The car was quite similar to the previous 20/30 HP Delta model.

[1] Three wheelbase lengths were offered, resulting in a choice of five different models—depending on the desired body style: The Epsilon was powered by a Tipo 58 side valve monobloc inline-four, displacing 4,080 cc, which produced 60 hp at 1,500 rpm.

[1] The separate body was built on a ladder frame; front and rear there were solid axles on semi-elliptic springs at the front and three-quarter elliptic springs at the rear.

The brakes were on the transmission and on the rear wheels.

The transmission was a 4-speed gearbox with a multi-plate wet clutch.
