Track Time! What is this symbol on the bottom of Hot Wheels? 14A Track Time by Race Grooves

Track Time with models from late July, 2013! These have a base code of F30 which means that they were produced during the 30th week of 2013. From a Hot Wheels 2014 A case.
Just like real car manufacturers, Mattel starts the yearly collections in the previous year. As you can tell by this case code and production code, they started manufacturing the 2014 assortment the last week of July, 2013.

Race Grooves Track Time videos test various models on different track layouts. It may be Hot Wheels boosters, loops and curves. It might be a gravity drop layout. It might be downhill racing. It might be a track layout with kicker launchers. From these reviews, we learn which cars work better on different Hot Wheels track system parts.
From time to time, I give tips on which cars perform better. You'll find occasional explanations as to why I think a car is not successful. I may also give tips on how to improve your Hot Wheels Track System layouts. Of course, you might see me teaching how to "pinch and flare" as well as show what events cause track sections to start separating.
Due to my concerns with COPPA interpretation, Track Time shout-outs are discontinued. I will be re-editing (and removing) older Track Time presentations on my Race Grooves channel and re-uploading them here on the official Track Time Channel to reflect the current UA-cam environment.
