Why is the Kia Niro's fuel economy better than its competitors?

I've been researching different hybrid SUVs and I noticed that the Kia Niro has significantly better fuel economy compared to its competitors. Can you explain the technical reasons behind this?

One reason could be that the Kia Niro uses a highly efficient powertain, made up of a 1.6L engine and an electric motor. This combination allows for better fuel economy and improved performance.

Another factor could be the Niro's regenerative braking system, which helps to recapture energy that is typically lost during braking. This energy can then be used to power the car, resulting in better fuel efficiency.

Additionally, the Niro's lightweight design and aerodynamic shape play a role in its impressive fuel economy. The lighter the car, the less energy is needed to move it, and the sleek shape allows for better air flow.
