G1 designed specially as an Alfa Romeo 1921

G1 two-seat sports roadster is the oldest Alfa Romeo in existence, the very first vehicle designed specially as an Alfa Romeo. There were only 52 of these magnificent creations built, powered by a 6.3-liter side-valve six-cylinder engine. The G1 was designed by Giuseppe Merosi. With its large six-cylinder engine it was the largest engine ever fitted to an Alfa Romeo to date.

With increasing gas prices and roughly six miles to a gallon, the car was not popular with many, thus the reason for only 52 being created. It was fitted with a four-speed manual gearbox and semi-elliptical front springs and dual quarter-elliptic at the rear. The brake was mechanical on the rear wheels. The engine was featured two cast-iron blocks each comprised of three cylinders. It was capable of producing 70 horsepower and an astonishing 216 foot-pounds of torque.
