Is 120 miles just about perfect for EV range?

When it comes to battery-electric vehicles, our friend Brad Berman over at Plug In Cars says 40 miles makes all the difference in the world. That's the approximate difference in single-charge range between the battery-electric version of the Toyota RAV4 and the Nissan Leaf. It's also the difference between the appearance or disappearance of range anxiety. The 50-percent battery increase has zapped any lingering range anxiety, Berman writes. The RAV4 EV possesses a 40-kilowatt-hour pack, compared to the 24-kWh pack in the Leaf. After factoring in differences in size, weight and other issues, that means the compact SUV gets about 120 miles on a single charge in realistic driving conditions, compared to about 80 miles in the Leaf. "The 50 percent increase in battery size from Leaf to RAV has zapped any lingering range anxiety," Berman writes. His observations further feed the notion that drivers need substantial backup juice in order to feel comfortable driving EVs. Late last year, the Union of Concerned Scientists (UCS), along with the Consumers Union estimated that about 42 percent of US households could drive plug-in vehicles with "little or no change" in their driving habits, and that almost 70 percent of US commuters drive fewer than 60 miles per weekday. That would imply that a substantial swath of the country should be comfortable using a car like the Leaf as their daily driver - with first-quarter Leaf sales jumping 46 percent from a year before, more Americans certainly are. Still, the implication here is that EV sales will continue to be on the margins until an automaker steps up battery capabilities to 120 or so miles while keeping the price in the $30,000 range. Think that's a reasonable goal to shoot for?

Nissan wants French State out of its alliance with Renault

While it's called the Renault-Nissan Alliance, the French side actually throws around a lot of weight in the relationship, and the government there is the largest shareholder. Meanwhile, the Japanese company generates about two-thirds of the sales. As leader of both automakers, Carlos Ghosn is reportedly now working to put more control into the Nissan side, according to insiders speaking to Reuters. The French State is expected to fight hard against losing sway. The government in France prompted Ghosn's distrust after buying up 19.7 percent of Renault's stock, from a previous 15 percent. Officials snubbed the CEO by giving him just a few hours notice, according to Reuters. Now, the boss is looking for ways to mitigate state control, but to make this plan happen Ghosn needs formal approval from the Renault board. If successful, the proposed plan would overhaul the close partnership between the automakers. Whereas the French side currently has the final say in decisions, this move would grant both of them equal power. In addition, Nissan would become the largest owner of Renault, but the French wouldn't have the same control over its Japanese ally. The French government isn't ready to just hand over power to Ghosn, though, because it reportedly wants to protect jobs in the country. The Alliance "must not be destabilized by governance changes or adjustments that could also lead to conflicts of interest," Economy Minister Emmanuel Macron said to Reuters. Clearly, this fight is just beginning. Related Video:

Nissan EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.
