Apparently, the Hyundai i30, which competes with VW's Golf model, has a very solid steering wheel adjuster, which prompted Winterkorn to state "It doesn't rattle".
Of course, that wasn't just a statement; it was a complaint that needed an explanation from his staff. He called for Klaus Bischoff, in charge of automotive design at VW, and told him: "BMW can't do it. We can't do it. It doesn't rattle!"
Bischoff, caught on the wrong foot, carefully replies that VW had a solution for the rattling steering wheel adjuster, but it wasn't used in production as it was too expensive. Winterkorn, now visibly upset, shot back: "So why can they do it?" There was no answer.
VW did not stop there. Winterkorn is even shown taking measurements of the i30's interior.
