Didn't realize Lexus made a luxury performance sedan with a NA 5.0L V8: https://www.lexus.com/models/GSF/specifications
Looks like Ford is not the only auto maker that favors a higher revving mid-sized V8.

Pretty even match up in power to weight between the 2018 GT's and the RC F or GS F versions. 5.0L vs. 5.0L. Lexus has a 12.3:1 compression, Ford is running 12.0:1, both are DI. Lexus peak power is at 7,100 RPM, not sure of the rev limit or if it has that massive flat top power band of the 3rd gen 5.0.
But I think the 2018 GT has a significant power band advantage especially if you compare Auto to Auto. But a Power Pack 3 2015-2017 GT would be a really good match-up for the GS / RC F. Both are RWD sport sedans. Lexus is in the 3,800 lbs range, the Mustang if optioned lightly is in the 3,780 lbs range, pretty comparable. But you could buy almost 3 mustangs for the cost of just a single GS F...
