Brendon Hartley set the benchmark time of 1m47.272s early in the one-hour session aboard the #8 Toyota GR010 HYBRID, before Kamui Kobayashi lapped three tenths quicker soon after to record 1m46.954s in the sister #7 car.
That lap time proved to be the fastest of the entire week so far, ahead of Friday’s Sebring 1000 Miles.
Antonio Fuoco’s #50 Ferrari was best of the rest in third, setting 1m48.121s in the closing stages to pip Richard Westbrook in the sole Chip Ganassi Racing Cadillac V-Series.R LMDh, whose 1m48.265s was over a second off the pace of the Toyota duo.
The session was red flagged after 10 minutes, following a clash between Westbrook and Ryan Hardwick’s GTE Am Proton Porsche at Turn 7, which sent the 911 into the tyrewall. That removed 12 minutes from the available running time while the incident was cleared up and was under investigation by the stewards.
James Calado was fifth quickest in the sister Ferrari 499P, which is making its debut in Sebring, ahead of Olivier Pla’s Glickenhaus 007, which was 2.7s off the pace.
The best Porsche Penske Motorsport 963 LMDh was Fred Makowiecki’s #5 car, but it was almost 3s off the pace. The fastest Peugeot 9X8, meanwhile, was slower than the quickest LMP2 car in ninth overall.
A second, much shorter, red flag was required for Takashi Kimura's Ferrari spinning to a halt at Turn 3.
In LMP2, Pietro Fittipaldi led the way by setting 1m50.806s in the opening minutes in his #28 Jota ORECA-Gibson 07, and then extended his advantage with 1m50.326s.
That was almost four tenths clear of the closely matched United Autosports cars, which were just 0.007s apart.
GTE Am proved to be highly competitive with Alessio Picariello (Iron Lynx Porsche 911) leading in the early stages on 1m59.160s, beaten first by Casper Stevenson (D’Station Aston Martin) and then Nicky Catsburg (Corvette) and, eventually, Daniel Serra (Kessel Racing Ferrari 488) who set 1m58.845s.
Third free practice begins at 11:55 local time at Sebring on Thursday.
