New electronic technologies meet traditional mechanical strengths to deliver peerless off-road prowess with added everyday appeal
18 May 2018

What is it?

The descendant of the original US Army workhorse has been completely redesigned.

Already on sale in its home market, the JL-generation Jeep Wrangler will reach the UK in November. Once again, it's available in two-door or four-door form, and we drove the latter in range-topping Rubicon guise on and off-road.

The styling is best described as evolutionary; you mess with the Wrangler’s looks at your peril, so LEDs are incorporated into the signature round headlamps and the seven-slot grille bends over halfway up to keep the air attached as it flows over. This design tweak is one of several features that deliver a fuel-economy-boosting 9% reduction in aerodynamic drag over the outgoing, 12-year-old JK-generation model.

The contemporary approach to a traditional formula extends into the vehicle architecture. A ladder-frame chassis and Dana solid axles are retained but Jeep has used high-strength steel to take around 45kg out of the frame. It’s part of an overall 90kg drop in weight, despite the new car's slightly increased dimensions and additional equipment.

An all-new electrical architecture brings the Wrangler bang-up-to-date, not only in features like the Uconnect infotainment system and USB-C port, but also through driver assistance technology such as a reversing camera and blindspot monitoring. In a neat touch, four auxiliary switches on the centre stack can be configured via the 8.4in touchscreen to run aftermarket off-road accessories such as floodlights and foglights.

What's it like?

Two petrol engine options are currently available in North America, the 3.6-litre V6 driven here and a turbocharged 2.0-litre four-cylinder with Jeep's eTorque 48V mild hybrid system. The latter shares a block with the Alfa Romeo engine of the same capacity but has a dual overhead camshaft head rather than the MultiAir one. UK buyers will have the choice of the 2.0-litre petrol or a 2.2-litre diesel.

The V6 is fine when crawling over off-road trails, but peak torque doesn’t arrive until 4800rpm, and on winding roads or hills you have to row the gears of the new-but-notchy 6-speed manual gearbox to maintain momentum. All UK-bound Wranglers will get an eight-speed automatic gearbox, however, and we’d expect the combination of the turbocharger and eTorque electric motor to take care of the missing low-end oomph (and use less fuel in the process).

Road manners are much improved over the JK. The new electrohydraulic power steering is light but has a more precise, car-like feel, while the Rubicon's all-terrain tyres are impressively quiet and there’s far less body roll than you might expect. The front anti-roll bar can be electronically disengaged off-road. We’ll need to see how the ride comfort shapes up on UK roads, but the initial signs are good.

On a challenging trail in a Rubicon equipped with the eight-speed automatic ’box, the ride quality and sheer effortlessness exposed car-like SUVs as the pretenders they really are. The JL Wrangler’s performance is further extended by higher approach, departure and breakover angles than the JK and by the introduction of a hill descent control that uses the shifter’s manual shift function to control the speed of descent.

Meanwhile, the electric portion of the steering’s assistance and a tighter turning circle make it easier than ever to plot your course – and to park when you reach the top of the mountain.

Should I buy one?

The on-road improvements and additional equipment, together with ergonomic upgrades to the soft-top and passenger accommodation, make this the most everyday-usable Wrangler yet.

Jeep appears to have addressed some of the car's shortcomings without compromising its off-road DNA, and that’s important because, unlike most SUVs, around 90% of Wrangler owners take their cars off-road at least once a year. If you plan to be among them, the Jeep has few rivals to its capability.

Reliability might be a concern for anyone using the new electronic systems in extreme conditions, however. It’s too early to know whether those concerns might be justified, but Jeep's engineers have gone out of their way to keep it all functional, no matter what. Anything electronic within 76cm (30in) of the ground is fully waterproof and the Wrangler had to pass a 16-hour misting test that simulated being left out in a storm with the roof and doors off. Extreme testing for an extremely good extreme vehicle.

...........on the current model.

I dislike the fact that JEEP UK have decided that we are not to be trusted with the V6 engine, which coincidentally would be my choice with the auto box.No way would I take a diesel version or a Hybrid to go fording rivers with....despite the 30 inch assurance.

I am not sure about the LWB version either....for me a SWB V6Auto would be good....amazingly I am quite taken with the bright red too.

Is it too tedious to lament once more the direction JLR are taking with the new Defender?

The new JL Wrangler is a highly credible and smartly conceived successor, and much more affordable than the new G wagen (albeit prices have increased sharply over the old model).

US punters have been taken aback at being asked $50k for a fairly standard model... but its broader capabilities seem to justify the price.

As Land Rover have abandoned this sector - the true, dedicated off-roader - I’m just pleased that Jeep sees the Wrangler as an essential part of its heritage. Of course in the US this is a big seller and profitable. Here in the UK the market for Wranglers has always been small but dedicated, largely because of its niche appeal to those looking for a fun, truly off-road capable vehicle that is not exorbitantly priced. I owned a TJ for nearly 4 years and look back on it with great fondness. Those who’ve never driven one, however, need to accept that Wranglers are not car-like and compromises must be accepted. They are not the same as the vast herds of road-biased SUVs now swarming on our roads.

No doubt much of what I’ve said applies to the Land Rover Defender, but I long ago gave up hoping that a truly rugged and affordable successor will emerge from McGovern’s Premium Emporium. Perhaps the Projekt Grenadier venture headed by the boss of INEOS (Jim Ratcliffe is now the richest person in the UK) will produce something closer to a modern Defender? In the meantime, I’m looking forward to seeing the Wrangler JL when it arrives here.

I've had three Defenders and a Range Rover in the past, but my next car will be a Jeep Wrangler.  I just can't wait though!  It's going to be in the UK later this year, and I hope to be one of the first owners.  The Defender has taken wayyyyyyyyyyyy too long, and it will be overpriced.  But as I can't even see a pic of it then I've given up completely.  I've already set aside cash for the Mopar bits I want on my Wrangler.  Land Rover - you know what you can go and do.

Good man! Are you going for 2” lift kit, Mopar steel bumper, 35” tyres etc? Or more extreme? Or more road biased? Such an easy and fun vehicle to customise, and if the dealers are able to fit these goodies from new you may even be covered by the factory warranty. My pick would be the Rubicon, and that’s the model I’m most looking forward to seeing.

I'm going for the 37"s and 2" lift.  I'm really undecided on colour, though.  The Rubicon is thought to be only £2-3k more, so might as well.

i have had a 2 door JK for just over 4 years now, and its great. I was really hoping we would be offered a manual with the JL as we are told they want to sell more, but if they are auto only i dont see any point in changing. I wouldnt be keen on a 2.0 in exchange for the V6 either, its a poor show to let us have so much less choice than the US market

the XC90, Discovery Sport or an X5 rivals? Non of them are serious off roaders, and that includes the Discovery.
