My 2003 VW Golf has a gas gauge that shows percentages - the individual markings represent 12.5%, not individual remaining gallons (it's a 14.5 gallon tank, not an 8 gallon one) My mother's 2009 Jetta has similar. Whether or not the instrument cluster implements a multi-function display that shows instant/average MPG or miles to empty, every car I have ever driven, from the 80s clunkers of my youth to brand shiny new rentals has had such a fuel gauge. Such a style is cheaper to implement. Resistive float sensor in the tank, run a wire to a mini 90 degree needle gauge in the instrument cluster, done. Instant/Average MPG and miles to empty are additional fanciness that up until recently, came standard only on higher-end cars, or was part of an optional package that may or may not be avail on lower end brands/models.
