My current DD is a 2011 Jag XF Supercharged (comes with 20" wheels) with the ECU tune package (~520-540hp), and this is my second XF.I just drove the TMS P85 with 19" wheels for about 45 minutes in mix of city, highway, good/bad road surfaces, etc.Here are my thoughts ,strictly as compared to my car.
1) It is uncanny how the TMS immediately felt so similar to the XFS on the road as far as ride quality, steering and handling in general.Driving over bad road surface, feels same as the XFS.
2) Seat, driving position, steering position is very good
3)For an ICE, the XF has same philosophy of less is more - as far as physical switches and controls.Much more low key and elegant compared to anything German
4)when quickly turning the wheel left-right-left-right in low speed, the car is not planted, feels like the tire sidewalls are too soft or suspension is loose and it sways a lot.
5) Test Car has 5000+ miles, and no rattles, creaks at all
6)Accelerating hard from any speed between 0-65mph, the P85 feels faster for sure. Stepping on it above about 70mph, I would say the XFS easily pulls away. This is of course the normal expected difference between the ICE and E-motor torque/power delivery curves
7)interior quality is a lot of hits and misses considering it's a $100K car,definitely lower quality overall then the XFS. Too much plastic (low grade hard plastic)all over the place. The tray between the front seats is the most ridiculous thing, and a major screw-up, which by itself brings the whole interior down- however should be an easy fix.
8) visibiliy out the back is worst than even the XF, but I did not feel any issues on the road. Would be nice to have parking sensors for such a large car - that's a no brainer.
9) car is of course very quite at low speeds. At about70mph and above, total cabin noise is same as the XFS
10) switches on the steering wheel feel cheap and flimsy
11) Until today, I haven't seen an MS around here. Today suddenly I saw 2 on the road....
12)I lease my cars (36-39 month leases, 15Kmi/year)The XF normal maintenance costs are definitly lower than the S up to at least 4 years. Incidentally,the cost for the TMS is close to $1000/year and not the claimed $600. (adding the rumored $30/mo for 3G connectivity).
13)Came away from the test drive impressed,but not blown away. Considering the rave reviews, and how so many people are blown away by the TMS, I have a new appreciation for the XFS, which costs 30% less.
14) Note that I am not discussing the range issue at all in this report.
