The Porsche 911 (964) models produced between 1989 and 1993 have an overall length ranging from approximately 4250 mm to 4275 mm, which translates to about 167.3 to 168.3 inches. The slight variation in length depends on specific model variants and configurations within the 964 series. This compact length contributes to the car's classic sports car profile, balancing agility and road presence.

The width of the Porsche 911 (964) ranges from 1650 mm to 1775 mm, or roughly 65 to 69.9 inches. This relatively narrow width compared to modern sports cars aids in the car's agility and responsiveness during cornering. The variation in width comes from different trim levels and optional wider rear tires, which can improve stability and traction, enhancing the overall driving experience on both road and track.

The height of the Porsche 911 (964) ranges between 1290 mm and 1310 mm, equivalent to approximately 50.8 to 51.6 inches. This low profile height is typical of sports cars designed to improve aerodynamic efficiency and lower the center of gravity, which helps with handling and stability at high speeds. Slight height differences reflect variations in suspension setups or trim packages.

The curb weight of the Porsche 911 (964) ranges from about 1240 kg to 1470 kg, which is approximately 2734 to 3241 pounds. Maximum permissible weight, considering passengers and cargo, ranges from 1690 kg to 1810 kg, or about 3726 to 3991 pounds. These weights vary depending on the specific model variant and optional equipment fitted. Relatively moderate weight helps maintain the car’s classic sporty performance characteristics.

The luggage capacity of the Porsche 911 (964) is about 90 liters (around 3.2 cubic feet), which is relatively limited compared to modern sports cars. This capacity remains the same even when the rear seats are folded since the 964 features a traditional two-door coupe design rather than an expanded interior space. It’s more suited to light luggage or daily essentials and underscores the car’s focus on performance over practicality.

The Porsche 911 (964) has a ground clearance of 120 mm (approximately 4.7 inches). This low ride height enhances its aerodynamic performance and handling by lowering the center of gravity. However, it means caution is needed when driving over speed bumps, steep driveways, or uneven surfaces, where the car's underside may be more prone to scraping.

Yes, the Porsche 911 (964) fits comfortably inside a standard single-car garage. With a length up to 4275 mm (about 168.3 inches), a width up to 1775 mm (about 69.9 inches), and height up to 1310 mm (around 51.6 inches), it is smaller than most standard garage dimensions, which typically offer at least 5.5 to 6 meters in length and about 2.4 to 3 meters in width. Therefore, the 964 can be parked without issues, allowing enough clearance for opening doors and maneuvering.

Compared to its predecessor, the Porsche 911 (930) produced primarily in the 1970s and 1980s, the 964 generation exhibits modest dimensional changes. While the 930’s length typically ranged around 4365 mm (171.9 inches), slightly longer than the 964’s max 4275 mm (168.3 inches), the 964 offered a slightly wider and more aerodynamic body with widths from 1650 mm to 1775 mm (65 to 69.9 inches), compared to the 930’s narrower stance around 1650 mm (65 inches). Height in the 930 was about 1310 mm (51.6 inches), very similar to the 964. Overall, the 964 focused on modernizing aerodynamics and handling with a more refined, compact profile while maintaining the iconic 911 silhouette.

In comparison to other sports coupes of the early 1990s, like the Ferrari 348 or the BMW M3 E30, the Porsche 911 (964) is relatively compact. The 964’s length of about 4250-4275 mm (167.3-168.3 inches) and width up to 1775 mm (69.9 inches) make it smaller and narrower than many V8 or V12 sports cars of that era, which often exceed 4500 mm (177 inches) in length and have wider bodies. This compactness translates to agile handling and a distinctive driving experience focused on precision. Its lower and more aerodynamic shape compared to broader coupes supports its reputation as a focused sports machine.

The Porsche 911 (964) came equipped with various rim sizes including 7J x 17, 9J x 17, 6J x 16, 8J x 16, 7.5J x 17, and 8J x 18, tying in with several tire size options such as 205/50 R17, 255/40 R17, 205/50 R16, 225/50 R16, 205/55 R16, 225/40 ZR18 among others. Larger and wider tires, like the 255/40 R17 on the rear, enhance grip and cornering capabilities, crucial for high-performance driving. Rim and tire combinations were selected to balance ride comfort, handling precision, and traction, which made the 964 versatile for street driving and track use.
