This is the 3rd release on Tamiya's RC High Performance TB-04 chassis platform. The model depicts the RAYBRIG NSX CONCEPT-GT, a car developed by Honda to race in the 2014 Japanese Super GT Series. The hi-tech race car features a 1.6-liter turbocharged direct injection engine with anti-lag, plus a mid-ship layout that optimizes distribution of the car's weight, particularly taking into account its unique hybrid system.

The TB-04 is a 1/10 scale 4WD machine that incorporates a drive-shaft down the center of the chassis to engage the front and rear gearboxes. The differentials inside the gearboxes are newly designed as they utilize a sealed gear differential system whereby the internal gears movement is controlled by different viscosity differential fluids. The double-wishbone suspension system utilizes the same "short reversible" type that has been used on the TB-03, TA-05 Version II, TA-06 and the TRF (Tamiya Racing Factory) 416 and 417 World Championship machines. The TB-04 also incorporates "IFS" (inboard front suspension) whereby the front shocks are positioned horizontally and low to the chassis, so that low profile sports car body shapes can be accurately reproduced without losing any realistic scale appearance.
