For 1953, Ferrari released a second series of its 166 Mille Miglia (MM) for sports racing in the popular sub-2.0-litre sport class. These used the 1995cc V12 engine with new Weber 32IF4C carburettors, producing a healthy 160hp at 7200rpm. The so-called 166 MM/53 was sold alongside the 250 Mille Miglia (3.0 litres) and 340 Mille Miglia (4.1 litres).
