If you were at least a teenager in the 80s and had a passion for cars you certainly remember the Isdera Imperator. Aside from the cool name, this was one serious car based on the Mercedes-Benz CW311 concept. At its heart is an AMG V8 6.0-liter engine developing 420 bhp (313 KW) which is enough oomph for a 0-62 mph (0-100 km/h) in 5.7 seconds and a top speed of 189 mph (305 km/h).

Initially, the car came out with a 5.0-liter V8 Mercedes-Benz engine and then received a 5.6-liter V8 also from M-B, along with a 5.6-liter V8 tweaked by AMG. The car seen in this video is one of the last produced, powered by the AMG V8 6.0-liter mill.

Featuring gullwing doors and a rear periscope, the Imperator had a fiberglass body on a tubular spaceframe and was created by former Mercedes-Benz design engineer Eberhard Schulz. Only 30 units were made between 1984 and 1993. Mercedes-Benz refused to produce this car but they allowed Schulz to launch it under his own brand, Isdera.

If the DeLorean DMC-12 never existed, this could have easily been the car to star in the "Back to the Future" trilogy.
