Did you know the most fuel-efficient cars ever sold in the US aren’t all hybrids or EVs? Some old-school gas rides like the 2016 Prius Eco and the OG Honda Insight absolutely crushed it, getting up to 58 mpg! Even the humble Geo Metro XFi from the '90s was a hypermiling legend. If you thought you needed a plug to save at the pump, think again—these gas-only cars were ahead of their time! #Cars #BuyingCar #CarFacts
