Lexus IS trim comparison
2025 Lexus IS 300 vs 500 F SPORT Performance Premium
The IS 300 starts at $40,535 while the 500 F SPORT Performance Premium is $64,020. That $23,485 gap buys 7 meaningful differences.
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.
Start with the 300 if the 2.0L I4 Turbo already feels sufficient for the way you drive. Step up to the 500 F SPORT Performance Premium only when the 5.0L V8 powertrain is the reason you are moving higher in the lineup.
If you are budgeting this move monthly, the jump from the 300 to the 500 F SPORT Performance Premium is about $413/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $24,780 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
