 Thus the FG01 did not promise much in terms of performance . It was angular and bulky , with poor aerodynamic performance negatively affecting grip and handling ; it had a plump nose , initially no airbox , and was overweight and under @-@ powered , using a small Ford @-@ Cosworth ED V8 customer engine largely financed by Ford do Brasil , which developed an estimated 100 bhp less than the most powerful engine in the field , the Renault V10 supplied to the Benetton and Williams teams . It was also the only car to have a manual gearbox in the 1995 F1 season . The car was liveried in a distinctive yellow @-@ and @-@ blue colour scheme accompanied by fluorescent green wheel @-@ rims , illustrating the team 's Brazilian influence in its first year . The precise hue of each colour was chosen as a tribute to Ayrton Senna , who had been killed at the 1994 San Marino Grand Prix ; the cars were liveried in identical shades to those used on the Brazilian 's helmet design .
