Daimler wants to cut EV research spending as it preps EQ

Daimler AG is hoping that the legwork it's done preparing its EQ electric-vehicle sub-brand will allow it to slightly reduce annual spending on plug-in vehicle technology. The Mercedes-Benz parent is looking to cut electric-vehicle research-and-development spending to $13.2 billion in 2017 from about $15.4 billion this year, Bloomberg News says, citing comments Daimler CEO Dieter Zetsche made to journalists in Hamburg, Germany, this week. Daimler's annual R&D spending is up from about $11.5 billion in both 2013 and 2014. Like its competitors – for example Audi and BMW and its i sub-brand – Daimler is aiming to have as much as 25 percent of its annual vehicle sales be battery-electric within the next 10 years as part of an effort to meet stricter greenhouse-gas emissions mandates in both Europe and North America. In fact, Mercedes-Benz and Daimler's Smart division collectively have at least 10 electric-vehicle models on their slates during the next few years, though Zetsche said the German automaker will continue to find ways to make its gas- and diesel-powered vehicles more fuel-efficient as well. Daimler introduced a concept version of the Generation EQ electric SUV at the Paris Motor Show late last month. It comes powered by two electric motors and is made up of a combination of steel, aluminum, and carbon fiber, and boasts a 311-mile single-charge range (on the relatively lenient European testing standards). The SUV also has 402 horsepower, and the ability to go from 0 to 60 miles per hour in less than five seconds. Zetsche said at the time that Daimler was prepping powertrains and platforms for electric sedans, wagons, coupes, and roadsters, in addition to SUVs. Additionally, Daimler's Deutsche Accumotive unit is producing the lithium-ion battery packs for the EQs.

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-AMG planning hybrid hypercar?

It used to be that, a few overlapping two-door models aside, Mercedes-Benz and Porsche didn't really compete with one another. That's how the two ended up collaborating on projects like the Mercedes 500 E that put it on the performance sedan map without fear of stepping on each other's toes. But Porsche has grown considerably since then, challenging its Stuttgart neighbor with four-door sedans and crossovers, as well as sports coupes and convertibles. Little wonder, then, that Mercedes has hit back at Porsche with the AMG GT, and there will be many more versions to follow in 911 style. But that may not be the final salvo the Silver Star marque launches at Zuffenhausen. According to the latest bit of speculation and deduction from our friends at Motor Trend, Mercedes-AMG may be planning a hybrid hypercar of its own to take on the Porsche 918 Spyder – not to mention the McLaren P1 and LaFerrari. Solid information is sparse at this point, but after speaking to AMG chief Tobias Moers, MT speculates that the new flagship will likely be mid-engined, with a boosted version of the company's 4.0-liter twin-turbo V8 kicking out between 650 and 700 horsepower, working with a pair of electric motors at the front to deliver tenacious through-the-road all-wheel traction and a combined output in the thousand-horsepower range. There is the possibility, though, that Mercedes could go after the latest hybrid hypercars with a flagship version of its just-launched AMG GT, packing a similar powertrain setup as the ultimate evolution of the breed. Other GT versions will likely soon include a GT3 racing model, a Black Series version and a roadster – following a similar path taken not only by the 911, but also by Benz's previous halo supercars like the SLR McLaren and SLS AMG.
