What are the challenges of a flex-fuel car?
A flex-fuel car also faces some challenges in the Indian market, such as:
- It requires a compatible engine and fuel system that can handle different ethanol blends and prevent corrosion, leakage, or performance issues.
- It requires a reliable supply of ethanol and a well-developed distribution network that can ensure availability and quality of the fuel.
- It requires consumer awareness and acceptance of the new technology and its benefits.
