If there is a "basic inherent unsolvable design flaw" then why have so many people who have driven their demonstration vehicles been so impressed ? And why have Aisin and ZF recently become licencees ? And why are BMW/Getrag still working towards a production model ? And why are Ford still talking to TRK ? And why did GM and BMW declare IVT as concept-ready ? And why has Dick Elsy taken up the post of CEO ?
Please don't try to criticise TRK for the quality of its product, which is its main strength.
