cost of speed delimiter..what’s included?
I wonder what they had to update/upgrade to get from 137 to 149mph other than, perhaps, software update?

Here in the US - Fed regulations require the manufacturer to set the speed limiter to the speed rating of the tires provided with that vehicle.
In answer to your question - "Option Z10" for the 2019 G63 does two things: (1) changes tire from H rating (130mph) to V-Rated (149mph) (2) Changes engine Speed Limiter coding to 149mph

This is my first mb vehicle, let alone amg. I’d assume that amg complimentary academy should come with the amg vehicle..if ford can do it for RS vehicles so should amg

For the 2020 G63 - yes - the factory tires are Performance Tires - to go All-Season and for more aggressive look - there are two different series from Nitto in 22's that will work - there are other threads that cover this direction.

FYI, My g63 is expected to arrive before June (placed order in aug’18). For Range Rover, if you order 22 inch wheels you get speed delimiter/higher top speed, every vehicle and car company is different. Porsche put summer tires in most of the vehicles especially 911s.
Also to clarify, Im not starting threads for the heck of it, I have speed delimiter option added to config. and needed input before the configuration locks...
appreciate the input though!

22” RG4 wheels only come with summer performance tires
hmm..I find it somewhat strange but believable
delimiter only is software update, evidently
It’s all good, thanks for the help !

your answer, so as from the sales guy, was a guess, not accurate.
It comes with Pirelli Scorpion Zero “all-season” “performance” tires.
See my note in the other thread.
