Plug-in hybrids use no fossil fuel during their all-electric range and produce lower greenhouse gas emissions if their batteries are charged from renewable electricity.

This period is the vehicle's all-electric range.

Once a plug-in hybrid has exhausted its all-electric range in charge-depleting mode, it can switch into charge-sustaining mode automatically.

This contrasts with a charge-depleting trip which would be driven within the limits of a PHEV's all-electric range.

If the vehicle is driven less than its all-electric range and plugged in, it may be possible to use only electric power.

These changes will increase the Volt's all-electric range but charging will take slightly longer.

Although there is no technically mandated minimum all-electric range, future state and/or federal legislation may address this for policy purposes.

Toyota plans to conduct road tests to verify its all-electric range.

Among other challenges, this test has allowed to experience the all-electric range at low temperatures, which has been a disadvantage of plug-in vehicles.
