As early as 1983, Maserati introduced a four-door branch in the Maserati 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.
All Maserati models introduced from the Biturbo’s inception in 1981 until 1997 were based on the original Biturbo architecture. Among them the coupés as the 2.24v. and the Racing, saloons as the 420, 425 and 430, the convertible Spyder, the Karif, the 228, the later grand tourers like Shamal and Ghibli II, as well as the Maserati Barchetta which used an ultimate version of the biturbo V6 engine.
