The Ferrari 126C4 is the final evolution of the 126 design line. The car was good for a single win in the hands of Michele Alboreto. He won the Belgian GP at Zolder from pole position, notably the event where Ferrari driver Gilles Villeneuve was killed two years earlier, in 1982. Villeneuve back then was driving with number 27, the same as Alboreto's Ferrari in 1984. With just a single win, 4 second places and three thirds in the shadow of the dominant McLaren MP4-2, Ferrari finished runners-up in the championship after winning the constructors' championship twice, in 1980 and 1981.

Ferrari’s 126 C4 chassis was little changed, but its engine was revised considerably. Among the changes were completely redesigned cylinder heads, a deepened crankcase and many other internal modifications. The transverse-mounted gearbox was heavily improved as well, with the resulting six-speed unit stronger and lighter than before.

For the 1984 season, six 126 C4 chassis were completed, ranging from numbers 126-071 to 126-076.
