Hello and the hydraulic car project

Hello, my first post and hope I do it right. I have read alot of posts in the last few days about building contollers and EVs. Great site. I am interested in building a vehicle and am looking at all different types. I ran across an article in either Popular Science or Popular Mechanics (or some magazine) a long time ago, maybe circa 1976, that described a high mileage vehicle using hydraulic drive. The vehicle was a small car of its time, maybe a Pinto or something and was driven by a hydraulic motor that used a gas engine to drive a pump that drove the motor. The key to its efficiency, about 75mpg was that the gas engine, about 15HP, ran at the same speed all the time even at a stop. Running at its most efficient rpm all the time and keeping a hydraulic accumulator charged were the keys to its success. I find it an interesting concept and would like to reread the article if it can be found. Anyone else know of this article? If anyone knows of it or finds it let me know. Any thought on how this would compare to EV? Any hydraulic experts here? I dont know much about hydraulic drives and but will continue to research. Great to be here with like minded people.

regards
