The Alfa Romeo G1 was the first all-new design from Alfa Romeo after the end of the A.L.F.A. brand. Giuseppe Merosi, while engaged in a legal dispute with Nicola Romeo regarding the brand takeover conditions, designed the update for the prewar 24HP into the revised 20/30ES and the new luxury G1.[1] The chassis was lengethened and stiffened from the 1914 40-60 HP model, entering into market territory competition with Rolls-Royce. A new 6.3 L (384 cu in) straight-6 engine was introduced, producing 70 bhp (52 kW) and 216 lb⋅ft (293 N⋅m) of torque.[2] The G1 achieved a maximum speed of 86 miles per hour (138 km/h), winning its production class at the Coppa del Garda race.[2] Total production was only 52 copies; it found virtually no customers in Italy and all 50 (bar 2 prototypes) found their way to Australia. Only one known survivoir exists; is owned by New Zealand's Alfa importer and is the oldest surviving Alfa Romeo-branded car.[3][4]

The Alfa Romeo G2, a planned improved version, was never produced after the commercial failure of the G1.
