The X-Type AWD with the mechanical diff and viscous coupling (to 2004) is a very well ballanced drivetrain. A bit tail happy, this is why fun to drive, significantly safer and better than rear wheel drive cars, without the too boring and natural drive feel like thorsens 50-50%.
The overall weight distribution is too front heavy.
The car should have had a torsen rear differential with the automatic transmission, and a viscous coupling with manual transmissions.
TorsenI [quattro] isn't 50/50 when cornering. It is roughly 25/75.
Alternatively, Jaguar could have used a Torsen3 center differential: 45/55 +/- 15% for 60/40 to 30/70
Jaguar now has a new PTO system for their rear drive vehicles, XK XJ.
Nothing new, only offered with supercharged 3.0 V6.
Correction XF, not XK.
The torque split of 40/60 is at the center differential.
To get the power to the rear, three gear meshes are required + the support bearings of the longitudinal driveshaft.
The resultant power split is closer to 45/55.
The X-type can be a little tail happy, but that could be fixed by installing a Quaife or torsen in the rear differential.
