2019 M8 a "Porsche turbo killer" - BMW M boss

We're used to car companies keeping their cards close to their chest. We're used to them being coy, refusing to comment on their rivals. That's not the case at BMW M. The upcoming BMW M8 has its sights set on the Porsche 911 Turbo. In fact Markus Flasch, recently-appointed head if BMW M, says it's being described as a "Porsche Turbo killer" in waiting. A bold claim.
