Am I the only one who noticed something wrong with this article. Correct me if I'm wrong but I don't think a 25 lb engine that has 2.4 liters of displacement has 850 cubic inches of displacement! This would be a huge engine and would have to be built of something lighter than titanium to weight only 25 lbs!
In the LA car show video I think the inventor said 25lbs would be the weight of a 1/4 scale version that would be put into autos.
Well read about it.
Yes, you can get 850 ci, depending on how often the pistons fire per revolution.
