Lexus first offered fans a look at the new car in August last year, before the regular RC had even been revealed.
While that orange and black beast had kept a number of key styling details covered up, this new white racer wears a look much closer to its production RC F inspiration.
Full details on the new race car are still to be released, but expect a regulation 2.0 litre turbo engine to provide motivation - a change from the 3.4 litre V8 engines previously used in the series.
Elsewhere in motorsport, Lexus has revealed it will also send a powered-up experimental LFA supercar to this year’s Nurburgring 24 Hour endurance race.
Dubbed LFA-X, the new car has been developed specifically to test future motorsport technology under race conditions.
As part of the program, the LFA-X has had the capacity of the ‘regular’ LFA’s 4.8 litre V10 engine increased to 5.3 litres.
Lexus says it has “fine-tuned” output and torque from the enlarged engine, although specific figures were not offered.
