Just got my 2024 350h few minutes ago. During tutorial, i asked if 350h requires regular gas, and if premium gas is only recommended, the dealer told me it only requires regular gas b/c it does not have turbo.
I always thought all 350h comes with 2.4L turbo, or is it just a 2024 thing?
Anyway, i prefer non-turbo over turbo for the longevity of the engine, my driving style is very calm.

The nx350 is a turbo the nx350h is not. Google there brochure and it gives a breakdown.

The 2.5L A25A-FXS engine in the 350h "recommends" premium because it is a high compression engine, but is tuned to accept regular fuel by sacrificing top end performance. If your style is calm, you'll never notice the difference, stick with regular. The T24A turbo engine in the 350 is meant to be a lower emission replacement for the 3.5L 2GR V6 engines which have traditionally inhabited the mid-upper performance tier in Toyota land. It is detuned in Toyota vehicles to accept regular as well, but so far Lexus has kept the higher performance tuning and thus, premium is required.

These engine options have not changed since the 2nd gen NX came out for 2022 MY.

And for sake of completeness, the NX250 uses the A25A-FKS engine, this engine there is zero benefit using premium, it is completely tuned for regular.
