ouch ! Major faux pas on their behalf, and a company with F1 history going way back, I think the Honda S600 was a direct flow on from their GP engines, roller-bearing crank, 4 carbs, DOHC and the engine was canted to the 45 degree angle so you could see there was suppose to be another set of cylinders. Have always admired Hondas engineering and a shame they are not still racing, Merc have turned a winning car into a fader
Volkswagens present focus is the Chinese car market and not the F1. Piech is too smart to pay for Bernies F1 and Volkswagen sponsoring Toro Rosso is a domestic Austrian business among Piech and Mateschitz I guess. Maybe Dürheimer wants to enter the F1, but I doubt Piech and the unions would approve this.
