Taking over the #51 Ferrari 499P for the second part of the three-hour session, Shwartzman set an impressive time of 1m48.559s in his first day of running in an LMH car.
The 24-year-old’s lap was fractionally faster than the time with which Will Stevens set the pace this morning in the Jota Porsche, which meant he also topped the overall order at the end of the day.
The Ferrari Formula 1 reserve driver shared the car with fellow Ferrari factory driver Lilou Wadoux, who managed to improve her time by nearly seven seconds in the afternoon after a short run in the morning session.
Wadoux, who also ran in the Toyota GR010 Hybrid at the same test last year, posted a best time of 1m49.488s, which was nine tenths slower than what Shwartzman managed later in the session.
Second place in the afternoon went to Jota, with Norman Nato setting a time of 1m49.130s after driving the team’s customer Porsche 963 on his own in the session.
Robert Kubica was due to appear in the car ahead of an expected Hypercar programme with Jota in 2024, but the Polish driver didn’t turn up for the test that took place a day after his LMP2 title success with WRT.
In the absence of Kubica, Nato only completed 13 laps of the track in the car that finished a season-best fourth in the Bahrain 8 Hours.
