The Benetton B193 was a Formula One racing car designed by Ross Brawn and Rory Byrne and raced by Benetton team in the 1993 Formula One season. It was powered by the latest Cosworth HBA engine in an initially-exclusive deal with Ford and it ran on Goodyear tyres.

The car is 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 San Marino Grand Prix. It also had sidepods with a less pronounced cut-in for the radiator ducts. The nose height was also raised vs that of the B192, and the 1993 car has a longer flatter rear 'deck' to smooth airflow over the rear suspension than the early B192. The standard rear-wing endplate profile 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 rather flatter at its tip.

In terms of performance it was an improvement on the 1992 competitor.

Thanks to the more powerful engine, Michael Schumacher was able to consistently challenge the McLarens and on occasion challenged the seemingly unbeatable Williams FW15C.

It is arguable that it was overall the second most competitive car on the grid, behind the Williams, with Schumacher regularly scoring podiums and out-qualifying the single-lap ace Ayrton Senna in 8 of the 16 races of the season. Having access to the most potent factory engine in contrast to McLaren having to make do with older-specification units gave Benetton a power advantage, (although Williams used a far superior Renault V10), however the McLaren had the edge at some races, in particular in wet conditions due in part to their use of traction control. Due to McLaren's early-season results (achieved in part against the B193A run in South Africa and Brazil) McLaren were able successfully lobby Ford to provide engines of equal-spec to Benetton from Hockenheim onward, with both running the Series VIII of the HB V8, where previously Benetton's exclusive deal had seen McLaren using the Series VII which Benetton also ran in the B192/B193A.
