Turbo Gasoline0.55 - 0.60
Diesel0.35 - 0.40
Overview
BSFC measures engine fuel efficiency by calculating fuel consumed per unit of power produced. Lower BSFC means better efficiency. Essential for engine tuning, comparing engines, and estimating fuel needs.
💡
Pro Tips
A lower BSFC number means the engine is more efficient at turning fuel into power.
BSFC changes across the RPM range; engines usually have a 'sweet spot' with maximum efficiency.
Fun Fact
Did you know? Modern hybrid engines operating on the Atkinson cycle can achieve BSFC values similar to high-end diesels.
