SCIENTIFIC LIGHT WEIGHT HOLDS THE ROAD APROMINENT Aeronautical Engineer, recently employed by the United States Govern ment, writes to the Franklin Company: "Isn't it remarkable how the idea sticks in some people's heads that a heavy car holds the toad better ? They don't seem to know that unsprung weight is the principal factor to be con sidered. By reducing this unsprung weight to the minimum in the new Franklin, you have a car that hangs to the roadbetter than anything I have ever ridden in. "P. S. -Problem: Since I got 15,000 miles out of my tires on my old Franklin, weighing 2,600 pounds, how many miles will I get with my new Franklin, weighing 2,280 pounds?" THERE is much in this question of scientific light weight that the average motorist does not seem to grasp. For example, the light, flexible car may be stronger than a rigid, heavy car. It is free from so much dead weight. Picture two cars side by side : one weighs approximately 2,200 pounds, the other 3,000 pounds. Each is designed to perform the same task-carry an average load of five people, about 750 pounds of live weight. Now remember that dead weight is the kill ing thing on automobile mechanism. That's why the average Truck is pounded to pieces. Your light, flexible car starts on its work free from nearly a thousand pounds of dead weight. Wherever it goes and for all its life, it moves free from that sagging, grinding load. Your heavy car, from the minute it starts and as long as it runs, carries a thousand extra pounds of dead weight-an excess nearly twice its average live load. Think what that does to the tires! Think what it costs in gasoline! Think what it means in repairs and depreciation! And what does it give you in return? More road ability ? No! Greater average speed from place to place ? No! More comfort and reliability? No! Any rough road tells the story! Every obstruction raises the heavy, rigid car bodily off the road-a constant hammer ing action that affects alike the car and its passengers. While the Franklin,with its light unsprung weight and full elliptic springs, holds its wheels to the road. Vibration and bump are absorbed by flexible construction. The body of the car, with its passengers, rolls along with easy, unbroken motion. Keeping the road is a matter of balance and light unsprung weight. No matter what your horse-power, a Franklin will pass you, over any thirty miles of winding country road. It will leave you when you slow down at the first sharp curve or rough place. And the next time you see it, it will be rounding the curve ahead, hug ging the inside of the track at thirty miles an hour. Try to follow it with your heavy car, and your rear wheels will skid clear across the road and over into the ditch, if you are not careful. Whereas the Franklin, with its scientific light weight, its resiliency and easy. rolling caster action, holds to its course. Watch any Franklin owner handle his car. He will tell you it is the easiest, simplest car he ever drove-with a comfort, safety, and economy that you get only from this Scientific Light- Weight Car.
