About the Alfa Romeo 40/60 HP
The Alfa Romeo 40/60 HP was a high-performance grand tourer and racing car designed by Giuseppe Merosi to compete in prestigious events like the Targa Florio. It featured a massive 6.1-litre overhead valve engine, a highly advanced configuration for the era that allowed it to achieve significant speeds. The model is most famous for serving as the basis for the 'Siluro Ricotti' Aerodinamica, one of the world's first teardrop-shaped streamlined cars. Its success on the track helped establish the sporting reputation that would define the Alfa Romeo brand for the next century.
