Info
In 1973, the Lamborghini R 503 and R 603 were introduced. The updated model numbering now indicated the power and number of cylinders. The same lineup also included crawler tractors (e.g., C 503) and narrow fruit-growing tractors (R 503 S). The engine was a 3-cylinder air-cooled 2.8-liter. The transmission was fully synchronized 12+3. The diameter of the dual clutch was 11″.
At the end of the 1970s, the frame color changed from blue to dark gray, similar to the larger Lamborghinis, and at the same time, the design was slightly updated.
The production years of the models are approximate.

The data has been collected primarily from brochures. In some cases, sources contain conflicting information. In such cases, we have attempted to select the most reliable information.
There is particularly significant variation in speed data, which varies depending on factors such as tire size. For tires, only the size most commonly used in Finland is listed.
Other changes during the model history have been addressed in the text section. For the front axle lock, the Finnish term "hammaslukko" (gear lock) is used for all 100% locks.
