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.

2023 Mercedes-Maybach S 680 by Virgil Abloh is maximum fashion with a V12

If the Mercedes-Maybach S 680 wasn’t already exclusive enough for you, listen up. This is the limited-edition Maybach by Virgil Abloh version of the Mercedes-Maybach S 680, and there will only be 150 of them built for the world. The vehicle is the result of a collaboration between Virgil Abloh and Mercedes chief designer Gordon Wagener. Mercedes says the design was finalized prior to AblohÂ’s passing in November 2021. In case youÂ’re unfamiliar with Abloh, know that he was many things throughout his life. HeÂ’s known best for being a fashion designer and entrepreneur, but he was also an artist, philanthropist and architect. As for the car itself, the exterior uses a two-tone paint combo that you might recall from the Project Maybach electric off-road coupe. The bottom half is meant to make you think of sand, while the top half contrasts that in a glossy Obsidian Black finish. The window frames lose their bright look and are painted black to make it as monolithic as possible from the side. Even the forged wheels are painted in the sandy hue. The same theme continues for the interior. ItÂ’s a black and tan two-tone throughout, and MercedesÂ’ Nappa Leather is used to cover surfaces. A unique Mercedes-Maybach and Virgil Abloh logo is inscribed on the center console to denote this carÂ’s special-edition status. YouÂ’ll see the same logo on rear cushions, headrests and door sills. Mercedes even went so far as to modify the infotainment system and its controls for this special edition. The “home” button gets a sandy Abloh theme, and so do the selectable apps on screen. TheyÂ’re decorated with fashion accessories, and theyÂ’re hopefully still as easy to depict and use as MercedesÂ’ standard MBUX icons. As for extras beyond the car itself, every one of these special-edition models comes with a wooden box emblazoned with the Mercedes-Maybach and Virgil Abloh logo. Inside the box, youÂ’ll find a 1:18 replica of the car, a carabiner hook and your two keys. YouÂ’re also going to get a car cover featuring the Virgil Abloh logo with the car, but this one doesnÂ’t fit in the box. If you really want to look the part next to your car, there is a whole line of clothing designed by Virgil Abloh that is launching today, too. It comprises clothing done in shades and hues similar to the car, so you can truly look the part hopping out of your Virgil Abloh Mercedes-Maybach.

Ford Mustang Shelby GT350R named Road & Track Performance Car of the Year

With a 526-horsepower, 5.2-liter V8 that roars to 8,250 rpm, it's really hard to consider the 2016 Ford Shelby Mustang GT350R an underdog in any fight. However, the Shelby held the lowest as-tested price and was only middle of the pack in terms of power in Road & Track's 2016 Performance Car of the Year challenge. The 'Stang's numbers clearly didn't tell the whole story about the potent coupe because Ford's muscle car grabbed the title in this year's test. A model needs to be new or significantly updated to be eligible for the honor, and R&T found an impressive slate of eight candidates this year. The challengers included the Bentley Continental GT3-R, Cadillac ATS-V Coupe, Chevrolet Corvette Z06, Dodge Viper ACR, Mercedes-AMG GT S, and Porsche Cayman GT4. The Ferrari 488 GTB was the most expensive of the bunch with an as-tested price of $347,942, which is five times more than the Shelby. Once the group was together, R&T hustled them over curving roads and on the National Corvette Museum Motorsports Park. There was a lot to love about the Shelby, even in this impressive crew. "With a flat-plane crank and Sport Cup 2 tires, the GT350R is a Mustang turned up to 11," editor-in-chief Larry Webster said in the announcement of the results. The GT350R joins some great company. Past winners include the Porsche 911 GT3 last year and the Corvette in 2013. For some fantastic photography and the complete appraisal of these performance machines check out R&T's website for the full story.

The article appears in the December/January issue, on newsstands November 17, and on RoadandTrack.com. "With a flat-plane crank and Sport Cup 2 tires, the GT350R is a Mustang turned up to 11," said Larry Webster, editor-in-chief of Road & Track. "Not only does the car have soul and harness so much firepower with such ease, but the real achievement here is that it's so approachable. It's a car you can't help but love." The Mustang Shelby GT350R was the winner by a runaway vote.
