Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

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.

Eight Mercedes Fuso Canter E-Cell trucks now in service

Portugal is far better known for its scenery and seascapes (not to mention some of its alcoholic beverages) than its place as a vehicle-testing center. But the European country is serving just that purpose for Daimler's Mercedes-Benz division and a new line of trucks. And they are of the battery-electric variety. Daimler has sent eight of its Mercedes-Benz Fuso Canter E-Cell battery-electric trucks for customer-trial purposes to various parts of the Western European country. And these customers include the Portuguese cities of Lisbon, Porto and Abrantes as well as delivery company Transporta. These entities will be testing trucks that have about a 60-mile single-charge range and deliver 150 horsepower. The trials for the trucks, which have 14-foot beds, will last one year. Daimler hasn't released a whole lot of details on further development or sales possibilities of the model. The hybrid version of the Fuso Canter debuted in the fall of 2009 and was under the Mitsubishi badge at the time, even though it was 85-percent owned by Daimler. That model is said to boost fuel economy relative to conventionally-powered trucks by as much as 23 percent. Take a look at Daimler's press release on the Fuso Canter E-Cell and its Portugal testing below. Zero emission and quiet as a whisper: eight new Fuso Canter E-Cell in customer trials Eight Fuso Canter E-Cell in real-life testing with customers for a year Locally emission-free and virtually noiseless Powerful, high-torque electric motor Battery capacity ensures range of more than 100 km Highlight of anniversary year for the Canter assembly plant in Tramagal, Portugal The drive system to suit: Canter Euro VI, Canter Eco Hybrid and Canter E-Cell The cleanest technology, whatever the application: Fuso is a pioneer of "green" drive systems in the commercial vehicle sector. The Daimler subsidiary in Japan is the home of Daimler Trucks' centre of competence for hybrid technology, and with this experience behind it, Fuso has also been responsible for developing the new battery-electric-powered "Zero Emission" Canter E-Cell. The first all-electric light-duty truck, produced in a small series, runs emission-free and almost silently. The Canter E-Cell for Europe is manufactured at the Tramagal plant in Portugal. Eight vehicles have now been released for customer trials.
