This is the data set associated with the journal article titled 'A Computationally Efficient Framework for Modelling Energy Consumption of ICE and Electric Vehicles'. The data files are in MATLAB file format.

Figure 4 was generated using the vehicle speed profiles of an electric bus (EB) when it operated in London and of the EB's baseline simulation model, and using the state of charge (SOC) profiles of the EB when it operated in London and of the EB's baseline simulation model.

Figure 5 was generated using the electricity consumption of the EB's baseline simulation model and of the EB's computationally efficient model for different drive cycles. It shows how the proposed computationally efficient model's electricity consumption compares with that of the baseline model.

Figure 6 was generated using the speed profiles of a diesel heavy goods vehicle (HGV) when it operated on-road and of the HGV's baseline simulation model, and using the fuel consumption profiles of the diesel HGV when it operated on-road and of the HGV's baseline simulation model. It also contains the road elevation profile.

Figure 7 was generated using the fuel consumption values of the diesel HGV's baseline simulation model and of the HGV's computationally efficient model for different drive cycles. It shows how the proposed computationally efficient model's diesel consumption compares with that of the baseline model.

All the files were generated using MATLAB software package from Mathworks.
