From what I see of comparable-model cars, efficiency gains in engines, aerodynamics, etc. have mostly been offset by safety, emissions, and QoL improvements that have increased weight. For instance, by spec, the most fuel-efficient Corolla was a 1984 model.

Do note the note at the bottom of the table: "Note: the EPA tweaked their testing procedure, starting with the 2008 model year, with the end result being that the 2008 MPG estimates are now lower than previous years" Other compact cars have followed a similar trend where they've gotten much heavier and safer, but fuel economy (in terms of fuel per distance) peaked or stagnated.
