2022 BMW M4 vs 2018 Foton Tunland

What's the difference?

We cannot think of a faster or more invigorating four-seater luxury convertible for the money than the new M4 Competition.

Finally, after years of devastatingly fast droptops with remote steering and an unforgiving ride, the G83 generation discovers refinement and sophistication to go with its supersonic speed.

There’s terrific talent on tap here that no rival can even come close to right now. BMW is on a roll and this is the first M4 convertible that can sit proudly alongside the best of its classic M3 ancestors.

The 2018 Tunland is a big improvement on any Chinese ute we’ve driven. Foton has done a commendable job in selecting known brand components and bringing them together into one cohesive package that delivers robust performance. Although it doesn’t quite equal the sum of its parts (mostly owing to poor safety features and some technical quirks), it’s still a lot of 4x4 dual cab ute for not a lot of money, and it's worthy of a test drive.

Hallelujah! The unloved folding hardtop is history and fabric is back in fashion in a BMW 3/4 Series-based convertible for the first time since the demise of the E46 convertible in 2006.

It improves the proportions and aesthetics out of sight while remaining superbly insulated. It’s also 40 per cent lighter to boot while liberating 80 litres of extra luggage space.

The roof requires just 18 seconds to drop away or erect again, and can be done so at speeds of up to 50km/h. And it looks great, with a taut fit that suits the BMW’s lithe lines to a tee. With all four windows dropped, it also does a fab impression of an American-style pillarless hardtop.

Roof up or down, the M4’s muscular styling has a tense sparseness to it that means business, reinforced by that oversized, M-specific kidney grille treatment that, admittedly, isn’t as divisive in real life. The smiley LED light wave out back also brings a friendlier tone, harmonising handsomely with the rest of the car.

This is probably the best-looking BMW convertible since the beautiful E46 era.

This is a big ute with an imposing presence, much like the Ford Ranger with which it shares similar dimensions (if not looks). Compared to the Ranger Wildtrak, the Tunland is 115mm shorter in wheelbase and 45mm shorter in overall length, but 20mm wider and 22mm taller. Ground clearance of 210mm is 27mm less and its kerb weight undercuts the Wildtrak by 250kg.

The Tunland uses traditional body-on-frame construction with a steel ladder-frame chassis, coil-spring twin-wishbone front suspension, leaf-spring live rear axle, four-wheel ventilated disc brakes and hydraulic power-assisted rack and pinion steering. 

Chrome body highlights include the grille, driving lights, side mirrors, door handle inserts and body badges. The dashboard and interior trim feature strongly textured grey surfaces with a tasteful mix of piano black, chrome, satin chrome and carbon fibre-look highlights. 

There’s good comfort for driver and front passenger, with a height-adjustable steering wheel and multi-adjustable driver’s seat with adequate under-thigh support that doesn’t feel too short like a Triton. The driving position is a big improvement on other Chinese utes we’ve tested, and is on par with many of the major players. The rear bench seat’s low cushion height results in raised upper thigh angles and knees, but also aids in providing unusually generous headroom, even for tall adults sitting in the higher centre position. 

The M4 Convertible is not a paragon of space efficiency, given its footprint.

At nearly 4.8 metres long and 1.9m wide, the M4 Convertible casts a sizeable shadow on the road, which only really pays dividends for front-seat occupants inside.

Ours was fitted with a very handsome pair of $7500, two-tone M Carbon bucket seats up front, a sort of futuristic tombstone design with a fixed headrest that looks like they were created by and for Stormtroopers; they do provide all the electronic adjustability one would need in terms of fore/aft, up/down and lumbar support movement.

But, unless you really need their g-force-bracing support and love their outrageous appearance, they are monumentally obstructive to effortless entry/egress and overall hip comfort if you don’t possess a gymnast’s physique. In fact, at times, they can feel downright torturous, especially in the gusset area due to the pointless (ironically) hard central bulge bit. The standard front seat set-up is perfectly fine, offering all the comfort and support expected in a luxury convertible, with the added bonus of headrest adjustability.

As with all G20/G80 generation 3/4 Series, the M4’s interior is a welcome return to form for BMW, from the excellent driving position and superb build quality, to thoughtful switchgear placement, brilliant ventilation and ample storage. And iDrive is probably the best and most intuitive multimedia system out there, too, needing no special skill or distraction once mastered.

A quick note about the instrumentation. The 4 Series design digital readouts are prettier than the standard 3 Series' ugly standard screen that looks ex-Honda Civic. This one offers alternative views and is easy to read at a glance. But it still makes us pine for good old analogue dials. Remember when BMWs were the world leaders in dial design?

Some familiarisation is also required to figure out the M part of the M4, including the various driving and performance modes; they’re divided into Road, Sport and Track settings. Yet, thankfully, they’re all far simpler to get your head round than before, which required too much fiddly concentration, since – once quickly learnt – everything is possible with eyes-on-the-road promptness. A new M Mode button offers pre-determined shortcuts to whichever drive combinations are desired.

The roof is well insulated, meaning that previous-gen folding hardtop-owning prospective buyers shouldn’t be too sad about the fabric above their heads. On the go, front occupants can enjoy a variety of configurations, starting with snug coupe-style cosiness and security, moving to cool pillarless hardtop-style windows-only down cruising, to the full top-down convertible glory. The latter also brings minimal buffeting at speed unless you’re stuck out in the back. Roof-up vision isn't brilliant, though.

Strangely, with the M Carbon bucket seat options ticked, it’s actually easier for some people to get into the back than the front. Pulling a strap sees the front bucket seats (slowly) whir as far forward as possible to allow sufficient room for people to clamber onto the rear seats.

Once sat, it’s clear that longer-legged people will struggle. Knee room is OK (especially if the front occupants are feeling sympathetic by moving their seats forward), there’s surprisingly adequate head room for your 178cm tester when slightly slouched, big feet can be tucked beneath the front seats and scalps never have to touch the rear glass thankfully.

And at least BMW has tried to make life back there comfier for smaller people, due to rear-facing air vents with climate and directional control, two USB-C ports, a pair of cupholders, a centre armrest and some handy storage. The materials are of a high quality construction, too.

However, the fixed back rest is far too upright, the knees-up posture quickly gets tiresome, the cushion is firm and you’re sat on a slight angle pointing outwards. Claustrophobics won't be too happy either. Annoyingly there aren’t side window buttons either, meaning only the driver can lower or raise them. The two-seater back seat is best saved for short trips or kids.

Happily, once the roof is dropped, the hemmed-in feel vanishes, there’s not too much wind intrusion or buffeting with the side windows up and there’s a sense of shared freedom that only a four-seater convertible can bring. Going the full drop-top experience will ruffle more than hairdos at freeway speeds, though. An optional wind deflector can fix that issue for front-seat occupants, but it goes over the back seats, turning the M4 into a two-seater ragtop.

Further back, the 300-litre boot isn’t accessible from the cabin, meaning you can’t put much inside at all. BMW fits a hinged flap that needs to be down for the roof to work since it cordons off the roof storage part of the boot when folded in; when lifted, there’s a useful amount of space for luggage, and it’s a handy rectangular shape instead of an L-shaped slot, but obviously at the cost of convertible driving. You can’t have both.

Note that, compared to the previous folding-hardtop M4, this boot is some 80L larger. 

Figures used here are provided by Foton Motor Australia Ltd and differ slightly from those shown in sales brochures. With a claimed kerb weight of 2000kg and 2925kg GVM, the Tunland is rated to carry a decent payload of up to 925kg.

It’s also rated to tow up to 3000kg of braked trailer, and with its 5925kg GCM, can tow that weight without having to reduce its peak payload, which gets a big tick from us.

Load tub dimensions of 1520mm length, 1580mm width and 440mm height provide more than a cubic metre of enclosed load volume. There’s also 1140mm between the wheel arches (not wide enough for a standard Aussie pallet) plus four sturdy tie-down points for securing loads.

Cabin storage options includes a bottle holder and pocket in each front door, a shallow tray inset in the centre dash pad, an overhead sunglasses holder and single glovebox. The centre console has an open cubby up front, two cup holders in the centre and a small lidded box at the back which doubles as a well-placed armrest.

Rear doors also have bottle holders and storage pockets, plus there are flexible storage pockets on the rear of each front seat and a fold out dual cup holder on the rear of the centre console. The rear bench seat’s base cushion also swings up through 90 degrees to reveal two hidden storage areas beneath for the wheel-changing tools and other smallish items.

The Foton Tunland is made in two model grades – the H-series (High End) and S-series (Super Value). The S-series (which is not sold here) is a low-cost, steel-wheeled version with components sourced from Chinese suppliers. The H-series is the premium model sold in Australia, so don’t let the red S badge on the tailgate confuse you as it did us at first. The S badge stands for Sport (not Super Value) and is only affixed to H-series vehicles.

The Tunland range comprises 4x2 manual ($26,990), 4x4 manual ($29,990), 4x4 auto ($33,990) and, thanks to its leather seats, 4x4 auto Luxury ($35,490). The 4x4 manual Luxury has recently had a big price reduction from $30,990 to $27,990, reflecting Australia’s growing preference for automatic transmissions.

Our test vehicle is the 4x4 auto, which for a snip under $34,000, brings numerous useful and desirable features including 17-inch alloys and beefy 265/65R17 road-biased tyres with matching spare, power/heated door mirrors, daytime running lights, side steps, auto headlights, rear-view camera and rear parking sensors, leather-trimmed steering wheel with audio/cruise control buttons, power windows, four-speaker sound system with multiple connectivity, eight-way (manual) adjustable driver’s seat and more. Plus there’s an extensive range of accessories.

Here is a summary of Australian-market outputs and prices for the M3 and M4 convertible autos, with the prices in brackets being approximate inflation-adjusted figures for today.

1999 E36: 236kW/350Nm 3.2L in-line six-cylinder engine (I6), $152,000 ($266,000 in 2022); 2003 E46: 252kW/365Nm 3.2L I6, $158,000 ($240,000); 2008 E93: 309kW/400Nm 4.0L V8, $183,442 ($240,000); 2014 F83: 317kW/550Nm 3.0L twin-turbo I6, $178,430 ($202,000).  

In 2022, the G83 M4 Competition lives up to its name in more ways than one, with a 2993cc 3.0-litre double overhead cam direct-injection twin-turbo I6 known as the S58 series, which is itself derived from BMW’s B58 modular family of engines. Its 375kW is delivered at a lofty 6250rpm, while there’s a 650Nm plateau of torque between 2750rpm and 5500rpm.

A kerb weight of 1920kg means the M4’s power to weight ratio is an impressive 195.3kW/tonne, helping its published 0-100km/h time of 3.7s. For a few grand extra, the company will up the top speed by 30km/h, to 280km/h.

BMW says the engine includes cooling and oil supply systems designed for extreme lateral forces at high speeds, while the exhaust uses electrically controlled flaps for a more raucous noise.

Power is channelled to all four wheels continuously via an eight-speed M Steptronic transmission with a trio of shift programs. The AWD system features an active differential to better transmit torque to all four wheels, while drivers can choose one of three, progressively more rear-wheel drive (RWD) biased modes: 4WD, 4WD Sport and 2WD – the latter being a pure RWD set-up.

Other related changes the M4 boasts over regular 4 Series models include special stability and traction control tuning, a double-joint spring strut front axle with unique axle geometry and variable-ratio steering, a five-link rear axle featuring its own kinematics and elastokinematics, M-specific adaptive dampers, a configurable braking set-up according to feel and response, and forged M light-alloy 19-inch alloys up front and 20-inch items out back.

Choosing the AWD-only convertible over the equivalent AWD coupe adds 145kg (and 195kg compared to the RWD coupe), though this is partly offset in two ways over the preceding, folding-hardtop M4 Convertible: firstly, using the soft top drops weight by 80kg; and secondly, while the AWD system does add 50kg, it’s at a lower centre of gravity, thus naturally improving vehicle dynamics.

Which are electrifying, by the way.

One of the Tunland’s strong points is its Euro 5-compliant 2.8-litre four-cylinder Cummins ISF turbo-diesel, which Foton claims is the first ute in the world to be powered by this engine. It delivers 130kW at 3600rpm and 365Nm across a pretty flexible 1600-3200rpm torque band.

The smooth-shifting six-speed German automatic behind it is from another premium OEM supplier in Friedrichshafen AG, better known as ZF. Its gearing and shift protocols are well matched to the engine’s characteristics, offering a choice of full-auto mode or sequential manual shifting. Console buttons also provide a choice of Economy, Sport or Snow driving modes.

American OEM giant Borg Warner supplies the part-time, dual-range 4x4 transfer case, while another  major US supplier - Dana - has its stamp on the front drive-shafts and live rear axle assembly, featuring a 3.9:1 final drive and limited-slip differential. There’s no locking rear diff option available.

We managed 12.1 litres per 100km in a mixture of urban, freeway and rural-road driving, including plenty of performance testing. This is a two-tonne M4 convertible capable of supercar speeds, after all. In that context, the economy is more than acceptable. No doubt the stop/start engine function (at idle) helps here.

For the record, the official combined-average claim for this Euro 6-rated BMW is 10.4L/100km, for a carbon dioxide emissions average of 237 grams/km. Thanks to a fuel tank that holds 59 litres of 98 RON premium unleaded petrol, it can manage an average of almost 570km between refills.

Foton’s official combined figure is 8.7L/100km but our ‘real world’ road test figures based on fuel bowser and trip meter readings came in at 12.2 (after 503km) and 12.1 (after 297km). Based on those figures, you could expect a driving range of around 620km from its 76-litre tank. However, after only 500km the fuel gauge needle was nudging the red zone and the low-fuel warning light came on, so we weren’t game to find out if there was another 100km-plus of driving available from the theoretical fuel remaining. 

Marvellously.

Earlier, we said that the previous M4 (and some earlier M3 generations) never hit the dizzy heights the best like the E46 managed.

The reason why is bandwidth. Not WiFi bandwidth, but rather the newfound breadth of capability that the G83 model has acquired.

Yes, while even the slowest examples of previous M3s and M4s remained thrilling, with blisteringly potent acceleration accompanied by a soaring exhaust soundtrack, the post-E46 models seemed to become almost too obsessed with the pursuit of performance. Thunderous V8s and twin-turbo V6s are all good and well, especially when they provide explosive responses, but there’s more to sports cars than sheer bloody-minded speed.

More specifically, though the handling and roadholding were outstanding, the previous M4’s steering didn’t feel as connected or one with the driver, instead seeming a little remote and detached. Conversely, even with adaptive dampers on offer, the suspension (on Australian roads) lacked sufficient isolation from bumps and thumps, and so was never settled or calm. It was all too nervous and edgy, like a drug-addled athlete who’s indulged in too much partying.

Thankfully, the curse is broken with the latest iteration, even in the heaviest and slowest version like our M4 Convertible as tested, pushing out boundaries to thrilling effect once more.

With the newly-simplified and logically presented M performance modes only a push of a button away, the driver now no-longer has to concentrate on what setting they’re in, and instead just immerse themselves in the experience of accelerating, steering, cornering, braking and controlling this incredible sports convertible.

Tremendously strong in regular Road mode, the M4’s performance certainly lives up to the legend, stepping up into the supercar realm when Sport or Track are chosen, hunkering down as it thrusts towards the horizon with relentless speed and determination, accompanied by the gorgeous twin-turbo six’s revs as they soar towards the red line. The ultra-alert eight-speed auto’s operation is equally seamless, displaying uncanny intuition in its selection of the right ratio at exactly the right time.

These are all incremental improvements over what has come before. But what’s really changed is how rock-solid the BMW feels as it belts along at speed, magnetised to the motorway regardless of weather, its new AWD engineering keeping everything steady and planted. No more tetchiness to unnerve the driver.

Which makes the feel and fluency of the chassis even more remarkable, given that now all four wheels are driven. The very opposite of leaden or inert, the superbly weighted steering is instead light and alive in your palms, as you carve through corners with pin-point precision. Some might find it a bit too eager to change direction at first, but we reckon BMW has judged the balance just right. Its sheer agility is as life-affirming for driving enthusiasts as it is immersive. Bravo, BMW.

With so much grip and control, this is not to say that the driver can’t hang the M4’s tail out every-which-way, since the chassis set-up allows for progressive oversteer, even in Road mode, along with as much drifting as your courage allows where safe. As with the best sports cars, the M4 is as steerable from the seat of your pants as it is using the throttle.

Finally, there’s the M Adaptive chassis tune, that at long last broadens the M4’s repertoire from motorway grand tourer and rural-road blaster to city slicker and urban warrior, thanks to the suspension’s ability to better-absorb a much wider array of terrible road surfaces. Comfort now lives up to its name, with the ride – though still firm – no longer hard or crashy around town, ushering in a new level of civility that won’t fatigue or aggravate you or your occupants. We're so happy to report this progress.

One area where BMW might want to keep improving, though, is the abundance of road noise intrusion over certain coarse chip bitumen. While easily muffled by the sweet sounds of the twin-turbo six, banging audio system or dropping the roof, it now seems more obvious that the rest of the car has smartened up so much.

A small fly in an otherwise hugely satisfying ointment.

It’s a tight build free of rattles and squeaks, but the ride is too firm when empty or lightly loaded, particularly in the leaf-spring rear suspension which feels every small bump and delivers a sharp kick in your back over larger ones.

Otherwise, the chassis performance is more than adequate with its four-wheel disc brakes and steering that’s responsive and nicely weighted. Engine refinement and noise insulation are not best in class, but at highway speeds the combined engine, tyre and wind noise is certainly low enough to allow conversations without raised voices. The Cummins fairly lopes along here, with only 1800rpm at 100km/h and 2000rpm at 110km/h.

It’s also quite an agile and energetic performer around town, particularly in Sport mode. Maximum torque of 385Nm from the Cummins diesel is far from the strongest in this category, but the Tunland’s relatively low kerb weight helps to compensate for it with brisk getaways from standing starts and good throttle response in city and suburban driving. 

To test its GVM rating we strapped 770kg into the load tub, which with driver was only about 50kg short of its 925kg payload limit. The rear springs compressed 50mm while the nose rose 18mm. This resulted in a near-level ride height and noticeably improved ride quality, with no major decline in steering or braking response.  

With this load it was a competent performer on a variety of sealed and unsealed surfaces, including some bush tracks on which we engaged in both high and low range 4x4. Back on the bitumen, it also coped well with our two kilometre, 13 per cent gradient set climb, maintaining the 60km/h speed limit in third gear at 2250rpm all the way to the top. 

Engine braking on the way down, though, was compromised by the auto transmission’s unusual shift protocols. With second gear manually selected (in sequential shift mode) it over-rode that selection and shifted up to third when the engine reached 3250rpm on over-run. We tried it again several times and got the same result.

Not sure if it’s an engine protection measure on Foton’s part (redline is 4000rpm) but it’s not a nice surprise when you’re heavily loaded on a steep descent and relying on engine braking to help restrain your speed.

Our only other gripes were poor radio reception on the AM band (too bad if you like talkback) and the cruise control, which stopped working during our test and would not switch back on. 

Its three-star (out of five) ANCAP safety rating is poor, with single airbags for driver and front passenger only. 

Bosch electronic stability control includes brake-force distribution and hill-start assist, but there's no trailer sway control or AEB. The rear seat offers three head restraints and lap-sash belts. There are also ISOFIX attachments on the two outer seating positions, but no top tethers. Foton says it has identified differences in ISOFIX fittings between China and Australia, which it is now addressing for future export models. 

We feel here is where the company drops the ball.

Trailing all of its main luxury car rivals (except Porsche) by two years, BMW only offers a three-year/unlimited kilometre warranty, as well as three years of roadside assistance.

BMW says its vehicles’ servicing is condition-based, depending on how they’re driven and other factors, with a dash warning appearing to let the driver/owner know when it’s time. We advise servicing your M4 annually or at every 10,000km, just to be sure.

No capped-price servicing system is offered. However, as long as the first one is paid for before the first service on a new vehicle, the ‘BMW Service Inclusive Basic packages’ is available at extra cost, covering scheduled servicing for three years/40,000km or five years/80,000km.

No prices are published for M models like the M4, but a normal 4 Series costs from $1800 for the five-year/80.000km package. You can bet an M4’s will cost more.

Expect a three year/100,000km warranty and service intervals of six months/10,000km whichever occurs first. Roadside assistance is also available.
