Diesel aftertreatment systems are still cheaper to manufacture than a hybrid driveline, altough they're really a few times more trouble-prone

Actually, taking into account the higher fuel consumption, the requirement for the DEF and all the footprint of an enhancement in oil drilling, refining and its logistics until it reaches the refuelling station, and also all the production chain of the DEF, it makes me quite skeptical about the effectiveness of those aftertreatment systems...
