This is exactly what happens in the piece of footage below, which shows the velocity demons duking it out on the circuit. And, as we mentioned in the title, their brawl is drift-sturbed by an Alfa Romeo Giulia Q.Once again, in theory, the Italian sedan shouldn't be here. However, if we take a better look at its performance figures, things change. Sure, with the 2017 Porsche Panamera Turbo having grabbed the Nurburgring sedan crown from the Giulia, the Alfa can no longer brag about its record, but we'll remind you that Q at the end of the badge still allows the 510 PS (503 hp) four-door to go faster round the Nordschleife than the "standard" M4. As for its top speed, this almost rivals the maximum velocity of the 911 R.The three-way track adventure we have here comes from the French aficionados over at auto moto magazine, who have taken the three speed heroes to the Circuit La Ferté Gaucher. Sure, the track might not be too long, but it's certainly technical and it sits just one hour of driving away from Paris.Returning to the 500 PS (493 hp) M4 GTS and the 500 hp 911 R, we could call them opposite machines. That's because the Zuffenhausen vehicle comes to fill the clutch void generated by the GT3 and GT3 RS, while the Bimmer ditches the optional stick shift offered by the "regular" model.Speaking of the 911 GT3 PDK, this is a much closer competitor for the BMW M4 GTS. And if you're looking for a track comparison involving these two toys, you should check out the story we brought you earlier this summer, one that involved sharper driving compared to what we see here.
