It was intended to be the successor to the Imperator 108i, but due to financial constraints, the company went bankrupt, and only one prototype was completed.

The car has handbuilt fibreglass body work on a tubular steel spaceframe chassis and has 18-inch gold BBS alloy wheels fitted with tyres measuring 255/35 ZR18 at the front and 295/35 ZR19 at the rear.

[3] The 112i had advanced technologies at the time, including gull-wing doors, a gull-wing engine cover for easier access to the engine, a velocity sensitive chassis developed in collaboration with BBS and Bilstein which lowered the car by 76 mm (3 in) at high speeds, an active suspension system and an electronically controlled airbrake.

The airbrake raises in an upright position while braking, acting as a wind deflector to help slow the car down (similar to a parachute).

The dials and other instrumentation (excluding the steering wheel which was from OMP) were from Mercedes-Benz and the speedometer read up to 400 km/h (249 mph).

[4] Isdera planned a limited production run of the 112i like its predecessor and quoted that each car would take six months to complete.

The company was then bought by Swiss investors, under whom Schultz completed the car in order to make it driveable on the road.

Schultz withdrew from the project over a dispute on proposed design changes and later a re-emerging Isdera would also deny its existence.

On the exterior, the updated car had conventional side-view mirrors and had silver five-spoke Mercedes-Benz alloy wheels instead of the gold BBS units.

[6][9] The Isdera Commendatore 112i was featured in the 1997 Electronic Arts racing video game Need for Speed II.
