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.

European jury picks finalists for 2015 Car of the Year

There are countless Car of the Year awards handed out each year, and naturally, Europe has its own way of doing things. Every year, a panel of jurists representing seven publications in seven different languages and seven different countries get together to name their joint Car of the Year. The panel released a list of 32 candidates back in July, and it has now whittled that list down to seven nominees. The list consists of the BMW 2 Series Active Tourer, the Citroen C4 Cactus (shown), the Ford Mondeo, the Mercedes-Benz C-Class, the Nissan Qashqai, the Renault Twingo and the Volkswagen Passat. Of those seven, only two are available in the US – those being the Mondeo (sold Stateside as the Fusion) and the C-Class. The Passat is an entirely different model in North America, the Qashqai isn't offered here, Citroen and Renault don't even participate in our market and the BMW 2 Series is represented here only by the completely different coupe and convertible. Expect the one and only recipient of the 2015 Car of the Year award to be announced at the Geneva Motor Show this coming March, and while you're waiting, you can place your guesses for the eventual winner in Comments.

Apple lends prestige to a new Mercedes-Benz music system

Not often does Apple offer its name to products or technologies that emerge from beyond the walls of Fortress Cupertino. Could a partnership with Mercedes-Benz signal the start of something new? Mercedes’ new audio system unveiled this past weekend centers on the integration of Apple MusicÂ’s Spatial Audio with Dolby Atmos surround — a music enhancement generally heard in headphone-listening environments — in selected (and optional) Burmester audio systems. Plans are to offer the components initially in the Mercedes-Maybach S-Class, the S-Class as well as the EQE, EQE SUV, EQS and EQS SUV. No prices for the options were announced. Also partnering in the project is the Universal Music Group, one of the worldÂ’s leading music publishers. According to Mercedes, the Dolby tech “empowers musicians and audio engineers to place discrete audio elements or objects in a three-dimensional sound field, which goes beyond the capabilities of standard stereo productions. The system adapts to any playback environment, meaning fans can listen to music with unparalleled clarity that matches the artist's original vision in the studio.” We would expect no less from 31 speakers in a Maybach, powered by a pair of amps churning out 1,750 watts. Imagine Keith Richards cranking guitar through 31 speakers in an enclosed car cockpit. Almost three out of four music consumers say that they listen mostly in a car, says Mercedes Chairman Ola Kallenius. ”Through this exceptional partnership, we are giving our customers the extraordinary in-car audio experience they expect from Mercedes-Benz,” he said. “Both Apple and UMG share our vision and values and, together with Dolby, we will create a seamless and unique experience for our customers." Partnerships between automakers and audio companies have become common in recent years, and there have been mixed results from systems attempting to create a "surround sound" experience that goes beyond stereo. Bose put its systems into General Motors cars decades ago, and others followed, including Bowers & Wilkins, JBL and even the legendary McIntosh. Most recently, famed Italian speaker designer Sonon faber found a home in Maserati's new Grecale, and British speaker maker KEF is working with Lotus.
