Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.

Nissan Juke to get higher-performance Nismo RC model

It's hard to find more giggles for your crossover dollar than the Juke - regardless of how you feel about the way it looks, the singularly styled nichemobile from Nissan is very entertaining to drive. Yet we've always felt that the platform had more in it, and evidently its Japanese parent agrees, having recently bracketed the googly-eyed turbocharged CUV with a new Nismo model and the barking mad built-to-order Juke R. At present, neither the Juke Nismo or the GT-R-powered Juke R are sold in North America, but the former has already been confirmed for sale here.
Even when it does reach our shores, there will still be a heck of a lot of whitespace between the mild performance upgrades of the standard Nismo and the half-mill R model, and to hear the UK's Car tell it, Nissan has plans to plug that gap, too. According to its report, the automaker will shortly offer a Juke Nismo RC that will have roughly 20 horsepower more than the basic Nismo (which itself has 197 hp, nine more than the base Juke). The RC will apparently feature a lower, stiffer suspension, upgraded brakes and a unique exhaust and intake for a snarlier soundtrack. Both front-and all-wheel drive models are planned, as are manual and CVT transmission choices.
No word yet on the RC's pricing or even North American availability, but the regular-strength Juke Nismo is expected to arrive shortly, and Nissan is also said to have big plans for its performance nameplate, so we wouldn't rule it out.

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.
