DRe21 is a single-seat FSEC racing car jointly built by more than 100 members of TJU DIAN Racing. The new car combines the design of the past with many innovative elements. DRe21 adopts the carbon fiber monocoque body, supplemented by carbon fiber aerodynamics suite, which makes the total weight of the car reach 195kg, reducing the weight by 5% compared with the previous generation. In terms of the power, it adopts four-wheel independent hub motor, which can achieve an equivalent thrust-weight ratio of 450 HP/t under the power limit of 80kW as specified by rules, and can also complete dynamic torque transfer, drive the anti-skid and brake energy recovery under the control of the main control program. The decoupled suspension and multiple derivative design structure of the chassis also stand out.
