BMW X4 opens up alongside its boxier brother

It doesn't seem so long ago that BMW (not to mention Audi, Volvo and a handful of other European automakers) weren't in the crossover market. But it's been over a decade since BMW began producing the first-gen X5, and in the fourteen years since, the Bavarian automaker has steadily expanded its portfolio to include the X1, X3 and X6.
The next to join the family will be the X4, which is essentially to the X3 what the X6 is to the X5. That is to say, basically the same vehicle, only with an (arguably) more stylish but less utile roofline. Previewed in concept form at the Shanghai Auto Show half a year ago, the X4 has been snapped by our plucky paparazzi in the past, but this is the first time we've seen inside.
Not only that, but the prototype in question was spotted next to the current X3 on which it is based, which gives us ample opportunity to see the differences between them. Of course, that still primarily comes down to the slantback profile, because otherwise, the two are essentially the same inside and out. Or at least they will be: many of the differences between the two are expected to port over to the X3 when it's refreshed next year, including some subtle interior upgrades - just not the roofline.

The next-generation BMW M5 starts here

The next-generation BMW 5 Series hasn't even arrived yet, but BMW is hard at work testing the hottest version of the popular sedan – the sixth-generation M5. Now admittedly, these photos might not look much like an M5. The wheels are big, but not uncommonly so. There's no wild and crazy body kit, or hugely flared wheel arches. But what's that in the back? Are those four exhaust tips? Why yes, yes they are. And take a second look at those wheels. Notice the pizza-pan-sized brakes and huge calipers? Yet another M5 giveaway. But as our spies rightly point out, even though this does represent development work on the next M5, it's a very early prototype. That could also explain the charge port on the driver's side front fender, a feature that we've seen on other 5 Series prototypes. This does not mean the next M5 will be a plug-in hybrid, however. What the next M5 will likely be, though, is all-wheel drive. This isn't a huge surprise, considering that the Mercedes-Benz E63 AMG has already gone AWD, while the Porsche Panamera Turbo and Audi RS6/7 have always had four driven wheels. BMW has even hinted at just such a development, with former M boss Dr. Friedrich Nitschke going as far as saying AWD could arrive on the next M5. "On our cars we are thinking of all-wheel drive, but it won't come before we get the successor of the M5 and M6," Nitschke said in an October 2013 report. "That's the timing and it's not practical to react in the current life cycles." At this point, it's simply too early to guess at when or where the next-generation M5 will debut. We're expecting the next-gen 5 Series at either the 2016 Geneva Motor Show or Auto China 2016 in Beijing. The next M5 could join it, although it's possible it'd get its very own debut at a later date.

Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.
