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.

2022 Villa d'Este Concours d'Elegance Mega Gallery | The show in pictures

COMO, Italy — Held annually, the Villa d'Este Concours d'Elegance is, in many ways, Europe's version of the Pebble Beach Concours d'Elegance. It takes place in a beautiful location, and it brings together an impressive selection of rare and valuable cars. It's a real treat for the eyes, the ears, and, if you're into champagne, the palate. The 2022 edition of the show was no exception: About 50 cars were shipped to Lake Como from over a dozen countries, and it wasn't just the usual suspects. Sure, there were a lot of pre-war cars (including a couple of one-off models), but some of the icons that younger enthusiasts grew up with (like the Lamborghini Countach) were present as well. This year's event was split into eight categories: The Art Deco Era of Motor Car Design, The Supercharged Mercedes-Benz, How Grand Entrances Were Once Made, Eight Decades of Ferrari Represented in Eight Icons, "Win on Sunday, Sell on Monday," BMW's M Cars and Their Ancestors, Pioneers That Chased the Magic 300 KPH, And a design award for concept and prototypes. The jury gave the coveted "best of show" award to a 1937 Bugatti 57 S owned by Andrew Picker of Monaco, while the aforementioned classes were won by, respectively: The Bugatti 57 S, shown below, A 1936 Mercedes-Benz 540K Cabriolet, A 1956 Chrysler Boano Coupe Speciale, A 1966 Ferrari 356 P Berlinetta Speciale Tre Posti, A 1961 Porsche 356 B Carrera Abarth GTL, A 1972 BMW 3.0 CSL, A 1989 Porsche 959 Sport, And the Bugatti Bolide concept unveiled in 2020. Winning at Villa d'Este is a big deal: The cars are judged by a panel of highly experienced judges. No one gave me a scoring sheet, presumably out of fear that I'd award points to the late-model Fiat 600 lurking in the parking lot, but several cars that didn't win an award caught my eye. One is a 1934 Bugatti Type 59 Sports, a grand-prix racer that was once owned by King Leopold III of Belgium and that has never been restored — its patina is inimitable. Another is a 1961 BMW 700 RS. One of two built (the other is in the BMW collection), it's a tiny, ultra-light roadster related to the 700 and powered by a 697-cubic-centimeter air-cooled flat-twin tuned to develop 70 horsepower. It won several hill-climb events during the 1960s, and it's one of the rarest cars ever to wear a BMW roundel. Aston Martin's freshly-restored 1979 Bulldog concept was cool to see as well; check out the cassette player integrated into the headliner!

Brabus 800 Roadster is a power-mad aristocrat

If we're being completely honest, we haven't exactly been in love with the aesthetics of the sixth-generation Mercedes-Benz SL-Class. It's mostly a front-end issue, with its glowering eagle-eye headlamps and upright, dinner-plate-sized Three-Pointed Star coming across to us as overwrought. That's particularly troublesome for a roadster whose history has of the most elegant designs of all time in its back catalog. Somehow, the new R231 generation's brash visuals seem more at home on this Brabus 800 Roadster to us.
That's probably because the high-dollar German tuner has turned up the wick on the SL's visuals even further, with carbon fiber bodywork, a more aggressive aero kit, matte hood scoop and complex two-finish wheels. It's all-the-way committed to its brashness, in other words - and justifiably so. Anything with 800 horsepower and 1,047 pound-feet of torque has earned the right to look however it wants, right?
Brabus started with the SL65 and its not-exactly-underpowered 6.0-liter twin-turbo V12, and went to town, fitting their own turbocharger and intercooler system, along with a less-restrictive exhaust system with driver-selectable sound levels and new engine electronics. The result is a 3.7-second 0-62 mph time, an electronically limited top whack of 217 mph... and one seriously compromised toupée.
