Work out hybrid fuel saving instantly with clear inputs, formula shown and shareable results.
Hybrid saving is the consumption difference times annual distance. Hybrids gain most in urban driving where regenerative braking recovers energy that would otherwise become heat, and gain almost nothing at steady motorway speed.
Hybrid saving
litres saved = (petrol - hybrid consumption) x distance / 100; payback = premium / annual saving
Stop-start urban driving. Regenerative braking recovers kinetic energy and the engine shuts off at rest, both of which are irrelevant on a motorway cruise.
Only if charged regularly. Uncharged, a PHEV carries battery weight without the benefit and can use more fuel than a conventional hybrid.
