When the first of the previous-generation Jeep Grand Cherokees arrived at our office for testing in August 2005, one tester wrote in his notes: “I don’t know what they were thinking of.” Five months later, when we named and shamed the worst car we’d driven all year, the Jeep got it without a single dissenting voice.

It was crude, cramped, overpriced and over here. Were its mediocrity not so prejudicial to its creator’s health, it would have been laughable.

But perhaps in time we’ll regard it as its equivalent of the Mk4 Ford Escort, a car so bad that it actually became a force for good, stinging the firm out of its complacency and into action. Ford’s next two cars were the Mondeo and Focus and it has never looked back.

We usually save this bit for the verdict, but there is something you should know now: the current Jeep Grand Cherokee is almost indescribably better than the model it replaced.

A mid-2013 update improved the new Grand Cherokee even further, adding an eight-speed automatic transmission and cosmetic improvements including changes to the lights, grille and rear tailgate.

The question, though, is whether it's good enough to compete with the likes of the Land Rover Discovery. Let's find out.
