ALFA ROMEO RZ ROADSTER ZAGATO NO.064 26,700 ORIGINAL KM An exceptionally rare automobile, representing the final great period of rear-wheel-drive Alfa Romeo sports cars, built by Zagato and powered by the legendary “Busso” V6. An automobile born during an unrepeatable period in Alfa Romeo history The Alfa Romeo RZ – Roadster Zagato represents one of the rarest and most unconventional expressions of Alfa Romeo production during the late 1980s and early 1990s. The car originated from the ES30 – Experimental Sportscar 3.0 litre project, conceived to create a limited-production sports car that was technologically and stylistically radical. The project involved three major Italian design realities: Alfa Romeo Centro Stile, Fiat Centro Stile and Zagato. The ES30 was unveiled at the 1989 Geneva Motor Show and subsequently gave birth to the SZ – Sprint Zagato coupé and, from 1992, the even rarer RZ – Roadster Zagato. The RZ therefore belongs to a particularly significant historical period: the transition from Alfa Romeo's great tradition of front-engine, rear-wheel-drive cars with transaxle architecture to the company's later evolution towards different technical solutions. In this sense, it is one of the final production Alfa Romeo sports cars to retain a technical philosophy deeply rooted in the marque's traditional engineering heritage. The design: Robert Opron, Antonio Castellana and Zagato Although the name Zagato is inseparably associated with the RZ, its design was the result of a more complex collaboration. The first sketches for the ES30 project were developed at Fiat Centro Stile under the direction of Robert Opron, the celebrated French designer known, among other projects, for the Citroën SM and CX. The project was subsequently developed with the contribution of Antonio Castellana, while Alfa Romeo Centro Stile, directed by Walter de Silva, and Zagato were also involved in the programme. The result is one of the most instantly recognizable and radical bodies in Alfa Romeo history: a wedge-shaped profile, high muscular sides, taut surfaces, a set-back passenger compartment and proportions deliberately outside conventional automotive design. The transformation from SZ coupé to RZ roadster was not simply a matter of removing the roof. The absence of the upper structure required structural modifications and reinforcements; the RZ consequently became heavier than the SZ and slightly less performance-oriented, while gaining a completely different character and an even more exclusive personality. Production and assembly were entrusted to Zagato at its Terrazzano di Rho facility, making each RZ the product of a substantially more exclusive manufacturing process than that of an ordinary mass-production Alfa Romeo. Gallery Aaldering+1 The legendary Alfa Romeo “Busso” V6 At the heart of the RZ is the famous Alfa Romeo V6 designed by Giuseppe Busso, one of the most important and recognizable engines in the history of the Alfa Romeo marque. It is a 60-degree V6, longitudinally mounted at the front, with 2,959 cc, 12 valves and single-overhead-camshaft architecture, electronic fuel injection and naturally aspirated induction. In RZ specification, the engine belongs to the 3.0-litre “Busso” V6 family derived from the mechanical architecture of the Alfa Romeo 75 and suitably developed for the ES30 project. Technical sources quote figures in the region of 204–210 hp at 6,200 rpm and 245 Nm at 4,500 rpm; the specification supplied for this particular car states 152 kW. Today, the “Busso” V6 is particularly appreciated by collectors not only for its performance but also for its architecture, throttle response, progressive power delivery and, above all, the unmistakable sound that helped make it one of Alfa Romeo's iconic engines. Engineering rooted in Alfa Romeo's sporting tradition The RZ is not simply a roadster fitted with an Alfa Romeo engine. Its technical architecture is derived from the Alfa Romeo 75, incorporating elements developed from the experience gained with competition versions. The transmission uses the characteristic transaxle layout, with the five-speed manual gearbox positioned at the rear together with the differential, contributing to weight distribution. At the rear is the sophisticated De Dion axle, while the front suspension is independent. The braking system uses disc brakes, with ventilated discs at the front. Power-assisted steering is included in this car's specification. This configuration gives the RZ a very distinctive technical character: a longitudinal front engine, rear-wheel drive, rear transaxle and De Dion rear axle represent a combination that has become exceptionally rare.
