Five awesome Lego car creations

Lego cars are among our favorite toys. They're fun for play, and if built properly, great to display. With that in mind, we've crafted a list of some of the best creations we've seen. Some are on sale now, while others are merely the work of fanciful enthusiasts. There are even a couple that you definitely cannot buy (we'll explain).
Our choices are diverse, including everything from a diminutive 1969 Chevy Corvette to a fullsize Ferrari Formula One racecar. These are just five projects that caught our eye - there are many more out there - so if you don't see your favorite Lego car on the list (or if you have your own creation), please tell us about it, in Comments.

Ferrari reopens wind tunnel after 18-month refurb

Ferrari is not a company used to being behind the curve, but if you've been wondering how the Scuderia has lost so much territory on the Formula One circuit to a relative newcomer like Red Bull, part of the answer could come down to its wind tunnel.
Seriously, the wind tunnel? Yes, the wind tunnel. Aerodynamics play an increasingly vital role in F1 racing, and while Red Bull has one of the best in the business, Ferrari's hasn't been running right for some time now.
A year and a half ago Ferrari shut down the galleria del vento at its headquarters in Maranello, citing problems with "correlation" - that is, a major discrepancy between the results it got in the wind tunnel, in CFD computations and on the racetrack. Having narrowed the problem down, the Scuderia embarked upon a major overhaul. It's been using Toyota's facility in Cologne, Germany, in the meantime, but as team principal Stefano Domenicali put it, not having your own wind tunnel on premises "is like playing basketball with one hand behind your back." Now the renovations reportedly complete, however, and Ferrari will begin using its wind tunnel again next month.

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."
