4.24v. - 1990 to 1992
As early as 1983, Maserati introduced a four-door branch in the Biturbo family tree, which followed a parallel evolution to the coupé and Spyder, without interfering with the more upmarket Quattroporte range. Thus in 1990, the 4.24v. mirrored the 2.24v. as a saloon alternative, exploiting the latest 4-valve per cylinder, 4 overhead camshafts evolution of the V6 engine.
Styling-wise, blacked-out chrome trim, specific bumpers and rocker panels along with a very discreet spoiler on the boot conferred a very sporty yet refined allure to this high-performance saloon.
The independent suspension featured active electronic control on all four wheels, whilst the interior's plush mix of leather and wood trim conveyed a feeling of exclusivity. 384 cars were sold between 1990 and 1992, before it was replaced with the second series.
