Toyota ended up fastest after the first two free practice sessions ahead of Saturday's Sao Paulo 6 Hours, this weekend's round of the FIA World Endurance Championship.
Nicolas Lapierre topped the times aboard the solo Toyota TS030 Hybrid in the second of the two practice sessions on the opening day at Interlagos. He set a time of 1m23.272s in the dying seconds of the Thursday afternoon session to eclipse teammate Alex Wurz's previous benchmark of 1m23.623s.
The best Audi time around the 2.68-mile Brazilian track was a further tenths slower. Sports car debutant Lucas di Grassi set a 1m23.710s in the non-hybrid Audi R18 ultra he is sharing this weekend with Allan McNish and Tom Kristensen.
Di Grassi was a further three tenths clear of the Audi R18 e-tron quattro in the hands of Benoit Treluyer. The hybrid Audi, which leads the WEC drivers' points with Treluyer, Andre Lotterer and Marcel Fassler, had been fastest in Lotterer's hands in the opening 90-minute session.
The LMP2 class was led by Olivier Lombard and Roman Rusinov in the two Signatech ORECA-Nissan 03s. They were separated by just three one thousandths of a second after the new-tire runs in the second session.
The GTE times were topped by Darren Turner in the solo factory Aston Martin Vantage GTE. The Briton set a time of 1m34.001s late in the second session to leapfrog Marc Lieb in the best of the Felbermayr-Proton Porsche 911 GT3-RSRs by four tenths.
