Designer Pierangelo Andreani
The Maserati Biturbo is a sports car introduced by Maserati in 1981. The Biturbo is a two-door, four-seater notchback coupé (of somewhat smaller dimensions than the BMW 3 Series of the time) featuring, as the name implies, a two-litre V6 engine with two turbochargers and a luxurious interior. The car was designed by Pierangelo Andreani, an engineer from the De Tomaso team, somewhat influenced by the design of the newer Quattroporte III (Italdesign Giugiaro), as can be observed on the front fascia.
Export versions came initially with a 2.5L V6, after 1989 it was enlarged to 2.8 Litres, while for Italy a two-litre high-performance version was originally produced (to avoid the 38% sales tax imposed at the time on cars displacing more than 2000 cc). The aluminum 90 degree SOHC V6 engine was roughly based on the 2.0 L Merak engine, itself based on earlier V8 Formula One Maserati engines, designed by Giulio Alfieri (19242002). The carbureted 2.5L engine produced 185 hp (138 kW) and 208 lb·ft (282 N·m) of torque in North American spec and slightly more elsewhere. Fuel injection was fitted in 1987 raising power to 187 hp (139 kW). In 1989 the 2.8L engine bumped power to 225 hp (168 kW) and 246 lb·ft (334 N·m) of torque for North America and 250 hp (186 kW) for Europe.
All Maserati models from the Biturbo's introduction in 1981 until 1997 (except the Quattroporte) were based on the original Biturbo architecture, among them the four-door 420/425 and 4.24v, the Spyder, the Karif, the 228 and 2.24v, the Maserati Racing and the later Shamal and Ghibli II, as well as Maserati Barchetta which used an ultimate version of the V6 engine.
