Consider what we heard last week: Faraday Future unveiled an out-of-this-world concept car showing high-end car buyers that it means business.

Chevy's new Bolt, arriving in late 2016 with a price tag of about $30,000 after incentives, meanwhile, will beat Tesla's mass-market car to the punch.

Also showing off some kind of electric concept were Volkswagen, Mercedes, Toyota, and Audi, to name a few.

It's not as if there aren't other electric vehicles out there already, but they are all limited to about 100 miles in range (on a good day) on a single charge. The new entrants aim to deliver 200 to 300 miles. That's Tesla's sweetspot, and it's where anyone who wants electric vehicles to compete with gas-burning cars at a time of $2-a-gallon gas needs to go.
