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.

2015 Nissan Leaf gets B mode standard, new MorningSky Blue color

The Nissan Leaf is getting a few updates for the 2015 model year, some functional, some purely aesthetic. The appearance options will be made available later than the rest, and include a new exterior color called MorningSky Blue, as well as standard 17-inch aluminum alloy wheels for the SV trim level. In terms of driving, the 2015 Leaf gets a dedicated B-mode for every trim level, including the base S car (it was formerly only available in the SV and SL levels). This provides more aggressive regenerative braking when the driver is not on the accelerator - perfect for making the most of those downhill grades. Now every Nissan Leaf includes Normal, Eco-Mode and B-Mode, regardless of trim level. SV and SL trim levels also get a couple new convenience features. For those who find it impossible to disconnect while driving, the Hands-Free Text Messaging Assistant allows them to communicate without taking their eyes off the road, taking their hands off the wheel or risking a distracted driving ticket (perhaps you might want to rethink using it, though). Additionally, SV and SL customers will Voice Destination Entry to make spontaneous rerouting to the theme park a little easier. Of course, a lot of other Nissan cars got some cool upgrades this year. The Quest, NV200 Compact Cargo and V6-powered Altima, for instance, eke out another mile per gallon highway and combined. See what's new in the Leaf and the rest of the Nissan lineup in the press release below. The 2015 Nissan Lineup: Charting the Changes Nissan's U.S. sales have significantly outperformed the industry in 2014, up 12.7 percent CYTD through June. Sales have been led by the recently redesigned Altima, Rogue and Sentra – along with other models such as LEAF (+29.4%), JUKE (+44.9%), Frontier (+22.6%) and NV200 (+439.3%), which have shown strong results month after month. This gives the Nissan lineup great momentum heading into the 2015 model year. Headlining the changes for 2015 is the upcoming launch of the all-new Nissan Murano (due in late 2014). As the halo vehicle for Nissan's expanding range of bold crossovers and SUVs, the dramatic 2015 Murano features a new V-motion front end, LED boomerang lights and a unique "floating" roof. Murano's breakthrough exterior design carries into the interior, which offers an engaging social lounge feel through features such as advanced NASA-inspired Zero Gravity front and outboard rear seating and oversized Power Panoramic Moonroof.

Nissan Leaf is now the best-selling plug-in vehicle of all time in US

Numbers don't lie. And in some instances, you can see their truth from miles away. As everyone expected, the Nissan Leaf is now officially the best-selling plug-in vehicle in the US. While the two vehicles aren't direct competitors (one's a pure EV and the other is a plug-in hybrid), they certainly dominate the plug-in vehicle sales charts. When we do a little math on those charts, we see that since the two vehicles went on sale at the end of 2010, the Volt has sold 75,231 units while the Leaf is now at 76,407, giving the Leaf a 1,176-vehicle lead. The Leaf trailed the Volt by just two units at the end of February. This is the first time the EV had held the overall lead since the end of February 2012, when it was ahead 10,847 to 9,623 and for a while there at the end of 2013, the Volt was up by around 12,000 units. Times have changed, though, and we don't expect the lead to switch back until the next-gen Volt goes on sale later this year, and even then nothing is certain. The Leaf sold 1,817 copies last month, a drop of 27.5 percent from last year. Year-to-date, the Leaf has sold 4,085 units, down 21.2 percent from the same time period in 2014. There were 639 Volts sold last month, a 56.8-percent sales decrease compared to March 2014. So far this year, Volt sales are down 48 percent. Green Chevrolet Nissan ev sales hybrid sales
