Trying to make an IDI Diesel comply to current emission standards would be a PITA, but they're often pointed as less energy-intensive (thus cheaper) to manufacture. Another aspect to consider is their ability to run on vegetable oils, which may be the least energy-expensive among viable vehicle fuels and can be supplied from a wide range of feedstocks. Considering the energy-efficiency increase in the vehicle manufacturing and fuel supplies, it's already somehow advantageous over hybrids.
