SAN ANTONIO — If you were in downtown San Antonio on Tuesday or Wednesday, you might have eyed a few black mystery trucks driving around.

And, no, they don't belong to invading drug cartels or terrorist groups.

The trucks, draped completely in black canvas wraps covering the logos and camouflaging the exact shape, drove through the streets of downtown Tuesday afternoon and Wednesday morning.

Asked why the truck was covered, one driver said, "It's a prototype for a company that doesn't want anybody to know what it looks like."

The driver refused to name the company, but showed the truck's interior, which was also covered by fabric to conceal any logos.

However, the truck's specs appear to match up with online photos of the 2016 Ford F-250 prototype.

Ford spokesman Nik Ciccone said an in an email, "The only thing I can say right now is that the all-new Super Duty will use high strength military grade aluminum alloy, like in the all-new F-150, and production will start next year."

Car manufacturers and dealers commonly use the stealth-looking camouflages during test driving to conceal car models that have not yet hit the market.
