I love the GR-S hybrid but the 68L tank was a deal breaker for me, its an issue in all GCC spec Hybrid GR-S 300s.
The GX-R/VX/VX-R hybrid 300 get the aux tank for a total of 98L (still smaller than 110L of non hybrid - but good enough)
No one has been able to tell me why but im guessing some sort of technicality by GSO maybe?
I believe previously in Saudi, we only had the GR-S as diesel, not petrol, versus the other GCC countries with petrol option available. So the petrol GR-S hybrid was a nice, new option here, until I fueled it up for the first time
I drive once a month between Riyadh and Dammam, approximately 400km. With my 2013 camry, I would go to Dammam and reach midway driving back before I needed to refuel. With the GR-S hybrid, I can't make it one way without needing to refuel.
It's the same aux tank as the Non-hybrid, but Toyota kept the same smaller main tank in place; best guess I have is for weight reduction (~20lb/9kg). I'm just guessing though as I haven't dropped my tank to see if there is some HV cabling that have required the change.
Edit: corrected typo in red.
I hope it is only for weight reduction, and there is space for a larger 110L/29G main tank as the replacement. Do let us know if you end up exploring the tank, I believe it was your posts on deleting the 3rd row that were very interesting. For the time being, I put a rug over the folded down 3rd row so it kinda looks like a false floor.
I meant to ask why does the GCC spec GR-S hybrid get only single tank 68L but other GCC Spec hybrid LC get aux tank as well for total of 98L.
Surely some regional spec technicality, could it be related to weight? I don't see the same issue with AUS spec.
Saudi has this issue with LX700h as well, they only get 68L but other GCC countries get LX700h with Aux tank ( total 98L ).
I did a quick check on the LX700H in Saudi, their website is listing main and sub tanks for 98L total. This might be new, not sure.
The sales people at Toyota in Riyadh were confused when I crawled under the VX-R hybrid in the showroom to look at the tanks
I take comfort in the fact that the GCC GR-S hybrid and the USA LX700H are same fuel tank sizes, and possibly Australia's GR-S hybrid when it launches in two months. We will then have multiple markets building solutions for same/similar vehicles.
I read on the Land Cruiser Forum a detailed post from a US-based LC250 owner who successfully swapped his 68L tank with a single 110L tank.
I hope to only replace the main tank versus having to explore adding an aux tank. However, I am not an engineer nor an auto mechanic, so I will continue reading the different forums and groups in search of a solution.
All of this might simply be wishful thinking as I navigate the joys of a first gen product
and my first new car (always bought used).
