The 1990 model year saw the high-MPG field tighten, as gas mileage ceased to be the priority it was in the early years of the previous decade. While half of the top ten highest-MPG cars in 1990 carried a domestic nameplate, those choices were all imports. GM grabbed the top honors with the fuel-sipping three-cylinder Geo Metro XFI, a rebadged Suzuki Swift. (In fact, all of GM’s highest mileage offerings in 1990 were manufactured by Suzuki.) The Chevy Cavalier struggled to break the 35 MPG highway mark. On the other side of the domestic fence, just one model of the domestic Ford Escort broke the 40 MPG highway mark, as did the imported Ford Festiva. The two-seater Honda Civic CRX HF continued to produce respectable results, with a 52 MPG highway mark. The Jetta remained as Volkswagen’s sole compact diesel.
