With F3.5 V8 to become the support series for WEC from next season onward, the representatives of each series revealed the prospective calendar with a change from the earlier one.

The original release had the single-seater championship supporting WEC at Silverstone, Nurburgring, Spa-Francorchamps and in the flyaways in Bahrain, Mexico and Japan.

However, the latest announcement sees a change, with the Fuji round in Japan being dropped in favour of a race at Circuit of Americas - likewise in support of WEC.

The statement released stated: "In 2017, Formula V8 3.5 will share six weekends with the WEC championship, all of them being F1 tracks.

"In addition to the European rounds, there will be three intercontinental outings in Mexico, USA and Bahrain.

"The round in North America is the latest addition to the calendar, replacing the event that was originally scheduled at Fuji, to keep the championship cost at a reasonable level."
