Nissan Sentra crash rating improves, now Top Safety Pick [w/video]

After a poor showing in the hands of the Insurance Institute of Highway Safety back in 2013, Nissan is back for another round of crash testing with its 2015 Sentra, and it's walking away with a Top Safety Pick. The compact sedan's small overlap front crash test rating improved from "poor" to "good", owing to internal improvements to the A-pillar, door sill and front structure, IIHS said in a statement. The dummy, in this most recent test, was at a low risk of injuries because of the structural changes. Take a look at video of the Sentra's small overlap crash test, available up top, and the official press release down below. 2015 Nissan Sentra earns TOP SAFETY PICK award ARLINGTON, Va. - The 2015 Nissan Sentra has improved from a poor to good rating in the Insurance Institute for Highway Safety's small overlap front crash test, qualifying for the TOP SAFETY PICK award. The small car's front structure, A-pillar and door sill were modified to reduce intrusion in small overlap crashes. In addition, the side curtain airbag was lengthened to protect the driver's head. In the latest test, the driver space was maintained well, with maximum intrusion of less than 5 inches at the lower door hinge pillar. The dummy's movement was well-controlled. The head hit the front airbag and stayed there until rebound, while the side curtain airbag had enough forward coverage to protect the head from contact with side structure and outside objects. Measures taken from the dummy indicate a low risk of injuries in a crash of this severity. In contrast, the 2013-14 Sentra didn't hold up as well in the test. Intrusion measured as much as 13 inches at the lower hinge pillar. The dummy's head slid off the left side of the frontal airbag, and the side curtain airbag didn't offer adequate coverage. Measures from the dummy indicated that injuries to the left leg would be possible in a crash of this severity. Introduced in 2012, the small overlap test replicates what happens when the front corner of a vehicle collides with another vehicle or an object such as a tree or a utility pole. The Sentra's good ratings in the moderate overlap front, side, roof strength and head restraint tests carry over to the 2015 model year. To qualify for the 2015 TOP SAFETY PICK award, a vehicle must have good ratings in those four tests and a good or acceptable rating in the small overlap test. Related Video:

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.

In case you forgot, the Dubai Police supercar fleet is the coolest

Ever wonder why the Dubai Police have a fleet of vehicles worth millions and millions and millions of dollars? Why it has a Bugatti Veyron and a Bentley Continental and a Mercedes-Benz SLS AMG with sirens and light bars? Well, here's the reason. This video shows the fleet on display on the Emirate's roads and highways, while also reaching out to the people the police are meant to protect. It's an impressive display of machinery, to be sure. Alongside the Bentley, Bugatti and Mercedes, we spy a Ferrari FF, a Brabus G-Wagen, a BMW M6, a Nissan GT-R, an Audi R8 and a McLaren MP4-12C (although the latest Dubai Police car, the Lexus RC F, is absent). The video even has a very cinematic look and feel to it, which works well with the night scenes and the blues-and-twos of the exotics cruisers.
