In August 2010, I proposed this wager to a fellow journalist: President Obama's declared goal was to get 1 million plug-in hybrid and all-electric cars on the road in the United States by 2015. I didn't think that goal was reachable by 2018, even with the huge subsidies that Obama backed - but if I was wrong about that, I'd buy my colleague a new plug-in hybrid Chevy Volt.
Now the 2015 car-sale data are in; time to review the bidding. Americans bought a record 17.5 million passenger vehicles in the United States, of which 116,548 - 0.67 percent - were either plug-in hybrids or all-electrics, according to insideevs.com. That was about 6,500 fewer than in 2014.
Automakers have sold 407,136 electrics (EVs) since they hit the market in 2010. That is 0.16 percent of the 250 million-plus U.S. passenger vehicle fleet. Assuming all are still on the road, carmakers must sell 300,000 this year and next to reach 1 million, or 0.3 percent of the fleet, by 2018.
