Ummm dude, do you know ANYTHING about Audi? The Audi Quattro consists of a TORSEN center diff and electronically controlled open diffs at both ends. It works exactly like the GT-R's ATESSA system with the only difference being that GT-R does a 10/90 split under normal conditions where's Audi generally runs 50/50. FYI the R8 uses a 30:70 split (Top Gear R8 review), the RS4 uses a 40:60 split.
All AWD GT-Rs have a 0:100 torque split if there's no wheelspin.
As for Audi, I was a bit surprised to see "viscous coupling" when I Googled for the R8 (I was looking for the torque split data at the time). As for Top Gear saying its a 30:70 split, I've seen figures quoted from 35:65 to to 40:60 for the R8. Top Gear isn't always accurate.
Granted I prefer the R34 look to all other GT-R's, however 33 was pretty damn far from ugly.
I know beauty is in the eye of the beholder, but the R33 looks a late 90's / early noughties Mitsubishi Galant in some situations (especially when all you can see is the corner indicator and the front wheelarch, its even worse with 2WD R33s as their stock 5 spoke wheels look almost identical to the Galant wheels).
It might be a bit different for me since I see R33s everywhere, but my visual preference has always been R32, R34, KPGC10, and the R33 dead last when it comes to Skyline GT-Rs.
Yes I know that car is already fast but there are plenty of 1000+HP R34's out there making the 450 (not sure if it's exact number)HP R35 is somewhat lacking.

Now that's not fair.
None of those 1000hp GT-Rs are anywhere near factory tune, and there's no way those cars are emissions legal for their year of manufacture, let alone qualifying as an ultra-low emissions vehicle like the R35 GT-R does.
You can't expect Nissan to turn out a road car to compete with people who have no concern when it comes to tractability or road legality.
As I said, the new restrictions won't stop people from modifying...its just taking longer for those mods to come out. The tuners need to learn their way around this engine, and part of that is defeating the engine management.
One of the first thing Ford XR6 Turbo tuners do is modify the ECU, as the car uses two MAP sensors to detect if someone's trying to intercept the reading to adjust A/F (which no-one knew about at first, defeating most interceptor ECU tuners) and brings in a fuel cut if the boost exceeds standard levels (with small margins of error). It just took Ford tuners longer, but if you look at the XR6 Turbo aftermarket the range is huge as the car is very popular as a tuning base.
The RB26DETT has been around since 1989 and so its tuning secrets are a well known and so "easy" these days. But when the were first released, its not like the aftermarket knew about the oil starvation problems due to the unbaffled sump, that the ceramic turbochargers were prone to failure after hard use, and all the myriad of problems the engine has. They're not software restrictions, they're hardware restrictions.
Even the Z-Tune was held to 500hp as Nismo couldn't get the car to make any more power while achieving emissions regulations and keeping it drivable. The "cooking model" R35 is as quick on the track as a hand-built, hard tuned, but completely road legal R34.....which speaks volumes about how good the new R35 is.
