1938 · 🇩🇪 Germany · 46 hp
The 1972-era Type 1 Beetle ran a 1.6-litre air-cooled flat-four producing around 46 hp, a layout unchanged since Ferdinand Porsche's 1930s original. By 1972 it briefly outsold the Ford Model T as history's most produced single platform. Rear-engined, cheerful, and globally beloved.
