Description

The Ferrari 512 M, introduced in late 1970, was the ultimate evolution of the 512 S and represented Ferrari’s final push to counter the dominance of the Porsche 917 in the Group 5 sports car wars. The “M” stood for Modificata, reflecting the extensive modifications made to improve the performance, reliability, and aerodynamics of the original 512 S, which had shown promise but struggled against Porsche’s superior pace and endurance at events like the 24 Hours of Le Mans.

The 512 M retained the same basic 5.0-liter V12 engine but with significant refinements. Power output was increased to around 610 horsepower at 9,000 rpm thanks to higher compression, revised cylinder heads, and improved fuel injection. The engine was paired with a new Ferrari-designed five-speed gearbox, which was lighter and more reliable than earlier versions. The chassis was strengthened, while the suspension was revised for better handling balance and tire management over long stints. The car’s weight was reduced through the use of more fiberglass components, enhancing both agility and acceleration.

One of the most noticeable changes was the aerodynamics. The 512 M featured a new, sleeker body designed in Ferrari’s wind tunnel, replacing the bluff, aggressive nose of the 512 S with a smoother front section. The rear deck was reshaped for improved airflow and downforce, while large air intakes were added to cool the powerful V12. The result was a car that looked significantly more modern and purposeful, its flowing curves and lower stance giving it a striking presence on the track.

In competition, the 512 M proved much more effective than the 512 S. It debuted late in the 1970 season and immediately showed its potential, but its finest hour came in 1971. At races such as the 24 Hours of Daytona and the 1000 km of Monza, the 512 M demonstrated pace and reliability that put it on more equal footing with the Porsche 917. However, Ferrari had already shifted its factory focus toward the upcoming 312 PB for the new 3.0-liter prototype regulations, leaving the 512 M largely in the hands of privateer teams. Despite this, it scored strong results and remained competitive against the 917s throughout 1971, contributing to some of the most legendary duels in endurance racing history.

Only a small number of 512 S cars were converted into M specification, with fewer than 20 examples in total. This rarity, combined with its historical importance, has made the 512 M one of the most desirable Ferrari prototypes of the era. Its balance of power, beauty, and competitiveness embodies Ferrari’s relentless spirit in one of the greatest rivalries in motorsport.

Today, the Ferrari 512 M is revered as the high point of Ferrari’s 5.0-liter endurance racers. It represents both the end of the line for the big-displacement V12 prototypes and the closing chapter of Ferrari’s legendary duels with Porsche before regulation changes transformed the sport. With its breathtaking performance, sculpted design, and connection to one of racing’s most iconic eras, the 512 M stands as one of the most evocative and collectible Ferraris ever built.
