Maserati Mistral Spyder 3.7
from 1964 to 1970
Maserati customers who wanted to purchase a Mistral Spyder could choose between no less than three different engines, of which the 3.7 liter version was the middle option. Already available in the coupé and in the Sebring, it became a somewhat less popular choice, when, in 1966 the new 4 liter unit was introduced. However, more than half of the total Mistral Spyders assembled were produced with the 3.7 liter engine. A customer could specify an automatic gearbox on both the 3.7 and 4.0 liter versions.
