SUVs or Standard Utility Vehicles are vehicles that offer a great compromise between comfort and utility typically at the expense of gas mileage. This is a great option for poor weather climates or those with a need to haul people.
Pickup trucks are almost strictly utility vehicles suffering from the same gas mileage issues. While they can be very comfortable, this is not their main purpose. There are options to accomodate 2-6 passengers while hauling cargo in the bed and the ability for towing
Cars will likely have the most range they can be as large or small, comfortable or uncomfortable, fast or slow, expensive or cheap as you want. There is always a model that can thrive under any conditions to meet any needs.
