Whatever Lexus sticks an F badge on should be good enough for the Fuji Speedway, and the GS F packs a naturally-aspirated 5.0 V8 with an almost instantly available 467 horsepower to justify its name. Is that enough? Well, on today's market, not for everybody.
The GS F is very heavy to begin with, and its outdated automatic gearbox makes it feel even more sluggish when you really put your foot down. The distinctive styling can raise a few eyebrows as well, and while the build quality is as good as it gets, the infotainment system is useless. The sum of all that is not positive despite the V8's glorious soundtrack, which means buyers might not be swayed to choose this slightly old-fashioned performance sedan over Germany's latest and greatest.
On the side, the GS F will be an absolute steal in 15 years. By then, it will be just an old performance sedan with a gearbox that feels period correct and digital functions that your phone will accomplish ten times better anyway. But due to way Lexus puts its cars together, most features will work, and that N/A V8 will still make at least 430 horses worth of noise. Just wait for it and hope that enough people buy them today, filling up the second-hand market nicely for you by 2032.
