Testing Chalmers Chasses on electric dynamometers. Drawn from lzfeby II. L. Grout The $100,000 Chalmers Hill Most automobiles are tested by driving over ' pavements and country roads. Good tests in their way, but not scientific. Chalmers cars used to be tested that way. Several scores of expert drivers took chasses out for a long grind over country roads. Most cars were well tested. It depended on the driver. "The element of human error is too great," said the Chal mers efficiency engineers. "We need a scientific hill test." From this idea grew the Chalmers electric dynamometer test. Completed chasses are set in steel frames. Great chains are fastened to the rear wheels and to giant dynamos. Running under their own power, the motors work against electrical resistance. Accurate instruments measure the horsepower developed by the motors. Expert mechanics judge the fitness of every working part for long road service. We know the power of Chalmers motors, for the big dynamometer measures it exactly. We know the strength and silence of Chalmers trans missions, clutches, rear axles, for they work in the dynamometer test exactly as they do on the road. The 24-hour test chart of each Chalmers chassis is a record of scientifically measured work-with every chance of human error eliminated. It cost the Chalmers Company over $100,000 to install the dynamometer test; to guarantee to every Chalmers owner that his car is as powerful, as smooth running, and as sturdy as every other car of the same model. But that $100,000 test has saved users of Chalmers cars many times its cost in repair bills eliminated; in continuous service; in satisfaction. The "$100,000 Chalmers hill" proves all Chalmers cars real "Quality First" cars by scientifically measuring their capacity for work and endurance. When you buy a Chalmers you know it will do all we claim. Write for Chalmers "Doings" Number 55 which tells all about Chalmers "Quality First" cars.
