Simucube 2 has number of differences, starting from the base concept how it's designed and built, and how it integrates to everything. Two full years of precision engineering put into the development to bring racing simulator, steering wheel, rig, and realism as close together as possible.
Every part in SC2 has been tightly matched and optimized for each other - motor, angle sensor, electronics, firmware, signal processing, and even the power supplies. This allows Simucube developer team to stretch SC2 performance to the next level in terms of response speed, dynamic range and the realism of signal processing.
SC2 internal electronics have been completely redesigned for Direct Drive operation. New dual CPU architecture has plenty of headroom to be future proof in Sim Racing.
