Formula One: Mercedes add fuel to fire in Red Bull feud ahead of Qatar Grand Prix

As Lewis Hamilton and Max Verstappen fight it out — quite literally at times — on the track for the Formula One Drivers’ Championship title, the feud in the pit lane and stewards office between Mercedes and Red Bull is just as feisty.

Late on Tuesday, Mercedes called for a stewards’ review of the Sao Paulo Grand Prix incident between Hamilton and Verstappen after new evidence emerged that was unavailable at the time.

Red Bull’s championship leader Verstappen appeared to force Mercedes’ seven times world champion Hamilton off the track as they jostled for the lead at Interlagos last Sunday.

The stewards took note of the lap 48 incident during the race but concluded, on the basis of the evidence they had, that no investigation was necessary.

Hamilton eventually passed Verstappen 11 laps later and took the win.

“(Mercedes) confirms that we have today requested a Right of Review under Article 14.1.1 of the International Sporting Code, in relation to the Turn 4 incident between Car 44 and Car 33 on lap 48 of the Brazilian Grand Prix, on the basis of new evidence unavailable to the Stewards at the time of their decision,” the team said in a statement.

The article allows stewards to re-examine their decision if “a significant and relevant new element is discovered which was unavailable to the parties seeking the review at the time of the decision concerned”.

Race director Michael Masi revealed after the Grand Prix that stewards had not had access to now-released forward-facing cockpit video footage from Verstappen’s car.“ Only the cameras that were broadcast ... is what we have access to,” he said. “The forward-facing, the 360, all of the camera angles that we don’t get live, that will be downloaded and we’ll have a look at them post-race.”

Mercedes were particularly interested in the forward-facing video to see what steering movements Verstappen had made, with team boss Toto Wolff saying the Dutch driver should have received at least a five-second penalty.

In a dramatic weekend, Hamilton was disqualified from Friday’s qualifying and given a five-place grid penalty for using a new internal combustion engine at Interlagos.

Verstappen, on the other hand, was fined 50,000 euros ($56,710) on Saturday for putting his hands on the rear wing element of Hamilton’s car to inspect it after qualifying, a breach of the sporting code.

Hamilton is 14 points behind Verstappen with three races remaining and the next in Qatar this weekend.
