Difference between 13, 14, 15 ?
 

What are the main differences in the 2013,2014,2015 model GS 350 F SPORT?

Not a whole lot really. The 2014 got power mirrors and trunk. The 2015 got a better head unit and switched from the stupid SiriusXM system to HDradio for free traffic data. Us 2013 owners are sunk when it comes to upgrades on the head unit/technology, they basically left it behind in the product cycle.

Oh and the 2015 is the first year for RES+ on the GS. Most other models got it going back to 2013 or earlier. RES+ is the enhanced, internet-connected remote start stuff. Again making previous models look like red headed stepchildren that were deprecated. Sorry I sound butthurt but RES+ and HDRadio for traffic data should have been on the 2013 or a retrofit option. Power trunk and mirrors, whatever. :)

and the 14 &15 comes 8 speed.

Yep, the 8 speed also, but that doesn't apply to AWD models right? I think they still get the 6 speed.

Oh that makes sense I picked up 15 GS F Sport and I thought there was not that many big changes to the previous 13,14 models. So I'm going to be listening to HD Radio :D

Isn't there a change to double pane windows in there?

Which one is that :confused:

Yup AWD still has the 6 speed. 15 also brought along the moving guidelines with the backup camera

Yah it has the moving guidelines thats awesome! By any chance do you know if the backup camera pointer can be adjusted to be pointed a little outwards... because you can see the license plate when you put car in reverse is that normal or needs adjustment?

2015 they included double paned windows. They also changed head unit to microSD based (hidden behind Mark Levinson label). Dual USB ports in center console.

14/15 also have auto seat heat/cool feature.
so depending on what temperate you set, it adjusts the seat heater/cooler.

I learned that luxury package has had double pane since 13. I read double pane windows got added to 15 F Sports. Premium probably got it too since our 15 RX also comes with double pane. A new F badge was also added to the b*tt and the mouse pad is also new if I remember correctly.

Allen,
When did you get yours? How could I miss this? Congrats! That's one nice color combo. :thumbup:

Can you guys explain to me what does that double panes windows do/mean?
They are much thicker or what? I sound like a big noob :egads:

Two layers for better sound insulation. I don't really notice the sound on my single pane windows, but I guess some people do.

2014 and 15 have rear cross path detection. Also read that Lexus tweaked the exhaust in the 2014 vs 13.
