TECHNOLOGY / RANGE EXTENDING ENGINE
Once the battery is depleted, an all-new 1.5L SIDI high-efficiency engine kicks in. More efficient than the previous generation, this engine runs on regular unleaded gas and is able to achieve more power and torque at the same RPM, resulting in a GM-estimated 41 MPG combined city and highway and a total range of over 400 miles. Volt engineers were able to pack more energy into 96 fewer battery cells. In fact, the new battery has a capacity of 18.4 kWh, a 7% increase, while weighing 21 lbs. less than the previous model.
