This new flat 4 has a con rod to stroke ratio of 1.44! Look at this 
carefully, especially the shape of the large end of the con rods. 
Interesting...
Not sure I'd want a ratio like that on a Corvair engine, as the 
acceleration at TDC has to be through the roof on this design, and 
Corvairs don't have the benefit of a 7 main crankshaft.
Still, an interesting read for the tech geeks!!
