The new all-electric GMC HUMMER EV EarthCruiser is a zero-tailpipe emission vehicle fully integrated onto the HUMMER EV Pickup chassis.

"We are proud to work with GMC on the design and manufacturing of such an exceptional product. It feels right, it feels like it belongs," said EarthCruiser CEO and Founder Lance Gillies. "Using our years of overlanding expertise, we have ensured nothing is out of place, unnecessary or wasted in this vehicle. This collaboration with the GMC team has provided the perfect opportunity to demonstrate the zero-tailpipe emission possibilities for overland and recreational vehicle travelers. We have produced a comfortable, capable product, built to a high caliber of excellence – one that our customers can take pride in.”
