FOS is an abbreviation for Festival of Speed, the annual motorsports gathering at the Goodwood estate in England, from July 4-7. Ford Performance's Hermann Salenbauch and Multimatic's Larry Holt will make the special Ford GT announcement. Ford is coy about the announcement with no details on what it will talk about other than the lone teaser image you see here.
The study of the hypercar rules is part of a wider evaluation undertaken by Ford into its future in what it is calling "electrified motorsport" - raising the prospect that the auto to be unveiled at Goodwood incorporates hybrid technology. The silhouette also shows a larger roof-mounted air intake than we have seen.
Hermann Salenbauch will be accompanied by the chief technical officer of Multimatic - the firm responsible for actually building the vehicle - which suggests that Ford is poised to deliver news of a production model rather than an addition to its race programme, given the manufacturer has already confirmed withdrawal of its support for the GTE-Pro class after a four-year campaign.
Ford had promised the Mustang Shelby GT500 would be its most powerful factory-built auto ever.
Ford ran these heritage liveries at the 24 Hours of Le Mans just last weekend.
Gymkhana TEN star Ken Block's Hoonitruck and Escort RS Cosworth will also take on the iconic 1.16-mile hill climb. The Ranger Raptor truck will demonstrate its capability in an off-road experience.
