Default .2GT3 vs .2GT3RS

Ok, I would kill for the RS but just curious what are differences.

Engine? Is it just software to have 20HP more? What are those big air scoops for if engines are the same? Maybe those 20HP is just ram air effect?

I don't buy 0-100sec in 0,2sec faster than GT3. Transmission is the same, gearings are the same. weight same, RS has bigger drag and only 20HP more. You don't cut 0,2sec around 3sec with only 20HP...

To be honest I expected something more from RS for this delta price...

Don’t forget the RS has bigger and stickier fires and Porsche 0-60 numbers are always conservative (for example, GT3 6MT is rated at 3.9 but tested does 3.5 in what appears to be the most egregious example).

RS is not an RS

in other words, compared to a GT3, it isn t a different kind of car

let s clarify, it is different than a 488 or even a GT4RS or, despite the common chassis,
even from a GT2RS,
which I agree are different class of cars

instead the so called RS, as it s real name should suggest
is not an RS but a GT3RS

in facts, as should be, IS a GT3 focused for track use,
even though often confused as a body part extension...

so expect a GT3 with suspensions aero and tires tuning for track, not a huge increase in power band,
which a GT3RS is

Personally, I'm going to keep both. Totally different cars in my opinion. They are both track focused, but the GT3 is a car you can "daily" more in my eyes. The RS is really much more of a weekend cruiser/track car. At least that's just my view.

Well, you do have a point, albeit a little cynical. True, you can modify a GT3 with tires, suspension, heck even a new engine and fenders, but it still will not be a GT3 RS now, will it? And this difference, to those who can afford it, is significant. I'm buying the GT3, because that's what I can afford. If I won the lottery today, I would buy the GT3RS over the "plain" GT3. Or buy a GT2 RS *drool*

Weight reduction shown in the video could account for the acceleration changes. Decreasing a vehicle’s weight by one hundred pounds can generally improve a quarter mile time by a tenth of a second.

I am am not sure why Karl Meltzer or his look-alike are shown running on a trail. Perhaps it means that you have to have endurance while waiting for an allocation.

The engine differences are not just software. There is a different intake plenum and new camshafts (with software updates to use them). There are 20hp more at 200 rpm higher and more peak torque (7 ft-lbs). As for 0-100kph being quicker, don't forget that the RS has wider and larger diameter 21" sticky rear tires that helps with a better launch (together with more power and torque). The additional 20hp has nothing to do with ram-air (that comes in addition to 520hp at high speeds - otherwise RS would have different HP rating in each of its 7 gears). Ratings are made when stationary (no ram-air).

And the gearing is not identical to GT3 - it has a different final drive to offset the larger rear tires - net difference is pretty small though. The greater drag doesn't have much effect up to 100 kph, but it does when going faster (reason the GT3 has 5 mph higher Vmax)

Don't forget better and improved PDK-S versus the 1.2 GT3 version.

where did Porsche describe how the .2 RS PDK-S was better than the .2 GT3?

I saw them describe how much better it was than the .1 RS PDK-S, just didn’t see a comparison to the .2 GT3 PDK-S.

From the evo article, where it says this PDK-S is "bespoke to the RS" under "Engine and Gearbox"

thanks for the pic, however I wouldn’t read that as being better than the .2 GT3 PDK-S, just bespoke. Both 991 RS PDK versions are “bespoke”, because they use different gear ratios than all other 991 models due to the 21 inch rear wheels.

I wouldn’t say so. Me personally would be interested to see all technical differences. But not plain talking like PDK improved or rear wheel steering optimized. There is nothing to improve with PDK even compared to .1 GT3 PDK.

People usually say GT3 and RS arent very different before they actually own an RS.

All those incremental changes do change the character of the car. The sharper suspension, the induction noise, the shorter final drive...
