The Jeep story began 79 years ago. At around the time Enzo Ferrari and Alfa Romeo conclusively parted ways, the United States Department of War sought to commission the design of a rugged reconnaissance vehicle for duties in febrile Europe.

Out of more than 130, just two companies, Willys-Overland and Bantam, stepped up, and it was the latter’s BRC 40 that formed the basis of not only a bona fide military icon but also, with the advent of the CJ-1 just four years later, an enduring post-war civilian sales success.

The JL is the fourth generation of this remarkable machine since the ‘Wrangler’ name was first applied to the recipe in 1986, and it is the subject of this week’s road test. In the time it has taken the model to make it across the Atlantic and into British dealerships, more than 240,000 have already been sold in North America, making it the most popular Wrangler to date and something of a global commercial powerhouse for its Fiat Chrysler Automobiles parent company.

Early indications are that Jeep’s improvements to the cabin ambience and more frugal engine line-up are largely to thank for this, though there is one other factor that can’t be overlooked: brand.

To succeed, any new Wrangler needs to radiate its Rubicon Trail-conquering capabilities at a standstill, which is why Jeep has altered the model’s aesthetic only tentatively. And yet with the JL more than any previous generation, the real challenge has been not only to maintain and enhance this aura but also make the car a far more amenable daily companion.

Indeed, solid axles and a flip-down windscreen might please Wrangler aficionados, but for wider sales success in Europe, Jeep will need to have squared such serious attributes with hitherto absent road manners and an interior one could happily live with.

Time to find out whether it has succeeded.

The Jeep Wrangler range at a glance

Two engine choices are available to power the Wrangler: a 197bhp diesel and a 268bhp petrol. The two-door model will likely appeal to those after a more classic Wrangler look, while four-doors offer improved practicality and a longer wheelbase.

Three trim levels are offered in the UK: the entry-level Sahara; the more luxurious Overland; and Rubicon, the most off-road-focused variant. Various roof styles are available for open-air motoring, including a three-piece removable roof.
