Williams FW15D test Estoril 1994

he 1994 car wouldn't be ready for several weeks, so Williams adapted the 1993 FW15 for the 1994 regulations. Electronic driving aids such as active suspension, ABS, and traction control were banned for '94. The new rules meant that traditional passive suspension returned, and the drivers had to control wheelspin manually. The team proudly displayed Senna, Hill, and the FW15D «interim» car to the World's media.
