The rest of the grid was powered by the Ford GBA V6 turbo in Benetton, with the only naturally-aspirated engine, the DFV-derived Ford-Cosworth DFZ 3.5 L V8 outputting in Tyrrell, Lola, AGS, March and Coloni. The massively-powerful BMW M12/13 inline-four found in the Brabham BT55 tilted almost horizontally, and in upright position under the Megatron brand in Arrows and Ligier, producing at 3.8 bar in race in race trim, and an incredible at 5.5 bar of boost in qualifying-spec. Zakspeed was building its own turbo inline-four, Alfa Romeo was to power the Ligiers with an inline-four but the deal fell through after initial testing had been carried out. Alfa was still represented by its old 890T V8 used by Osella, and Minardi was powered by a Motori Moderni V6.
