Built as a test platform to collect data for the next generation of aluminum engines, the 1980 450 SLC 5.0 was manufactured in limited numbers and was an obviously expensive venture for the factory. 1,470 examples were built for road use, just enough for ONS/FIA homologation. Only a fraction were used as competition coupes in various motorsport arenas. Reportedly, only 40 examples were sold new in the United Sates.
Primarily a factory experimental car, this 450 SLC 5.0 was exclusively equipped with the brand new “one year only, all aluminum” 5.0 power plant, delivering 240 Horsepower to the rear wheels. Using the feedback and date received through competition use, an aluminum alloy 5.0 Liter V8 made it into production in 1980, albiet in slightly modified abd with one additional cubic inch of displacement. A stock 450 SLC 5.0 Lightweight Coupe will outperform most contemporary Mercedes, including the 450 SEL 6.9 and even the newer generation’s fastest contenders, the 560 SEC and SL.
The factory plate identifies all of the options that the car was delivered new with, including the colour code 735G (Glasurit Astral Silver), and upholstery code 201 (Black Leather 9028). The codes translate like this:
404: Single seats with orthopaedic front seat backrest, left
405: Single seats with orthopaedic front seat backrest, right
440: Tempomat (cruise control)
466: Central locking mechanism
480: Self-levelling device
502: Outside rearview mirror, on the right
511: Becker Radio Set
581: Automatic Climate Control
584: Window regulators, electric
590: Heat-absorbing glass, wrap-around, heated rear window pane
600: Headlamp cleaning system
682: Fire extinguisher
256: Rear axle with limited-slip differential
355: Antenna used for telephone, on left rear fender
