A massive 387 kWh battery supplies nearly 300 miles of range and it can carry up to 90 people — around three classrooms full of kids.

Large electric school buses with around 100 miles of range can cost $300,000 to $400,000, up to four times the price of a diesel-powered school bus. However, maintenance costs are lower and the US Environmental Protection Agency (EPA) recently launched the Clean School Bus Program providing $5 billion over five years to replace existing school buses with zero-emission and low-emission models.
