It is an S4S. Two key indicators are the S4S sticker and the deep dish wheels. The motor sound was dubbed in and it's not a 4cyl. Ford would have used a new V8 if they could get their hands on one and Lotus factory would not let them use one for Ford's marketing purposes. This car 300hp stock goes 0-60 in 4.7 and 168 top end. The new V8 350hp (can be modded to 550 with a new chip) goes 4.1 and 173.
