It's a shame that the MFA (Multi-Phase Adapter) isn't visible in the picture... There must be some kind of monstrous vortex swirling around inside the tank.
The maximum speed values for the G 5 have significantly worsened compared to its predecessors. The G 3 GTI with 85 kW had a stated top speed of 196 km/h, and the G 4 with 85 kW was rated at 195 km/h. In contrast, the G 5 with 85 kW is now only specified at 192 km/h, which is a consequence of its van-like high roof.
Looking at the top speed figures for the G5 TDI with 103 kW, which was initially stated as 203 km/h but later increased by VW to 205 km/h (the same value as the 96 kW G 4...), it all makes sense. Good examples of the G 3, like mine, could also reach a top speed of around 205 km/h with a good run. If the tuner couldn't increase the Vmax (as mentioned before, regarding the rated RPM at Vmax), then these values are somewhat plausible.
Furthermore, the maximum speed values of the current A3 are not comparable to those of the G 5, as the A3 has a flatter, more aerodynamic design, as evidenced by its maximum speed of 207 km/h with the same 103 kW engine.
