The Benetton B193 is a Formula One racing car with which the Benetton team competed in the 1993 Formula One World Championship. Designed by Ross Brawn and Rory Byrne, the car was powered by the latest Cosworth HBA engine in an initially-exclusive deal with Ford, and ran on Goodyear tyres. It was driven by German Michael Schumacher and veteran Italian Riccardo Patrese.
The car was distinguishable from its predecessor due to its track being 15 cm (5.9 in) narrower per the regulations of 1993, and the addition of bargeboards at the Monaco Grand Prix. It also had sidepods with a less pronounced cut-in for the radiator ducts. The nose height was raised from that of the B192, as well as having a longer and flatter rear 'deck' to allow for smoother airflow over the rear suspension than the B192.
In terms of performance, it was an improvement on the 1992 competitor.
The standard rear-wing endplate profile was also changed, featuring a straight leading edge rather than the curved design of the B192. Later in the season, this would further change with the addition of the 'forward wing'; an additional cantilevered wing used on high-downforce tracks, mounted forward and above the main plane, attached via endplate extensions. The leading edge of the front wing now also followed a straight profile, rather than curving forward towards the endplates. The leading edge of the nose also followed a smoother curved profile, whereas the B192 was flatter at its tip.
The car was very advanced in the technological sense and featured active suspension, semi-automatic transmission, and traction control, from the Monaco Grand Prix onwards, although Riccardo Patrese did later say that the car was a step down in quality compared to the much more sophisticated Williams cars he had been driving for the previous five years.
It was the last car to feature cigarette brand Camel as the team's main sponsor, before the long term sponsorship of an Enstone-based team with Mild Seven cigarettes.
Benetton eventually finished 3rd in the Constructors' Championship just behind McLaren but with a substantial gap to Williams. The B193B was replaced for the 1994 season by the Benetton B194.
