Abstract This study presents the energy consumption of Battery Electric Vehicles (BEVs) and Internal Combustion Engine (ICEVs: Petrol, Diesel) over more than 100 driving cycles. This aims at identifying the relative impact of a range of traffic conditions on the energy consumption of powertrains. Minimum consumption of BEVs appears at low-speed urban traffic, because of regenerative braking and high part-load powertrain efficiency. The optimum consumption of ICEVs was found at higher speeds, typical of rural-suburban environments. Traffic speed restriction in urban networks can further improve BEVs consumption, while speed increase would improve ICEVs. Congestion mitigation delivers 13%, 25%, 17% gains on average for BEV, Petrol and Diesel respectively. Gains are larger for ICEVs at lower speeds (25 km/h) and less so for BEVs in higher speeds (45 km/h). Any benefits of traffic interventions differ between the two vehicle types and current traffic plans need to take future powertrain particularities into account.
