Mercedes may be working on a new electric car dubbed 'Ecoluxe'

Automobile has a lengthy piece this month on how the four German mass-market luxury manufacturers each plan to go after Tesla with their own electric vehicles. It was written by Georg Kacher, the magazine's European bureau chief, and the English version came a month after he wrote the German-language original for Autobild. Tesla isn't exactly a threat to the Germans, but, according to the report, the Model S is planting the right kinds of seeds in niches that are important to the luxury players. The thinking is that - in addition to needed electric vehicles anyway for stricter US regulations - it's better to start designing the machinery now. The article posited Porsche's attack would rest on the coming Panamera platform, but a big hurdle would be battery placement. Unable to find one large space for a lithium-ion pack, engineers would instead put batteries everywhere they could, for a supposed tally of some "108 battery pouches" throughout the body. A few days after the Automobile piece, however, Porsche publicly said it had no intention of challenging the Model S, because the enthusiastic driving the brand is known for doesn't jive with useful range. In Kacher's retelling, Mercedes' plans are even more ambitious, supposedly taking aim at the Model S and the coming Model X. It would do this with an investment in excess of $2 billion in a program called "Ecoluxe" – Mercedes has no brand division akin to BMW's i and Audi's e-tron. The new brand would create a four-strong family of bespoke electric vehicles: a smaller platform with a wheelbase around 106 inches and a larger one with a wheelbase around 118 inches. In addition, the range would have "provisions for rear-wheel drive, all-wheel drive, and rear-wheel steering." The numbers are impressive: seating for seven in the larger vehicles, both longer than 16 feet, front and rear storage areas, ratings of up to 610 horsepower and production capacity of 80,000 units per year. When would we see such creatures? Perhaps as soon as 2019. We do know that if Tesla can knock the Model X over the outfield fence, automakers are going to have to do something. We don't know what the chances are that Ecoluxe is Mercedes' first move - but such a plan could help explain the weird Mercedes concept spied in October.

Mercedes-Benz EQC vs. Jaguar I-Pace vs. Tesla Model X: How they compare on paper

The Mercedes-Benz EQ line is officially alive and kicking, with the reveal of the EQC electric crossover. It joins a segment that, while still in its infancy, seems ready to take off. Mercedes lists as the EQC's competitors the Jaguar I-Pace, The Audi E-Tron Quattro and the BMW iX3. While we've seen all of these, at least in concept or pre-production form, only one — the Jag — has actually been launched in production form. We've seen a concept and subsequent spy shots of the iX3, and the Audi EV will get its official specs publicized later this month. One electric SUV Mercedes didn't specifically call out was the Tesla Model X. As such, we've decided to compare on paper the Mercedes-Benz EQC 400, the Jaguar I-Pace S and the Tesla Model X 75D: All three are dual-motor EVs, though the Tesla is the longest and tallest. The EQC has the most power, but it and the Model X's 4.9-second 0-60 times fall short of the I-Pace. It also has the lowest top speed and electric driving range. (Mercedes sent us an updated range figure, but it's using the generous and largely outdated NEDC cycle; we're still waiting on an EPA rating.) We'll be interested to see how much the Mercedes weighs. Mercedes hasn't divulged the price of the EQC yet, but we imagine it'll fall pretty near to the $70,000 mark. As for Audi, we'll revisit this comparison after those details are made available on September 17. If you're interested in some other EV comparisons, we have a couple others that we published to compare the I-Pace to premium Teslas, as well as against other less-expensive EVs. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools.

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.
