The popular saying 'one man’s loss is another’s gain' played out perfectly back in the days as the CW311 show car abandoned by Mercedes was later produced by Isdera as the awesome Imperator 108i. The Isdera AG which in English stands for “Engineering Company for Styling, Design, and Racing” is a specialty carmaker and design service provider with headquarters in Saarwellingen, Germany. Originally founded in Leonberg in 1982, Isdera is the brainchild of German automotive designer Eberhard Schulz.

In 1984, Isdera launched the production version of the Mercedes-Benz CW311 concept car which was originally designed for Mercedes by Schulz while he worked as a designer-engineer for the German automotive company. The CW311 prototype was proposed as the successor to the Wankel-powered C111 before the project was terminated by Mercedes. Nonetheless, having earned the right to produce the car from Mercedes, Schulz launched the production version of the sports car as the Imperator 108i through Isdera.

Designed by German car designer and Isdera founder Eberhard Schulz, the Imperator 108i is built as a 2-door coupé constructed with a fiberglass body on a tubular steel spaceframe chassis. One of the most exotic cars of its era, the German sports car was launched with fixed unit headlights and a more conventional taillight.

Since the Isdera Imperator 108i is developed as an evolution of a Mercedes show car, Isdera again sought help from Mercedes to power the project. Therefore, the original Imperator 108i is powered by a 5.0-liter Mercedes-Benz M117 V8 engine.

However, subsequent versions received more powerful Mercedes-Benz engines such as the 5.6-liter Mercedes-Benz M117 V8, as well as the 5.6-liter AMG V8 and the 6.0-liter AMG V8. The Isdera Imperator 108i notably received the newest corresponding Mercedes engines as they were produced.

Relying on the firepower from Mercedes engines, Isdera was able to provide the Imperator 108i with adequate juice to compete with the best cars of its era. The first in series of the Imperator 108i is fitted with a 5.0-liter Mercedes-Benz M117 V8 engine with an output of 300 horsepower.

Subsequently, more powerful engine options like the 5.6-liter Mercedes-Benz M117 V8, a 5.6-liter AMG V8, and 6.0-liter AMG V8 were adopted, and they provided an increased power of 390 horsepower and more.

The power generated from the assortment of potent Mercedes engines fitted on the Imperator 108i is sent to the rear wheels of the awesome sports car through a 5-speed ZF manual transmission for the most incredible performances.

Notably, the 5.0-liter engine option with the 300 horsepower out can propel the car from rest to 60 mph in five seconds, with a top speed of 176 mph. Subsequent units were fitted with the more powerful 390 hp-producing engines, which earns them greater performances.

Keen observers and anyone familiar with the Imperator 108i must have noticed the siren-like bulge on the roof of the sports car. Contrary to what it looks like, it’s definitely not a siren, but an awesome innovative feature deployed on the Imperator 108i for a better view of the surroundings.

To be precise, this feature is a rearview periscope, and it was adopted in place of the conventional rearview mirror found on most cars, giving the driver a proper view of the back.

The gullwing door is an ingeniously designed car door style that was pioneered by the Mercedes-Benz 300 SL, initially as a race car in 1952 and as a production car in 1954. Also known as a falcon-wing door, in this type of style, the door is hinged at the roof rather than the side of the car.

Notably, the “gullwing” name was coined from the door’s resemblance to a seagull’s wings when left open. Hence, having adopted several features from the Mercedes brand, the Imperator 108i also featured gullwing doors.

The Isdera Imperator 108i has all the attributes of a unique and rare luxury car. One of such attributes is its low production number as well as its quite short production reign. Limited production often makes cars extremely rare and more valuable, and as such, they become a prime target for collectors due to their high value.
