It's almost a given for the time being that even exhaust scrubbers which attempt to salvage unburnt gasses from the exhaust (beyond what already exists) just aren't worth the production costs weighed against the gains they could see. Short of an afterburner (which, on a car, would do next to nothing), there isn't much capability to reburn those gasses and get any energy benefit from it.
