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.

Nismo GT-R poised to be fastest Nissan ever

For almost every year since the Nissan GT-R first debuted, Nissan has been figuring out how to cram more power under the hood or give it 911-like quickness around the Nürburgring. Looking to create a brand image for its performance arm, we already knew that a hotter, Nismo-branded GT-R was in the works, but it seems some details may have leaked regarding this new Nismo GT-R.
While little has been spoken of this Super GT-R since February, Top Gear is reporting that Nismo is planning to make improvements to the coupe's power, handing and styling - three things that we're sure few have complained about since 2009. What could this mean for the GT-R? According to the article, Nismo could be looking to raise horsepower from the current 545-hp mark to more than 570 hp, and handling upgrades could give the car a 'Ring lap time of seven minutes and 22 seconds, which as Top Gear points out, is four seconds quicker than the new 911 GT3.

The 11 best scenes from the 2015 Goodwood Festival of Speed

Over the last three days, the Goodwood Estate has played home to the eponymous Festival of Speed. Thrown by the biggest gearhead in the British aristocracy – Charles Gordon-Lennox, the Earl of March and Kinrara – the Festival of Speed is essentially a tremendous, gasoline-fuelled party, complete with a very large lawn sculpture, that features the world's hottest, weirdest, fastest, and loudest race, production, and historic models. While there are quite literally dozens and dozens of videos from the event – not to mention the full-day replays (of which only day one is available, at present) – we've sifted through them to pluck away the very best. There's stuff from the official Goodwood YouTube channel, as well as several videos from automakers and other third-party channels, and it's all available below. 2015 Ford Mustang GT350R Looks Barely Controllable If you thought the highest-performance Ford Mustang would somehow get more tractable or civilized once it moved to an independent rear suspension, this video shows you have nothing to worry about. Watch as an unnamed driver wrestles the new Shelby GT350R and its flat-plane, 5.2-liter V8 up the hillclimb circuit. Even with the new suspension and sticky tires, this Mustang wants to go any direction but straight, especially following its launch. 2016 Ford Focus RS, Is Very Loud, Blue Ken Block makes his first appearance on our list. Before he steps into his Hoonicorn Mustang, though, the Gymkhana expert tackled the hill in the all-new Focus RS. The vicious bellow of the 2.3-liter, turbocharged four-cylinder is the star of this commentary-free video, although the gorgeous Nitrous Blue paint job is a nice accompaniment, as well. 1965 Ford Mustang Hoonicorn Runs Hill, Nearly Kills Lord March Mr. Block's two runs behind the wheel of the Hoonicorn were, unsurprisingly, very eventful. While one attempt goes off without a hitch, seeing the American rally driver slip and slide his way to the top of the hill while taking a short break for a donut, the other is slightly more dramatic. Block, along with Lord March in the passenger seat, carries a bit too aggressive an angle into a turn and nearly puts the NASCAR-powered Mustang into the hay bales. Check out the first video above, and the second one below.
