Hi Rebecca!
Thanks for visiting the Moms Panel with your question!
I was lucky enough to be at Walt Disney World just last week and experienced the newly re-imagined
Test Track Presented by Chevrolet! It's great fun!
The actual 'ride' component of the attraction remains very much the same as the former version, in terms of the physical track that your ride vehicle follows. I did find that the new vehicles seemed to move more smoothly along the track, and was happy to see that the 'blocks' and cobblestone roughness at the beginning of the track are no longer. Overall, the experience is much more futuristic with very modern effects and updates. Along the way, the track is more enclosed as you go through each section.
The big differences are in the queue, where you'll partake in an interactive experience before boarding your test vehicle. There's also new features to look at upon exiting the attraction. It's fantastic - and I'm sure you'll enjoy it thoroughly!
Wishing you a simply Magical time on your next Walt Disney World vacation Rebecca!
