what year car can they freely test? if so, the STR10 testing would make sense;
they have ALL the data on the original STR10.
they have all the data on the 2017 STR - regarding fat tires, wings, etc.
have somebody simulate and work out the data in mounting 2017+ spec material on a STR10.
and have somebody work out a way to plant the honda engine in there.
use it as a testbed for testing the honda engine.
keep developing and testing the STR13 untill the last moment possible, melbourne.
