The 1915 Chevrolet Series H lineup carried over both of its models from 1914. These were the Baby Grand touring car and the Royal Mail roadster, both built on the same 104-inch wheelbase. Painted in gray or plum, a Baby Grand cost $875 with a magneto and Prest-O-Lite gas lighting, or $1,000 with full Auto-Lite electricals -- including starter.

While the Royal Mail was descended from the Little, Baby Grands bore no kinship to prior models. Both were billed as "The Product of Experience."

Chevrolet referred to its overhead-valve engine as a "valve-in-head" design, which drew considerable publicity because most rivals were flatheads. Exposed pushrods actuated valves in the detachable crossflow cylinder head. The starter now sat at the rear, operating a ring gear, as in modern engines. Instead of a water pump, it used thermo-syphon cooling. Unlike the Royal Mail, which employed gravity fuel feed, the Baby Grand got a pressurized system.

For 1915, wheelbases stretched to 106 inches, and larger-diameter brakes were installed. Electric starters became standard -- a "first" in the low-priced field. Addition of a deluxe Amesbury Special roadster, with wood or wire wheels, helped bolster Chevy's image.

Just 5,005 Chevrolets were built in 1914, but the total climbed past 13,000 for 1915, earning a $1.3 million profit.
