Delving deeper into a fleet’s real-world performance

First published in Green Fleet March 2017

Cenex’s project manager Luke Redfern outlines how fleet operators can measure their own driver behaviour, route choice, traffic patterns and vehicle performance to compare against industry standards, and ultimately produce more accurate total cost of ownership and emissions modelling.

Over the last decade, the diesel engine has been the logical choice for fleets for economic and carbon-reduction reasons. Fleet owners and operators have refined their decision-making based on the ability to apply diesels across the full range of fleet operations. Despite the inherent efficiency of diesels, published data on fuel consumption has always been treated with a level of scepticism, and the majority of fleets have monitoring systems to record real-world fuel economy and carbon emissions for high-mileage vehicles. The cost-benefit ratio of deploying on-vehicle telemetry means low-mileage and grey fleet vehicles typically go unmonitored. However, data can carry over to these vehicles for reasonable assessments to be made. Now the logic of diesel-only fleet operations is under challenge as the motor industry has switched its investment to electrified powertrains. Its product ranges have an increasing number of battery-electric and plug-in hybrid vehicle options, and today’s fleet replacement investment decisions need to compare these available options with diesel.
