Flex-Fuel Vehicle (E85)
A flex-fuel vehicle can run on petrol, high-ethanol fuel such as E85, or any mixture of them.
What is Flex-Fuel Vehicle (E85)?
Brazil and Sweden have many flex-fuel cars. Sensors detect the ethanol content and adjust injection. Range on E85 is shorter because ethanol has less energy. Ethanol absorbs water, so flex-fuel systems use materials resistant to corrosion.
How it works
The engine management changes fuel quantity and timing based on the measured ethanol share.
Why it matters for your car
Normal petrol cars must not use E85 unless converted and approved. Cold starts can be harder on high ethanol blends.
