What are Hypermilers? Hypermilers are drivers who exceed the manufacturer’s stated efficiency of their vehicles by modifying their driving habits and techniques. Hypermiling is a great way to save on fuel costs and drive more safely.
Where did the word Hypermiler / Hypermiling come from? The word Hypermiling originates from hybrid vehicle driving clubs, where people began to compare the fuel efficiency of their engines. The term was originally coined by Wayne Gerdes, who is considered by many in the hypermiling community as the “father of hypermiling.” The term has been officially recognised by the New Oxford American Dictionary and was their Word of the Year in 2008. With fuel prices continuing to rise in 2026, hypermiling is more relevant and important than ever.
How much of an increase in MPG would a Hypermiler get? Some hypermilers have reported MPG gains of over 60%, however expected gains will differ from car to car and depend on the technique used.
Do I need to modify my car to Hypermile? Hypermiling can be performed in any vehicle, but certain techniques are better suited to certain vehicles. See our Techniques page for more information.
What are the advantages of Hypermiling? Hypermiling not only increases your MPG — saving you money at the pumps — but it also reduces wear and tear on components such as brake pads and discs, due to smoother acceleration and braking. Results will vary depending on the technique used.
How can I check my MPG? Modern cars increasingly offer fuel consumption (MPG) displays as standard or as an optional extra. It is also possible to fit an aftermarket gauge such as a ScanGauge, which not only shows MPG but can also be used to diagnose your car and display up to 12 other useful readings. Please note that you will need an OBD-II port on your car. Alternatively, use our MPG Calculator — simply enter the litres used and distance travelled to calculate your MPG quickly and easily.
What is the best vehicle for Hypermiling? You can hypermile in any car, but the best results are often seen in hybrid vehicles such as the Toyota Prius, Honda Insight, and Honda Civic Hybrid, as well as modern plug-in hybrids (PHEVs) and electric vehicles (EVs). Hybrids are particularly well-suited as they have a secondary electric power source that can be leveraged for greater efficiency.
What is Nempimania? Nempimania is an obsession with achieving the best possible fuel economy. The word is derived from the Japanese nempi — a contraction of nenryōshōhiryō, meaning fuel economy — and mania, meaning a craze or passion.
What is a Hybrid? Hybrid cars combine a conventional petrol (or diesel) engine with an electric motor and battery system. The on-board computer decides when to use the engine, the electric motor, or a combination of both to maximise efficiency. For example, a hybrid may use the electric motor at low speeds or when pulling away, then switch to the combustion engine when more power is required. Modern hybrids also include PHEVs (Plug-in Hybrid Electric Vehicles), which can be charged externally for extended electric-only range.
