IRCC, the original 1939 “People's Car” had a 925cc/36HP (0.925L) engine. (1500cc is about 100 cubic inches.) They gradually upped the displacement to about 1800cc in the final Super Beetle.
Driving a 1000cc car on the Autobahn must be a thrill.
One question: will this one come with heat?
Assuming you're not kidding, I'm assuming that one liter refers to the engine displacement. I couldn't help visualizing a pop bottle with wheels, either.
No, it actually refers to the target amount of gas consumption over a specific range. The design goal was to use 1L of gas for 100 kilometers or somesuch; I forget the details.
The prototype actually beat the target.
Actually the first VW bug had a 25hp, 938cc engine, 36 hp didn't come along until years later, but you were close. At any rate the engines weren't very big!
61in^3=1000cm^3
Therefore, 1500cc=92ci approx. You can do a very close approximation by converting hours to minutes and vice versa. 60 minutes equals one hour. So 60ci equals a liter. 2hours equals 120 minutes...so 2 liters equals 120 ci. How many liters equals 105 ci? Well, thats 60 minutes plus 45 minutes...or one and 3/4 hours...or one and 3/4 liters. 1.75 liters=105 cubic inches.
