Fuel consumption of cars
by Alex
Expert answer:
Quick answer
Cars often range from 20 to 30 mpg combined, though smaller hybrids can exceed 40 mpg while performance cars or big SUVs dip below 20.
Detailed answer
Fuel consumption in passenger cars revolves around factors like engine size, vehicle mass, and aerodynamics. A typical family sedan might pull 25–30 mpg, while economy-focused compacts or hybrids push the envelope, topping 40 mpg combined. Conversely, sports cars with turbocharged or large-displacement engines often live below 20 mpg.
Driving style—accelerating smoothly, coasting before stops—can yield noticeable improvements. Regular maintenance, like timely oil changes and proper tire inflation, keeps consumption near factory estimates.
As technology evolves, many vehicles feature start-stop systems, continuously variable transmissions (CVTs), or partial electrification to squeeze out more mpg. Ultimately, a model’s intended purpose—speed, hauling capacity, or general commuting—shapes how much fuel it burns day to day.
