I have a feeling that this hybrid system will add a similar 200 lb ft of torque at the bottom end
and about 50 hp at the top as the incoming gearbox based RWD hybrids in Explorer/Aviator

That could mean the US GT will be around 500 hp/500 lb ft and the RHD version ~50 hp less.
Equally if added to the 2.3 Ecoboost, power and torque would become 370 hp/500 lb ft....

I wonder if the Americans keep this to themselves or share with others...
