IPA: //ˈhaɪpərˌmaɪlɪŋ//
KK: /ˈhaɪpərˌmaɪlɪŋ/
The practice of driving in a way that increases a vehicle's fuel efficiency, often by using techniques like driving slowly and coasting.
Many drivers are adopting hypermiling techniques to save money on gas.
Hypermiling is formed from "hyper-" (meaning over or beyond) and "miling" (derived from "mile", which refers to a unit of distance). The term describes the practice of extending the distance a vehicle can travel on a gallon of fuel, thus going beyond normal mileage efficiency.
Think of 'hyper-' meaning 'beyond' and 'mile' referring to distance — this helps you remember that hypermiling is about going beyond the usual distance on fuel.
