I sell beautiful Maserati Spider BITURBO - 2. 0 V6 223 HP - RED CORSA. Leather/ alcantara interior. Kept by an amateur. New hood. Engine distribution recently done. The overall condition of the car is really good. Original first paint. Characterized by a classic and elegant 3-box coupé line (whose paternity is due to the in-house design of Pierangelo Andreani, Maserati's Capo Stile, although influenced by Giugiaro, designer of the 1979 Quattroporte from which the Biturbo takes its inspiration[1]) and a classic technical layout (longitudinal front engine, rear-wheel drive, independent front suspension, swing-arm rear suspension and a braking system with discs front and rear), the "Biturbo" was launched in 1982.
The engine, a carburettor-powered twin-shaft V6, was derived from that of the Merak, from which it differed in the number of valves (3 per cylinder instead of 2) and the turbocharging system consisting of two turbochargers, one per bank (hence the name Biturbo). Engine of a 1985 Maserati Biturbo 2. 5-litre with 18 valves and twin-turbo from IHI[2]. It was one of the first road cars to use a multi-turbo system[3] To cope with the planned production of 35 examples per day, only the engine and suspension were assembled at Maserati in Modena; the rest of the car was produced at Innocenti in Milano Lambrate. 1984 saw the introduction of the Biturbo S, of which 1. 038 examples were built up to 1986, with a 2-litre engine boosted by the adoption of an intercooler that increased the pressure of the turbochargers to 205 bhp, 4 disc brakes, an interior with different trim with Missoni fabric for the seats, different instrumentation and sportier livery with black honeycomb grille, burnished window frames, forged rims, NACA-type air intakes on the bonnet (to cool the intercoolers), rear wing, black bumpers and side fascias with miniskirts.
Also in the same year a turbine management system called M. A. B. C. (Maserati Automatic Boost Control) was introduced on all versions. A 1986 Maserati Biturbo 420i In 1985 the Biturbo 425 and the Biturbo Spyder were also presented. The former was a four-door saloon variant based on the stretched coupé floorpan, while the latter was a two-door spider based on the shortened floorpan, the brainchild of Zagato.[4] Both were powered by a 192 hp 2. 5-litre V6 biturbo. A few months later, the Biturbo 420 and Biturbo Spyder 2. 0 were made available for Italy only, powered by the V6 with a displacement reduced to 1996 cm³ and an output of 180 hp. 1986 also saw the introduction of the Biturbo 420 S, with cosmetic variants similar to the coupé S and a 205 hp engine. Only 2810 units of the 420 and 254 of the 420 S were produced before the introduction of the new engines. In 1987 all engines adopted the Multipoint electronic injection system, resulting in smoother running as well as a slight increase in power, but losing the verve of delivery typical of carburettor engines: 187 hp for the Biturbo 2. 0i (coupé and Spider)[5] and Biturbo 420i, 220 hp for the Biturbo 2. 0 Si and Biturbo 420 Si, which also adopted wider wheels of the same diameter (7jx14), and 196 hp for the Biturbo 2. 5i (coupé and Spider) and Biturbo 425i. In 1988 a restyling by designer Marcello Gandini[6] revolutionised the range. All versions adopted a softer front end, new bumpers, different rims, new interiors with changes to the dashboard, seats, door panels and considerably improved trim. The engines were revised or unreleased: at the base was the 1996 cm³ three-valve-per-cylinder injection V6 biturbo with 223 hp, which powered the Biturbo 222 (coupes), Biturbo 422 (saloons) and the Spider 2. 0i.
