1. Fuel economy

Fuel economy is a measure of how efficiently a vehicle uses fuel — in other words, how far it can travel using a certain amount of fuel.

  • Saves money on fuel costs.
  • Reduces pollution and CO₂ emissions.
  • Helps you drive smarter by choosing more efficient vehicles or habits.
  • What Affects Fuel Economy?
    • Driving style - Aggressive driving uses more fuel.
    • Speed - Higher speeds = more fuel use.
    • Vehicle type - SUVs/trucks use more than small cars.
    • Weight - Heavier vehicles = lower economy.
    • Tire pressure - Low tires reduce efficiency.
    • Road conditions - Hills, traffic, and poor roads can lower it.
