So say's Autocar. Same chassis and interior. Compared to the current RRS that is Disco based, this could make the new, no doubt, lower cost RRS a more interesting proposition?

That would be interesting if true, a real RRS for the first time.  2021 P400 Silicon Silver AB

Whilst I'm sure they'll share as much as they can underneath, they're going to be different cars for different markets.

I think the most significant change to the current RRS is that rather than being 2/3rds Disco the new RRS will be 2/3rds FFRR, which I expect will change it's character somewhat from the current model. Also, according to Autocar they are reintroducing the TDV8 to the RRS. Only a test drive will tell. MY23 D350 HSE

Having come from an RRS to a RR they are both excellent but very different vehicles.

LR won't produce something that is a cheaper scaled down version it will have its own distinct manner.

The sport, I would venture, will maintain the road bias it has. The 5.0 SC defies the laws of physics. Watch the comparison video between the 4.2 and the 5.0 or the Nurburgring lap to see what I mean.

The RR will also maintain its position of simply the world's most resplendent way to traverse a continent be it via pavement, track, or river...!

Which is the best...?

The RRS is superb but the RR is just exquisite...

The Auto-Express item on this also states to expect at least a 10% price hike over current RRS models.................. where do LR think we are all getting all this money from to buy their cars? 2018 Mini Countryman Cooper S E All4 PHEV in Melting Silver - it’s whisper quiet in EV and polluter modes

Allan, you are correct that the current RRS is very different to the FFRR. I tried a RRS before buying my first FFRR and I am now on my third FFRR. However, the main reason the current models of the RRS and FFRR are so different is because they are based on different floor plans and structures. This will not be the case going forward according to AutoCar, so their driving experience could be much closer in future. Although I doubt the interior will provide a similar experience even if just for reasons of space and seating. MY23 D350 HSE

That's why they give us downsizing options with new models.
