Will an extra 50 pounds in your car effect gas mileage?

Adding 50 pounds to your car will have a negligible effect on gas mileage. The Environmental Protection Agency (EPA) estimates that adding 100 pounds to a car will decrease its fuel efficiency by about 1%. So, adding 50 pounds would only decrease fuel efficiency by about 0.5%. This is because the weight of the car makes up a very small proportion of the total weight of the vehicle and its occupants. The EPA estimates that the average American car weighs about 4,000 pounds, and the average weight of a human is about 150 pounds. So, adding 50 pounds to a car with four occupants would only increase the total weight of the vehicle by about 1.25%.

On average, a 100-pound increase in the mass of a car drops fuel efficiency by about 1%-2%, depending on the car and its aerodynamics. Therefore, 50 pounds would reduce gas mileage by less than 1%.

However, if you are carrying around a lot of extra weight in your car on a regular basis, it could eventually add up and reduce your fuel efficiency by a noticeable amount. For example, if you add 100 pounds to your car and drive 10,000 miles in a year, you will use about 100 more gallons of gas than you would if you didn't have the extra weight. This could cost you an extra $100 or more per year in gas money.

The weight of your car also has an impact on its performance. A car that weighs more will be slower to accelerate, slower to stop, and will have a longer stopping distance. So, if you are concerned about safety, you should avoid adding too much extra weight to your car.
