Jeep Wrangler vs BMW Z4

What's the difference?

The Overland is (surprisingly) not atrocious on-road and (not surprisingly) very capable off-road. It costs a lot but, geez, it's a barrel of laughs.

If your heart is set on a four-door mid-size 4WD that's a whole lot of fun to drive, but rather impractical for daily life, then it’s difficult to over-look the Overland.

If you’re really gung-ho about hard-core off-roading – rock-crawling etc – then perhaps you should focus on the Rubicon, but for everything else the Overland, even on standard tyres, is more than capable.

The Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

The Wrangler's appearance has been tweaked throughout the years without ever sacrificing any of the ol’ Wrangler spirit.

It has stuck to its traditional roots and, as such, retains its old-school chunkiness, which is good, but the Overland is less of a hardcore-looking 4WD and more of a lifestyle-suited off-roader than its Rubicon stablemate. 

Though the Overland version has a certain blocky appeal, I reckon the Rubicon is better for having fully embraced the all-out off-road look and feel, tyres and all. 

The Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

What can you say about a vehicle that has a “wash-out interior with drain plugs” listed in its specs?

This is a purpose-built off-roader and the Overland’s five-seat cabin is a basic but functional space, in which it’s easy to immediately feel comfortable. 

All dials, knobs and switches are easy to locate and chunky enough to operate while skipping over corrugations or climbing up steep rock steps.

There's leather everywhere – seats, steering wheel, shifter knob – but durable outdoors-tough surfaces also abound.

What always strikes me about the Wrangler interior is the fact that it’s abundantly clear Jeep designers regularly experience – or at least are familiar with – the type of life that Wranglers are aimed at: fun, dirty, rough-and-tumble adventures in the great outdoors.

There isn’t a lot of storage space inside but there are a few small, deep, and textured receptacles – ideal for keeping your bits and pieces in the same spot while you bounce around off-road – as well as grab handles, including a big sturdy one in front of the front-seat passenger. 

There are also tensioned net pockets on the doors so you can throw stuff in there, but beyond those there aren't a lot of storage options.

There are air vents, two USB-C ports, and a 230V inverter in the centre console.

Rear cargo space is listed at 898 litres; with the rear seat stowed away, there is a claimed 2050 litres of room.

The Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

The Z4 isn’t cheap, but it plays in a field of expensive Deutsche drop-tops. Our car was the mid-spec 30i which comes in at an MSRP of $104,900 (before on-road costs).

For that you’ll get a more highly tuned version of the base 20i’s four-cylinder turbocharged engine, producing 190kW/400Nm, 19-inch alloy wheels, M Sport brakes, Adaptive M suspension, and adaptive LED headlights.

That’s on top of the already impressively-specified 20i’s kit which includes dual 10.25-inch screens – one for the multimedia functions, the other as a digital dashboard, a head-up display, full Vernasca leather interior trim, auto-dimming rearview mirror, power adjustable and heated front seats with memory function, dual-zone climate control, 10-speaker 205W stereo, a Qi wireless charging pad, and adaptive cruise control as part of a marginally upgraded safety package (more on that in the safety section).

It’s a pretty plush set of equipment, although a challenging value proposition as the almost-as-well-equipped 20i starts from $84,900, a full $20k cheaper.

Rivals for this 30i model? You’ve got the soon-to-be-discontinued Mercedes-Benz SLC300 ($102,500), all-wheel drive Audi TT S quattro ($105,661), and, at a stretch, the entry-level Porsche Boxster ($122,960).

Of course, being a premium European car, there is an extensive options list. Our car was fitted with the excellent and probably-worth-the-money M Sport differential ($2400), as well as the rudely priced M seat belts (literally just the M pattern embroidered in - $560!) and interior ambient lighting package (lovely, perhaps not worth $550).

The Z4 is only offered in five colours, three of which – including our car’s Black Sapphire – come at a cost of $2000. The red interior, surprisingly, is a no-cost option.

If you’re keeping track that brings the car you’re looking at here to $110,410. Not cheap, and it doesn’t have six-cylinders - but given its other attributes explored later in this review, the fact that it still manages to undercut an entry-level Boxster is actually reasonable.

This Jeep has a 3.6-litre 'Pentastar' V6 engine – producing 209kW at 6400rpm and 347Nm at 4100rpm – and an eight-speed automatic transmission.

It's an effective engine-and-auto pairing for driving on sealed surfaces and well suited to high- and low-range 4WDing.

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

Official fuel consumption is listed as 9.7L/100km on a combined cycle. 

Actual fuel consumption on this test, from pump to pump, was 13.6L/100km, largely attributable to the fact I did a lot of low-range four-wheel driving on this test, as always. 

The Wrangler Overland Unlimited has an 81-litre tank so, going by that fuel figure above, you could reasonably expect a driving range of about 595km from a full tank.

Note: Drop 30km to 50km from your total calculated fuel-range figure for a better idea of your vehicle’s safe touring range – so that figure above would be 565km.

Also, remember that numerous other factors affect your fuel consumption and so impact your touring range, including how much extra weight you have onboard (passengers, camping gear etc), whether your vehicle is fitted with any aftermarket equipment (bullbar, spare-wheel carrier, etc), whether you are towing (a camper-trailer, caravan, or boat etc), your vehicle's tyre pressures and the conditions.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

The Wrangler Overland is a fun, go-kart style drive and yields a real driver-direct experience you get from few other contemporary vehicles on the blacktop and the dirt.

But while it’s nowhere near as atrocious as you might expect on sealed surfaces its planted, squared-off stance gives it a definite composure on bitumen. It’s certainly no sports car in terms of ride and handling.

It’s quite soft on-road, soaking up most imperfections with ease, but it also takes quite a lot of effort and concentration to keep this Jeep in line on the open road because it tends to float around on the blacktop if not constantly reined in. 

Also, its steering has a lightness about it that can sometimes be a bit disconcerting. 

The V6 is a gutsy unit, capable of punching the Overland along at a fair clip, all while the eight-speed auto handles clever and nicely controlled shifts.

Because it’s so blocky, straight up and down, with big wing mirrors and the like, the Overland is rather noisy on sealed surfaces.

But it remains one of the few modern vehicles that deserves to be driven with the windows down, because it offers that kind of visceral driving experience – as the LC70 Series, or Suzuki Jimny do.

So, how does the Overland perform off-road? Bloody glad you asked.

Spoiler alert: The Overland is not as good an off-roader as the Rubicon because it does not have that variant’s BFGoodrich Mud-Terrain tyres, 'Rock-Trac' active on-demand 4x4 system (with 4:1 transfer case*, and 77.2:1 crawl ratio), front and rear locking differentials, or the Rubicon’s very handy electronic front sway bar disconnect. (* The Overland has 2.72:1.)

But, having said that, the Overland is still an extremely capable off-roader.

To be honest, I wasn't expecting any strife because it retains all the traditional goodness of the Wrangler with very few compromises. It’s a genuine 4WD with a dual-range transfer case, a ladder chassis, solid axles and well-proven 4WD heritage.

In terms of size, the Overland is 4882mm long (with a 3008mm wheelbase), 1894mm wide, 1838mm high. It has a listed kerb weight of 1900kg.

Steering has a nice weight to it at lower speeds, giving the driver a great sense of sustained control through even the most severe obstacles, but the Overland’s turning circle is a listed 12.44m, so this off-roader can sometimes feel like a mini-bus to steer through tight turns.

However, this is a purpose-built off-roader with a wide wheel track and low centre of gravity, so it feels planted no matter how rough and bumpy the terrain gets.

On the gravel track to our off-road testing site, there are numerous steering-wheel-jolting corrugations but overall the Overland – with a coil spring at each corner – soaked them up.

Our 4WD loop included the aforementioned gravel tracks, light to medium corrugations, undulating mud tracks and mud holes, and some very challenging low-range 4WD sections (in particular, a steep rocky hill), and a few other set-pieces to see if the Overland was able to do everything safely and comfortably. 

As a true 4WD worth its weight in gold, the Wrangler is immediately more at home taking on low-speed 4WDing than it is negotiating suburban traffic.

Again, the V6 engine comes into its own, delivering smooth, even torque when needed, but not ever over-working to achieve that.

Considered driving is necessary as is slow and steady throttle, but that's easily achieved in the Wrangler as its go pedal is none too sensitive to a bouncing boot.

It’s refreshing to note that switching to 4WD High or 4WD Low range is still done via a stubby stick to the left of the auto shifter, rather than the push of a button, or the turn of a dial. 

Low-range gearing is very good and the Overland has a well-calibrated off-road traction control that seamlessly launches into action when required, and wasted wheelspin is kept to an absolute minimum.

This Wrangler has 242mm ground clearance and a standard wading depth of 760mm, and was never troubled on climbing steep rock steps, traversing deep ruts or punching through mudholes.

It’s supremely sure-footed during low-range work but visibility can be an issue: over-bonnet visibility has improved slightly over previous generations but the driver’s view to the front and side is still a bit squeezed, making it at times difficult to visually pick correct wheel-placement, especially when driving steep terrain at sharp angles.

It can go hardcore, no worries, but it simply requires a bit more thought and you know what? That’s fine with me because it makes the off-roading experience an even more engaging one. 

The Overland has approach, departure and breakover angles of 35.8, 31.2 and 20.4 degrees, respectively.

With live axles front and rear, the Overland has plenty of wheel travel to keep moving and under control through truly off-grid country.

The only real compromises in the Overland’s 4x4 set-up are its standard Bridgestone Dueler (255/70R18) highway tyres and, even on those, the Overland walked up and over our toughest off-road challenges.

Though the Overland is not historically regarded as a towing platform, it’s handy for you to know that it has listed towing capacities of 750kg (unbraked trailer) and 2495kg (braked).

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

Convertibles and safety don’t often fall in the same sentence, unless its one where a concerned relative is trying to convince you not to buy one.

In any case, the Z4 benefits from four airbags (dual front and dual side), as well as the expected electronic stability controls. That optional M Sport differential will have the added bonus of preventing any unexpected slip and slide at the rear.

On the active side the Z4 gets ‘Driving Assistant’ which includes forward collision warning (FCW), lane departure warning (LDW), rear cross traffic alert (RCTA), and rear collision warning. The 30i grade also gets 'active cruise control with stop & go' which allows for full auto emergency braking (AEB) with pedestrian and cyclist detection. Not on the spec sheet, but apparently present in the car I drove was some form of traffic sign recognition (TSR) and lane keep assist (LKAS).

A nice high-res reversing camera displayed on the massive touchscreen is a welcome standard addition.

Considering the meagre safety specification of most convertible cars, the Z4 30i shines with a half-way decent active safety suite. But you can forget ISOFIX child-seat anchor points. There aren't any. 

The Overland Unlimited is covered by a five-year/unlimited km warranty.

Servicing is set at 12 month or 12,000km intervals at a total cost of $1995 over five years, with servicing capped at a maximum $399 per appointment.

Lifetime roadside assist is available to Overland owners when they service through Jeep.

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.
