Part of my dealer experience was to provide a loaner while my car was in for service, sweet. They provided a 2016, Non-Fsport IS300 AWD, I was surprised in comparison to my 2017 F-sport IS300. The loaner with almost twice the mileage felt quicker and more responsive. After service my car felt more tame, more refined which isn't a bad thing but my Fsport didn't feel higher in performance after the comparison. I could be wrong, might totally be in my head. Is there something I should know?

It could be you're not used to the throttle mapping. I always find that cars I'm not used to feel quicker than they actually are. (I had an NX 300 loaner not long ago, and thought it felt pretty peppy, even though I know it's slower than my 2016 IS 300 AWD.)

Though I do wonder if the refresh has any effect on the throttle mapping.

You're most likely feeling the difference in ECU adaptation. The ECU will adapt and tune certain aspects of the car according to the driver's driving style. It's a loaner car with high miles. People aren't usually that nice to cars that aren't theirs, so I'm sure it's had a much rougher, more abused life than your personal car.

Your personal car is likely treated more gently and as a result, the ECU adapts to this style of driving giving you the more tame and refined feeling you're noticing. F-Sport has the advantage of the Adaptive Variable Suspension if I'm not mistaken. It's always working and adapting, even if you're not in S+ mode so your car is able to adjust more than the standard non F-Sport car.

Could be because of 2016 non fsport had a 6-speed.

vs.

Your 2017 Fsport had a 8-speed.

The pickup of the 6 speed is slightly quicker than the 8 speed. We have to 8 speed for fuel efficient nowadays.

Yeah the AWD has 6 speed where as the RWD has 8 speed.

Uh....if his was RWD, than he has the 4 pot turbo vs the 3L V6. The V6 is a far more responsive engine than the turbo.

HOMER350

He said he has an IS300 Fsport (not the 200T) and loaner was IS300 AWD. I take it his IS300 is therefore not AWD. They make both AWD and RWD for the IS300 each with transmission as specified above.

(right !?!? Or is the lexus site wrong...than just shoot me my bad . )

EZZ

The IS350 is the only RWD version of the V6. The Is300 is either an AWD V6 or RWD turbo.

HOMER350

Geez. Thanks for clarifying.

IS300 RWD is 2.0 turbo (idk how I missed that) AND theres a 200T.

Sorry to butt-in with inaccurate info!

Thanks, I was just reading about that. Knew there was a missing link where I lost track of the configurations.

OP says his car is a 2017 IS300 FSPORT.

2017 was the last year the IS300 was the AWD V6 - 6 speed

AVS is not available on the IS300, only the IS350.

The IS300 AWD V6 with the 6 speed is still available for 2018, and the 200t was renamed the IS300 RWD. So for 2018 we have the IS300 AWD (V6, 6 speed) and the IS300 RWD (turbo 4, 8 speed).

So the OP's 2017 IS300 AWD and the loaner 2016 IS300 AWD F Sport both have the V6 and 6 speed.
