The curb weight of the Lexus SC I ranges from 1595 kg to 1640 kg (3516 to 3615 pounds), depending on the specific model and equipment level. The maximum gross vehicle weight is 1875 kg (4132 pounds). This weight range positions the SC I as a relatively heavy coupe, reflecting its solid build and luxury features. The weight contributes to its stable and composed driving dynamics, while the maximum weight indicates the total load capacity including passengers and cargo.

The luggage capacity of the Lexus SC I is 265 liters (approximately 9.4 cubic feet). For a luxury coupe, this is a reasonable amount of cargo space, making it suitable for daily errands, weekend trips, or golf bags and luggage for a two-person outing. While it’s not as spacious as larger sedans or SUVs, the trunk volume balances sportiness with practicality, accommodating typical storage needs without compromising the vehicle's sleek silhouette.

Yes, the Lexus SC I fits comfortably into a standard residential garage. Typical garage dimensions in many regions are at least 2400 mm (7.9 feet) wide and 4800 mm (15.7 feet) deep. With its length of approximately 4850-4860 mm (190.9-191.3 inches), width of 1790 mm (70.5 inches), and low height of about 1330-1340 mm (52.4-52.8 inches), the SC I easily accommodates these measurements. Its low height further helps with clearance in garages with typical ceiling heights.

The Lexus SC I was the first generation of the SC series, introduced in 1991, so it did not have a direct predecessor under the Lexus brand. However, it was based on the Toyota Soarer platform (Z30), which was more of a luxury grand tourer coupe in Japan. Compared to the Toyota Soarer, the Lexus SC I shared similar dimension traits but was marketed towards a more upscale segment outside Japan, featuring refined luxury and some styling changes. Its size balanced sporty coupe proportions with grand touring comfort.

In comparison to other luxury coupes from the 1990s, such as the BMW 8 Series (E31) or Mercedes-Benz SL (R129), the Lexus SC I is somewhat longer but similar in width and height. For example, the BMW 850Ci of the era measured about 4825 mm in length and 1840 mm in width, while the Mercedes SL ranged shorter in length but wider. The Lexus leaned towards a design that emphasized sleekness and lower height, contributing to a sporty yet comfortable grand touring presence that compared favorably in styling and size to its German rivals.

The Lexus SC I typically comes equipped with 16-inch rims, paired with tire sizes of 225/55 R16 or 225/55 R16 V. These specifications support a good balance between ride comfort and handling performance, suitable for a luxury coupe with sporty ambitions. The 225 mm tire width offers adequate grip and stability, while the 55 aspect ratio provides a ride height that maintains both road feel and comfort.

The Lexus SC I's dimensions contribute to a comfortable grand touring experience, especially in the front seats. With a length of around 4850 mm and width of 1790 mm, the coupe provides ample shoulder and legroom for front passengers, though rear seating is more limited as typical in two-door grand tourers. Its height of approximately 1330-1340 mm offers a low center of gravity, enhancing driving dynamics but slightly reducing headroom compared to taller vehicles. Overall, it balances sporty cabin space with reasonable comfort.

With a curb weight between 1595 kg and 1640 kg (3516 to 3615 lbs), the Lexus SC I is relatively heavy for a coupe, reflecting its solid construction and numerous luxury features. This weight contributes positively to stable highway cruising and a comfortable ride, minimizing harshness and improving noise insulation. However, a higher weight can reduce fuel efficiency and potentially dampen acceleration compared to lighter sports cars. Nevertheless, the Lexus SC I was muscled by robust V8 engines, ensuring ample power to counterbalance the weight.

Throughout its production from 1991 to 2001, the Lexus SC I underwent minor updates and refreshes. Early models launched with a focus on luxury and smooth styling, blending sharp coupe lines with aerodynamic subtlety. Later years saw improvements in safety features, interior refinement, and updated options packages, including enhancements in sound insulation, navigation systems, and comfort amenities. The design remained true to its elegant, understated profile, emphasizing a luxurious grand tourer ethos instead of aggressive sports styling.
