The FIA's World Motor Sport Council has approved a change to the F1's sporting regulations which will allow teams to use current-spec cars for demo runs at public events.
F1 has been restricted up to now from using their latest cars in special events such as London's F1 Live which took place in July before the British GP.
A current provision in the sporting rules permitting just a short, maximum 15 km run over the course of two days for current cars between the end of the season and the end of the calendar year is destined to cater to the needs of a championship winning team and its celebration agenda.
Teams usually conduct demo runs with old machinery, but next year they will be able to use 2018 cars in demo events organised by Formula 1's Commercial Rights Holder.
The 15 km limit will remain however, and the rules specify that "no such demonstrations may take place on track configurations currently approved for use by Formula 1 cars."
After London's popular F1 Live celebration around Trafalgar Square in July, F1 CEO Chase Carey said there would likely be more events of the sort in the future in major cities of countries hosting a Grand Prix.
