There are 61 cars registered in this weekend’s Rolex 24 – the largest field for almost a decade – including seven in the Prototype category, 10 in LMP2, nine in the LMP3 category, 13 in GTD Pro and 22 in GTD.
You will notice one name missing from this list: GT Le Mans. Yeah, this class is now gone while the GT class combined into two categories. This class is busy this season and will occupy more than half of the field this weekend.
Wayne Taylor’s #10 Acura will lead the 61 cars to green on Saturday (1:40 p.m.) after winning last weekend’s qualifying race in thrilling fashion, fending off a late charge from the #5 Cadillac DPi machine, driven by Richard Westbrook.
