Saw the presentation...
but what about the Lupo having a top speed of 266 km/h? Even with near perfect streamline, that would require about 150 hp / 115 kW or so?
The power needed to reach a certain speed is a 3rd power function of that speed. Doubling the speed requires 8 times as much power.

I mean, the original 3L has a top speed of 165 km/h. It would need over 4 times as much power to reach 266 km/h, and different gearing, tires, etc.
The Lupo GTI is more than twice as powerful as the 3L and still barely touches 200 km/h...
If you can achieve the same speed from the 3L with all the aero work, that would be an accomplishment.
Claiming it can do 266 km/h may raise doubt about the truthfulness of the whole project and distracts from the goal you are trying to achieve.
I would not post that speed even if it were true and proven, just for that.
