Racers spark up the night at Spa 24 Hours

By not hosting the top, factory-supported LMP1 endurance machines, the Spa 24 Hours doesn't carry quite the same level of prestige as the 'round-the-clock challenge of Le Mans. The Belgian event certainly shouldn't be ignored, though. Rolling through big elevation changes in the verdant forest, the famous circuit is one of the most beautiful places in the world to hold a race. It offers a real test to drivers, too, with corners like the famous uphill flick at Eau Rouge. In preparation for this year's event on July 25, Nismo is presenting this fantastic collection of short clips from last year's running. The video highlights some wonderfully artistic slow-motion shots of the cars taking on the course. Rather than just putting the sole focus on the company's own GT-Rs, Nismo includes glimpses at the vast array of machines competing in the race, including cars from Mercedes-Benz and Audi. As the sun falls and the track is bathed in darkness, eventually all you can discern are headlights and sparks erupting from the cars as they snake up Eau Rouge. Motorsports fans know that the sport can be beautiful when it's captured from the right angle, and Nismo's editors definitely find those fantastic shots for this minute of video.

'Car Wars' says Ford, Honda to pick up share, Fiat-Chrysler ambitions downplayed

Don't look for a tremendous shifts in automotive market share over the next three years because it might not be coming. That's at least according to the annual Car Wars report by John Murphy, from Bank of America Merrill Lynch Global Research.
In the report's analysis of automakers' market share from 2013 to 2017, it predicts only small changes among the major companies. Ford and Honda see the biggest positive effect with an estimated 0.5 percent increase in their shares over the next three years; to 16.2 percent and 10.3 percent respectively. On the flip side, European automakers and Nissan are expected to lose 0.2 percent each to fall to 8.3 percent and 7.8 percent each respectively. The rest of the industry is predicted to hold steady as it is now.
The biggest loser in that prediction might be Fiat-Chrysler Automobiles. The report certainly throws a wet blanket on its plan for significant gains in market share. Murphy told The Detroit News that the company's goal was "almost unattainable."

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.
