Before the 2021 Porsche Panamera debuted this week, Porsche set a new lap record at the Nurburgring for executive cars when the new Panamera Turbo S completed the challenging German circuit in just seven minutes and 29.81 seconds. This was only 0.3 seconds faster than the previous record-holder, the Mercedes-AMG GT 63 S, which posted a time of seven minutes and 30.11 seconds. But judging from a recent social media post, Mercedes-AMG could reclaim the crown from Porsche sooner rather than later.

In a video posted on Facebook this week, Mercedes-AMG published footage of the GT 63 S' previous lap Nurburgring lap record set back in 2018.

Accompanying the video is a caption issuing a clear warning to Porsche: "Our record lap was the best of its class and only 0.3 seconds off of a recent record time you may have heard about. Maybe, it's high time to hit the track again..." Color us intrigued.

To beat Porsche, Mercedes-AMG will need to lap the Nurburgring in less than seven minutes and 29.81 seconds at the longer course and seven minutes and less than seven minutes and 25.04 seconds around the shorter version. Previously, lap record attempts didn't include a 656-foot section of track that was used as a public entrance, but new regulations require lap record attempts to cover the full 12.9-mile Nordschleife track.

It remains to be seen if Mercedes-AMG is planning to take the GT 63 S back to the Nurburgring for a rematch. Since it only needs to beat the Panamera by 0.3 seconds, it's possible that Mercedes could reclaim the lap record with the AMG GT 63 S.

Alternatively, Mercedes-AMG could attempt a new lap record in the upcoming GT 73 hybrid executive sedan, which is rumored to pack an electrified 4.0-liter twin-turbo V8 producing 800 horsepower. That's nearly 200 more ponies than the new Panamera Turbo S, so it should have no trouble reclaiming Mercedes-AMG's lap record from Porsche. If this is the case, the reveal of the Mercedes-AMG GT 73 could be sooner than we thought.
