Those hoping for a new Chevy Tahoe or GMC Yukon will have to wait another 18 months.

General Motors' all-new Chevrolet Silverado and GMC Sierra pickup trucks are expect to arrive on dealer lots during the first half of 2013, but it could be another year before we see updated versions of their SUV counterparts.

Speaking with the Detroit Free Press, GM North America President Mark Reuss revealed that redesigned versions of the automaker's full-size SUVs - the Chevrolet Tahoe, Chevrolet Suburban and GMC Yukon - won't hit the market until early to mid-2014. The Tahoe, Suburban and Yukon share the same basic architecture as GM's full-size trucks.

Reuss didn't give an explanation for the year-long delay. Although GM's full-size SUVs aren't as popular as they once were, they still represent an important part of the automaker's portfolio - Reuss estimates that GM owns a 70 percent share of the SUV market.

2014 will also see the market launch of a redesigned mid-size truck intended to replace GM's aging Chevrolet Colorado and GMC Canyon. Already revealed as a global model, the next-generation Colorado will be built at GM's Wentzville, Missouri. It is unclear if GM will manufacture a GMC version of the mid-size truck.
