The car is actually racing right now as I type this at the 24 Hours of Daytona. The reveal of the car was actually last year before the z4Gt3's final race at Spa. These images above are media release images for Daytona that were released earlier this past week, that being said, the car looks great. Just wait till you see what it looks like at night, the livery has reflective paint. Looks great.
Currently the M6 GTLM car #100 is 3rd in Class. 18 hours 40 minutes left of the race. Car #25 is 8th in class. Two Porsche cars in position 1 and 2 leading the GTLM class.
