Lotus has confirmed it will return to the Indycar racing series on 14 March at Sao Paolo, Brazil.
Although full details are yet to be confirmed, it is expected a Lotus-branded team will run two cars in the championship under the Team Lotus USA banner. They will be Dallara built and Honda powered.
Lotus entered the Indy 500 between 1963 and 1969 and won the American showpiece event with Jim Clark in 1965.
Currently Honda supplies the 3.5-litre V8 powerplants in Indycar, but Lotus is said to be considering a bid to takeover the supply when Honda's contract ends in 2011.
The Lotus Indycar team will have no links to the F1 project.
