More than a set of wheels.
Honda unveiled the 1300 in October 1968 and launched the 77 series in May 1969. The four-door sedan was intended to combine compact-car economy with much stronger performance than its displacement suggested. The 77 Deluxe sat between Standard and Custom in the seven-model launch range and used Honda's distinctive DDAC air-cooling system.
Look a little closer.
DDAC wrapped the combustion chambers in a second structure that guided fan-driven cooling air. Honda chased even temperatures and high output without a radiator. It was an audacious solution, but its extra castings and airflow hardware reduced the simplicity advantage people normally expect from air cooling.

Honda entered this class without years of conventional sedan habits. Front-wheel drive freed cabin space, the engine revved unusually high, and active safety was linked to acceleration, braking and controllability. The 1300 therefore reads like a bold engineering statement as much as a practical car.
