The video below claims to be an acceleration comparison between the new 475hp 991 GT3, and the 500hp 997 GT3 RS 4.0 from standstill to around 200km/h. We know it’s not an apples to apples comparison. However, it’s still a pretty fair match considering the new 991 GT3 sports 475 horsepower (25 less than the RS 4.0) but sits ever so slightly lighter on the scales (40 lbs or so) with a curb weight of 3153 lbs. These slight differences make for a pretty close match-up and the new GT3s launch control should even things out. In fact, it seems like it’s the PDK transmission that gives the new 991 GT3 the edge off the line and for the first 100 kilometers per hour or so. It’s not until the top of 3rd gear that the extra horses of the limited edition 997 GT3 RS 4.0 start to show themselves and really pull away.
If this is what the stock 3.8 liter 991 GT3 can do against the 4.0 version 997, how fast will the RS and and other variants be?
