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.

2024 NY Auto Show, the new Mercedes G and a possible Xterra revival | Autoblog Podcast #825

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd, who joins us fresh from the floor at the 2024 New York Auto Show. They start with an overview of the show and this year's big debuts, then pivot to other news for talk of the 2025 Mercedes G-Class unveiling. After that, they touch on the potential for a Toyota FJ Cruiser revival, which then leads them to an Autoblog scoop from Nissan: a new Xterra is apparently on the table. They wrap up news with an overview of this year's Easter Jeep Safari concepts. From that, it's on to what they've been driving. Greg has spent some time in the Genesis G70, while Byron shares his thoughts from his first few weeks behind the wheel of the Autoblog long-term Subaru WRX.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

Drive like a prince: Join us for a walk through Monaco's car collection

Small, crowded, and a royal pain in the trunk lid to drive into during rush hour, Monaco sounds like an improbable location for a huge car museum. And yet, this tiny city-state has been closely linked to car culture for over a century. It hosts two major racing events every year, many of its residents would qualify for a frequent shopper card if Rolls-Royce issued one, and Prince Rainier III began assembling a collection of cars in the late 1950s. He opened his collection to the public in 1993 and the museum quickly turned into a popular tourist attraction. The collection continued to grow after his death in April 2005; it moved to a new facility located right on Hercules Port in July 2022. Monaco being Monaco, you'd expect to walk into a room full of the latest, shiniest, and most powerful supercars ever to shred a tire. That's not the case: while there is no shortage of high-horsepower machines, the first cars you see after paying ˆ10 (approximately $11) to get in are pre-war models. In that era, the template for the car as we know it in 2023 hadn't been created, so an eclectic assortment of expensive and dauntingly experimental machines roamed whatever roads were available to them. One is the Leyat Helica, which was built in France in 1921 with a 1.2-liter air-cooled flat-twin sourced from the world of aviation. Fittingly, the two-cylinder spun a massive, plane-like propeller. Government vehicles get a special spot in the museum. They range from a Cadillac Series 6700 with an amusing blend of period-correct French-market yellow headlights and massive fins to a 2011 Lexus LS 600h with a custom-made transparent roof panel that was built by Belgian coachbuilder Carat Duchatelet for Prince Albert II's wedding. Here's where it all gets a little weird: you've got a 1952 Austin FX3, a Ghia-bodied 1959 Fiat 500 Jolly, a 1960 BMW Isetta, and a 1971 Lotus Seven. That has to be someone's idea of a perfect four-car garage.  One of the most significant cars in the collection lurks in the far corner of the main hall, which is located a level below the entrance. At first glance, it's a kitted-out Renault 4CV with auxiliary lights, a racing number on the front end, and a period-correct registration number issued in the Bouches-du-Rhone department of France. It doesn't look all that different than the later, unmodified 4CV parked right next to it. Here's what's special about it: this is one of the small handful of Type 1063 models built by Renault for competition.
