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 Altima and Sentra to get Murano-inspired design redo

The Nissan Altima and Sentra sedans are both very competent, economical, comfortable and well-equipped ways of getting from A to B. They're also both decidedly boring to look at, which is not a good trait in their increasingly style-driven segments.
To rectify this, Nissan is planning design overhauls for its mainstream, with the Sentra adopting the sportier, Euro-style looks of the Pulsar, according to The Car Connection. While that (sadly) won't mean the five-door Pulsar will come to the US market, fitting the European stylings to the Sentra should go a long way towards broadening the car's appeal.
That parcel of information comes from Nissan design boss Shiro Nakamura, who spoke to The Car Connection at last week's Paris Motor Show.

2014 Nissan Juke Nismo RS amps up the funky crossover

Nissan unveiled an even hotter version of the hotter Juke Nismo at the Los Angeles Auto Show - the Juke Nismo RS, a 215-horsepower crossover that may be the most hardcore model in the compact CUV segment (until we can convince Mazda to build a Mazdaspeed CX-5, that is).
The 215 hp and 210 pound-feet of torque represent bumps of 18 hp and 26 lb-ft over the standard Juke Nismo thanks to a revised ECU, a new exhaust with a larger diameter tube, and stronger connecting rods. This amped-up engine can be mated to the owner's choice of a six-speed manual, which takes advantage of a stronger clutch cover and dual-mass flywheel, or an Xtronic continuously variable transmission (although the CVT model loses four horsepower and all of the extra torque that the Nismo RS enjoys).
"We expect drivers to feel a noticeable increase in acceleration - especially the manual transmission model - in the RS versus the regular Juke Nismo. It also holds peak torque longer. Combined with the Helical Limited-Slip Differential, which helps reduce torque steer, the sense of driving excitement is unmatched in the Juke lineup," said Pierre Loing, Nissan's vice president of product and advanced planning and strategy.
