Ferrari 625 LM

In response to the 1955 Le Mans disaster, the ACO imposed new engine size limits and prototype entry restrictions for the 1956 24 Hours of Le Mans. This led Ferrari to modify three 500 TR barchettas with a larger 2.5 L engine, creating the 625 LM, as their 3.4 L 860 Monza and 3.5 L 290 MM could not compete under the new rules. The 625 LM's engine, a slight modification of the 625 F1, featured a reduced compression ratio of 9:1 and dual Weber 42DCO/A carburettors. Of the three 625 LMs, only the Gendebien/Trintignant car finished, securing third place behind a privately entered Jaguar D-Type and a factory Aston Martin DB3S. The bodywork of three of the four cars, designed by Carrozzeria Touring, resembled the 750 Monza, including the faired-in headrest.
