The V4 (V stood for the cylinder formation and its 4 litre capacity) engine was projected by Alfieri Maserati and designed by Piero Visentini. This engine powered the 1929 Tipo V4 Maserati. Known as the "Sedici Cilindri" this 16-cylinder was built around two Tipo 26B engines mounted on a common crankcase, with two crankshafts and gearing into a common box. The various component parts consist of 55 ball races, 27 gears plus 8 gears in the oil pumps, 2 crankshafts, 16 con-rods and pistons, 32 valves, 64 valve springs, four camshafts, two superchargers, four oil pumps and two water pumps. Both crankshafts run clockwise, driving a central gear which runs anti clockwise. This means the crown wheel and pinion are fitted the opposite way round.
In July 1929 a V4, driven by Borzacchini, attained 152.9 mph over 10 kilometres on the 25 mile circuit at Cremona in Italy.The fastest speed for a racing car was recorded . During the 1929 Italian Grand Prix, Alfieri Maserati drove the V4 to a lap speed of 124.2 mph, a record not beaten until 1954. The V4 was succeeded in 1932 by the V5, this 5-litre engine produced 330-360 bhp @ 5200 rpm.


Years of production: 1932-1937
Straight 4-cyl 1088.4 cc engine
DOHC with two valves per cylinder
Bore 65mm and stroke 82mm
Compression ratio 5.0:1/6.0:1
Power output 140bhp @ 6800 rpm
Induction system by Roots supercharger
No 1 Weber 55ASI carburettor.

On the 28th November 1934, this 4CM (4 Cylinder Monoposto) engine was mounted in the streamlined version of the Tipo 4CM, owned and driven by engineer Giuseppe Furmanik, that broke the world record for the flying kilometre for the 1100 cc class at an average speed of 222.634 kph. The previous record of 207.527 kph was held by an MG.


Years of production: 1936-1939
Straight 6-cyl 1493.2 cc engine
DOHC with two valves per cylinder
Bore 65mm and stroke 75mm
Compression ratio 6.0:1
Power output 155/175bhp at 6200/6600 rpm
Induction system by Roots supercharger
No 1 Weber 55ASI (55CDO/45DCO).

This engine is a Maserati masterpiece with the cylinder head cast in block with the heads, paired by twos on a common crankcase in elektron as are the undercasing and the oil sump.
This engine was fitted to the streamlined 6CM single-seater, capable of a speed of 230 km/h, which dominated European races in the "Voiturette" class for cars up to 1500 cc between 1936 and 1939.


Years of production: 1940-1946
Straight 8-cyl 2981.7 cc engine
DOHC with four valves per cylinder
Bore 78mm and stroke 78mm
Compression ratio 6.5:1
Power output 415/430bhp @ 6400/6800 rpm
Induction system by twin Roots superchargers
No 2 Memini carburettors.

Derived from the 4CL, the 8CL (8 Cylinder Lineale - 'in a straight line') was composed of two cylinder blocks mounted in line on a common crankcase. Designed between 1939 and 1940, it was the logical evolution of the 8CTF (8 Cylinder Testa Fissa - 'Fixed Head') engine which in those same years (1939 and 1940) powered the 8CTF, driven by Wilbur Shaw, to victory in the 'Indianapolis 500'. This modern supercharged engine, with its four valves per cylinder and equal bore and stroke measurements, was prematurely ended by the outbreak of World War II. After the war, the Grand Prix formula was changed and the 8CL engine, no longer valid for the European races, was raced at Indianapolis by Luigi Villoresi in 1946 and by the American Fred Agahashian in 1949.


Years of production: 1946-1950
Straight 6-cyl 1488.2 cc engine
SOHC with two valves per cylinder
Bore 66mm and stroke 72,5mm
Compression ratio 7.25:1
Power output 65bhp @ 4700 rpm
Induction system by a single Weber 36 DCR carburettor.

The A6 (Alfieri 6 cylinder) was the first Maserati engine built primarily for a modern Gran Turismo car and not for racing. First designed in 1941 but not developed until after World War II, this straight-6 single overhead camshaft engine was fitted to the A6 car designed by Pinin Farina. The car had a top speed of 150 km/h and was quite successful commercially with 61 examples (2 in 1946, 3 in 1947, 9 in 1948, 25 in 1949 and 22 in 1949) being built.


Year of production: 1952-1953
Straight 4-cyl 1994.9 cc engine
DOHC with four valves per cylinder
Bore 88mm and stroke 82mm
Compression ratio 12.0:1/13.5:1
Power output 182/195bhp @ 7000/7500 rpm
Induction system by two Weber DBO carburettors
Later by direct fuel injection.

The Tipo 4CF2 (4 Cylinder Formula 2) was the prototype of an engine designed as an alternative to the 6-cylinder A6GCM engine for the 2-litre Formula. It was an extremely modern design having a crankshaft which could be dismantled but was abandoned in favour of a 6-cylinder engine. In 1953 Maserati engineer Giulio Alfieri tested a direct fuel injection system, supplied by Bosch, with disappointing results. The Tipo 4CF2 represented the last efforts of Alberto Massimino before his departure from the factory.

I liked these two paragraphs from Denis Jenkinson's excellent book 'THE MASERATI 250F - A Classic Grand Prix Car'.
'All-night sessions were normal for the engine department, and test-bed running took place at all times of the day and night. For the enthusiast in Modena during 1957 it was an exciting time, for he would often be woken from his slumbers at four o'clock in the morning by the sound of a V12 engine on the test-bed running at nearly 10,000 rpm and screaming its heart out through open megaphone exhausts, or by the fantastic bellow of the 4.5-litre V8 engine developing 400 bhp at 7000 rpm, both of which could be heard a long way from the Viale Ciro Menotti.
......In bars and restaurants in the town there were often heated arguments between those who enjoyed being woken up by the sound of a racing engine and those who objected.'



Years of production: 1954-1958
Straight 6-cyl 2493.8 cc engine
DOHC with two valves per cylinder
Bore 84mm and stroke 75mm
Compression ratio 12.0:1
Power output 240/270bhp @ 7200/8000 rpm
Induction system by three Weber 42 DCO3-45 DC03 carburettors (in 1953 also direct fuel injection).

This engine powered the 250F single-seater with which Juan Manuel Fangio won the 1957 F1 World Championship. The 250F single-seater had a very long and successful race career taking part in all F1 World Championship races from 1954 to 1960, when a change in the regulations for Formula 1 restricted the engine size to 1.5-litres.


Years of production: 1957-1964
Straight 6-cyl 3485.3 cc engine
DOHC with two valves per cylinder
Bore 86mm and stroke 100mm
Compression ratio 8.5:1
Power output 220bhp @ 5500 rpm
Induction system by three Weber 42 DCOE carburettors.

Following the success of the Tipo 350S in sports car racing, Maserati took advantage of all their competition experiences by using this engine as the basis for all Maserati GT car production from 1957 to the early sixties.
The engine was mounted in the '3500GT Touring', 'Sebring', 'Vignale Spider 3500' and the 'Mistrals'.


Years of production: 1961-1964
Straight 6-cyl 3485.3 cc engine
DOHC with two valves per cylinder
Bore 86mm and stroke 100mm
Compression ratio 8.5:1
Power output 235bhp @ 5800 rpm
Induction system by Lucas fuel injection.


Years of production: 1959-1960
Straight 4-cyl 1990.2 cc engine
DOHC with two valves per cylinder
Bore 93.8mm and stroke 72mm
Compression ratio 9.8:1
Power output 200bhp @ 7800 rpm
Induction system by No 2 Weber 45 DC03 carburettors.

This engine, mounted in the Tipo 60' Birdcage', was evolved from that of the 200SI. Modifications to the twin-camshaft cylinder head, cast in Electron, were significant with the intake ports and the exhaust ports being reversed. The Tipo 60's low centre of gravity and beautiful aerodynamic shape was made possible by mounting the engine in the chassis at an angle of 45°. For this unusual arrangement it was designed with a triangular sump allowing the sump to be parallel to the road.

It was updated as:

1959-61 Tipo 612890.3 cc - 250bhp @ 6800 rpm
