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.

Maserati's first electric car won't be a Tesla rival

Italian supercar makers haven't exactly embraced electric vehicles with gusto (the LaFerrari hybrid is about as close as you get), but that should change in the next few years. Ferrari's sibling brand Maserati tells Car and Driver that it's working on an electric vehicle that would be shown before 2020. And unlike other luxury car brands, Maserati doesn't plan on eating Tesla's lunch. It has to produce something "very different" to stand out, the company's Roberto Fedeli says. Think of something more like the GranTurismo coupe (see above) than yet another upscale sedan. Part of the challenge, Fedeli claims, is making a green machine that's exciting to drive. Breakneck acceleration is the only really thrilling aspect of EVs right now, he says – the sheer weight of those lithium-ion batteries dampens the enjoyment on twisty roads. A Maserati would have to be lighter on its feet. Also, the automaker will have to find a way to give its car character without a roaring gas engine under the hood. In that sense, Maserati's 2020 goal is realistic. It may not have much choice but to wait for battery technology to catch up to its ambitions.

Production Tesla Model X designed for women, looks 'better' [w/video]

A recent study found that men and women drive their electric vehicles differently. That might help explain why there is a male bias towards Tesla's electric offerings while the more practical Nissan Leaf get the attention of female drivers. Well, according to Tesla CEO Elon Musk, who spoke with investors yesterday during the company's annual shareholder meeting, the upcoming Tesla Model X could shift the paradigm of the gendered EV. "We probably got a little too guy-centric on the S. So, we're hoping to correct that with the X" – Elon Musk Musk didn't get into details, but responding to a question from the audience, Musk said that "we're certainly paying more attention to the needs of women in the Model X. ... We probably got a little too guy-centric on the S. So, we're hoping to correct that with the X." Musk also said that the "production version of the Model X actually looks different from [what we've seen before], it looks better." When we think about the design of the Model X, the first thing that comes to mind are those falcon-wing doors, which Tesla repeatedly promises are sticking around in the production version. Perhaps the feel of opening them is what he meant when he said the design is meant to appeal to women? So in the case of Model X that's just taken a bit longer than we would have liked. In particular, getting the falcon-wing door right is extremely difficult. Things that you maybe wouldn't expect are also very difficult, things like the second row seats are quite a challenge because what we're aiming for with the Model X is that when you open the falcon-wing door, you have the second row seats essentially framed and we want that to feel like a work of art. If you open up the door it should be this amazing experience. I mean, it may sound a bit silly, but it should just feel like "ahh!" [laughs] And then the seat, I mean it's just the seat but we want the seat to be like feel like a work of art like something you could have in a museum. Anyway, that's where we're going for with the Model X, and it's bloody hard. Whatever the case, Model X pre-orders are rolling in. Once the EV arrives in customer driveways some time next year (Musk said he expects volume production to kick in during the second quarter of 2015), we'll have a better idea if it's the soccer moms or the soccer dads who like the AWD-only Model X more. You can see all of Musk's remarks in the video below.
