Diesel is also more expensive here too - ~10% by extra taxation. Annual taxation is also higher. Some people actually prefer how a TD drives - mega torque at low-mid revs - compared to a petrol. That tapped Mrs A's 2011 Prius does "move" in "PWR" mode
but it takes more "shove" on the go pedal at speed to keep up with traffic - which is where it loses out compared to Diesels.
