The main task for my Cybertruck will be to tow house segments from the construction hall to the building ground.

The main problem for range is here air resistance. The typical speed will be 90 km/h.

When the drag = 1, this would mean:

25 m/sec * 10 m² area * 1.3 kg (1 m³ air) * 25²/2 * cw 1 = 101 kW.

Assuming 1% rolling resistance, Cybertruck loaded to 3500 kg, trailer 3500 kg

25 m/sec * 0.01 rolling resistance * 7000 kg * 9.81 m/sec² gravity = 17 kW.

So something mounted on the Cybertruck for aerodynamic optimization could drastic increase range.

118 kW, half of this is 59 kW. So bringing down cw to 0.4 would double the range. Any ideas and solutions welcomed.
