The RLTF (
Targa Florio) was the race version of the RL. It weighed half as much as the standard production models, despite the engine having seven main bearings instead of four and double carburetors. It was used among the 1923 Alfa race team, which had drivers like
Ugo Sivocci,
Antonio Ascari,
Giulio Masetti and
Enzo Ferrari. Sivocci's car had a green cloverleaf symbol on a white background; when he won the 1923
Targa Florio, that symbol was to become the Alfa team's good luck token. Five different RLSS were entered in the first
Mille Miglia in 1927, but only two completed the race. A 1925 RLSS version with rare, original bodywork by Thornton Engineering Company in
Bradford, UK, is on permanent display in the Targa Florio exhibit at the
Simeone Foundation Automotive Museum in Philadelphia, PA, USA. It is one of only 9 RLSS still in existence.
