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.

Mercedes making aggressive plans for Chinese market

Mercedes-Benz is preparing a major product offensive to counteract lagging sales in the Chinese market, aiming 20 new or updated models at the People's Republic in the next two years, according to a report by Reuters. The plan is part of MB's so-called 2020 Initiative, which will see the Stuttgart-based manufacturer dump 2 billion Euros ($2.67 billion) into its Chinese market vehicles in a bid to boost sales to 300,000 units by 2015.
Were it to succeed, China would become the largest market for the Silver Arrow, outpacing Germany and the United States. Leading the charge will be the redesigned E-Class, which is set to launch in China this week. That will quickly be followed by the S-Class, and eventually by the GLA-Class in 2014.
Mercedes has struggled in China, especially relative to its German competition, BMW and Audi. Where Mercedes saw a mere four-percent increase in 2012 sales to 206,150 units, Audi was up a staggering 32 percent, while BMW's numbers jumped 41 percent. While some voices, according to Reuters, accuse Munich and Ingolstadt of boosting their numbers through hefty incentives, the fact remains that Mercedes was just walloped by its competitors last year.

The Mercedes-Benz S-Class leads this month's list of discounts

Like last month, the biggest discounts car buyers will find on new vehicles are all applied to expensive luxury sedans. Unlike last month when there were two, there isn't a single Rolls-Royce to be found anywhere in the top five. Sorry, one-percenters. But just because the pinnacle of European luxury isn't represented doesn't mean there aren't big discounts to be found on lovely luxury sedans. In fact, this month's list is led by the 2020 Mercedes-Benz S-Class, a technological wonder that coddles its driver and passengers with all the bells and whistles the German brand has to offer. The Mercedes-Benz S-Class is offered in many shapes and sizes with several powertrain options. That means there will be a huge variance in prices across the model range, but on average, 2020 S-Class buyers are seeing $11,803 lopped off the car's $109,447 sticker price, leaving an average transaction price of $97,644. That's a savings of nearly 11%. It's worth noting that there's a new S-Class for 2021, but the 2020 edition is still a lovely machine. Up next is the Porsche Taycan, sitting in second place just like it did last month. Buyers are seeing average sticker prices of $125,736 but are paying $113,938. That's a savings of $11,798 — or about 9.4% — off the price on the window sticker. As was the case last month, we're not sure how many of the Taycan's buyers will be able to claim tax rebates due to the Taycan's status as an electric vehicle, but that could potentially represent a further cut off the car's sticker. Rounding out the top three for the month of July is the Maserati Ghibli. With an average discount of $10,161 that represents a whopping 14.3% of the car's sticker price, this Italian luxury sedan actually leads the list of vehicle discounts when ranked by percentage. And if you're a Maserati fan but the Ghibli isn't your cup of espresso, the Levante crossover and larger Quattroporte sedan are also seeing very large discounts.
