Is there any difference in the engines between a 2014 350 F Sport vs. 2016/2017 GS 350 base model? Is the F Sport engine tuned differently?
Thanks.

The biggest difference would be the 6-speed automatic vs the 8-speed automatic. The 8-speed delivers more MPG but the 6-speed is more responsive (and faster 0-60). There's also a minor 5HP difference. This is entirely the difference between the 2014 and 2017 models.

F-sport adds Sport+ mode which adjusts the springs and tightens up the steering wheel versus regular Sport mode which just makes the throttle and shift-points more responsive.

There is a difference, but it has nothing to do with the F Sport versus base models.

All 2013 - 2015 GS350s used the 2GR-FSE engine, rated at 306 hp.

All 2016+ GS350s use the 2GR-FKS engine, rated at 311 hp. The main difference here is the FKS has the ability to run in the Atkinson cycle during low load conditions, which may yield a small benefit in fuel mileage.

I doubt you'd notice a difference.

The transmissions between a 14 and a 16/17 are the same. 6 speed on AWD, 8 speed on RWD. The only year this was different was 2013, where both RWD and AWD used the 6 speed.

Thanks for the correction, for some reason I grouped 2013 and 2014 in my mind.

Theres no different in the engines of the same year between fsport and non fsport. The fsport will adjust steering tightness/shocks/throttle in sport+. You can get the throttle response as aggressive with a apexi accel.
