Was the XKRS available in 2010 for the 5.0 engine? What about the Speed Pack, Black Pack, or Signature Edition?
I believe the Speed Pack and Black Pack were only introduced for the 2011 model year, but I'm not sure. No idea about the Signature Edition.
Would love to confirm
Thank you.

 

Not sure, but the dynamic pack is the biggy. My 2011 175 was the base with a speed body kit in black (nothing special, but advertised as a special edition). Sold it and bought a new 2013 with dynamic pack, performance exhaust and polished vulcan wheels in 2013. Sold it in 2015. I missed them so much I've been looking for a replacement, convertible, loaded ever since at a good price and found one. I'm picking up a 2014 XKR today from the car carrier. It is loaded, dynamic pack, performance pack, black pack, performance exhaust, heated wind screen and ultra low mileage. Even comes with wind screen and CPO until May 2020.

 

The XKR-S 5.0 is a 2012 car; there was a 4.2 R-S in 2008. The 75 (not the 175), released in 2010 but a 2011 MY car, was the first 5.0 (as far as I can determine) that had the suspension mods that became the Dynamic Pack and the x-pipe centre section that became the Performance Active Exhaust. The 2011 brochure mentions the "new Black Pack and Speed Pack", so those were introduced in the 2011 MY; this is confirmed by the 2011 press release. The Dynamic Pack & PAE are not mentioned.

Because the 2011 MY cars were sold from March 2010 (based on the owner's guides on Jaguar's website), I think you could have bought a Black Pack or Speed Pack car in 2010, but not before March.
