1990 Alfa Romeo SZ Dimensions, Size & Specs

The Alfa Romeo SZ has a curb weight of 1260 kg (approximately 2778 lbs), which represents the weight of the vehicle with all standard equipment, fluids, and a full tank of fuel but without occupants or cargo. The maximum weight, also known as the gross vehicle weight rating (GVWR), is 1430 kg (about 3152 lbs). This figure includes the vehicle’s own weight plus the allowable maximum load with passengers and cargo. The relatively light curb weight contributes to the car's agile handling and sporty credentials, while the maximum weight ensures safe and efficient operation within designed limits.

The Alfa Romeo SZ offers a modest luggage capacity reflecting its sports coupe design. With the rear seats in their upright position, the trunk provides 68 liters (approximately 2.4 cubic feet) of storage space, suitable for small bags or daily necessities. When the rear seats are folded down, the available luggage capacity expands substantially to 350 liters (around 12.4 cubic feet). This increase allows for better accommodation of larger items and greater flexibility in cargo transport despite the car's compact size. This dual-capacity setup is practical for sports car owners needing occasional extra cargo space.

The Alfa Romeo SZ is equipped with two tire sizes to optimize its performance dynamics. The front tires measure 205/55 ZR 16V, while the rear tires are 225/55 ZR 16V. These specifications indicate 16-inch diameter wheels fitted with high-performance radial tires ('ZR' denotes a Z-speed rating suitable for high speeds, and 'V' represents a speed rating up to 240 km/h or 149 mph). The wider rear tires (225 mm) provide better grip and stability at the rear axle, matching the car's rear-wheel-drive layout. The tire profile (aspect ratio of 55) balances responsive handling with ride comfort, essential for a high-performance coupe like the SZ.

The Alfa Romeo SZ's compact dimensions mean it easily fits within a standard residential garage. Given the SZ’s length of 4060 mm (159.8 inches or roughly 13.3 feet), width of 1730 mm (68.1 inches or roughly 5.7 feet), and height of 1310 mm (51.6 inches or about 4.3 feet), it occupies less space than many contemporary larger vehicles. Standard residential garages typically offer at least 6 meters (approximately 19.7 feet) in length and 3 meters (roughly 9.8 feet) in width, providing ample room not only for parking but also for opening doors and additional storage. Thus, owners can expect no issues fitting the SZ into a typical garage space.

The Alfa Romeo SZ is a unique limited-production model without a direct predecessor bearing the same name, but it can be compared to other Alfa Romeo sports coupes like the Alfa Romeo GTV6 from the 1980s. Compared to such earlier models, the SZ is slightly more compact, with a length of 4060 mm versus the GTV6, which measured approximately 4360 mm. The SZ’s width is narrower at 1730 mm compared to some predecessors, but its low height (1310 mm) and aggressive stance reflect a sharper, sportier design focused on performance and handling. This numerical comparison underscores the SZ’s purpose as a specialized sports vehicle, distinct from the more conventional touring coupes Alfa Romeo had produced.

When placed alongside other sports coupes of the late 1980s and early 1990s, such as the Porsche 924/944 or the BMW E30 coupe, the Alfa Romeo SZ holds a distinctive position both in size and design. Dimensionally, the SZ’s length of 4060 mm is slightly shorter than these vehicles, with the Porsche 944, for example, stretching around 4387 mm and the BMW E30 coupe close to 4451 mm. The SZ is narrower and lower, contributing to its aggressive, aerodynamic shape and a purist driving feel. Its design is notably angular and futuristic compared to the smoother lines of contemporaries. This compact yet aggressive footprint, coupled with a lightweight curb weight of 1260 kg, sets the SZ apart in a niche market catering to driving enthusiasts seeking exclusivity and sharp handling.

The Alfa Romeo SZ’s compact size and sporty character are strongly shaped by its angular, minimalist design and engineering choices. The limited length (4060 mm) and low height (1310 mm) contribute to a streamlined silhouette with low wind resistance and a commanding presence. The SZ’s body was designed by Zagato, featuring sharp edges and flat planes that were uncommon among contemporary sports cars, emphasizing lightweight construction and aerodynamic efficiency. The narrow width of 1730 mm aids in reducing frontal area while allowing sufficient stability at high speeds. Lightweight materials and a rigid chassis paired with the car’s compact footprint make for a responsive and nimble driving experience, which was a hallmark of the SZ's appeal.

Yes, the Alfa Romeo SZ is regarded as a rare and highly collectible car. Produced in a limited run between 1989 and 1991, only around 1,036 units were made, which adds to its exclusivity. The SZ is notable for its unique design by Zagato, limited production numbers, and its distinctive engineering, including a powerful V6 engine paired with advanced suspension for its time. Enthusiasts and collectors prize the SZ for its combination of Italian styling, rarity, and driving dynamics. Its particular blend of avant-garde design and performance heritage from Alfa Romeo makes it an iconic and sought-after model among collectors, appreciating both its historical and aesthetic value.

While the Alfa Romeo SZ does not have a direct predecessor, it can be compared to earlier Alfa Romeo coupes like the GTV6 in terms of technical evolution. The SZ incorporates a 3.0-liter V6 engine derived from the Alfa Romeo 75, tuned for higher performance, paired with a sophisticated suspension setup aimed at improved handling and cornering stability. Unlike the GTV6, which had more conventional styling and engineering, the SZ features a much stiffer chassis and lightweight body panels designed by Zagato, making it more agile and focused on driver engagement. Additionally, the SZ’s limited production and specialized engineering differentiate it from other Alfa Romeo coupes, placing it as a more exclusive, performance-oriented model within the brand’s lineup.
