As seen on Carscoops, the new GT3 RS receives pretty much the same styling changes as its less hardcore sibling, the 991.2 911 GT3. These changes include the updated angular front intakes in the bumper and new tailights at the rear. The front bonnet also receives new small ducts that should aid in cooling.
It is reported in the article that its reworked 4.0-litre natural-aspirated engine could have a bump in power to a total of 520bhp. It is expected to do the century sprint in 3.2 seconds and go past 310km/h when given enough room.
