Blackwings, a G 63 gets dirty and a wave of rad-era nostalgia | Autoblog Podcast #693

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd, who has spent the past few weeks sampling a near-endless string of enthusiast vehicles. They start off discussing Cadillac's 2022 CT4-V and CT5-V Blackwing models, which Byron had the opportunity to drive at Virginia International Raceway. They follow that up with a discussion of the Mercedes-Benz AMG G 63, which Byron also drove on a track, albeit one of a very different sort. After that, some news. Greg and Byron run down the list of returning enthusiasts nameplates, including Integra, Z and Countach, and cap off by talking about what a third-generation Acura NSX might look like.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

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.

How Atlanta landed Mercedes-Benz

The first phone call came last spring. An international real estate company had a high-profile client that wanted to relocate its North American headquarters. The client, whose identity was confidential, narrowed the list of prospective sites to Texas, North Carolina and Georgia. Would Georgia officials be interested in a discussion? Behind the scenes, they worked for months to lure the company, touting lower housing prices and a relaxed pace of life. They arranged interviews with CEOs of other companies in Atlanta who could speak about the area's business climate and they augmented negotiations with key executives from a utility company and Atlanta-Hartsfield Airport. Ultimately, they were also offered a reported $40 to $50 million in tax incentives. Secrecy was vital. The intermediary and officials with the Georgia Department of Economic Development gave the project a code name that changed three times throughout the summer and fall, so that only a few people had access to the most basic information. It was called Operation Eagle. It was only in September that the Georgia officials learned the identity of the client, Mercedes-Benz, and only last week that Operation Eagle bore fruit when the company publicly announced it would relocate its North American headquarters from Montvale, NJ, to the north side of Atlanta. "They put themselves in a spot on the north side where millennials can live in the city, and people can live in the northern suburbs and raise a family," Tom Croteau, deputy commissioner of global commerce for the GDED, tells Autoblog. "And when you combine that with the business aspect of a lower-cost environment, that's what we were able to provide them, along with a long-term commitment to support them however we can." In the move, the company benefits from a location that's closer to a growing base of suppliers that work with German car companies in the Southeast, as well as closer proximity to ports in Brunswick, GA, that are some of the busiest in the country. Mercedes-Benz will bring 800 to 1,000 jobs to the area. In addition to the employment, Georgia benefits from another notch in its automotive belt. Atlanta is already home to Porsche's North American headquarters. Kia Motors has a major manufacturing facility in West Point, GA, and General Motors opened an information technology center in Atlanta two years ago that employs roughly 1,000 workers.
