Why do compact crossovers have small fuel tanks

901 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?

40L petrol tanks are normal here in the UK (and I assume Europe).

Why carry all that extra fuel around when you’re usually at most half hour drive from a pump.
