Ford CEO Alan Mulally said he expects the company to start selling plug-in hybrids to the public in 5-10 years. This is the first time that Ford has offered a timeline for plug-ins hybrids.
A plug-in hybrid differs from a traditional hybrid car in that the battery is charged using a regular household outlet. The driver may be able to go about 30 miles a day on battery power alone (about the average U.S. commute) and then plug it into the house to charge over night. If one were to travel further, the car would switch over to gas.
This technology is off the drawing board and onto the streets already: Lots of people are taking matters into their own hands and converting their hybrid to be plugged in. Recently, Google announced plans to give more than $10 million to advance plug-in hybrid technology.
