Jaguar has released two new 'performance-driven' option kits for the XJ - The Sport Pack and the Speed Pack.
Tick the Sport Pack box for your new XJ and you'll get a splitter on the front, an extended bootlid lip, gloss black mesh in the grille and red brake calipers peeping out from behind new 20-inch 'Venom' alloy wheels.
Inside are tweaks to the front (optional sports) and rear seats, and fillets of carbon fibre here and there.
The Sport Pack is available on all models except the supercharged car. On that, you can now get the Speed Pack, which takes all the cosmetic and aerodynamic additions of the Sport pack, but raises the electronically limited top speed from 155mph to 174mph.
Which we will admit is a little pointless unless you live near an autobahn, but it is useful ammo in the pub...
