From the Cisitalia liquidation, Abarth obtained five 204 sports cars (two complete Spiders and three unfinished), a D46 single-seater, and various spares.

In addition to Guido Scagliarini, the "Squadra Abarth" racing team lined up celebrated drivers, including Tazio Nuvolari, Franco Cortese, and Piero Taruffi.

Notably, Tazio Nuvolari made his last appearance in racing at the wheel of an Abarth 204A, winning its class in the Palermo–Monte Pellegrino hillclimb on 10 April 1950.

[8] Alongside racing, the company's main activity was producing and selling accessories and performance parts for Fiat, Lancia, Cisitalia, and Simca cars, like inlet manifolds and silencers.

[11] Abarth accordingly went on to enter their cars in countless hillclimbing and sports-car racing events across the world, mainly in classes from 850 to 2000 cc, competing with Porsche 904 and Ferrari Dino in the higher echelons.

Since they were paid based on the number of results, Abarth entered their cars in every conceivable class and in countries across the entire world.

Abarth produced high-performance exhaust pipes, diversifying into tuning kits for road vehicles, mainly for Fiat.

Lambretta even held several 125 cc motorcycle land speed records during the 1950s due partly to the exhaust that Abarth developed for them.

This car had an unfortunate gestation period and never attained much success in competition, while Abarth himself favored the rear-engine layout and kept offering both types.

Colucci's next design, the Group 4 1000 SP, was much more successful and spawned a range of mid-engined, tubular-framed, fibreglass-bodied sports prototypes.

In 2017, Abarth collaborated with Yamaha to produce a limited-edition motorcycle, the "Sport Heritage café racer special".
