There are many unusual features about this car, and its performance is good at all speeds up to its maximum of 70 miles per hour.

Without Differential the Gearless, a Gasoline-Burning Car Having a Steam Engine Operating Direct on Each Rear Wheel The steam engines, bolted to the rear axle housing, are operated by twin control.

There was no connection to the Gearless Motor Car Company, which used the same brand name a few years earlier.
