In the years since hybrid vehicles were first introduced, alternative fuel cars have grown significantly in popularity. While they are nowhere near outnumbering gas-powered models on the road, General Motors recently projected that it would have as many as 500,000 cars and trucks on the road that are partially or completely run with electric power within the next four to five years.

"The plug-in offers a unique opportunity to change the way people commute. Plug-based solutions will play a significant role in our technology portfolio going forward," said Mary Barra, senior vice president of GM's Global Production Development. "What started out as a technology proofpoint… has turned into a real-world starting point to push EV technology further and faster than we thought possible five years ago. The unique propulsion technology pioneered in the Volt – the same technology that will be featured in the Cadillac ELR – will be a core piece of our electrification strategy going forward."

General Motors is far from the only automaker that offers alternative fuel options in its lineup. In fact, most major car companies manufacture hybrid and electric models these days. Many of these models, such as the Toyota Prius, Chevy Volt and Honda Insight, have been on the market for a number of years. This means that alternative fuel options are becoming more available to used car shoppers, and those who are in the market for a green car may be able to find the ride they're looking for at New Jersey State Auto Auction.

The dealer carries a wide selection of makes and models, including hybrid vehicles as well as fuel-efficient compact cars and sedans. Even if drivers aren't quite ready to make the switch from gas-powered to hybrid or electric, they'll still be able to drive away in a car that can help them save some money at the pump.
