Monthly fuel economy of the retrofitted Honda Civic during the first 9 months of the fleet test. DOE researchers attributed the significant fuel economy reduction for May, June, and July as most likely being due to significant mountain driving and the likely use of the vehicle’s air conditioning.

While there are no 48 V models in production today, these are the next phase of an incremental multi-generational product plan for cost-effective improvement in vehicle fuel economy. A key question for the segment is the nature of the energy storage for the system. Noting a predicted 3.7 GWh of the total market.

In terms of the status of the three electric-drive technologies, Pike notes that: Hybrid buses are a mature technology, and are generally best suited for lower speed, stop-and-go driving. North America is the leading market for this technology, with hybrids capturing 30% to 40% of annual transit bus sales. Li-ion batteries.

We believe the hybrid-electric bus trial will show how improvements in transport technology can deliver air quality improvements and reduce our carbon emissions. It is estimated this hybrid-electric technology will provide a saving of around 20 per cent on fuel and greenhouse gas emissions compared to a conventional diesel bus.
