The Maserati 4.18v was a combination of the 2.24v drivetrain and engine with the 422 body. It was part of the BiTurbo range.
Launched in December 1990, the 4.18v was a model very similar to the 422, destined to the Italian market with the traditional 3-valve-per-cylinder heads rather than the 4-valve-per-cylinder arrangement of the 4.24v. Its main feature was the ABS fitted as standard, a first for the Biturbo family.
Produced in only 77 units, this particular model is unquestionably one of the rarest amongst the Biturbo range.
