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.

The Scaldarsi Emperor I is a Mercedes-Maybach S600 taken to 11 on the bad-taste scale

The custom car world is filled with vehicles designed by people that don't know when to quit. The Scaldarsi Emperor I, shown here in all its awful rose-gold glory, appears to have been designed by an enthusiast of the KFC Double Down. It's a hideous creation and we can't let it pass without saying so. We also can't look away. Scaldarsi's so-called "artists" have thoroughly reworked what was a perfectly wonderful Mercedes-Maybach S600. In addition to the 24-karat rose gold accents, the company has crafted a new front fascia and modified the side and rear treatments. Inside, the general S600 shape remains, but new leather and wood cover nearly every surface. Your insane imagination will not be tamed, as there are 24 colors for the leather, 24 types of animal hides, 78 types of wood, and 16 exterior body colors available. The result, at least in the publicity shots, is a mix of awkward textures and seats that look like a pile of colorful marshmallows. Those interested in purchasing an Emperor I can option custom-engraved champagne glasses, matching tote bags, and even an Emperor Edition Rolex watch. If the standard key fob is too common for your taste, they'll make you one custom. Watch out for that Scaldarsi logo, though – it looks mean enough to rip through your pocket and take a chunk out of your leg. We will give Scaldarsi credit for wisely letting Brabus handle the power. The Emperor I uses the 6.3-liter twin-turbocharged V12 from the Brabus Rocket 900. This 888-horsepower monster is a tuned version of the V12 AMG uses in the S65, SL65, and G65. The Emperor I has an estimated 0-60 mph time of just 3.7 seconds, which is quick enough to leave stoplights before anyone recognizes you behind the wheel. Scaldarsi is asking a mere $1.5 million for each of 10 examples being created. If you miss out on the Emperor I or are some kind of twisted completist that needs one of each, this just the first in a series of customs the company will offer. Next up is the Emperor II (a Mercedes-AMG S65 Coupe), which will be followed by the Emperor III (Bentley Bentayga), Emperor IV (Mercedes-AMG G65), and Emperor V (Bugatti Chiron). Lord help us all.

Mercedes CLA a sub-$30k car no more

To be honest, the sub-$30,000 Mercedes-Benz CLA was more a theoretical than a real thing. Squeaking in at $100 below that magical threshold, not counting a $925 destination charge, snagging a CLA anywhere near $30k meant exercising extreme self-control with the options catalog. Perhaps with that thinking in mind, Mercedes is set to effectively scrap the entire idea, with Cars Direct claiming the price on a new CLA is set to increase by about five percent, to $31,500. Adding 4Matic all-wheel drive brings the starting price to $33,500. Even the hot CLA45 AMG is getting a price bump, from $47,450 to $48,500. Frankly, it's impossible to miss where Mercedes is coming from with this move, if it actually happens. The CLA has been one of 2014's unmitigated success stories, selling so well that Mercedes has struggled to keep up with demand. Considering that, a modest price hike is to be expected.
