American media outlets are reporting that Ford is secretly working on an EcoBoost version of its new Coyote V8.

Although speculation at this stage is a twin-turbo 5.0-litre V8 packing at least 400kW, it could be just what FPV is after to stuff under the bonnet of its much-rumoured GT-HO revival.

While we must stress at this point there have been no whispers from FPV's Broadmeadows HQ, the scuttlebutt from Detroit is different. Online publication The Detroit Bureau is reporting that the twin-turbo EcoBoost V8 could be readied to slot under the bonnet of the Shelby GT Mustang.

Ford has already confirmed an EcoBoost V6 in addition to the inline four-cylinder powerplant Ford Australia will use in the Falcon.

Given that the current supercharged 5.4-litre V8, originally developed for the Ford GT and now used in the Shelby, produces 400kW (540hp) don't expect anything less from the EcoBoost version.

The benefits for using the EcoBoost technology for direct injection and forced induction would have a major benefit on the fuel economy for the increasingly scorned current V8.

Such an engine would surely make an ideal candidate for a resurrected GT-HO, should the car ever move from daydream to reality.

This is all strictly from the rumourfile but as the saying goes, there's no smoke without fire...
