2014 Nissan 370Z Nismo

Michigan is one of those places where we can sub-divide the seasons into good and bad portions, with each producing a noticeable shift. The week prior to my time in the 2014 Nissan 370Z Nismo, it was 65 to 70 degrees and sunny, all week long. Anyone care to guess what the following week was like?
Windy, cold and damp weather typified my week in the Z, with temps hovering around 55 degrees and several days of showers. Yes, I got the first week of the bad part of fall. The Z was hardly happy during its time with me, but we both persevered, and I made a point of sprinting out to the garage anytime the ground seemed remotely dry enough to test this striking two-seater. That enthusiasm waned quickly, though, as the week wore on.
By all accounts, the Z is a car that I should like. It's an uncompromising sports car, but as I discovered during my travels, sometimes a little compromise is welcome, and living with a car like the Z - particularly the angrier, Nismo-tuned model - quickly becomes a case of too much of a good thing.

Nissan Leaf battery cells put through torture test, live to charge again

One minor chink in the armor of the Tesla Model S is that a small number have caught fire, once their battery packs were penetrated. Nissan Leaf drivers, however, might just be able to weather such an event without an ensuing CarBQ. Our evidence for such a claim? A video that has surfaced of cells from a Leaf pack undergoing a battery of torture tests (pun somewhat-ashamedly intended). Shared by folks at the Hybrid Auto Center in Las Vegas – who offer for sale, among other things, used Leaf lithium battery modules – the footage shows salvaged cells being brutally assaulted with a screwdriver, and later, a propane torch. Granted, these tests are not the same thing as flinging a piece of metal into a working pack at 70 miles per hour, but they do claim to show that a puncture does not always equal a fire. Oh, and don't try this at home. When pierced through by the flat head tool, there is no explosion or eruption of flame. Instead, a rather modest wisp of smoke shyly emerges as the electrolyte next to the shorted area of the fully-charged foil pouch reacts with the influx of oxygen. Again and again, the blade descends, until the cell is riddled with holes. No fire. Amazingly, when connected with a voltmeter afterward there are still plenty of signs of life, and when it is charged and discharged (off-camera), it reportedly suffers only a slight loss of charge capacity. The video goes on to show another cell attacked with open flame with similar results. While the demonstration is, perhaps, somewhat crude, the message it sends is loud and clear: lithium batteries can be safe and rather robust, despite some freak accidents.

Nissan EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.
