These overlooked diesel models each had something special to offer when they first hit the road. Whether it was the long-range capability of a family sedan, the reliable torque of a compact SUV, or the surprising fuel economy in a luxury vehicle, these diesel-powered cars pushed the boundaries of efficiency in their way. While they may not be the first options that come to mind today, revisiting these diesel gems reveals a fascinating mix of style, performance, and economy that still holds up, making them a worthwhile consideration for those willing to look beyond the usual options.
