Is the limited space of the Supro Ambulance made up for by its fuel efficiency?

In a country as vast and diverse as India, emergency vehicles need to be fuel efficient. With a smaller engine, the Mahindra Supro Ambulance has better fuel economy than other larger ambulance. Lower operating costs may translate into bigger coverage areas even in rural ones where fuel stations are located far away apart. But at the expense of interior space, which some say is necessary for patient care and for carrying necessary medical equipment. Whether the trade off is worth it there is some debate. Is the ability to respond to more calls or service a greater area greater than the constraints in space and equipment? Others say that in urban areas with a lot of traffic, the fuel efficiency may not be as important as being able to carry advanced life support equipment. But others say the fuel efficiency could be a game changer in rural settings, where distances are greater and resources are scarcer. The issue this question elicits is the more fundamental issue of emergency vehicle design for particular environments as well as the tension between operational efficiency and medical capability.
