What is Charge-sustaining Mode (Hybrid Mode)?

Plug-in hybrids switch to it when depleted. It works like a normal hybrid. Some allow saving charge. Some plug-in hybrids let drivers save battery charge for later, for example for city driving at the end of a trip, or even recharge the battery using the engine, which costs fuel. Official consumption figures for plug-in hybrids assume regular charging, so real consumption can be much higher if the car is rarely plugged in.

How it works

The system balances engine and electric use.

Why it matters for your car

Fuel consumption is higher. Charge regularly for efficiency.
