Martin ramp up their own SUV efforts. There's no ceiling to the luxury market: Speaking of high-end cars, companies are continuing to invest in extravagant wares beyond just SUVs. Even during the recession, ultra-luxury makers remained relevant, and now they're back at full stride. In Frankfurt, that was illustrated by yet another S-Class model, the cabriolet, which will come in S550 and S63 AMG variants in the United States. Ferrari also showed off the 488 Spider, and Lamborghini opened up the Huracan LP 610-4 Spyder. Meanwhile, Bugatti's Vision Grand Turismo concept reminded enthusiasts that it's plotting life after the Veyron. European auto shows always draw the glitziest reveals from luxury makers, and this year didn't disappoint. OTHER NEWS & NOTES 2016 Honda Civic redesigned with snazzier style, turbo power The 10th-generation of the Honda Civic debuted this week at events in Los Angeles and Detroit ahead of its launch in the United States this fall as a 2016 model. Honda fortified the Civic with LED lights, an available turbo engine, and a more tech-laden cabin.

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.
