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.

Veneno Roadster, One:1, One-77, LaFerrari, P1, Veyron headline 25-car Bonham's auction

Bonhams is holding a no-reserve auction in fall 2019 that includes some of the most valuable and sought-after supercars of the past decade. The lot of 25 beautiful collector items includes a Lamborghini Veneno Roadster, a Koenigsegg One:1, an Aston Martin One-77, a Ferrari LaFerrari, a McLaren P1, and a Bugatti Veyron. The collection, which was seized from a corrupt politician from Equatorial Guinea, is valued at roughly $13 million. If selling off future classics that are still in their infancy as collector items seems strange, it's because this is not a straightforward situation. These cars will be sold off by the State of Geneva, not a person. The collection was previously owned by the vice president of Equatorial Guinea, Teodoro Obiang, but the cars were seized when he was placed under investigation for money laundering and unfair management of public interests. These 25 cars, which were located in Geneva, were first sequestered in fall 2016. A trial court ordered them sold off, and the money earned from the sales would be invested in social programs that benefit Equatorial Guinea. And so, Equatorial Guinea is about to see an influx of cash, as every vehicle is valued in the hundreds of thousands, if not millions, of dollars. The rarest might be the Koenigsegg One:1. One of only six remaining, it has 371 miles on the dial, and is valued at roughly $1.8 million. The Lamborghini Veneno Roadster, one of nine in the world, is a close second. It has 202 miles logged, and is valued at about $5.1 million. The Aston Martin One-77 is another rare bird. It is example No. 35 of 77, holds a 7.3-liter V12 engine, and is valued at about $1.4 million. A McLaren P1, Ferrari LaFerrari, and Bugatti Veyron 16.4 round out the top of the list. The remaining cars are not fully detailed, but they include examples from Mercedes-Maybach, Bentley, Maserati and Porsche. The auction will take place on Sunday, Sept. 29, at the Bonmont Golf & Country Club near Lake Geneva. For more photos and information, visit Bonhams.

Germans, Brits and Ferrari's new V12 SUV | Autoblog Podcast #748

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. With the Detroit Auto Show now in the rearview, focus shifts to news that crept up outside of the North American spotlight. The two talk about the new Ferrari Purosangue SUV, then pivot to a discussion about the future of the Dodge Charger and Challenger based on rumors of a new assembly facility. Next, they discuss what they've been driving recently. Byron leads off with anecdotes from his trip to Spain to drive the 2023 Range Rover Sport and his weekend with the VW GTI SE. Next, Greg talks about the ups and downs of the BMW X3 M Competition and Mercedes-Benz GLE450 Coupe. After that, they spend your money; this week's is a whopper.   Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.
