The ratings for Amazon Prime in the NASCAR Cup Series race at Pocono are out. The race was moved up two hours from its original start time due to weather, which may have impacted viewership.

According to a report from Chris Knight of CatchFence, the race drew an average of 1.66 million viewers. That was down 11% from last year’s comparable race at Pocono. Peak viewership, though, reached 2.30 million viewers, which topped last year’s peak by 6%.

And despite the year-over-year dip at Pocono, the NASCAR numbers overall on Amazon Prime have been quite strong so far this season. Through the first four races on the streamer, average viewership is 2.29 million, which is up 5% from the comparable four-race average on Amazon Prime a year ago.

One other interesting note? Amazon Prime reports that its NASCAR on Prime is averaging a median age of 57.9, more than five years younger than the audiences watching the Cup Series on linear channels this season.

Meanwhile, the pre- and post-race shows continue to post strong viewership. Through the first four broadcasts, pre-race viewership is up 2% vs. last year and post-race viewership is up 13%.

Overall, it’s been a mixed bag for NASCAR viewership this season. There’s no real discernible up or down trend, with the year-over-year comps varying weekly.
