MUNCLE MIKES COLLECTOR GUIDE
Audi RS e-tron GT — 2024 HTB81
White bodywork and white wheel faces give HTB81 a very different look from the dark e-trons. The black windows and lower body form a strong outline through the center of the car.

What to look for
The 2024 Green Speed card is numbered 4/10 and 36/250. Those numbers are also used for the green recolor, so they identify the slot in the series rather than the paint.

Variation Summary







Choosing one for your collection
Check the white roof and door panels for marks or discoloration. Photographing against a slightly darker background makes the body edges easier to judge.
Inspect both wheel faces: the white detailing is part of the combination worth preserving on an original loose car.
Collector questions
Does 36/250 identify the white finish on its own?
No. The green HTD38 uses the same collector number. Compare the body and wheels as well.
