Max Prinzing

Malcolm (Max) Prinzing was a Cum Laude graduate of Lea College, Albert Lea, Minnesota, when he bought a 70 acre farm in Winthrop, Minnesota. It was in the machine shed on that farm that Max built the first Prinzing auto in 1975.

In 1979, Max invented and patented the first engine in America to run on 100% ethanol. Race cars have been running on methanol made from coal tar since 1973. Ethanol is made from renewable vegetation whereas coal and oil are not renewable.

Ethanol is environmentally friendly. It emits no carbon monoxide and will not affect the ozone. It emits pure distilled water

from the exhaust so clean that Max could drink water collected from the end of the exhaust pipe in demonstrations.

Max built a demonstration car dubbed "Spirit of Minnesota" and drove it to Washington D.C. to show that Americans do not

need to depend on gasoline to power our cars. The Washington Post published a photo of the car with then Senator from

Minnesota, Rudy Boschwitz at the wheel. This was 1977!

Today, every automobile built by PRINZING MOTOR COACH will run on ethanol, gasoline, or any combination of the two fuels.

Max is a Vietnam Vet having served in the US Army Rangers in 1968 and 1969.  He was wounded in action twice, once in

Cambodia and once in Vietnam.  Max is married to the lovely Mavis Prinzing and has two daughters and four granddaughters.
