- Common hybrid drive for Diesel-Electric and CNG-Electric, which can be extended to Pure Electric, CNG micro turbine and hydrogen fuel cell buses.
- Overall cost over the lifetime of the vehicle is lower, due to savings in running costs. Procuring cost is significantly higher.
- Regenerative electronic braking allows reuse of energy dissipated during braking.
- Very low and transient engine operation.
- Electrically driven auxiliary systems.
- Automatic Electric mode.
- Lithium-Ion battery pack provides better performance compared to Lead Acid pack.
- Smaller engine gives rise to less noise.
- Energy management strategies allows tuning to suit specific customer requirements, depending on the operations.
