2002 Alpina Roadster V8 Dimensions, Size & Specs

The curb weight of the Alpina Roadster V8 is 1615 kilograms (approximately 3560 pounds), which represents the car's standard weight including the necessary fluids and a full tank of fuel, but without passengers or cargo. The maximum permissible weight, which is the total weight when fully loaded with passengers and cargo, is 1950 kilograms (around 4299 pounds). These weight figures influence the vehicle's handling, acceleration, and braking performance, highlighting its balance between performance and comfort.

The Alpina Roadster V8, with its dimensions of 4400 mm in length (173.2 inches), 1830 mm in width (72.0 inches), and 1320 mm in height (52.0 inches), generally fits comfortably into a standard residential garage. Most standard garages have interior dimensions of approximately 6000 mm (20 feet) in length and 3000 mm (10 feet) in width, providing ample space for the vehicle with room to open doors and maneuver inside. Its relatively low height also makes it suitable for various residential garage heights, common in suburban homes.

Comparing the Alpina Roadster V8 (2002–2006) to its predecessor, the car typically maintained a similar footprint in terms of length and width but often featured refinements in aerodynamics and styling that influenced effective use of space. The 4400 mm length and 1830 mm width of the Roadster V8 align closely with the earlier model's external dimensions, but improvements in chassis tuning and suspension enhanced handling dynamics. The weight may have seen minor changes reflecting additional equipment or structural reinforcements. These changes contributed to a more refined and performance-oriented vehicle compared to its predecessor.

The Alpina Roadster V8, with a length of 4400 mm and width of 1830 mm, fits well within the typical size range of early 2000s luxury roadsters. Compared to competitors like the BMW Z8 or Mercedes SL-Class of that era, the Roadster V8 is slightly longer and wider, offering a more substantial presence on the road. Its low height of 1320 mm contributes to a sporty, aerodynamic profile typical of performance-focused convertibles. The tire size of 255/35 R20 also suggests a focus on grip and handling, positioning it competitively among similar sports cars.

The Alpina Roadster V8 is equipped with tires sized 255/35 R20. This means the tires have a width of 255 millimeters, an aspect ratio of 35 (the height of the sidewall is 35% of the tire's width), and fit on 20-inch diameter wheels. These large, wide tires provide increased road contact, which enhances grip and stability, especially during high-speed cornering or sporty driving conditions. The low profile aspect ratio also improves handling responsiveness, though it may result in a firmer ride on rough surfaces.

The Alpina Roadster V8 stands at an overall height of 1320 mm (about 52 inches). This relatively low height reduces the vehicle's center of gravity, which positively affects handling by improving stability and minimizing body roll during cornering. The low stance also contributes to aerodynamic efficiency, reducing air resistance and enhancing fuel economy and high-speed performance. Additionally, the low height gives the roadster a sleek and sporty aesthetic.

As a two-seat roadster, the Alpina Roadster V8 is designed primarily for driver and passenger comfort and sportiness rather than passenger capacity. Typically, these roadsters prioritize front cabin ergonomics, offering snug, supportive seats that emphasize driver engagement and control. Interior space is cozy but sufficient for most adults, with an emphasis on a driver-focused cockpit. Rear seating or additional passenger capacity is not a feature of this model, reinforcing its sportscar character.

With a width of 1830 mm (approximately 72 inches), the Alpina Roadster V8 offers a stable and confident presence on the road. This width ensures good stability while cornering and reduces the tendency of body roll. It also allows for comfortable seating and shoulder room for the two occupants. On narrower city roads or tight parking spaces, the wide stance might require more careful maneuvering, but it enhances the vehicle's road presence and high-speed stability, important traits for a performance-oriented roadster.

Weighing in at 1615 kilograms (about 3560 pounds) curb weight, the Alpina Roadster V8 strikes a balance between enough mass for stability and sufficient lightness for agile performance. This weight includes the car ready to drive, without passengers or cargo, factoring in necessary fluids and fuel. The weight affects acceleration, handling, braking, and fuel efficiency. For a car of its power and luxury level, 1615 kg is relatively moderate, helping to ensure spirited driving dynamics while maintaining comfort and refinement expected in this class of roadsters.
