Moments ago, GM CEO Mary Barra unveiled the all-electric Chevrolet Bolt at CES, providing the first look at what may be the most significant vehicle the automaker has built in decades. The little EV may look like just another five-door compact, but two figures make it an engineering masterstroke: 200 and 30,000.

That first number is its range: 200 miles on a fully charged battery. That's a number exceeded only by Tesla, whose cheapest model starts north of $70,000. And that brings us to the second number. Chevy promises the Bolt will cost less than $30,000 after the $7,500 federal tax credit. Together, they make the Bolt the first EV that delivers excellent range at a great price. It is the electric car for the masses.
