AMG-powered Aston Martins still years away

After flirting for several years, Mercedes-Benz and Aston Martin have finally tied the knot. Just don't expect to see any offspring to result from the union for at least three or four years.
This according to Auto Express, which spoke with Daimler chief Dr. Dieter Zetsche at the Frankfurt Motor Show last week. AE reports that a new range of AMG-developed turbocharged V8s, transmissions and electrical components will make their way into the successors to the current V8 Vantage and DB9, but that these models are still a few years off.
Purists might balk at the thought of a Mercedes-powered Aston holding true to the brand's heritage. But while David Brown (for whom the DB range is named) may have steered clear of shoehorning in Detroit muscle into his cars, the entirety of the company's current range is powered by engines borrowing technology from Ford, and that arrangement seems to have worked well for Aston until now. And if you're still skeptical, look no further than Pagani and its AMG-sourced engines and you should have all the proof you need that the new relationship between Daimler and Aston could be a success.

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.

Drive visits a Mercedes Pagoda collector in Bangkok

The term "icon" gets thrown around a lot, but if there was ever an automobile that deserved the honorific, certainly the Mercedes SL is one of them. Now in its sixth generation, the SL has been the prototypical German roadster since the 1950s. A sports car with that long a history will inevitably attract a great many collectors, but with values of first-generation 300 SLs and 190 SLs skyrocketing, those enthusiasts without bottomless pockets are turning in growing numbers to the second generation. Known as the Pagoda due to the design of its removable hardtop, the W113-generation SL arrived in 1963 and stayed in production until 1971. By that point Mercedes had built nearly 50,000 of them, selling over 19,000 of those in the United States alone. Through three engine variants – dubbed 230, 250 and 250 SL – and numerous body-styles, all featured an inline-six, transmitting to the road through manual or automatic transmissions with four or five gears. More of a cruiser, then, that an outright sports car, but one that warrants its place in the history of the automobile. In this latest episode, Drive travels to Bangkok to profile a local enthusiast and collector. That's a rather difficult undertaking in Thailand, where it's illegal to import old cars, but Sittisan Quan Sundaravej rises to the challenge, locating classics together with like-minded local enthusiasts. The heart of his collection, though, isn't one he acquired, but rather inherited from his late father. That's the kind of provenance you can't buy.
