Abstract: The object of the present invention is a fuel composition comprising: (i) from 50 to 79% by mass of a mixture of hydrocarbons comprising: a) from 35 to 55% by mass of aromatic compounds; b) from 30 to 50% by mass of non-cyclic paraffins containing at least 5 carbon atoms; and c) from 5 to 15% by mass of naphthenes; (ii) from 20 to 40% by mass of one or more ethers; and (iii) from 1 to 10% by mass of butane. This composition is useful for supplying a controlled-ignition engine, in automobile vehicles intended for general-public applications or for competition.
