- The US government estimate of fleet maintenance costs found that battery-electric vehicles (BEV) have about 40% lower cost when compared to internal combustion engine vehicles (ICEV).
- Hybrids (HEV) and plug-in hybrids (PHEV) also save money.
- NB this 4c per mile difference across the nearly 2 billion miles federal government vehicles covered in 2019 equates to $78 million a year in savings, and that doesn’t account for fuel costs.
