This superb single-seater had already won in the streets of the Principality in 2016, at the hands of the same Stuart Hall. It has not aged a bit and was only overtaken at the first corner by Jordan Grogor‘s Matra MS120C. But the South African based in Dubai was then penalized ten seconds for having anticipated the start, which did not prevent him from reaching the podium at the end. The main beneficiary of this penalty was Michael Lyons, 4th on the grid, who finished 2nd in his Surtees TS9. The young Briton also profited from the retirement of the BRM P153 (ex-Pedro Rodriguez) of Mexican Esteban Gutierrez, which brutally stalled at the tunnel exit chicane, for a purely mechanical reason.
