Which of the following is NOT a benefit of fuel-efficient vehicles?

Fuel-efficient vehicles are designed to maximize energy from fuel, leading to various benefits that positively impact the environment and consumer expenses. One major advantage is lower overall emissions, as these vehicles typically produce fewer pollutants, contributing to cleaner air. Reduced fuel costs result from vehicles that consume less fuel for the same distance, which is financially beneficial for drivers. Additionally, fuel-efficient vehicles often require less frequent refueling due to their efficiency, allowing drivers to spend less time at the gas station.

In contrast, increased vehicle weight does not align with the benefits of fuel-efficient vehicles. Generally, heavier vehicles require more energy to operate, which can lead to reduced fuel efficiency. Consequently, this choice does not represent a benefit but rather a factor that could detract from the advantages associated with fuel-efficient automobiles.
