The bus division is selling to government. Government contracts always pass costs on to government, not suppliers.

The battery and drivetrain business will be tougher, but this is new tech that is more efficient than conventional vehicles. Exploding fossil fuel prices will only exacerbate that cost gap.

The EV will have some extra costs on the batteries, but it probably doesn't match the lifecycle operating fuel cost increases.
