Jaguar XJ Review: Long-term Jaguar XJ departs

Our long term Jaguar XJ goes home Doesn’t time fly when you’re having fun? It seems only five minutes since we wrote that our long-term Jaguar XJ would be here until ‘… the leaves are coming back on the trees in the Spring’.

McLaren 50 12C & 12C Spider celebrate McLaren’s 50th anniversary

McLaren say they will be building a maximum of 50 each of the 50 12C Coupe and 12C Spider to mark the occasion, both of which get special features provided by McLaren Special Operations – the same McLaren division that created the 12C High Sport. That means a new front bumper which has been optimised by Computational Fluid Dynamics (CFD) for more downforce, extra carbon fibre and kevlar exterior bits, ceramic brakes, 19″ front and 20″ rear alloys, full leather, extra carbon fibre in the cabin, a heritage badge and a numbered plaque. There will be the option of three colours for the 50th anniversary 12Cs - Carbon Black, Supernova Silver and, of course, McLaren Orange – and each car will get its own silver car cover, a limited edition key in a carbon fibre box and a signed art print (sadly, there’s no sign of a tool chest or Tag Heuer watch).
