Even with advances in vehicle technology, both conservation and methods for reducing the non-renewable hydrocarbon fuel consumption of existing vehicles are needed to decrease the petrol consumption and the greenhouse gas emissions. These factors have raised global interest in electric alternatives. Several large manufacturers are starting production of hybrid electric, and completely electric vehicles. Currently the performance and range of these vehicles is measured using standardised tests, called driving cycles.
These methods have been adapted from the speed profile testing used to measure fuel economy and emission levels in internal combustion powered vehicles. Research suggests that such testing does not accurately describe economy or emissions in real driving conditions, so further methodology is required.
The aim of this project was to assess the performance of the electric alternatives of the commercial vehicles, and measure energy economy by conducting the standardised tests.
