FIA Single Seater Director Nikolas Tombazis has said ADUO is not a \u201cmagic bullet\u201d and \u201ca manufacturer will still need to make the best engine to win.\u201d<\/p>\n
Additional Development and Upgrade Opportunities (ADUO) relates to the ability of the five power unit suppliers to improve their product if it is found to be lagging behind the benchmark performer.<\/p>\n

It\u2019s not a magic bullet, or like the FIA is handing out brownie points to somebody who\u2019s behind, it simply provides them with leeway to develop their power unit within the framework laid out by the Technical Regulations.\u201d<\/p>\n More on ADUO from PlanetF1.com<\/p>\n What is ADUO? The FIA lifeline that could rescue Honda<\/a><\/p>\n FIA confirms major F1 2027 engine rules shift as electrical ratio revealed<\/a><\/p>\n Tombazis went on to detail just what the ADUO benefits will receive and pointed to the regulations which state the main benefit is monetary.<\/p>\n \u201cThe positive impact of ADUO on a manufacturer\u2019s expenditure is laid out in Article E4.1.1.t of the 2026 Formula 1 Regulations,\u201d he said. \u201cThe article defines the allowances granted for each ADUO period to manufacturers that falls 2% or more outside the performance of the best PU to support development activities outside its cost cap calculation.<\/p>\n \u201cSpecifically, every manufacturer from 2-4% behind will get allowances up to USD $3.0m. From 4-6% behind is up to USD $4.65m, from 6-8% is up to USD $6.35m, 8%-10% is up to USD $8m.<\/p>\n \u201cFor manufacturers having a deficit of 10% or more, in addition to an allowance for each ADUO period up to USD $11m, there\u2019s the additional possibility, for the season 2026 only, to anticipate up to USD $8m of Cost Cap of future periods to support development activities.\u201d<\/p>\n Want to be the first to know exclusive information from the F1 paddock?
