What does a world-class downhill skateboarder drive? Something very cool

Kevin Reimer has an interesting career and a fascinating car. The resident of Vancouver, BC is a professional downhill skateboarder - which we now know is a thing you can be - who sees a lot of commonality between his extreme occupation and his cherry 1991 Nissan Skyline GT-R.
The subjects of the latest Petrolicious joint, Racing Champions, Reimer waxes philosophical about skateboarding and driving down some of the same routes. You'll not be surprised to hear that riding the curves of a mountain slope, be it on a deck or in a bucket seat, both rely on grip and nerve in various measure. Scroll down to see for yourself, and don't miss the rest of our Petrolicious library when you're done.

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.

Check out Nissan's clever digital Smart Rearview Mirror

Using cameras in place of a car's rearview mirrors has long been a feature of pie-in-the-sky concept cars, although so far, it's failed to translate into the world of production vehicles. Nissan is looking to change that, though, with its new Smart Rearview Mirror.
With a flick of a switch, drivers can jump back and forth between what they'd normally see through the rearview mirror and the camera's feed from the back of the car.
The Smart Rearview Mirror blends everything we know about traditional reflective glass mirrors with a video feed from the rear of the car into a form factor that's immediately recognizable to the average motorist. With a flick of a switch, drivers can jump back and forth between what they'd normally see through the rearview mirror and the camera's feed from the back of the car. The mirror itself features an integrated LCD display with a four-to-one aspect ratio.
