The Williams FW16 is a Formula One car designed by Adrian Newey for the British Williams team. The FW16 competed in the 1994 Formula One season, with Williams winning the Constructor's Championship, and British driver Damon Hill finishing runner-up in the Drivers' Championship. It is notable as the last car to be driven by three-time world champion Ayrton Senna before his fatal accident during the 1994 San Marino Grand Prix. Its engine was a Renault RS6 3.5 V10. The team's main sponsor was Rothmans, replacing Camel Cigarettes and Canon used on the FW14 and FW15C. The car was designed around the major regulation changes that the FIA had introduced in the off-season, banning the various electronic devices that had been used by the front running cars during the preceding two seasons.
