Things aren’t matching up. Take a look at Page 5 – https://www.kia.com/content/dam/kwcms/kme/uk/en/assets/vehicles/The_all-new_Sportage/Specification/Sportage_specification.pdf
It shows that the ‘4’ and GT Line S ONLY come in AWD. I.e. the complete opposite of what you can actually order on their website (for “regular”) customers.
When you look at the screen to select the model you want, The GT-Line S mild hybrid isn’t listed as AWD and the price is £38,445. The next choice down is the GT-Line S Full Hybrid and it’s price is £38,645. That’s only a difference of £200, which cannot be correct.
Therefore I’m 95% sure your order will be AWD and KIA have just accidentally missed ‘AWD’ of the screen where you select the model you want to buy.
