In a bid to green up its act, online retail giant Amazon has put in an order for 100,000 battery-electric delivery vans from Michigan-based EV startup Rivian. Those vans will sit atop the very same Rivian "skateboard" architecture that will underpin the startup's R1T pickup truck and R1S utility vehicle, not to mention a forthcoming luxury crossover from Ford's Lincoln brand. But beyond that, not much was known about the delivery vehicles - until now.

Amazon this week provided us a glimpse at its future pure-electric Prime delivery vans, giving us our best idea yet of what to expect.
