UPDATE:Like nearly everyone else in the garage area, William Byron is not completely sure what to expect when the NASCAR Cup Series heads back to Martinsville Speedway in October for the Xfinity 500.
The past couple of days have seen Byron and several other drivers make laps around the historic half-mile in a test session that saw teams experiment with a different tire compound and gear ratio ahead of the penultimate race of the season.
Byron was encouraged by what he saw out of the tires on Wednesday afternoon but admitted there is not yet enough information for him to infer on how different the Xfinity 500 will be compared to the Blue Emu Maximum Pain Relief 400 in the spring, which he ended up winning.
Corey LaJoie set the fastest time in the Wednesday test session with a 20.021. Ryan Blaney was second overall and was followed by Denny Hamlin, Byron and the Petty GMS No. 43 that was split between Erik Jones and Noah Gragson.
