With a length of 4250 mm (167.3 inches) and width of 1652 mm (65 inches), it is smaller than many modern vehicles, so it doesn’t require any special garage modifications. Its relatively low height of 1280 mm (50.4 inches) also ensures it fits easily in standard garage spaces.

Compared to its predecessor, the 1989 Porsche 911 Speedster’s dimensions remain quite traditional for the 911 lineup. The length, width, and height are in line with earlier models, maintaining the classic compact sports car size that Porsche is known for. However, slight refinements in weight and aerodynamics were achieved to improve performance and driving dynamics, without dramatically increasing the car’s footprint or weight.

Dimensionally, the 1989 Porsche 911 Speedster is quite compact compared to other late 1980s sports cars. Its length of 4250 mm (167.3 inches) and narrow width of 1652 mm (65 inches) make it notably smaller and more agile than many competitors like the Chevrolet Corvette C4 or the Nissan 300ZX, which were typically wider and longer.

The low ground clearance of 115 mm (4.5 inches) enhances the handling and aerodynamic performance of the 1989 Porsche 911 Speedster by lowering the center of gravity, resulting in improved cornering stability and responsiveness. However, this also means the vehicle can be challenging on uneven roads or speed bumps, demanding careful driving on rough terrain or urban environments with steep driveways.

With a curb weight of 1350 kg (2976 lbs), the 1989 Porsche 911 Speedster is relatively light for a sports car of its era, contributing to sharp handling and quick acceleration. The maximum weight capacity of 1600 kg (3527 lbs) means it carries moderate passenger and cargo loads. Keeping weight lower improves braking efficiency and reduces overall inertia, essential traits for performance-focused vehicles like the Speedster.
