The maximum weight includes passengers and cargo, ensuring safe operation without compromising structural integrity or suspension performance.

The Mazda RX-7 IV comes equipped with 16-inch rims, paired with 225/50 R16 tires. These tire dimensions provide a good balance between grip, ride comfort, and responsiveness. The moderately wide 225 mm tire width enhances traction and cornering stability, while the 50 aspect ratio offers suitable sidewall height to absorb road imperfections without sacrificing handling precision, resulting in a sporty yet comfortable ride.

Yes, the Mazda RX-7 IV fits into a standard residential garage comfortably. With a length of 4285 mm (168.7 inches) and a width of 1760 mm (69.3 inches), it is compact enough for most typical garages, which often measure around 2.4 to 3 meters in width and 5 to 6 meters in length. The relatively low height of 1230 mm (48.4 inches) also poses no clearance issues in standard garage door openings, making it convenient for daily parking.

Compared to the RX-7 III (FD), the RX-7 IV is slightly larger in overall dimensions, reflecting Mazda's aim to add more interior space and comfort without sacrificing the RX-7’s sporty nature. The RX-7 III generally measured about 4265 mm (167.9 inches) in length and 1775 mm (69.9 inches) in width, so the IV gained around 20 mm (0.8 inches) in length and was a bit narrower by approximately 15 mm (0.6 inches). The height remained quite similar but was slightly reduced, enhancing its sleek profile. These subtle dimensional changes improved driver ergonomics and everyday usability while maintaining the car's famed performance.

When compared to similar sports coupes from the early 2000s like the Nissan 350Z, Toyota Supra Mk4, and Mitsubishi Eclipse, the Mazda RX-7 IV is relatively compact and lightweight. For instance, the Nissan 350Z is longer at around 4270 mm (168 inches) but wider at about 1815 mm (71.5 inches), while the Supra Mk4 is generally longer and heavier.

The Mazda RX-7 IV has a wheelbase measuring approximately 2500 mm (98.4 inches). This relatively short wheelbase contributes to the car’s agile handling, allowing for quick directional changes and improving cornering responsiveness. A shorter wheelbase typically results in a more dynamic driving experience but may slightly reduce straight-line stability at high speeds. Mazda’s engineering strikes a balance so that the RX-7 IV offers both nimble maneuverability and sufficient stability for spirited driving.

As a sporty two-door coupe, the Mazda RX-7 IV prioritizes driver engagement and performance over extensive cabin or cargo space. While exact interior volume figures are limited, the dimensions support a snug two-seater layout offering a driver-focused cockpit with supportive seating. Cargo space is relatively limited compared to larger coupes or sedans, generally accommodating small luggage or daily essentials in the rear hatch area. This compact interior design aligns with the RX-7’s ethos as a lightweight, sporty vehicle designed for driving enthusiasts.

The Mazda RX-7 IV stands at a height of 1230 mm (48.4 inches), giving it a very low and sleek stance typical of sports coupes, which aids aerodynamic efficiency and a lowered center of gravity for enhanced handling. Ground clearance is modest, designed to balance sporty appearance with practical everyday usability. This height may demand some caution over steep driveways or uneven surfaces but generally poses no major issues in typical urban and suburban driving scenarios, making it suitable for daily use with sporty flair.

The overall compact exterior dimensions of the Mazda RX-7 IV, including its 4285 mm (168.7 inches) length and 1760 mm (69.3 inches) width, make it easier to park and maneuver in tight urban environments compared to larger sports cars of its era. Its low height at 1230 mm (48.4 inches) and turning radius are optimized for responsive handling and tight cornering, enhancing the driver's ability to negotiate narrow spaces and city streets. These size advantages allow the RX-7 IV to excel both on the track and in everyday driving conditions involving parking and maneuverability.
