1984 Isdera Imperator Dimensions, Size & Specs

The Isdera Imperator has a curb weight of approximately 1250 kg (2756 lbs). This relatively lightweight for a coupe of its size enhances its agility and handling characteristics. The lower weight positively impacts acceleration, braking, and cornering, making it a nimble and responsive vehicle for its time.

With a width of 1835 mm (72.2 inches) and a height of 1135 mm (44.7 inches), the Isdera Imperator has a fairly low and wide stance typical of sports coupes. These dimensions mean the car will fit comfortably inside a standard garage, as typical residential garage doors are usually around 2.4 meters (7.9 feet) wide and 2 meters (6.6 feet) high, providing sufficient clearance for the Imperator.

In comparison to other coupes of the mid-1980s, the Isdera Imperator is relatively compact, with its 4220 mm (166.1 inches) length placing it in the smaller sports coupe category. Many contemporaries, such as the Porsche 944 or Ferrari Mondial, were slightly longer and taller. The wider width and low height of the Imperator give it a more aggressive and aerodynamic form, distinguishing it stylistically and dimensionally from more traditional sports coupes.

Given the overall length of 4220 mm and a narrow, coupe-style width of 1835 mm, the Isdera Imperator is designed primarily as a two-seater sports coupe focused on driver experience rather than passenger comfort or spaciousness. The relatively low height of 1135 mm emphasizes the aerodynamic silhouette at the expense of headroom. Interior space is snug and driver-centric, suitable for sporty driving enthusiasts rather than those seeking a roomy cabin.

The Isdera Imperator, produced from 1984 to 1993, stands out as the primary model of the brand with no direct predecessor bearing the same name. Compared to previous vehicles from Isdera or similar niche manufacturers, the Imperator offers a more refined and cohesive design in terms of size—its dimensions are optimized for sporty performance and aerodynamic efficiency, rather than bulk or excess interior space. This made it a unique and focused coupe in its era.

Compared to other sports coupes from the 1980s and early 1990s, such as the Lotus Esprit or the Porsche 928, the Isdera Imperator is slightly shorter in length but similar in width and height, with a notably lower curb weight of 1250 kg (2756 lbs). While the Esprit and 928 tend to weigh more, the Imperator’s relatively lightweight contributes to its nimbleness. Size-wise, it fits comfortably within the segment, balancing aggressiveness and practicality for its time.

The low height of 1135 mm (44.7 inches) contributes to excellent aerodynamic efficiency and a sporty look but can affect everyday usability. Entry and exit require careful movement due to the low roofline, and taller occupants might find limited headroom and visibility. While ideal for spirited driving and track days, this height can present minor challenges in daily commuting or for those prioritizing easy access and spacious interiors.

The Isdera Imperator features a distinctive design that emphasizes aerodynamics and lightweight construction alongside its compact 4220 mm length and low 1135 mm height. The wide stance at 1835 mm enhances stability. The engineering focuses on performance with a mid-engine layout, low curb weight (1250 kg), and coupe body style, combining aesthetic appeal with dynamic driving characteristics. It stands out as a rare boutique sports car blending unique design with functional performance.

While the Isdera Imperator’s size and weight provide excellent performance and handling, its design prioritizes sportiness over practicality. The compact dimensions and low height can limit passenger comfort and cargo space, making it less ideal for everyday errands or family use. However, for enthusiasts who value exclusivity, driving engagement, and unique styling, the Imperator can be a rewarding daily driver if comfort compromises and limited utility are accepted.
