Jaguar XF vs Jaguar XJ

What's the difference?

If a Jaguar owner fell through a wormhole from 2003, the company they bought their car from would be   almost unrecognisable. Back then, it was a bewildering mess making an odd assortment of cars, yet to emerge into the light after Ford's confused and debilitating period of ownership. 

Why 2003? Fifteen years is a nice round number and pre-dates the arrival of the brand-saving XF.

Today, Jaguar has three SUVs, and the gorgeous F-Type, the XE, its second-generation XF and the big XJ. It has three SUVs (the F-Pace, E-Pace and I-Pace) because without them Jaguar would be a niche manufacturer before long, because big sedans, formerly the brand's trademark, are continuing their gentle decline. Oddly enough, one of the market segments contracting even faster than sedans is wagons. 

So what better time to launch into a draining pool from the three-metre board than now? Jaguar has bravely taken that risk and brought us the puzzlingly named XF Sportbrake.

As a child, my parents - who aren't car people - would see a Jaguar and point. It didn't matter if it was an XJ, Daimler Double Six or a Mark II, there was a great deal of mystique around these bastions of Britishness. It also didn't matter that these weren't necessarily good cars. The Seventies and Eighties saw the brand slide into a funk while being passed between owners like hot potatoes.

Somehow, the brand survived its brush with Ford's useless Premier Automotive Group strategy which only came good towards the end as Jaguar's management woke up and put in place a change in direction that produced the Ian Callum-designed XF. Riding high on that design, Jaguar then promptly introduced the very pretty Jaguar XJ.

It has been on sale for ages, but with the addition of a few bits and bobs to stay competitive, it's as compelling as ever. Most importantly, the performance-focused R has kept its unique supercharged V8.
