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.

BMW NA president says i3 beats Tesla EVs thanks to lighter all-around footprint

Those waiting for a full-out brawl between Tesla Motors head Elon Musk and BMW North America chief Ludwig Willisch will have to wait a bit. For the bloodthirsty, there are signs of some healthy competition and a little bit of green-car sniping between the two automakers. Willisch, speaking at the Detroit Auto Show earlier this month and responding to questions about Tesla, noted (without mentioning that company by name) that the production process of the German automaker's i3 plug-in was "greener" than any other. According to Business Insider, Willisch highlighted the fully recyclable materials used to construct the i3 as well as the hydropower used at the carbon fiber plant in Moses Lake, WA. Willisch also noted that the Tesla Model S is "very heavy on the braking. Our car feels just like a normal car. That's a big difference when it comes to driving," Automotive News said in a separate report. The latter model weighs about a third less than the Tesla, though it also has an EV range about a third as big. The BMW executive did allow that the Tesla did make a good proverbial "snowplow," not for its driving characteristics but for its ability to get more people conformable with electric vehicle technology. Musk was asked about the i3 in an August conference call and laughed before noting that the i3 had "room to improve." No word on whether Musk and Willisch will be sending each other Valentine's Day cards next month.

BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.
