The Sierra EV is a new electric pickup that emphasizes power and versatility. Taking a page from the old Chevrolet Avalanche, the midgate separating the cabin from the cargo bed can fold out of the way to create nearly 11 feet of load floor. The rear window can be removed completely, too. GMC offers 170kWh and 205kWh batteries, the latter good enough for more than 700 km of range. Similar to the Hummer EV, a CrabWalk feature enables diagonal moves.
