IndyCar engines will reduce from 2.4-litre to 2.2 for the introduction of new regulations in 2012.
Honda, Chevrolet and Lotus have all committed to supplying engines for the next generation rules coming into force next year, and the INDYCAR Engine Committee has announced a reduction in capacity.
Series boss Brian Barnhart said: "One of our goals with the new engine was to challenge the automotive industry to balance power, efficiency and durability.
"As we've progressed defining our engine rules with the INDYCAR Engine Committee, we felt it necessary to reduce displacement to a maximum of 2.2 liter to be in line with our smaller, lighter and more efficient direction."
The 2012 units will be six-cylinder and turbocharged, producing between 550 and 700bhp. They will all run on E85 flexible fuel (85 per cent ethanol).
