Even if you don't have any drugs to hide, who doesn't love a hidden compartment in a fancy Denali pickup truck?

The Sierra EV AT4 may be missing some of the luxury features and trick electronics that come on the Denali, but that doesn't stop it from being a lot better.

GMC says these Hummers "redefine what a mid-size EV can do off-road," and despite being billed as concepts they don't look that far-fetched.

The system could detect uneven loads, or loads that exceed a truck's payload, factoring in suspension compression and whether the trick is parked on a slope.
