Four surface and underbody active aerodynamic components work in harmony to manipulate airflow giving The C_Two unmatched aero performance and enhanced efficiency. <\/h3>\n\n\n\n

Everything from the active front splitter and intelligent underbody air flaps to the adaptable air brake is designed, developed and tested to perfection in-house, the Rimac way.  <\/p>\n\n\n\n\n\n

        C_Two aerodynamic profile variations:<\/h4>\n\n\n\n
        • In Range Mode drag is reduced by 17.5% when compared to the Track Mode. <\/li>
        • Shifting from Range to Track Mode increases downforce by 326% <\/li>
        • High speed configuration (DRS) reduces drag coefficient by 10%  while keeping balanced downforce. <\/li>
        • The fully extended rear wing increases rear radiator mass flow by 7.7% <\/li><\/ul>\n\n\n\n
          \"\"<\/figure>\n\n\n\n

          C_Two has the largest differentiation on drag and downforce coefficients which means it\u2019s able to meet Range and Track performance targets with a simple driving mode change.<\/p>\n\n\n\n\n
