Mercedes Benz Koenig Specials 1000SEL 500SEL 560SEL V8 Sound Japan.
Koenig created the first kit for the 500 560 SEC SEL in 1985, and the second in 1989. The car not only had more prominent bumpers with larger air intakes, but was also wider and more flared, reminding the Ferrari Testarossa cues of those years. The front fenders were significantly wider, giving rise to a protrusion along the entire length of the car, which went up into the rear fender area and also had massive intakes in the wheel areas there. But there were also versions without incisions in that back area.
These strongly flared rear wings evolved with a line that drifted towards a trunk spoiler, the rear bumper also being wider and starting from the wider area of the rear wings. Inevitably, the wheels were also wider, to better transfer the increased performance to the asphalt.
Koening had applied an Albrex mechanical supercharger to the M117 engine, with an intercooler, which increased the power of the V8 from 268 hp to 400 hp!
All this package came with BBS wheels, modified suspension and bigger brakes. Naturally, the exhaust system was also modified, to better emphasize the new sound of the supercharged V8 engine.

Koenig Specials GmbH (known widely as Koenig) is a German tuning house based in Munich that specialised in modifications to European luxury cars but gained notability in the 1980s and 1990s for their performance modifications to Ferraris. Some of its most notable works included a twin-turbo Ferrari Testarossa with extensive body modifications that made it resemble a Ferrari F40 (known as the Koenig Competition and in revised form Koenig Competition Evolution) that produced up to a claimed 1,000 PS DIN in “Evolution“ guise, a highly unusual output for cars at the time, as well as the 850 PS DIN Ferrari F50. Koenig also entered into automobile production with its road-going version of the Porsche 962 known as the Koenig C62, therefore becoming the first road-legal Group C-based car
