Jeff Bezos is taking on Rivian and Elon Musk's Tesla with the release of a budget-friendly electric vehicle. Here's what the Slate looks like.

American EV startup Slate, backed heavily by Amazon founder Jeff Bezos, has just launched its first model – a build-it-up, all-electric vehicle that starts life as a pick-up truck but can be added to so that it ends up as anything from a family SUV to having a fastback 4x4 look.

Slate Auto, an electric vehicle startup backed by Amazon CEO Jeff Bezos, unveiled its inaugural truck the company says starts at a price of $20,000 for the most bare-bones version, a lower price than competitors including Elon Musk’s Tesla vehicles.
