Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Mercedes previews new C63 DTM racer alongside Edition 1

The new C-Class Coupe will undoubtedly be one of the main points of focus at the Mercedes-Benz pavilion in Frankfurt this year. But the Silver Star automaker will have more than just the base version to showcase. There's be the new AMG C63, and now two additional versions. First up is the Edition 1, the designation Mercedes often applies (in some markets anyway) to launch versions of exciting new models. For the C63 Coupe, the Edition 1 features a raft of upgrades, available in either standard (476 horsepower) or S (510 hp) states of tune. It's done up in one of two exterior appearance packages, in matte gray with either yellow trim or black. The Edition 1 also wears special 19-inch wheels in the front and 20-inchers at the back, ceramic brakes, enhanced aerodynamics package, more chrome and gloss-black trim, and an optimized interior with racing buckets. Alongside the Edition 1, Mercedes will also reveal the new DTM racing model in Frankfurt. And following the teaser sketch released the other day, it's giving us our first proper look at the new touring car right here. The new C63 DTM will replace the existing C-Coupe DTM (as it has been formally styled) that has represented the automaker in its local tin-top racing series since 2012 – winning seven races over the past four seasons, but not a championship yet. If looks are anything to go by, the new racing coupe could be up to the task. Special Model to Market Launch: Mercedes-AMG C 63 Coupe Edition 1: Inspired by Motorsport Affalterbach. Mercedes-AMG is bringing the C 63 Coupe Edition 1 special model to the starting line. The exclusive colour combination in designo Magno Selenite Grey with yellow film coating and black wheels with yellow painted rim flanges reflects the graphic design of the Frankfurt International Motor Show launch version of the Mercedes-AMG C 63 DTM racing coupe which will be used in the DTM next year. The special model is equipped with Performance seats and an aerodynamics package, highlighting its proximity to motorsport. The new Mercedes-AMG C 63 Coupe and C 63 S Coupe are also available as "Edition 1" special models from market launch. The extraordinary combination of exclusive design and equipment characteristics is inspired by the optical appearance of future Mercedes-AMG racing coupes which will compete in the popular DTM series in 2016. Two exterior designs address different customer wishes.
