Nash Motors was founded in 1916 by former General Motors president Charles W. Nash who acquired the Thomas B. Jeffery Company. Jefferys best known automobile was the Rambler. Nash enjoyed decades of success by marketing mid-priced cars for middle class buyers.Much of the early success of the company was owed to Charlie Nashs faith in engineer Nils Erik Wahlberg. Wahlberg was an early proponent of wind tunnel testing for vehicles. Wahlberg is also credited with helping to design modern flow-through ventilation, a process by which fresh, outside air enters a cars air-circulating system, is warmed (or cooled), and exits through rearward placed vents. The process also helped to reduce humidity and equalize the slight pressure differential between the outside and inside of a moving vehicle.Nashs slogan from the late 1920s and 1930s was "Give the customer more than he has paid for" and the cars pretty much lived up to it. Innovations included a straight-eight engine with overhead valves, twin spark plugs, and nine crankshaft bearings. The 1932 Ambassador Eight had synchromesh transmissions and free wheeling, automatic centralized chassis lubrication, a worm-drive rear end, and its suspension was adjustable from within the car.
