In 1911 FIAT produced seven examples of its S74 Corsa. One of these Grand Prix vehicles driven by David Bruce-Brown won the American Grand Prix at Savannah. Louis Wagner, on the other hand, finished second in the 1911 French Grand Prix.

The FIAT S74 Corsa has a steel chassis and is equipped with a 14.137 cc four cylinder engine composed of a pair of two cylinder units. This engine with 150 mm bore and 200 mm stroke is produceding 190 hp at 1600 rpm. This engine is fitted with overhead valves. The power of this front engine is transmitted to the rear wheels by chains through a multi disc clutch and a four speed forward and one reverse gearbox with side gear lever. The front and rear suspensions are by rigid axles and semi-elliptic springs.

The claimed top speed is 165 kph (102 mph). The unladen weight is announced at 1250 kg (2755 lb.) This car is considered a typical giant Grand Prix car of its time.

In 1911, FIAT also produced the FIAT S76 as a one-off record vehicle to challenge the speed record of the Blitzen Benz ( 212 kph or 131,7 mph).

The Fiat S76 car had one of the largest capacity engine in an automobile. The 28.353 cc four cylinder engine is made up of two blocks of two cylinders and produces 290 hp at 1900 rpm. The engine bore is 190 mm and the stroke is 250 mm. In fact the volume of one cylinder is so huge that three spark plugs are installed in each one in order to get even combustion. The transmission is by chain with a multi disc clutch and a four-speed gearbox commanded by a side gear lever. The suspensions are at front and rear with rigid axle and semi-elliptic springs.

 The FIAT S76 was first tried at Brooklands in Great Britain and later at Saltburn Sands where Pietro Bordino reached 200 kph (124 mph). In 1912 a French driver, Arthur Duray, reached 225 kph (137 mph) on the Ostend straight but the record was not homologated because of lack of efficiency of the timing equipment.

This FIAT S76, nicknamed the Beast of Turin, is fitted with an aerodynamic body for the time including an undershield from the front axle backwards. The pear shaped radiator was introduced to link the cooling surface with the car shape. The unladen weight is announced for 1650 kg (3647 lb). The length of the car is 3750 mm (12 ft 3 5/8 in.).
