Alfa Romeo Twin Spark (TS) technology was used for the first time in the Alfa Romeo Grand Prix car in 1914. In the early 1960s it was used in their race cars (GTA, TZ) to enable it to achieve a higher power output from its engines. And in the early and middle 1980s, Alfa Romeo incorporated this technology into their road cars to enhance their performance and to comply with stricter emission controls.

The Alfa Romeo GTA is a coupé automobile manufactured by the Italian manufacturer Alfa Romeo from 1965 to 1971. It was made for racing (Corsa) and road use (Stradale).
