Model history: Although Ferrari dominated the Formula 2 class in 1949 with their 2-litre V12 engine, Enzo Ferrari had his eye on HWM's four cylinder Alta engine. One of the biggest advantages of the 'four' was its superior fuel effency compared to the gas-guzzling V12. Ferrari's new chief engineer Aurelio Lampredi set out to design a four cylinder to replace the Gioacchino Colombo designed V12. When the sports governing body decided that the World Championship would be run under Formula 2 regulations, the development of the 'four' got top priority.
Lampredi jointly developed a 2 and 2.5 litre engine, both sharing many interchangeable parts. Completely constructed of light alloy, the engine featured a double camshaft head. The 2-litre engine made its debut in 1952 in the 500 F2. Alberto Ascari drove it to the World Championship, winning six of the seven championship races. He took another championship a year later. In good Ferrari tradition, the Grand Prix engine was also fitted in a sportscar chassis. After two experimental models built in 1953, the 2.5 litre 625 TF and 3 litre 735 S, two four cylinder 'production' sports cars were released in 1954.
First up was the 3 litre model, which debuted at the Gran Premio Supercortemaggiore at Monza and was aptly called 750 Monza. The Gonzales/Trintignant driven 750 Monza featured a Dino Ferrari designed body and took a debut victory. Late in 1953 a 2-litre prototype was first raced. Fitted in a 250 MM chassis, Alberto Ascari and Luigi Villoresi drove the four cylinder to a class victory. To commemorate Ferrari's back-to-back World Championships, the 2-litre production car was dubbed 500 Mondial.
Both cars were campaigned by the works team and customers. The successes of the four-cylinder single seaters could not be matched, but various class victories were scored. Career highlights for the 500 Mondial was a second place in 1954 Mille Miglia and a class victory in the 1956 12-Hours of Sebring race. After the successful Monza debut, the 750 and subsequent 860 Monza struggled to match the highly competitive rival. A 1-2 victory in the Sebring 12-Hours of 1956 was the Monza's career best.
To keep up with the dominating Maseratis, Ferrari's new chief engineer Vittorio Jano set out to design a new 2-litre racer, but still using the Lampredi four cylinder engine. Dubbed 500 TR, it made a victorious debut at the 1956 Supercortemaggiore. Not much later it was joined by the similar, but larger engined 625 TR. These were the last four cylinder racers produced by Ferrari and for the next generation of small sports cars Ferrari used six and eight cylinder engines.
With their 3.5 litre engines the three 860 Monzas were not only the largest four cylinder engined Ferraris, they were also the most successful. Prepared for the 1956 season, they scored a fabulous 1-2 finish at their racing debut in the Sebring 12 Hours of that season. The winning car was sold to prominent American racer John von Neumann and driven to several podium finishes and wins by him, Phil Hill and Richie Ginther. Together with a third chassis the other continued to and was instrumental in winning the 1956 World Championship alongside the very similar but V12 engined 290 MM.
Chassis: 0604M
Chassis 0604M was driven to a debut victory in the 1956 Sebring 12 Hours by Juan Manuel Fangio and Eugenio Castellotti. It was successfully raced until 1959 and has since been owned by some of the most prominent Ferrari collectors like Pierre Bardinon and Jean Sage. This most important Ferrari racing car was offered for a staggering $3.5 million late in 2006 and has since been sold to Italy. It is seen here at the 2007 Concorso d'Eleganza Villa d'Este; one of the first outings for the new Italian owner. A month later he entered the beautiful Scaglietti bodied machine in the Mille Miglia retrospective.
Thanks so much for sharing your fascinating stories on your website bella205 and especially your experiences with your fabulous FERRARI 860 MONZA. I did read about your LOTUS 15 and your B FORD 1932 ROADSTER too.
Fascinating stuff.
You are obvously a talented and creative man who loves his cars and the way you solved many mechanical and restoration problems is also a real testament to your ingenuity and perserverance.
BTW bella205, in view of my post, how smooth to drive was the engine of your MONZA?
Archetypical FERRARI is SUPERB!

WOW! What a fabulously elegant and beautiful car. Hardly a wrong line or detail except for the ugly exposed fuel filler cap which only looks out of place as the rest of the car flows so seamlessly.
Another FERRARI which oozes "purpose with beauty" - the philosophy they have always passionately expressed and which has continued to delight not only FERRARI “Tifosi” but car lovers all over the globe. AVANTI FERRARI!
BTW, at 3.4 litres what a lump of an engine! The inherent vibration of this large inline four cylinder four stroke must have been a problem and I wonder how the FERRARI engineers solved it.
Rather than using a bigger flywheel with all the attendant extra weight problems perhaps FERRARI used a development of the English genius Professor Frederick Lanchester's 1904 invention of two eccentrically weighted counter rotating balance shafts driven either side of the crankshaft at twice engine speed to smooth things out?
MITSUBISHI refined the principle in the 1970's with balance shafts located diagonally and driven by chains from the oil pump. Their diagonal location also eliminated sideways vibrations at high RPM's and their "Silent Shaft" patents were subsequently licensed to Fiat, Saab and Porsche. Many world Marques now use balance shafts in their engines.
