Volkswagen has the VW ID.4, an SUV that does not need gas to go for miles and miles. However, among gasoline-run Volkswagen vehicles, the VW Taos offers you the best fuel economy with an EPA-estimated MPG of 28/36 MPG (City/Highway)1 when you choose front-wheel drive, which comes with an eight-speed automatic transmission. You can also get this vehicle with the same 1.5-liter engine but with all-wheel drive. While this reduces the fuel economy somewhat, you'll still get 25/32 MPG (City/Highway)1.
