Based on these, the Tipo 26M was designed in 1930 as mostly single-seaters (M meaning monoposto) and also referred to as 8C 2500 (8 cylinder, 2500 cc).

Thanks to a 69 mm (2.72 in) bore, this engine's displacement is 2811.9 cc; maximum power is 205 hp (151 kW).

The 8C 2800 won at the IV Gran Premio di Monza (Luigi Fagioli, 6 September 1931) and I Mountains Championship at Brooklands (Tim Birkin, 17 October 1931).

Other drivers of 26M this year were Clemente Biondetti, Luigi Parenti, George Eyston, Pietro Ghersi, Umberto Klinger and René Dreyfus.
