I'm just bummed as I had high hopes for the car and the GT4, both have been a little underwhelming vs what the alternative marques are doing.

Power isn't everything. Despite that chart making it look like the 4.0 would be significantly faster than the 991, it isn't. If anything, in a straight line, the 991 is a little quicker. Another example. The 991 GT3 manages to keep up with the 650hp/650tq Z06 in a straight line as well.

Disappointing for me is:
> Output not higher than 500 hp (gap is simply getting too huge vs. Ferrari, R8, Lambos and others)
> Apparently no shorter gear ratios of the PDK vs. regular GT3
> Front + rear spoiler in vehicle color instead of leaving them in carbon-fiber
> Wheel house vents in black plastic and not in carbon-fiber
> Output not higher than 500 hp (gap is simply getting too huge vs. Ferrari, R8, Lambos and others)

At italian briefing dyno hp/torque charts were displayed and the shapes are very very similar to gt3 3.8 ones, so i wouldn't expect any huge modify on stroke side (as it happened with rs 4.0 which produced a big increase in torque at mediums and a flatter curve - peak 460 nm at 4750 vs a 440 peak at 6250 of 3.8 RS...if i remember well).
Let's not forget that in gt3 3.8 power decreases starting from 8.250 rpm, so those last missing (whether confirmed) 200 rpm would't withdraw that much in terms of performances, especially if they worked on engine quickness in getting rpm (better fluodynamic, different balance of cranckshaft, differences in shape and weight of connecting rods), quickness of gearshifts (pdk-s specific sw) driving less rpm fall after each shift, without forgetting lower mass of RS which helps in gaining speed - hence the whole package must considered for a proper evaluation and any improvement in reliability is welcome (also helpful in secondary market of these cars).
I wish they worked at least on ratios of gears we mostly use on track (3-4-5th) assumed final drive didn't change with 310 km/h top speed...but that will be difficult.
Since this pdf is a draft done in january, I expect that the final sheet will contain some amendements.
About wings, as you already underlined it could be a not perfect translation, even about the rear lid, they mention 'black forged aluminium wings' but these are rear wing support which in 997 rs were silver anodized
Cheers
