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.

Aston or Bust? Maybach's fate to be decided next month

What will become of Maybach? That question has been rattling around the halls of Daimler headquarters in Stuttgart for some time now. But all questions will be answered, and answered soon: according to reports, the German automaker is currently evaluating prototypes and propositions for its top-end marque, and will make its decision next month.
So, what are the options? On the one hand, Daimler could kill the Maybach brand altogether. It was a notion ill conceived and even more poorly executed, taking an old platform and building a new flagship atop it. In that way, it was sort of like the Chrysler Crossfire, only far more costly to both the buyer and manufacturer. On the other hand, Daimler could opt for the long-time-coming proposition of contracting the production (and possibly much of the development) of a new generation of Maybachs to Aston Martin.

Bahrain Grand Prix proves that Formula 1 finally has parity

Ferrari driver Sebastian Vettel claimed victory at the Bahrain Grand Prix 6.6 seconds in front of Mercedes-AMG's Lewis Hamilton. In so doing, Vettel vaulted into first place in the driver standings ahead of Hamilton, with two race victories to the Mercedes driver's one. The decisive moment in the race came with 16 laps remaining, as Hamilton served a 5-second penalty for holding up Red Bull's Daniel Ricciardo in the pit lane in an earlier pit stop during a safety car period. Hamilton was able to reclaim second place in front of teammate Valtteri Bottas with 10 laps remaining, and he cut Vettel's lead from 13 seconds to 6.6 seconds at the finish. Bottas went on to finish third, followed by Ferrari's Kimi Raikkonen in fourth. Ricciardo crossed the line in fifth, meaning there were three constructors in the top five places in Bahrain. Perhaps more than anything else, the 2017 season has been unpredictable and entertaining, marking a break from the last several years in F1 where one marque has been dominant. Here's hoping the rest of the year provides similar thrills and spectacle.
