CTU.24

The all-electric single-seater with autonomous driving capability, named CTU.24, was the first car created by the newly merged team.

The concept of this car took a completely new course compared to the past years of the two previous teams, focusing not only on autonomous systems, but also on serviceability, reliability, ease of handling, and to serve as a base for future seasons as well.

It is powered by 4 electric motors built into the wheels, each capable of 36 kW of power. The aerodynamic package is entirely new and features new layups for the composite parts.

The newly formed eForce Prague Formula team started a new common future with this single-seater. It had the chance to prove that it was competitive on a global level even against the best teams. The joint journey thus began with one of the most successful seasons in the teams’ 16-year history.
