The reasons for the demise of the brother's relationship have been lost to time. There has been much speculation throughout the years with evidence that it may have been the direction of the company and the types of vehicles that were produced. The Charles Duryea's vehicles were simple and resembled the buggy design of the horseless carriages. Duryea felt that these vehicles were sufficient and needed little improvement. Frank Duryea's cars were the exact opposite. They were large, luxurious, expensive and powerful. Most were touring cars and limousines with a few roadsters making it into production. Production was low with about 100 examples being produced per year.
By 1906 the Stevens Duryea Company had become independent of the J. Stevens Company. Throughout the years it endured bankruptcies and reorganizations partly due to mis-management and escalating competition. In 1915 Frank Duryea left the company over a conflict dealing with the types of cars that were to be built. Stevens-Duryea went out of production in 1927.
This seven-passenger Model Y touring car had a factory price of $4000 and sat atop a 142 inch wheelbase. It is powered by a six-cylinder engine that produced 54 horsepower.Also photographed at :
