Nissan 370Z Nismo Roadster Concept looks ready to roll

Honestly, we're kind of surprised this hasn't happened already. The Nissan 370Z Nismo is a pretty cool little package, better than ever in its 2015 model year iteration. So why not apply that same, go-faster, look-cooler formula to the topless Z Roadster? That's exactly what Nissan's done here in Chicago, showing the 370Z Nismo Roadster you see here. Aesthetically, it's pretty much the same as the coupe – except, of course, for the folding cloth roof that neatly stows behind the front seats. It's mechanically the same, too, with Nissan's 3.7-liter naturally aspirated V6 underhood, making 350 horsepower. Oddly, the concept car uses the company's seven-speed automatic transmission, but as Nissan explains, the majority of Z Roadster buyers spec their cars with the slushbox. "While it is only a design study at this point, we think the 370Z Nismo Roaster Concept would be a tremendous addition to the long and distinguished history of Z sports cars," Pierre Loing, Nissan's vice president of product planning in North America, said in a press release. It sure looks production-ready to us. Nissan 370Z NISMO Roadster Concept makes world debut at 2015 Chicago Auto Show - Combines legendary NISMO performance, style and technology with Nissan 370Z Roadster open-air motoring excitement - One-off design study created to gauge market interest in an ultimate factory Z® Roadster - Offers unique engine, suspension, exterior and interior features versus standard Nissan 370Z Roadster models – including 350-horsepower 3.7-liter V6 and NISMO-tuned suspension - Would join current Nissan 370Z NISMO coupe model, expanding NISMO lineup to five models As the heart and soul of Nissan performance for both the track and on the street, NISMO continues to set the standard for straight-from-the-factory enthusiast vehicles. The lineup of NISMO production models for 2015 includes the GT-R NISMO, 370Z NISMO, JUKE NISMO and JUKE NISMO RS. Yet as the popularity of NISMO models continues to grow – the 2015 GT-R NISMO is sold out, the 370Z NISMO accounts for 20 percent of total sales and JUKE NISMO models for about 15 percent – one group of performance enthusiast remains left out: Open-air sports car lovers. Enter the Nissan 370Z NISMO Roadster Concept, which makes its world debut at the 2015 Chicago Auto Show. The custom vehicle combines the long list of 370Z NISMO Coupe performance equipment with a modified 370Z Roadster body and interior.

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.

Nissan Qashqai caught looking sleek

The next-generation of the not-for-US-consumption Nissan Qashqai has been out doing some testing in southern Europe this week. And, if the dressed-in-trash-bags look is any indication, it's been doing a lot of roadwork so it can make weight for the big meet the weekend.
Nissan designers haven't been scared to take big design chances with recent new models, so expectations are that the Qashqai crossover will get a bold new visage for its generational changeover. What we see in these photos indicates a sleeker, slightly trimmer CUV however, with no trace of the bug-eyed look we captured recently on a testing Titan.
In the rest of the world, it's a good bet that the Qashqai will be powered by engines ranging from a 1.2-liter turbo up to a 1.6-liter forced-induction unit; that larger one good for something like 215 horsepower. Diesel powerplants will be in the mix, too, for the compact CUV, and word is that Nismo might get its hands on this Rogue cousin for the first time ever.
