JAGUAR’S current-generation, X350 XJ is a glorious failure. Hampered by yesterday’s styling, it is clear that potential buyers have not appreciated the fact that this full-sized sedan is still very much tomorrow’s car underneath, thanks to technologies like advanced aluminium construction and computer controlled air suspension. So Jaguar has tried to make it look a little more modern, reinstated its smooth and willing 3.5-litre V8 powerplant as the base petrol engine, and included more standard features. But while we don’t think the styling is wholly successful, the base XJ8 – rich in feel, rewarding to drive and oozing in personality – is an unmitigated success as far as meeting the luxury car criteria is concerned.
