2014 Mercedes-Benz B-Class ED has 87-mile range, 84 MPGe

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog. Let's say up front that the 87-mile single-charge range of the Mercedes-Benz actually stacks up nicely against its competition, since that distance puts the new model right in line with the Nissan Leaf and BMW i3 (we'll ignore the Tesla Model S for a second, here). You can find the numbers at the US Department of Energy's FuelEconomy website. As far as miles per gallon equivalent ratings, though, the Benz's steel frame makes it come up short, as it's about 1,300 pounds heavier than the carbon-fiber-body i3 and about 600 pounds heavier than the Leaf. The B-Class EV has a bigger battery than the i3 or the Leaf (36 kWh compared to 22 kWh for the i3 and 24 kWh for the Leaf) and that's one reason the car gets an 84 MPGe rating, which is about 26 percent less than the Leaf's and 32 percent less than the i3's. But at least the local utility companies will be happy. Mercedes-Benz priced the 177-horsepower B-Class ED in April at $41,450, or $100 more than the i3.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

Mercedes-Benz S500 Plug-in Hybrid ready for 'major role' in urban areas

We finally got a clear look at the Mercedes-Benz S500 Plug-in Hybrid at the Frankfurt Motor Show last fall, but it took until this week to learn what the vision (see what we did there) is that Mercedes-Benz has for the PHEV. Despite it's generous size, Mercedes thinks this is a vehicle that will work well in urban areas. Speaking to members of the media during the Detroit Auto Show, Thomas Weber, Daimler AG management board member and research and development chief for Mercedes-Benz cars, said that the S500 PHEV, "will play a major role in congested areas" and that it will offer "a lot of driving pleasure." Part of that pleasure will come from a 0-62 mile-per-hour time of around 5.5 seconds thanks to a turbocharged, 3.0-liter V6 and an 80-kilowatt electric motor. The PHEV also has a 19-mile EV range, which will put it at the bottom end of the Three-Pointed star plug-in lineup. The upcoming C-Class plug-in, for example, will likely go, "closer to 50 km [31 miles]," Weber said, according to Green Car Reports. The S500 PHEV will go on sale in Europe later this year and will come to the US in early 2015 but there is no timeline, yet, for the C-Class plug-in (and the standard gas-electric hybrid version) or the even-more-future E-Class hybrids.
