Although it is an old article (2002) it is interesting to see how Ecomodders are discussing many of the same topics today that were used on this car. Perhaps many newer members like me were not even aware of this car. Its specially made one-cylinder diesel engine produces 8.5 hp but is still able to power the car to 120 mph. Some of its features: LCD rear view, cooling slots that only open when needed, enclosed rear wheel wells, ...and its beautiful, too!
