Porsche IMSA GT3 Cup Challenge by Yokohama may be a mouthful to say out loud, but as a single-make driver's series, it has some of the best racing action you can find. John Hindhaugh, the golden-throated Radio Le Mans announcer, narrates this video recap of the 2013 series opener at Sebring last month.

If you've never watched a Cup Challenge race before, Hindhaugh lays out the classes — Gold, Platinum and Master's — and various rivalries that'll help you get the most out of the series. No more will you ask yourself, "what the hell am I watching," as you stuff yourself with Velveeta Ketchup Crackers.

Plus, Hindhaugh recaps the Sebring race's thrills, spills and crash-o-riffic chills, and flips, dips, chains and whips, a constant in GT3 Cup that makes the series more than just a glorified parade of million-dollar sports cars. It's all laid bare on Sebring's less-than-ideal track surface for your consideration.

Looks like it'll be a helluva year.
