How much does weight reduce gas mileage?
An extra 100 pounds in your vehicle could reduce your MPG by about 1%. The reduction is based on the percentage of extra weight relative to the vehicle’s weight and affects smaller vehicles more than larger ones.
How does weight affect the fuel economy of a car?
Fuel economy can be improved without sacrificing safety. Various technologies can raise fuel efficiency without reducing the vehicle’s weight. Manufacturers can also improve fleetwide fuel economy by taking a small amount of weight off their heaviest vehicles without significant safety tradeoffs.
What’s the difference between vehicle size and weight?
That puts less force on the people inside the heavier vehicle and more on the people in the lighter vehicle. IIHS demonstrated the role of size and weight in a series of crash tests in 2019, pairing a midsize SUV and small car made by Kia and a large car and minicar made by Toyota in collisions with each other.
How to find out how much your car weighs?

What happens when the size of a vehicle increases?
As the chart below illustrates, crash deaths decline as vehicle size increases. A similar chart using weight instead of size would look almost the same. A lighter vehicle will always be at a disadvantage in a collision with a heavier vehicle.
Why is weight more important than horsepower in a car?
In his latest video, Road & Track contributor Jason Fenske of Engineering Explained breaks down how horsepower and weight affect each other, and why a car’s curb weight is the most important factor in determining performance and fun. The thing to keep in mind is that horsepower is heavy.
