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: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

10 electric cars we’re excited are coming soon

If you were considering buying an electric vehicle a couple years ago, we wouldn't fault you for thinking your options were limited, both in terms of quantity and quality. You just might not have been able to find an electric car that would suit your needs, lifestyle or budget. With the newest generation of EVs that have launched in the past year or two, your options have changed — and improved — dramatically. If you still don't see an EV you like, just wait a little while longer. It won't take long. There are a whole lot more on the horizon, and the problem may soon be in narrowing down your options. To give you an example, here are 10 electric vehicles we're excited about that you'll be able to buy very soon, from GM, from Germany, from Japan and more. Some of these will be available by the end of the year, and all are expected to launch by the end of 2023. The Chevy trio: 2024 Blazer EV, Equinox EV and Silverado EV GM is stepping into the future with strong footing. Following high-end electric launches from GMC (Hummer EV) and Cadillac (Lyriq), Chevrolet is bringing three electric vehicles with familiar nameplates. The 2024 Chevy Blazer EV (above left) will offer a number of versions, starting with the 2LT and RS trims in the summer of 2023, followed by the 557-horsepower SS in the fall and the base 1LT in early 2024. The 2024 Chevy Equinox EV (above right) will go on sale in fall 2023 as a limited-edition model, with volume sales ramping up in 2024, with a base cost of “around $30,000.” For those who prefer a bed to a liftgate, the 2024 Chevy Silverado EV is an electric pickup that looks more like the old Chevy Avalanche than the current Silverado. The WT (work truck) trim launches in fall 2023, while the 664-horsepower RST will follow in 2024.

It should go on sale before the end of 2022. The i7 xDrive60 will be the only variant, with its two motors providing a total of 536 horsepower and 549 pound-feet of torque, and its battery expected to offer a range of about 300 miles. Just like its internal combustion counterpart, this full-size sedan wonÂ’t come cheap, with the i7 starting at $120,295. 2023 Hyundai Ioniq 6 Following the Hyundai Ioniq 5, Kia EV6 and Genesis GV60, the 2023 Hyundai Ioniq 6 will be the fourth car using Hyundai GroupÂ’s E-GMP electric car architecture.
