This makes the decision to go for one or the other quite difficult to make
Choosing between the two very different flavors of top-of-the-range Porsche 911 is apparently redundant if you plan on regular track use as they both seem to post very similar if not identical times. EVO pitted the Turbo S against the track-sharpened GT3 RS, and, well, there was literally nothing in it in terms of laptimes.
Now while the two may be 911s, they’re really rather different in their philosophy: the Turbo S is all-wheel drive, it has more power (580hp vs 500hp), much more torque (up to 750Nm vs 460NM) but also carries around extra heft (1,600 kg dry vs 1,420 kg). Even with its 180 kilos-worth of ballast, it still sprints to 100 km/h in 2.9 seconds, four tenths faster than the GT3 RS.
The latter is supposed to be much more apt on the track, though, but as it turns out, there’s little substitute for outright grunt.
