Alfa Romeo 158

Alfa entered 1950 with a car designed twelve years earlier and won every race it started. By 1951 it was drinking fuel at about 1.5 miles per gallon and needed two stops where the Ferrari 375 needed one; Fangio won the title anyway, at Barcelona, when Ferrari picked the wrong tyre size. Alfa then withdrew from Grand Prix racing entirely rather than build a successor, which is why 1952 and 1953 were run to Formula Two rules.

One of the design family that has a specified page of its own.

Why it mattered

The idea. A pre-war voiturette design, hidden through the war and brought back to win the first two World Championships

New on this car. Nothing new: the point of the 158 is that a 1938 design was still the best car in the world in 1951

What it did. Every race entered in 1950; 4 of 7 in 1951. Drivers' titles for Farina and Fangio.

A blank is a figure nobody published for this car. Where several teams quote the same number in a season it is usually the rule they were all built to rather than a measurement, so it is kept with the regulation limits instead of here.

6 wins can be traced to this chassis; its article publishes 37. Neither is wrong. A win counts here only where the entry list says which car the driver was in, and a team running two designs in a season does not always say. The unresolved seasons are listed below.
