Chevy Volt, Nissan Leaf sales show big drops in September

As most readers likely know, it's not just lower gas prices that are affecting plug-in vehicle sales. The two long-time sales leaders in the US - the Nissan Leaf and the Chevy Volt - are getting long in the tooth. First introduced in late 2010, the vehicles have been updated here and there since then, but recent sales figures have been lagging behind where they were in 2014. This trend continued in September, with sales of both vehicles down in a big way compared to last year. Sales of Nissan Leaf totaled 1,247 for the month of September. This is down a whopping 56.7 percent from September 2014, but thankfully the year-to-date sales are not quite as negative. So far this year, Nissan has sold 13,630 Leafs, which is "just" 37.5 percent lower tan the YTD total at this point in 2014 (21,822). This decrease swims against the overall direction of Nissan's September sales, which were up 18 percent over last year and set a new September record. The Volt sold 949 units last month, down 31.9 percent from last September. Year to date, the Volt has sold 9,264 units, which is 36.3 percent lower than the number of Volts that were sold in the first nine months of 2014 (14,540). This downward trend might be coming to an end soon. The new Chevy Volt will go on sale in 11 US states later this fall, and the 2017 model will be available nationwide next spring. An updated Leaf for the 2016 model year also offers more miles – 107, vs 84 in the 2015 version – so potential customers who have been waiting for the latest and greatest will soon not have any excuses. We'll have our broader look at green car sales in the US up soon. Green Chevrolet Nissan Electric Hybrid ev sales hybrid sales volt

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

2016 Nissan Maxima launches production in Tennessee

The 2016 Nissan Maxima saw its big debut at the end of the brand's 90-second Super Bowl commercial this year. However, we didn't get the full details about the latest generation of the model marketed as the four-door sports car until the recent New York Auto Show. Now just a few weeks later, the sedans are rolling down the assembly line in Smyrna, TN, and they should hit the road this summer. "Today's launch of the all-new Maxima is the beginning of an exciting year for Nissan's US lineup, with new versions of the Altima, Sentra and Titan due later this year," John Martin, Nissan's senior vice president for manufacturing, supply chain management and purchasing, said in the production announcement. The sedan's revised 3.5-liter V6 is also made in Tennessee at Nissan's Decherd Powertrain Plant. The 2016 Maxima certainly looks different than other mainstream sedans with its prominent V-shaped grille, slashing headlights and floating roof. Prices start at $32,410, plus $825 for destination. For that, customers get a 300-horsepower V6 that's connected to what Nissan claims is a "performance-oriented" CVT. The latest model is also estimated to get 30 miles per gallon on the highway. NISSAN BEGINS PRODUCTION OF EIGHTH-GENERATION MAXIMA "4-DOOR SPORTS CAR" IN TENNESSEE NASHVILLE, Tenn. – Nissan's Smyrna Vehicle Assembly Plant continues its reign as the top-producing automotive plant in North America, as Gov. Bill Haslam, U.S. Senator Lamar Alexander and Tennessee Economic and Community Development Commissioner Randy Boyd joined plant employees to celebrate the start of production for the all-new 2016 Nissan Maxima. "When Nissan came to Tennessee more than 30 years ago, there were almost no auto jobs in the state," said Alexander. "Three decades later, about one-third of our manufacturing jobs are auto related, auto suppliers have located in 80 counties, and our family incomes are higher. I want to thank Nissan for providing opportunities for thousands of talented Tennesseans." The first U.S.-assembled Maxima rolled off the assembly line in Smyrna in January 2003. Since then, Nissan has produced nearly 800,000 Maxima sedans at the plant, with more than 60,000 shipped to markets worldwide. Maxima is one of six models currently built at the Smyrna plant and is assembled on the same line as the Altima midsize sedan and all-electric Nissan LEAF. Maxima's new 3.5-liter, VQ-series V6 engine is also assembled in Tennessee at Nissan's Decherd Powertrain Plant.
