Mercedes to market Tesla-powered 2014 B-Class EV in U.S.

Looks like another Tesla Motors investor will be looking to cash in on their connection. Autoweek reports Mercedes-Benz will offer their B-Class in the U.S. with Tesla propulsion.
The magazine says their source at the German automaker confirms plans for a B-Class electric-only vehicle. While Tesla already provides battery packs for the battery-powered Smart ForTwo, the B-Class EV will reportedly have Tesla batteries, motor and other components. U.S. residents should be able to procure one sometime in 2014.
The same Mercedes source says plans for a hybrid B-Class have been postponed for now. Adding a range-extending, gasoline-powered engine to an electric vehicle would put the car into a different class for which rebates and incentives aren't as favorable in the States.

Mercedes-Benz releases stunning first images of 2014 S-Class

The all-new 2014 Mercedes-Benz S-Class, designated W222, is one of the most highly anticipated debuts of its model year. Every generation of the flagship sedan has broken new ground in technology and innovation for the entire industry, and the German automaker appears determined to raise the bar much further with its latest arrival as it promises to deliver "the best automobile in the world." Mercedes-Benz has just released nearly two dozen interior images of the new sedan, showing off style in design, craftsmanship in execution and pioneering advancements in technology.
Unlike all previous generations - the first S-Class officially arrived in 1972 - the 2014 model completely discards a traditional instrument cluster and replaces it with two high-resolution color displays in 8:3 format with a screen diagonal of 12.3 inches (the outgoing model's gauges were a mix of digital and analog). The left unit displays traditional analog gauges (digitally, of course) while the right unit is reserved for infotainment and comfort settings with the automaker's all-new mBrace2 - a cloud-based entertainment and information delivery system that is rolling out this year.

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.
