Editing Giuseppe Merosi (section)

== The RL and RM series ==

In 1921, Merosi introduced the [[Alfa_Romeo_RL_%26_RM|Alfa Romeo RL]], the marque’s first post-war six-cylinder production model.

The RL featured:

* Inline six-cylinder engine
* Overhead valves
* Four-speed gearbox
* Ladder frame chassis

The RL series became Alfa Romeo’s first commercially successful sports model and formed the basis for the factory’s early 1920s racing efforts.

From the RL evolved the competition-focused '''RL Targa Florio (RLTF)''' variants, which achieved a landmark victory at the 1923 Targa Florio driven by Ugo Sivocci. This success marked Alfa Romeo’s first major international triumph and established the famous quadrifoglio symbol as the marque’s racing emblem.

Merosi also designed the [[Alfa Romeo RM]], a four-cylinder derivative introduced in 1923, which offered a smaller-displacement alternative while maintaining sporting credentials.
