TLDR
The results of the 2011 RAC Future Car Challenge as discussed by the authors reveal that the vehicle's power train type has the largest impact on energy consumption and emissions and the traction ratio, defined as the fraction of time spent on the accelerator in relation to the driving time, and the amount of regenerative braking have a significant effect on the individual energy consumption of vehicles.Abstract:
This paper analyses the results of the Royal Automobile Clubhallo’s 2011 RAC Future Car Challenge, an annual motoring challenge in which participants seek to consume the least energy possible while driving a 92 km route from Brighton to London in the UK The results reveal that the vehicle’s power train type has the largest impact on energy consumption and emissions The traction ratio, defined as the fraction of time spent on the accelerator in relation to the driving time, and the amount of regenerative braking have a significant effect on the individual energy consumption of vehicles In contrast, the average speed does not have a great effect on a vehicles’ energy consumption in the range 25–70 km/hread more
