*N.A.C.C. Horsepower. This formula was used by several manufacturers and license offices in many cities. It represents a comparitive horsepower rating for vehicles. Originally adopted by the A.L.A.M. (Association of Licensed Automobile Manufacturers) which later became the N.A.C.C. (National Automobile Chamber of Commerce). It is not an engineering formula and does not accurately represent the power of an engine. For instance, the stroke of an engine is not included in the formula.

We still have this Autocar and it will be at future shows and events.
