Electric motors are in general, a lot more efficient that internal combustion engines. An average combustion engine has about 18â20%. A formula one engine, has about 50% of an efficiency.
Most larger RVs, as well as bus conversion RVs, run on diesel fuel. Diesel engines, designed for longer journeys and to take more stress, are also more fuel-efficient. For a price similar to gasoline, you can get several more miles per gallon as well as spend less on overall maintenance costs. However, for the most fuel-efficient RV, look into smaller models with diesel engines. For example, Winnebago makes a smaller motor home called a Rialta that is built on a Volkswagen diesel chassis. Smaller models plus diesel engines make for a surprisingly fuel-efficient motor home.
