The Mercedes-Benz W114 and W115 are the internal designations Mercedes-Benz used for a generation of front-engine, rear-drive, five-passenger sedans and coupés introduced in 1968, with three-box styling by Paul Bracq — succeeding the W110 models introduced in 1961; and manufactured until model year 1976, when the W123 was released.
W114/W115s were distinguished in the marketplace by nameplates relating to their engine size. W114 models featured six-cylinder engines and were marketed as the 230, 250, and 280. W115 models featured four-cylinder engines and were marketed as the 200, 220, 230, and 240, with diesel models carrying a D designation, as distinct from gasoline/petrol models.
When Mercedes introduced the W114/115 in 1968, they marketed sedans in two size classes (W114/W115 and S-Class) and marketed the W114/115 range as New Generation Models, ultimately the only model of the new generation. Mercedes used a '/8' on the W114/115 ID plates, indicating their 1968 launch year, giving rise to their '/8' or 'slash eight' nicknames — and the German nickname Strich Acht, loosely translated into English as stroke eight.
