Cars - Hyundai i30 N 2020 - Transmission & Speedometer issue

I can confirm that the in-car speedometer is animated as if it’s reading MPH regardless of what speed unit you are actually using.

As for the transmission issue, this is not the first car in the franchise to have a gearbox discrepancy between the car as modeled, and how it actually behaves in-game. The BMW M235i from Forza Motorsport 6 and Horizon 3 is modelled on an example with the 8AT, but behaves in-game as if it had the 6MT.

The obvious solution to this issue that PGG can perform from the backend would be to straight up copy the transmission, clutch, and shifting behavior from the Kona N, which is fitted with the EXACT SAME 8-speed DCT, though I’m not sure if they’ll do this as copying over the Kona N’s transmission coding wholesale may result in the base PI being altered.
