BMW M4 Concept beckons the new golden child of M cars

Ushering in the next-generation of two-door M performance cars for BMW, the new M4 Concept was officially unveiled at the Pebble Beach Concours d'Elegance last night after an unceremonious embargo leak yesterday afternoon. The reality of the fact that we will never again have a new M3 Coupe is a little easier to deal with after browsing the M4 Concept's sleek and sporty lines.
As was the case with the Concept 4 Series Coupe, we expect the this M4 to transition from concept car to production coupe with very few changes. Among the features we's bet against making it into production include the front splitter and the exhaust tips - both made from carbon fiber. Other notable details are the aero-shaped mirrors, the subtle M stripes on the carbon fiber roof and the 20-inch wheels exposing big six-piston from brakes. If it were up to us, we'd say bring this car to production as is - except for the paint color.
There is still no word on the M4's powertrain or if it will even offer a manual geabox, but we would imagine that we'll be seeing this car in production form, complete with all of those details at the LA Auto Show.

BMW M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.

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."
