General Motors has unveiled the first teaser image of its new Chevrolet Colorado pickup truck, but it may be some time before U.S. audiences get to drive it.

While Chevy's marketing tends to play up the American aspects of its vehicles, the new pickup won't be debuting in North America first – that honor goes to Thailand. The truck will make its world debut at the Bangkok International Motor Show on March 25th.

"Thailand was chosen as the site of the global debut because of the popularity of pickup trucks and the growing importance of the Thai market to Chevrolet," a GM press release says. "In 2010, the pickup truck segment alone accounted for 43 percent of vehicles sold in Thailand. The new Colorado will go on sale in Thailand later this year."

In fact, the truck hasn't even been officially confirmed that it will appear in American showrooms at all, although PickupTrucks.com previously reported that both the Colorado and a new version of the GMC Canyon are on the way.

The new Colorado appears to retain the medium size of its predecessor while also taking some design cues from the Chevy Equinox SUV, which has been a big hit for GM.

Drivers in the market for a pickup truck may want to head down to New Jersey State Auto Auction, which has a wide variety of makes and models available for purchase.
