BMW M8 vs GWM Cannon

What's the difference?

With dramatic looks, a luxurious spec, and impeccable quality, the BMW M8 Competition Gran Coupe remains supremely well controlled as it delivers eye-widening performance and amazing dynamics. But there’s an ‘edge’ to the experience you need to be ready for. If I was determined to head for the Aussie ‘fast lane’ in a BMW 8 Series Gran Coupe I’d opt for the M850i and pocket a lazy $71K (enough for a cheeky M235i Gran Coupe to add to your collection).

The latest version of the Cannon ute displays commendable improvement in key areas like drivetrain and chassis tuning, along with a benchmark 3500kg tow rating, heaps of standard equipment and a generous warranty for a list price well under $50K. For a tradie on a budget, it represents value that's hard to ignore.

Want to start a vigorous car enthusiast discussion (more a verbal punch-up)? Simply ask whether a four-door car can be a coupe.

Traditionally, the answer is no, but over time numerous automotive brands have applied that description to cars with more than two doors, including SUVs!

So, here we are. A four-door ‘Gran Coupe’, and the M8 Competition version retains the smoothly tapering turret and frameless side glass that help give selected BMW four-door models the same swoopy, coupe look.

At close to 4.9m long, a fraction over 1.9m wide, and under 1.4m high, the BMW 8 Series Gran Coupe has a firmly planted, low-slung, wide-track stance. Always a subjective call, but I for one, think it looks stunning, especially in our test car’s ‘Frozen Brilliant White’ matt paint finish.

In an era of comically oversized BMW grilles, things are relatively under control here, with a bright black finish applied to that ‘kidney grille’, as well as the huge front bumper air intakes, front splitter, front fender vents, exterior mirrors, window surrounds, 20-inch rims, lip spoiler on the boot, rear valance panel (incorporating a functional diffuser), and quad exhaust tips. The roof’s black, too, but that’s because it’s made of carbon-fibre.

Overall the M8 Competition Gran Coupe is a compelling combination of strong, confident character lines along the bonnet and lower flanks, with tightly wrapped curves following the high hip line, and more organically irregular, yet distinctly BMW shapes in the head- and tail-lights. 

The interior is a beautifully balanced design with a broad centre console sweeping up to the middle of the dash and wrapping around to focus on the driver, in typical BMW fashion.

 The multi-adjustable sports front seats are immaculate, with high-end quilting in the centre section matching a similar treatment in the doors. The dark grey (full) leather trim is offset by carbon and brushed metal trim elements for a cool, calm and focused feel.

Crack the bonnet open and a spectacular ‘BMW M Power’ carbon cover dressing the top of the engine is guaranteed to impress friends and family.

The upgraded Cannon brings refreshed exterior styling, with the front fascia featuring a new grille and bumper design, larger fog lights and more subtle use of chrome highlights.

At the rear there’s more prominent (and permanent) brand identification with bold ‘GWM’ lettering embossed on the tailgate panel, which is a welcome blast from our pick-up past.

The spacious interior design has also been enhanced with use of what GWM calls ‘premium materials’ including soft-touch surfaces on the dash and door panels along with subtle chrome accents.

There’s also a new steering wheel and the centre console has been redesigned with less buttons and dials (not always a good thing) topped by the new multimedia touchscreen.

Of the M8 Competition Gran Coupe’s 4867mm overall length, 2827 of it sits between the front and rear axles, which is a pretty healthy wheelbase for a car this size (and 200mm more than the 8 Series two-door coupe).

Space up front is generous, and one upside of a four-door, rather than two-door coupe, is you’re not struggling quite so much for space to get in and out when parked next to other cars.

Once inside, there’s plenty of storage up front, with a large lidded box/armrest between the front seats, twin cupholders in the centre console, as well as another covered area for wireless phone charging and extra bits and pieces in front of that. Long door pockets provide space for bottles, and the glove box is a decent size. There’s 12V power as well as USB sockets for media connection, with charging outlets in support.

At first glance you’d swear the rear seat was designed as a two-seater only, but when push (literally) comes to shove a centre passenger can squeeze in, legs straddling the rear console.

In terms of legroom, at 183cm (6’0”) I could sit behind the driver’s seat set for my position with knee room to spare, but headroom is another matter, with my noggin making solid contact with the soft Alcantara headlining. It’s the price you pay for this car’s racy profile.

There’s a neatly trimmed storage box and two cupholders in the fold-down centre armrest, plus door pockets with enough room for small bottles. The rear console houses dual climate controls, twin USB power sockets, and a small oddments tray, as well as buttons for the optional rear seat heating fitted to our test car ($900).

The 440-litre boot is a bit like the car itself - long and wide, but not very high. The rear seat split-folds 40/20/40 if you need more space, and the boot lid is automatic with a hands free function. But don’t bother looking for a spare of any description, a tyre repair kit is your only option.

With its 2230kg kerb weight and 3225kg GVM, the Cannon Ultra has a 995kg payload rating (that’s close enough to a ‘one-tonner’ by our measure) and the latest upgrades include an increase in braked tow rating from the previous 3000kg to the class-benchmark 3500kg.

However, with its 6200kg GCM (or how much it can legally carry and tow at the same time) our test vehicle would require a substantial payload reduction of more than half a tonne (525kg) to tow its maximum trailer weight (but it’s not alone there).

And that would leave 470kg of payload capacity, most of which could be used up by the weight of a hefty five-member working crew before you could think about loading any of their tools and other equipment.

Fact is, few (if any) owners would need to tow 3500kg, but it’s important to be aware of these numbers if you do plan to tow that heavy and want to stay on the right side of the law.

The square load tub is 1520mm long and wide and 540mm deep, but with 1146mm between the rear wheel-housings it won’t fit a standard Aussie pallet. However, it will accommodate Euro pallets, if hauling such payloads is important.

The tub’s internal surfaces are protected by a spray-in liner and there are load-anchorage points front and back, with the rears close to floor level (ideal for all loads) and the fronts near the tops of the sidewalls (not ideal for low loads). The tailgate is equipped with hydraulic dampers to assist opening/closing and the handy fold-out step allows easy entry to the load tub.

Cabin storage includes a bottle holder and bin in each front door, a small lower dash compartment on the driver’s right and a slender bin above the glove box on the passenger side.

The centre console has a wireless phone-charging pad, 12V socket and two USB ports up front, plus cup/small-bottle holders and a lidded box at the back with an internal air conditioning cooling vent and sliding upper storage tray.

The rear seat has adequate legroom even for tall people, given I’m 186cm and have about 60mm of knee clearance when seated behind the driver’s seat in my position.

Headroom is adequate though not as generous and the deep contour in the roof lining to allow for the sunroof can make tall rear passengers feel a bit closed-in.

Shoulder room can also be squeezy for three large Aussies, so like all dual cab utes short of a full-size US pick-up it’s okay for short trips but ideal for two on longer drives.

There’s a bin and bottle-holder in each rear door and pockets on both front seat backrests. The 60/40-split seat bases can also fold up and by stored vertically for more internal load space, or to access wheel-changing equipment.

Our test vehicle is the Ultra model grade, which sits above the entry-level Lux and below the Vanta and top-shelf XSR in the four-model Cannon range.

Like its siblings, the Ultra comes standard with a bigger 2.4-litre four-cylinder turbo-diesel engine sourced from its larger Alpha stablemate and new nine-speed automatic for $41,990 plus on-road costs ($43,490 drive-away).

Even with its optional 'Pittsburgh Silver' premium paint, which adds $595, that pricing represents compelling value given you need at least $50K just to get into a relatively spartan base-model Ford Ranger XL or Toyota HiLux Workmate 4x4 dual cab ute equivalent.

The Ultra has heaps of standard equipment, given that the entry-level Lux on which it’s based includes 18-inch two-tone chrome alloy wheels with 265/60R18 tyres and a full-size steel spare, chrome sports bar, LED lighting including DRLs, side-steps, roof rails, spray-in tub-liner, rear parking sensors, reversing camera, tyre pressure monitoring, driver’s 7.0-inch digital instrument cluster and six-speaker audio with a 12.3-inch multimedia touchscreen offering digital radio, Apple CarPlay/Android Auto connectivity and more.

To this list the Ultra adds an electric sunroof, tailgate step and rear privacy glass, plus leather-accented seats with power-adjustable front buckets equipped with heating and cooling.

The steering wheel is also heated plus there’s a USB port for a dashcam, ambient lighting, auto-dimming rear view mirror, 360-degree camera view and front parking sensors.

The M8 Competition is powered by an all-alloy, 4.4-litre twin-turbo V8 engine, featuring direct-injection, as well as the latest version of BMW’s ‘Valvetronic’ variable valve timing and ‘Double-VANOS’ variable camshaft control, to produce 460kW (625hp) at 6000rpm, and 750Nm from 1800-5800rpm.

Designated ‘S63’, the engine’s two twin-scroll turbos are located, along with a cross-bank exhaust manifold, in the engine’s (90-degree) ‘hot vee.’ 

The idea is consistent transmission of exhaust energy to the turbos for improved response, with the reversal of usual practice completed by inlet manifolds positioned on the engine’s outer edges.

Drive goes to all four wheels via an eight-speed ‘M Steptronic’ (torque converter) auto transmission with ‘Drivelogic’, and dedicated oil cooling, as well as BMW’s ‘xDrive’ all-wheel drive system.

The xDrive set-up is built around a central transfer case housing an electronically-controlled, variable multi-plate clutch, with front to rear drive distribution set to a default 40:60 split.

The system monitors multiple inputs including, wheel speed (and slip), acceleration and steering angle, and is able to vary the ratio up to 100 per cent rear thanks to the ‘Active M Differential.’ 

The Cannon's engine capacity has increased 20 per cent by adopting the Alpha's 2.4-litre four-cylinder turbo-diesel. It produces 135kW of power at 3600rpm and 480Nm of torque between 1500-2500rpm, which represents a 12.5 per cent power increase and 20 per cent more torque.

This is paired with GWM’s new homegrown nine-speed torque converter automatic (previously eight-speed) which has overdrive on the top three ratios and there are steering wheel paddle-shifters for sequential manual-shifting.

The 4x4 system is a ‘torque on demand’ design that transmits power to the rear axle under normal driving conditions to optimise fuel economy, but automatically sends power to the front axle if a loss of rear axle traction is detected.

It also offers a choice of selectable drive modes comprising 'Normal' (default), 'Sport' and 'Eco', plus 4H (4x4 High Range) and 4L (4x4 Low Range). The latter is only for the rough stuff, where the selectable electronic rear diff-lock could also come in handy.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.4L/100km, the M8 Competition emitting 239g/km of CO2 in the process.

Despite the standard auto stop/start function, over a week-long combination of city, suburban, and freeway running we recorded a (dash-indicated) average of 15.6L/100km.

Pretty thirsty, but not outrageous when you consider this car’s performance potential, and the fact that (purely for research purposes) we exploited it regularly.

Recommended fuel is 98 RON premium unleaded, and you’ll need 68 litres of it to fill the tank. That equates to a range of 654km in line with the factory claim, and 436km using our real-world number as a guide.

GWM claims official combined consumption of 8.4L/100km and the dash display was showing 9.6 at the completion of our 321km test, which comprised the usual mix of suburban, city and highway driving, of which about one third of that distance was hauling its maximum payload. The engine auto start/stop function was switched off for the duration.

Our own figure of 9.7L/100km, crunched from actual fuel bowser and tripmeter readings, was line-ball with the Cannon’s onboard calculation, which proved its accuracy. It also validated our test vehicle’s real-world sub-10L/100km consumption, which is excellent for a two-tonne-plus ute and gets a big thumbs-up from us.

Therefore, based on our test figure, you could expect a real-world driving range of around 800km from its 78-litre diesel tank.

There’s something teutonically symmetrical about the way the M8 Competition Gran Coupe delivers its prodigious thrust.

Peak torque of no less than 750Nm is available from just 1800rpm, remaining on full song across a broad plateau all the way to 5800rpm. Just 200revs later (6000rpm) peak power of 460kW (625hp!) takes over to finish the job, with the rev ceiling sitting just over 7000rpm.

That’s enough to slingshot this 1885kg bruiser from 0-100km/h in 3.2 seconds, which is supercar fast. And the engine and exhaust noise produced by the 4.4-litre twin-turbo V8 during such rapid acceleration is suitably brutal, courtesy of electronically-controlled flaps in the system opening up. 

On a more civilised drive you can reduce the exhaust noise via an ‘M Sound Control’ button on the centre console.

The eight-speed auto is fast and positive, especially in manual mode, which dials up the fun via wheel-mounted paddles. And when it’s time to direct this car’s forward momentum into lateral movement BMW has brought in the engineering heavy artillery.

Despite its frameless door body structure the M8 Competition Gran Coupe feels solid as a rock thanks in no small part to its ‘Carbon Core’ construction, using four primary components - carbon-fibre-reinforced plastic (CFRP), aluminum, high-strength steel, and magnesium.

Then the ‘Adaptive M Suspension Professional’ (with active anti-roll stabilisation), the tricky xDrive continuously variable AWD system, and active M Sport diff combine to keep everything under control.

Suspension is a double wishbone front, five-link rear arrangement, with all key components in alloy to minimise unsprung weight. In concert with the electronic wizardry on-board, it helps keep the M8 buttoned down with only modest body roll in enthusiastic cornering, as the rear-biased AWD system seamlessly distributes drive to the axle and wheels that can make best use of it.

The price you’ll pay for the track-ready tune is in compromised ride comfort. Even in the ‘Comfort’ setting, the M8 Competition is firm, and feels corrugations and imperfections to a surprising degree.

An alignment of the BMW 8 Series planets left me with the keys to this car and the M850i Gran Coupe (also using the Carbon Core body) at the same time, and the difference between their softest settings is appreciable.

Also be aware that at 12.2m the M8 Gran Coupe’s turning circle is substantial, and it’s just as well all that camera, sensor and self-parking tech is available to help you guide this ship into port.

The M8’s electrically-assisted, variable-ratio steering features an ‘M’ specific calibration to deliver satisfying precision and good road feel. But in similar fashion to the ride a noticeable amount of unwelcome feedback comes through to the wheel.

The fat Pirelli P Zero rubber (275/35 fr / 285/35 rr) grips hard, and the monster brakes (ventilated all around, with 395mm rotors and six-piston calipers up front) wash off speed without fuss or fade.

But overall, you’ll have to live with a less refined drive when you sign on for the M8 Competition. Straight away it feels faster but lacks the M850i’s lighter touch. No matter which drive or suspension mode you select, responses are more aggressive and physical.

To fully explore and enjoy the M8 Competition’s abilities it feels like the race circuit is its most appropriate habitat. On the open road, the M850i is all the Gran Coupe you’re going to need.

Even though there’s no adjustment for base-cushion rake or lumber support on the driver’s seat, we didn’t suffer any discomfort during our test. There are also three steering wheel assist modes to choose from comprising 'Light', 'Comfort' (default) and 'Sport'.

The new 2.4-litre engine effectively fills the gap that existed with the previous 2.0-litre, which felt underdone given this vehicle's size and weight. The big 20 per cent increase in torque is a noticeable improvement, as it pulls strongly from low rpm with gearing that keeps it within its peak zone most of the time.

It’s also relatively smooth and quiet and the three drive modes optimise performance in each setting. The Sport mode provides a noticeable increase in response, which in combination with the same setting for the steering is the most engaging drive experience.

The refined nine-speed auto is a sweet-shifting transmission in either auto or manual mode.

We were also pleasantly surprised by a big improvement in ride and handling, as this latest version of the Cannon feels like it finally has the beefier spring rates and damper settings this ute has been crying out for.

It’s also an effortless highway cruiser, with the overdriven top gear ensuring the engine requires less than 1800rpm to maintain 110km/h. However, although wind and engine noise is pleasantly low at these speeds, we did notice tyre noise emanating from the rear tyres into the cabin.

To test its GVM rating, we maxed out the payload to 990kg. This compressed the rear leaf-springs about 60mm, leaving around 40mm of static bump-stop clearance which ensured no bottoming-out on our test route.

It felt stable and sure-footed and the new drivetrain made light work of our 13 per cent gradient, 2.0km-long set climb at 60km/h, displaying ample pulling power in fourth gear to easily haul this load to the summit.

Engine-braking on the way down, in a manually-selected second gear, was arguably the best we’ve experienced in a sub-3.0-litre turbo-diesel with almost a tonne on its back.

Our only gripe is the emergency lane-keeping assist function, which needs more refinement as it creates weird fluctuations in steering weight and aggressively tugs at the wheel when you get anywhere near a white line.

Fortunately, this can be disabled in the vehicle settings menu, but unfortunately must be switched off before each drive.

The Cannon has a five-star ANCAP rating awarded in 2021 (expires 2027) and comes with seven airbags (including full-length side-curtain and centre-front), AEB including junction assist, front collision warning (pedestrian and cyclist), rear collision warning, rear cross-traffic alert with brake, blind-spot monitoring, lane-keeping, traffic sign recognition, trailer sway control, adaptive cruise control and lots more.

Junior tradies get ISOFIX child-restraint anchorages and top-tethers on the two outer rear seating positions.

BMW offers a three year/unlimited km warranty, which is at least a couple of years off the mainstream market pace, and lagging other premium players like Mercedes-Benz and Genesis, both sitting at five years/unlimited km.

Roadside assistance is included for the duration of the warranty period, and the standard ‘Concierge Service’ provides everything from flight information, to global weather updates, and restaurant recommendations, from a real human.

Technically, service is ‘condition based’ with the car telling you when it’s time to hit the workshop, but you can use every 12 months/15,000km as a guide.

BMW Australia offers ‘Service Inclusive’ packages that require customers to pre-pay for servicing, allowing the cost to be covered off in finance or leasing packages and reducing the need for concern about paying for maintenance further down the track.

BMW says there are different packages available, from three to 10 years, or between 40,000 and 200,000km.

Like all GWM Cannons, our test vehicle comes with a generous seven-year/unlimited km warranty, which includes five years of roadside assist. Apart from the first service at 12 months or 10,000km, scheduled servicing is every 12 months/15,000km, whichever occurs first.

GWM offers capped-pricing for the first five scheduled services (60 months or 70,000km), which totals $2530, or an average of $506 per service.
