A closer look at the 2015 BMW M3 and M4

It's fair to say we're going to miss the E92 BMW M3. Its high-revving V8, flame-styled looks and excellent driving character made it quite simply one of the best cars of the 2000s. Its replacements, the new M3 Sedan and M4 Coupe have a lot to live up to.
We still have a few months to wait until we can drive the new cars, but that doesn't mean we can't get excited in the meantime, learning everything we can. To find out, we sent west coast editor Michael Harley onto the Detroit Auto Show floor earlier this week to talk about the new M cars with BMW product manager Victor Leleu.
If you want a concise, but highly informative rundown of these new cars, look no further than this video. Leleu talks about the styling, weight savings and engines in a lot of detail, making this an interview M fans aren't going to want to miss. Scroll down for the full video.

BMW, Ferrari, VW cars use tungsten mined by terrorists

Bloomberg Markets is reporting that BMW, Volkswagen and Ferrari have been using tungsten ore sourced from Columbia's FARC rebel terrorists. The extensive story focuses on Columbia's illegal mining trade and calls into question the provenance of the rare ore that is used not only in crankshaft parts production, but is also found in the world's computing and telecommunications industry for use in screens.
The ore is mined by the FARC (Fuerzas Armadas Revolucionarias de Colombia, or Revolutionary Armed Forces of Colombia - People's Army), and exported to Pennsylvania, where it is refined. The refined ore is then sent over to Austria, where a company called Plansee turns it into a finished product. Now, it's important to note that we aren't talking about the world's supply of tungsten here. In 2012, Plansee's American refinery purchased 93.2 metric tons of tungsten, valued at $1.8 million. That's peanuts, with the entire Colombian tungsten mining industry producing just one percent of the world's supplies.
That doesn't make indirectly supporting FARC any more acceptable, though. BMW, VW and Ferrari are all committed to not accepting mineral supplies from the Democratic Republic of Congo, which is also in the grips of a guerrilla insurrection funded, in part, by illegal mining. The same commitment would figure to extend to Colombian mining, but as BMW points out, it's difficult for a multi-national manufacturer to know where every item in its supply chain comes from. A company spokesperson says as much, telling Bloomberg, "These few grams out of the billions of tons of raw materials passing through the BMW supply chain are of no practical relevance."

Consumer Reports' first motorcycle reliability report finds Japanese brands ahead

Consumer Reports has released its first ever study of motorcycle reliability, and students of its ratings on cars might notice a suspicious similarity - Japanese brands require fewer repairs than the leading American or German brands.
The study analyzed the reliability of 4,680 bikes owned by CR subscribers and found that Yamaha had the best ratings, with just one in ten bikes built between 2009 and 2012 requiring a repair over a four-year period. The makers of the R1 and R6 sport bikes were closely followed by Kawasaki and Honda, while one out of every four of the rumbling bikes from Harley-Davidson experienced an issue. BMW had the worst rating of the brands represented, with one in three bikes having problems.
According to CR, neither Suzuki nor Triumph owners provided enough information for a reliable rating. Based on the responses received, though, Suzuki would have finished with the other Japanese brands and Triumph, being English, would have been one of the less reliable makes.
