- Battery degradation.
Hybrid car batteries degrade over time, which can reduce the car's fuel efficiency. However, the rate of degradation is relatively slow, and most hybrid car batteries will still provide good fuel efficiency even after several years of use.
- Wear and tear.
Just like any other car, hybrid cars experience wear and tear over time. This can include things like tire wear, brake wear, and engine wear. These factors can all affect the car's fuel efficiency.
- Driving conditions.
The fuel efficiency of a hybrid car can vary depending on the driving conditions. For example, hybrid cars get better fuel economy in city driving than on the highway. They also get better fuel economy in warm weather than in cold weather.
