Lexus IS trim comparison

2024 Lexus IS 300 vs 500 F SPORT Performance

The IS 300 starts at $40,085 while the 500 F SPORT Performance is $58,870. That $18,785 gap buys 7 meaningful differences.

The short answer

This trim jump changes the engine from 2.0L I4 Turbo to 5.0L V8. Everything else is secondary to whether that powertrain difference matters for how you drive.

If you would notice the 5.0L V8 every week, the 500 F SPORT Performance makes sense. If not, the 300 is the cleaner stop because this jump matters for the powertrain first and the trim badge second.

Think about this as a monthly tradeoff, not just a sticker gap. The 500 F SPORT Performance adds about $331/month on a typical 60-month loan, or around $19,860 more overall with interest. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
