These Cars Are Thought To Be The Worst Of All Time

Oldsmobile Cutlass Supreme Diesel (1979)

Diesel engines can be a great fix to many of our growing energy problems. They are more efficient than regular engines with few drawbacks. However, a poorly designed diesel engine can also be a major problem. The 1979 Oldsmobile Cutlass Supreme Diesel had a diesel engine that introduced a lot of performance problems. The engine was unreliable at best and had issues with fuel consumption. Many experts credit the downfall of the American diesel engine market to the extremely poor performance of the diesel engines in the Cutlass Supreme. One benefit from the Oldsmobile Cutlass Supreme is the engine blocks. They were made so well and so sturdy that race car drivers continue to use them today.
