“On April 1, 2023, the company first calibrated vehicles for E10 and on April 1, 2025, for E20. Anything produced after April 1, 2025, is calibrated for E20,” he added.
Citing government regulations, he said in older vehicles which are already on the roads, calibration is not allowed. When asked what the impact of E20 fuel on the older vehicles will be, he said, there will definitely be a performance hit to that extent because it’s not calibrated.
“You will see either an acceleration degradation, or you could see a fuel efficiency degradation,” Gollagunta said.
