The ST moniker is a good idea. Ford has been using it in Europe for years. The Euro Focus ST170 is the same car as our Focus SVT.
SVT was always supposed to be a ford equivalent of BMW M or Mercedes AMG, but despite building great cars SVT vehicles have never truly competed with the former nameplates. Now with ST (Street Tuned) filling the need for mass-market sporty cars, SVT can build true world-class high performance vehicles.
About the engines - the 2.0 and 2.3 are new designs that will be used by Ford's subsidiaries as well. The 2.3 is already in use in the Mazda6 and will be used with the 2.0 in the Mazda3 as well.
