Buying the Bollinger Motors B4 (Class 4 chassis cab) in United States
- 1Range: the 185 miles figure quoted in United States is on the EPA (US Environmental Protection Agency) rating. EPA numbers are conservative — many drivers match or beat them in mild weather, but expect 20–30% less in deep winter.
- 2Charging: a 158 kWh pack refills overnight on a 240V Level 2 home charger; on the road you'll use NACS (Tesla-style, now the US standard) plus CCS1; Level 2 at home, DC fast on the road — this model does 20-80% in 65 min (125kW DC CCS1).
- 3Incentives: The federal Clean Vehicle Credit (up to $7,500) ended on 30 September 2025 — there is no federal EV purchase credit on vehicles bought after that date. Savings now come from state programs (e.g. Colorado's EV tax credit, New Jersey's point-of-sale rebate + EV sales-tax exemption) and utility rebates — check your state.
- 4Climate: Northern states (MN, MI, NY) see meaningful winter range loss — size the battery for cold-weather commuting.
- 5Fit: the Bollinger Motors B4 (Class 4 chassis cab) suits daily commuting best — for cross-state trips, map fast-charging stops in advance.
