Why do compact crossovers have small fuel tanks

903 viewsEngineeringOther

I’m curious as to why small crossovers have tiny fuel tanks. I’ve seen the Buick Envista and that vehicle is plenty big enough to accomodate a 15-16 gallon tank to enable it to go at least 600 miles if not more at the 32mpg interstate rating. Why do automakers keep putting 11-13 gallon tanks in vehicles that only allow it to go around 300 miles on a tank. Wouldn’t the bigger fuel tank be the better and more sensible option?

Companies do research into what consumers look for. Every click on their website for a car, how long people spend looking at each page. They look at what reviews say, they ask salespeople what buyers ask about, etc 

People buying compact cars likely want cargo space. Picture the size of a 5 gallon bucket, now take that away from the storage area.

A small tank costs less to fill than a large one. Even though math says there isn’t a difference in fuel economy not everyone is good at math. There may be some psychology that consumers think they are better off spending less to ‘fill up the tank’.
