Chevrolet is reintroducing its best-known off-road badge for the 2014 Los Angeles Auto Show, with the return of the ZR2 on the all-new Colorado pickup. While we're plenty excited about this particular concept, it's what sits under the hood that we're most excited for, because this particular vehicle is motivated by Chevy's eagerly anticipated 2.8-liter Duramax diesel.
You would think that, given the popularity Ford has found for the F-150 SVT Raptor, its crosstown rivals would be all too keen to follow suit. But they haven't. The Ram Runner isn't a production truck, it's an add-on, and General Motors has barely even tried. That might change, but not in the way you might think.
