I saw a new Blue 2017 Focus RS in the New Forest near Beaulieu yesterday, it was turning into a road I was just pulling out of. When it turned into the road the driver put his foot down and it backfired, popped and banged just like a rally car which suprised me. Do the new ones have anti-lag as standard now which is what it seemed like?

 

no there are pops from the exhaust programmed in by ford in sport mode
