I chatted about this to a Kia dealer in the UK actually, I was never considering buying the GT version, however, it came up in conversation and that YouTube video drag race, all very impressive. I was told this.... The Kia EV6 GT has an On The Road Price (OTR) of £58,295... in the UK, I am not sure how much of this is true, however, it makes it MUCH cheaper than most standard BMW EVs, even the fat Audi Etron fully loaded Vorsprung which is £94,000+ and only has 496 horsepower vs Kia EV6 GT 577 BHP. Seems cheap for what it is, some people have paid well over £50k for the GT Line S version.... As I say, not sure how much of this pricing is true.
A quick google also seems to confirm this, an example
