Thus this confirms what I have said...
Its narrower thus it can fit in narrow streets which for example in capital city of my country it would have pretty much everywhere...
It mobility is a killer, since its whelled thus it has faster acceleration and sterring would result in massive speed drop off...
It both tank and this whelled AFV turret need two seconds for 90 degree turn and AFV can also quickly steer thus further reducing time to aim cannon towards the tank...
Tanks in urban combat are coffins... Vukovar is prime example of that with dozens of tanks being nailed by a.single man... M1A2 or T90 are good againwt insurgents but not against modern military with ATMs penetrating meter of steel.
Tanks can turn on the spot, which is something wheeled vehicles can't.
If tanks, with their superior armor, are vulnerable in an urban setting then I don't see how a lightly armored wheeled TD could possibly be superior: fire power is the same (120mm cannon, turret rotation speed probably similar, not sure if Centauro is as stable if firing to full left or full right compared to MBT), mobility differs primarily in top speed and - possibly - acceleration. Still, I don't see how top speed would matter much in confined urban setting and I doubt dash speed / acceleration would differ much. So, the only advantage left is acces (lesser size, in relation to street width and e.g. bridge carrying capability).
Acceleration
Leopard 2A4: 0-32km/h in under 6 seconds, full (hull) rotation on the spot in 10 seconds (similar LeClerc and Arriete)
M1 Abrams: 0-20 mp/h (32 km/h) in 7 seconds (M1/ IPM1; M1A1), 7.2 seconds (M1A2)
Centauro: 0-70 mph in 30 seconds (one could estimate: ((20*30))/70 = 8.6 sec for 0-20mp/h assuming linear relationship, which in reality would likely be an underestimation as the speed x time is a curve, which would get flatter as time progresses and speed increases)

"Do it right, and the Abrams rocks back on its hull and lunges, at least to 10 mp/h [16.1km/h], which zings by in 1.4 seconds. The 20-mp/h [32.2 km/h] mark passes in 6.4 seconds, at which point seismic sensors in L.A. start twitching. The acceleration slows substantially at 30 mp/h [48.3km/h](15.5 seconds), and the quarter-mile doesn't hit until 32.1 seconds at 38.8 mp/h [62.4km/h = about top speed M1A1 of 62.8km/h]."

Clearly, the heavier MBT is at a disadvantage in that it has a lower top speed, and getting it there takes some effort, but the example does show that the initial acceleration is pretty darn good. Haven't seen any data on that for 24ton Centauro, though, but I doubt a big difference.
For comparison, the M60 Sabra upgrade provides a maximum road speed of 48km/h and accelerates from 0km/h to 32km/h in 9.6 seconds.

As compared to your basic M60A3
Performance, Acceleration 0 to 20 mph in 15 secs
Maximum speed 30 mph, cross-country speed 10 to 12 mph

A T-72 reengined by NIMDA with a 1000hp Perkins CV-12-1000 TCA CONDOR to
T-72M4 CZ standard does 0-32km in half the time the 780hp original did. Looking at the speed x time chart in the (old) brochure, the reengined vehicle does 0 to 38km/h in about 8 seconds (therefore 16 seconds for the original, i.e. very comparable to original M-60)

This goes to show how much faster modern tanks accelerate compared to the previous generation.
