Nissan Xterra discontinued after 2015

Another great big subtraction in the choice of proper off-roaders comes with news from Edmunds that the Nissan Xterra will meet its maker after the 2015 model year. Sales of the body-on-frame SUV introduced in 1999 declined seven percent last year compared to 2013, a total of just 16,505 getting off dealer lots. That's about 1,800 more sales than the Toyota FJ Cruiser achieved for the year, another rugged trail runner recently dispatched into the ether. Meanwhile, the king-of-the-hill Jeep Wrangler almost matched those annual sales number each month in 2014; it moved 19,235 in May alone. Nissan hasn't exactly cared about the Xterra for years; Edmunds reported in 2013 that Nissan was "mulling the Xterra's future" and would take a year to decide if it was going to keep going. But it has been clear for years that the company wasn't too interested in its hardcore off-roader in spite of its "enthusiastic fan base inside and outside the company." The last visible refresh came in 2009, when it was 4Wheeler magazine's SUV of the Year, the next minor feature updates not arriving until 2014. And the Nissan-backed off-road triathlon series the Xterra was named for died in 2006. That's why there's no business case for throwing money at re-engineering the Xterra's safety and emissions specs, especially in a world gone crazy for subcompact crossovers. We contacted Nissan for comment on the report and asked if another Nissan vehicle, like the Rogue, would be positioned as a near-replacement, as has been speculated before. Product communications director Dan Bedore told us, "Nissan has made no announcement as to the future status of Xterra. For proprietary reasons, we do not discuss future product plans or comment on media speculation about future plans." Right now we can hear the Jeep Wrangler at the top of the mountain screaming, "Nobody wants a piece of this? Really?!" So come on, General Motors - it's up to you now.

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.

Here's how to follow this weekend's 24 Hours of Le Mans

In the pantheon of motorsports, the 24 Hours of Le Mans stands as one of the great endurance challenges to man and machine. This year's event in France already looks to be one for the ages with Porsche setting record-breaking times in practice and the competition debut of Nissan's front-engine, hybrid racer. Thankfully, there's a massive list of ways to follow this automotive attraction. Reilly Brennan, the Executive Director of the Revs Automotive Research Program at Stanford University, and a friend of Autoblog, has once again assembled a helpful couch-kit to organize many of the options. Unfortunately, the old-school way of just turning on the television might be the most frustrating way to watch Le Mans this year. Fox Sports 1 and 2 are carrying about half the race, but the coverage bounces between them seemingly at random. The broadcast begins on Fox Sports 2 at 8:30 AM Eastern ahead of the 9:00 AM start and lasts there until 12:00 PM. Things don't pick up again until 7:00 PM Eastern on Fox Sports 1 for an hour, and the channels swap back and forth more from there. The Fox Sports Go streaming app offers more, but even it stops showing the race a few times. Thankfully, streaming Le Mans is easy. If you can't dedicate 24-hours on the couch, Radio Le Mans lets you listen to audio commentary anywhere with some of the best announcers in the biz. The Automobile Club de l'Ouest, the governing body for the race, also offers an official video stream in an app for $9.99. For a really low-tech solution, the official Twitter is another choice. Brennan is keeping his list updated with coverage changes. You can also check out and download the spotter's guide (from Nissan) in the gallery above. Enjoy this year's race. If you miss anything, don't worry; expect a full report from Autoblog. In fact, editor-in-chief Mike Austin is attending Le Mans this year, so follow him on Twitter for on-the-fly impressions.
