For both developers this task was their biggest challenge so far at Volkswagen. “It’s a huge deal to further develop the new Polo,” says Rossbach, who is now 31. “The Polo has to be perfect in every respect. It is the leading car in its class.” His Polo partner Horn agrees. “We faced high expectations right from the start. Every boss was going to come to us with an extra question or two.” Both developers always had to keep their eye on the entire Polo – from the USB port on the central console, to the fenders, and on to the platform, which was also completely new. For in its sixth generation, the Polo is switching to the Modular Transverse Matrix (MQB).
