WITH roots going back to the legendary Willys Jeep of World War II you would expect the US-based maker to adopt an "if it ain't broke don't fix it" approach when it comes to updating the legendary Jeep Wrangler.

Such is the case with what Jeep calls the "all-new, next-generation" 2018 model, first teaser pictures of which have just been released.

It looks little different to the outgoing version, or, in Jeep's words, the 2018 model "stays true to the original".

Details are scant ahead of its public unveiling at the Los Angeles Auto Show later this month but Jeep promises advanced fuel-efficient powertrains, more open-air options, improved aerodynamics and that it will be loaded with more safety features and advanced technology than ever before.

The all-new Wrangler's unique design includes an instantly recognizable keystone-shaped grille, iconic round headlamps and square tail lamps, a signature fold-down windscreen for off-road purists, more open-air freedom and dozens of different door, top and windscreen combinations.
