Maybach could become Mercedes-Benz sub-brand

When you're arriving in a twin-turbocharged, twelve-cylinder Maybach limo, there's no reason you should ever have to be late. Except, maybe, to make a fashionable entrance. But up at the corporate level, the entire Maybach brand is being slowed down as critical decisions about its future are being undertaken.
Last week, we reported that a decision on what path Maybach would take going forward would be due at the start of next month, but the latest reports indicate that the timeframe has been extended as further options are being considered.
The previous options under consideration were twofold: either relaunch the brand with production outsourced to Aston Martin - which suddenly finds itself with excess production capacity - or shut it down completely. And those are still two very real options. Word has it that Aston has put together four concept cars for the Daimler brass to consider, all based on the next-generation S-Class platform (and thankfully not the old one).

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 CLA45 AMG Racing is ready for a spot on the grid

Mercedes-Benz trotted out its CLA45 AMG-based racer at the 2013 Frankfurt Motor Show. We first showed you the sedan in the deluge of news and reveals that precedes most good auto shows, and were blown away by the car, formally known as the CLA45 AMG Racing Series.
We were strolling by the Mercedes stand, and figured we'd pop in and take a look at the new racer and its carbon-fiber body panels, gutted interior, and race-sourced aero parts. It's a looker, both as a road car and a track weapon. It's not clear what series the CLA45 AMG will qualify for, although it does seem like a shoe-in for the World Touring Car Championship. Let us know what you think of the CLA racer down in the comments. In the meantime, we've got a full gallery of live images up top, along with the stock images that were posted last week on the Mercedes-Benz Facebook page.
