According to the documentation (https://carculator.readthedocs.io/en/latest/modeling.html#light-weighting), 3.57 kg of steel are replaced by 0.8 kg aluminium and 1.76 AHSS. In the documentation, it is also mentioned that AHSS is represented by conventional steel. However, in the file "A_matrix.csv" no AHSS or conventional steel is considered. According to this file, 0.8 kg aluminium replace 3.57 kg steel.

If the inventory is exported to an excel file, the electricity demand for "cathode, NMC-622, for Li-ion battery" and "cathode, NCA, for Li-ion battery" is not considered. For NMC-111 and NMC-811, it is considered.
However, in the file A_matrix.csv the electricity demand is considered for all technologies

When we do change the climate target for the IAM in InventoryCar, results remain unchanged.

ic = InventoryCar(cm, method="recipe", scenario="SSP2-PkBudg1150", indicator="midpoint")

I was wondering why the fuel consumption of ICEV and HEV is so similar. Thus, I had a closer look at the energy consumption model.

If I understand it correct, the recuperated energy is subtracted from the "motive energy". But shouldn't it be subtracted from the "motive energy at wheels" because the recuperated energy can be more or less directly used for propulsion.

If PHEV-d and PHEV-p are considered simultaneously with the "scope" parameter in the "CarModel", calculation is not possible. If PHEV-d and PHEV-p are considered separately, it works. It also works if "scope" is not used.

I used the newst version (but the problem existed already in older versions) and tried a calculation for 2030.

I think the probem is in: carculator_utils\model.py:728, in VehicleModel.set_share_recuperated_energy(self)
