This generation of the Audi RS 4 has a curb weight of approximately 1650 kg (3638 lbs) and a maximum weight rating of 2260 kg (4980 lbs). The curb weight refers to the car's weight with standard equipment and fluids but no passengers or cargo, while the max weight includes occupants and load capacity.

The Audi RS 4 Sedan offers a luggage capacity of 460 liters (16.2 cubic feet) with the rear seats upright. When you fold down the rear seats, the cargo space expands to 720 liters (25.4 cubic feet), providing significant additional room for larger items or extended luggage.

A standard single-car garage usually measures about 2440 mm (96 inches) wide and 5180 mm (204 inches) deep. Given the RS 4's width of 1816 mm (71.5 inches) and length of 4589 mm (180.7 inches), it comfortably fits within these dimensions, allowing plenty of clearance for opening doors and maneuvering inside a typical residential garage.

The Audi RS 4 of this generation rides on 18-inch rims sized 8.5J X 18. The tire specification for these rims is 255/40 R18, which contributes to the car's sporty handling characteristics by providing a good balance of grip, comfort, and performance stability typical for a high-performance sedan.

Compared to the previous Audi RS 4 generation (B5 Avant, produced 2000–2001), which was an avant (wagon) rather than sedan, the B7 RS 4 Sedan is slightly larger in length but narrower and lower in height. The focus shifted to a more performance-oriented sedan stance rather than the earlier wagon’s slightly larger cargo capacity and width.

The Audi RS 4 B7 Sedan is dimensionally comparable to other compact executive performance sedans such as the BMW M3 E46 sedan and the Mercedes-Benz C55 AMG W203. Its length of 4589 mm (180.7 inches) and width of 1816 mm (71.5 inches) places it firmly within the segment standard, offering a balanced mix of agility and space typical of its category.

The RS 4’s roof load capability is rated at 75 kg (165 lbs). This means you can carry rooftop cargo such as luggage boxes or bikes up to this weight safely without negatively impacting vehicle stability or damage. It’s a practical consideration for owners wanting to transport bulky items without sacrificing interior space.

At 1415 mm (55.7 inches) tall, the Audi RS 4 B7 is relatively low-slung for a sedan, which enhances its aerodynamic properties and contributes to a lower center of gravity. This results in better handling and stability at high speeds but might slightly reduce headroom compared to taller sedans. However, it also adds to the sporty and aggressive profile that this performance sedan is known for.

The 2006 Audi RS 4 (8E, B7) sedan is a high-performance vehicle featuring a naturally aspirated 4.2-liter V8 engine producing around 420 horsepower. It offered quattro all-wheel drive for excellent traction, a refined interior, and sporty suspension tuning. It combined practicality with sharp driving dynamics, making it a popular choice for enthusiasts wanting both everyday usability and track-capable performance.
