# Government notifies E100 flex-fuel registration rules ahead of car launches 2026-10-26T09:12:43+00:00 | Governance | Indian Opinion Desk Corroboration: 4 independent outlets (5 source reports) The Centre on Monday (26 October) amended the Central Motor Vehicles Rules, 1989, to allow flex-fuel vehicles that run on petrol blended with up to 100% ethanol (E100). The notification, dated 23 October, adds E100 alongside E85 in emission provisions and updates fuel specifications and testing requirements. Officials said the move comes months before carmakers are expected to launch E100 models. The government clarified that E85 and E100 may be used only in vehicles specially designed and certified by original equipment manufacturers as flex-fuel vehicles. Vehicles running on E20 or conventional petrol cannot use the higher blends, and owners of existing vehicles are not required to switch or modify them. Officials said ethanol has a lower fossil carbon footprint than conventional petrol and that greater ethanol use would cut tailpipe emissions and reduce dependence on crude oil imports. ## Indian Opinion Analysis All four outlets report the same government notification verbatim, with near-identical text. The only material difference is that BusinessLine adds context: it notes that the Petroleum Ministry in July said no decision had been taken to raise the nationwide base blend beyond 20%, and that Maruti Suzuki in June had to certify its flex-fuel car under the older E85 rules because E100 was not yet recognised. This context is absent from the other three sources, which confine themselves to the official announcement and its advantages. The uniform core text means no framing conflict exists among the outlets, the extra background from BusinessLine gives its readers a clearer picture of how the rule change closes a regulatory gap that the industry had flagged. The notification took effect on the date of its publication in the Official Gazette, 23 October 2026. ## Coverage Coverage: 3 sources, 3 neutral - Syndicated copy - timesofindia.indiatimes.com Straight wire copy of government announcement, no added context or critique - economictimes.indiatimes.com Straight wire copy of government announcement, no added context or critique - cnbctv18.com (neutral report) Straight wire copy of government announcement, no added context or critique - thehindubusinessline.com (neutral report) Adds industry context and Petroleum Ministry clarification absent from other sources This brief was synthesised by AI from the 3 sources linked above, so one read covers every framing they carry.
