2.24v. - 1988 to 1992

2.24v.

The 2.24v was the logical development of the V6 engine incorporating twin overhead camshafts and 4-valve heads. A long toothed belt drove the exhaust cams, with short secondary chains driving the inlet cams. The engine, known internally as the V6-4AC-24, was launched at the Turin Motor Show in April 1988, while the car followed in December at Maserati's press meeting traditionally organised by Alejandro De Tomaso in Modena.

Compared to the standard Biturbos, the 2.24v featured restyled front and rear aprons, extended sills, a large tail spoiler and a two-tone paint scheme, along the lines of the Biturbo S. The car later came with an optional active damping system by Koni, and was subject to a restyling in 1991 with a new nose and headlights recalling the Shamal (see 2.24v. II).
