Not in @DAYTONA today but will be monitoring the Next Gen test remotely and sharing my initial observations below.
My understanding is that the test will run the 510hp engine config and the 1st set of runs will be with a 7-inch spoiler and later they will test with a 6-inch.

Much of the aero configuration today will be similar to what we saw at Charlotte with splitter stuffers, engine panel strakes, and diffuser skirts being employed. They are also running the half-height rub blocks today.

The transaxle that they are set to start the day with is an AA configuration and that means that they are picking the A gear cluster set and A ring and pinion set. There is an A, B, and C option for each one. They are using a 19:22 drop gear which results in a 3.68 ratio. 
The day will start with team test time at noon and then in a couple of hours they are planning to do a 10-lap group run on fresh tires.
That group drafting session should be kicking off pretty soon.
My early and rough estimate based on power, aero, and gear ratios is that I expect maybe 190-ish MPH at the most while drafting in a group.
