Eberhard Schulz, who formerly worked as a design engineer for Mercedes-Benz,
headed an engineering company that designed the CW311 concept in 1978.
The car was built by one of the German Mercedes tuning firms B+B.
With no interest in putting the CW311 into production itself, Mercedes-Benz allowed Schulz to produce the vehicle in 1984 under his own brand Isdera as the model Imperator 108i, and with the Mercedes star badging on the front grille
(later replaced with Isdera flying eagle badges).
The original Imperator 108i featured 5.0 L (5,000 cc) Mercedes-Benz M117 V8 engine
which gave the vehicle a top speed of 176 mph (283 km/h) and an acceleration of 0-60 mi (97 km) in 5.0 seconds.
As Mercedes-Benz developed more powerful V8 engines, they were used in the Imperator 108i.
Later engines included a 5.6 L (5,600 cc) Mercedes-Benz M117 V8, a 5.6 L (5,600 cc) AMG V8 and a 6.0 L (6,000 cc) AMG V8,
with both AMG engines featuring advanced 32-valve cylinder heads.
The Imperator 108i featured a rear-view periscope, creating a bulge on the roof. It also featured gullwing doors.
Production ended in 1993 with a total of 30 examples produced,
two of which were exported to Japan. (wikipedia)
