over the start line than the atmospheric Benettons (who were also the fastest of the atmos at Tosa with ) and were also slower at the start/finish line than the Zakspeeds, showing just how much trouble they were in. One of the surprises of qualifying was American veteran Eddie Cheever. Not noted as the best qualifier, Cheever qualified 8th in his Arrows-Megatron, though he was still 4.1 seconds behind Senna. Cheever and Arrows had tested at Imola a week before the race and came up with a set-up they liked. The same settings were put on Derek Warwick's Arrows but the Briton admitted he found the settings lazy and could only qualify 14th, 1.2 seconds slower than his teammate. The turbocharged Arrows', with Cheever and Warwick still hampered by the pop-off valve cutting in early, were touching just under on the run to Tosa to make them the fastest behind the Honda powered cars. The EuroBrun-Ford Cosworth of Oscar Larrauri, the Ligier-Judds of Stefan Johansson and former Imola pole winner René Arnoux, and the Zakspeed turbo of Bernd Schneider all failed to qualify, while the Osella of Italian Nicola Larini was excluded after scrutineering when it was discovered that the car's engine mounting points had been illegally changed. The scrutineers ruled that this constituted an entirely new chassis for the Osella FA1L and as the new chassis had not yet been crash approved by FISA, the team was excluded from the meeting. For Ligier it was the first time since the team's début in Formula One in that neither car had qualified for a race. For Arnoux it was a bitter pill to swallow as he had sat on the pole at the circuit three times previously when he had driven for both Renault (1980 and 1982) and Ferrari (1983). Johansson, driving for Ferrari (1985 and 1986) and McLaren the previous year, had finished each race in the points. After qualifying, Lotus team boss Peter Warr and lead driver Nelson Piquet made the claim that despite the three second gap between the McLarens and the rest of the field, they believed the Lotus and even the Ferraris were better aerodynamically than the McLarens and that would hurt their fuel consumption on what was one of the most fuel thirsty circuits on the calendar. Warr predicted the McLarens would not be able to maintain their advantage and still finish the race
