Nissan Micra gets fresh new look [w/video]

Nissan has given its popular Micra a substantial refresh. Completely revised fascias front and rear join small sheetmetal tweaks for an all-new look, and Nissan says buyers can expect to find a host of new technology indoors. That includes audio USB and AUX-in slots as well as a new audio and touchscreen navigation system with a larger display. Designers have also graced the model - known in some markets as the Nissan March - with a revised center console and new trim indoors. Be still our beating hearts.
Under the hood, a supercharged, direct-injection 1.2-liter gasoline three-cylinder engine continues to produce 97 horsepower, complete with a stop/start system that Nissan says helps make this powertrain one of the most efficient in the world. Buyers can also opt for diesel and non-supercharged engines if they so choose.
While periodically rumored, Nissan has no plans to bring the model to North America, but with sales in 56 nations and assembly in four different countries, the little Micra remains a big deal worldwide. You can check out an official video and press release below for more information.

Nissan to run two GT-R GT3 cars in 2015 Pirelli World Challenge series

Nissan will be lining up two FIA GT3-spec GT-Rs on the start line of the 2015 Pirelli World Challenge at the Circuit of the Americas March 6-8. Sponsored by Always Evolving, Replay XD cameras, and Nismo, the two entrants will be driven by American GT Academy winner Bryan Heitkotter and Australian racer James Davison. AIM Motorsport, the Canadian race shop founded by Roger Rodas and Erik Davis, will handle preparation of the car. It will be the first time the GT3 GT-R has come to race in America. It will race in a highly varied field, with Audi, Ferrari, Dodge, and Aston Martin among the series runners. Check out the press release below for more details. NISSAN ANNOUNCES PARTNERSHIP WITH ALWAYS EVOLVING TO CAMPAIGN TWO NISSAN GT-R GT3 CARS FOR 2015 PIRELLI WORLD CHALLENGE - 2011 Nissan GT Academy Champion Bryan Heitkotter to pilot #05 GT-R GT3 - IndyCar, Prototype and GT racer James Davison to Campaign #33 GT-R GT3 - First U.S. Appearance of Nissan GT-R Built to FIA GT3 Specifications - Debuts in Pirelli World Challenge at Circuit of the Americas March 6-8 NASHVILLE, Tenn. 19/02/15 – Nissan Motorsports announced today a partnership with Always Evolving (AE) to campaign two GT Academy-NISMO Nissan GT-R GT3 racing cars for the 2015 Pirelli World Challenge season. Nissan GT Academy North America 2011 winner Bryan Heitkotter will drive one of the team cars, while Australian open wheel and GT star James Davison will pilot the second car. Featuring logos from the GT Academy program, the two cars will be co-sponsored by Replay XD and NISMO. AE will utilize AIM Autosport for much of the car preparation and on-track support during the season. Based in Los Angeles, the team was founded in March 2013 by friends Roger Rodas and Erik Davis as a platform combine their passion for cars and their desire to support their favorite charitable organizations. Following Rodas' tragic passing in November 2013, the team has established "Racing in Honor" as their internal mission for the 2014 season in his memory. AIM won the 2012 IMSA GTD team, driver and manufacturer championships, as well as the 2013 manufacturer title while campaigning a Ferrari. "Nissan couldn't be happier to have Always Evolving and AIM as Nissan's partners to campaign the first GT3 spec GT-Rs in the U.S. in Pirelli World Challenge," said Rick Kulach, Nissan North America Motorsports Manager.

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.
