The BMW 633CS and 635CS, along with their high-performance M6 variant, are iconic coupes that represent a pinnacle of luxury and performance in the 1970s and 1980s. Introduced in 1976, these vehicles were based on the E24 platform, a successor to the popular E9 series 3.0 CSL. The 633CS was powered by a 3.2-liter inline-six engine, while the 635CS received a larger 3.5-liter unit, both delivering smooth power and refined handling. The M6, launched in 1978, boasted a potent 3.5-liter inline-six engine with a distinctive M-tuned exhaust and suspension system, putting it on par with contemporary performance cars from Ferrari and Porsche.

The E24 generation of BMW 6-Series cars were known for their elegant design, featuring a long hood, a sloping roofline, and a distinctive rear end with a rear spoiler. The interior was equally luxurious, offering leather upholstery, wood trim, and advanced creature comforts. The 633CS and 635CS were praised for their comfortable ride, responsive handling, and exceptional fuel economy for their size. The M6 further honed these characteristics, offering a more aggressive driving experience without sacrificing comfort. While production ceased in 1989, these cars remain highly sought-after by enthusiasts for their timeless design, powerful performance, and enduring legacy as one of BMW's most successful grand touring coupes.
