The Alfa Romeo SZ (ES-30 or Experimental Sportscar 3.0 litre) was a high performance limited production sports car/road-concept car built between 1989 and 1991 with partnership via Centro Stile Zagato, Centro Stile Alfa Romeo and Centro Stile Fiat. Robert Opron of the Fiat design studio was responsible for the initial sketches while Antonio Castellana was largely responsible for the final styling details and interior. Only the 'Z' logo of Zagato was kept.
Mechanically and engine-wise, the car was based on the Alfa Romeo 75, production being carried out by Zagato at Via Arese near the Alfa factory in Milan. The thermoplasic injection moulded composite body panels were produced by Italian company Carplast and French company Stratime.
The suspension was modified by Giorgio Pianta, engineer and team manager of the Lancia and Fiat rally works team. The brakes were taken from the Alfa 75 Turbo Evoluzione. A hydraulic ride-height system was added.
The two seater hard roof version also saw a convertible version, the Alfa Romeo RZ (for Roadster Zagato), produced from 1992 until September 1993.
Engine Spec: 3.0 V6 (2959cc), 210 PS DIN (154 kW)
