Qualifying for the 1985 Brazilian Grand Prix was held in two sessions with the first on the Friday and the second one on the Saturday. In the Friday session,
Lotus who did some aerodynamic tweaks to
their Renault powered car, similar to the
Lola's new
CART Indycar, went to the top of the timesheets on Friday morning. But
Elio de Angelis wouldn't be able to improve on his time with the driver responding after the second qualifying session, "I am sure I could have retained the pole." Senna would improve on his lap time but only slightly as he finished behind de Angelis on the grid in fourth. On the front row of the grid,
Michele Alboreto would claim the first pole position of the season with a time of 1:27.768, a full one second ahead of his time on the Friday and 6/10ths faster than the
1984 pole time set by Elio de Angelis. Alboreto's teammate in
Rene Arnoux also improve his time by a second, but the Frenchman had to start the race in seventh place, using the spare car after the
Ferrari engine was down on power on his
main car. Also on the front row of the grid was
Keke Rosberg in the
Williams-
Honda who earlier in the weekend had a blown turbo from their engine on the Saturday morning. But one flying lap secured Rosberg a front row start with teammate
Nigel Mansell starting from fifth.
McLaren also has engine issues with the
TAG-
Porsche turbos. The TAG engines were known not to be able to take higher qualifying boost like the
BMW, Renault and Honda engines. But in qualifying, try as they may, McLaren just couldn't get the TAG's to run properly at high boost with both
Alain Prost and reigning World Champion
Niki Lauda struggling to 6th and 9th places respectively. Eighth on the grid was the first of the Pirelli's with
Brabham-BMW driver,
Nelson Piquet being the quickest. Brabham's long-time Chief Designer and Technical Director
Gordon Murray advised that their winter testing had been for the best race tyre and not for taking any pole positions in the first few races of the season (Piquet had taken 9 poles in , but had only finished 7 races). Rounding out the top ten was
Renault driver,
Derek Warwick who was 2.3 seconds off the pace. His team-mate,
Patrick Tambay who started behind him in 11th advised that
Renault RE60 was "four seconds behind the pace when we first tested the car here a month ago. Now it had been reduced to two seconds."
