According to The Car Connection, the IS500 will probably receive the 4.6-liter V8 from the new Lexus LS460 (wouldn't that make it an IS460?), which would up the power to around 380 horsepower.

When it comes to driving the 2024 Lexus IS500 F Sport Performance, though, there’s a finality to every rip, growl, and purr emanating from the exhaust of its naturally aspirated, 5.0-liter V-8.

Not as hot a take: This V8 variant—officially known as the 2022 Lexus IS500 F Sport Performance—should’ve happened, like, a decade ago. And it definitely could have come out then.
