GWM Cannon vs Mercedes-AMG E63

What's the difference?

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.

The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.

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.

The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.

At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.

It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.

This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.

New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.

A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.

It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.

Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.

Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.

The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'

To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.

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.

At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.

The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.

Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.

The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.

Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.

Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.

There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.

The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.

The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.

Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.

So, first of all, let's get the price out of the way. At $253,900, before on-road costs, this car's competitive set is a bruising, all-German trio comprising the Audi RS 7 Sportback ($224,000), BMW M5 Competition ($244,900), and Porsche Panamera GTS ($309,500).

And no surprise, it's loaded with all the luxury features you'd expect in this part of the market. Here are the highlights.

On top of the standard performance tech and safety equipment fitted to the E 63 S (covered later in this review), you'll also find: Nappa leather trim (seats, upper dash, upper door cards, and steering wheel), MBUX multimedia (with touchscreen, touchpad, and 'Hey Mercedes' voice control), 20-inch alloys, three-zone climate-control, interior ambient lighting, auto LED headlights (with 'Active High Beam Assist Plus'), eight “energising comfort programs” (with 'Energising Coach'), an 'Active Multicontour' front seat package, the 'Air Balance' package (including ionisation), and keyless entry and start.

Also included are the the 'Widescreen' digital cockpit (twin 12.25-inch digital screens), 13-speaker Burmester audio with digital radio, Apple CarPlay and Android Auto, a panoramic sunroof, adaptive cruise control, a head-up display, augmented reality satellite navigation, 'Parktronic' self-parking, electric front seats, seat cooling and heating front (heated rear), heated front centre armrest, a power-adjustable steering column, auto rain-sensing wipers, a wireless device charger, illuminated door sills, as well Amazon Alexa, etc, etc, etc.

And our test car also featured a couple of tasty options. An exterior carbon package ($7500), and AMG's professional grade ceramic composite brakes ($15,900), for an as-tested price of $277,300.

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.

The E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.

Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.

And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.

AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.

Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.

That's a pretty hefty number, but in line with this car's proportions and performance potential.

And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.

There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.

Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.

Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.

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.

AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.

So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.

First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.

With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.

The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.

The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.

Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.

The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.

But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.

The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.

 There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.

The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).

The three-pointed star's white-coated boffins have gone to town on the E 63 S, and the car is as good as it currently gets in terms of active and passive safety technology.

You could argue this car's dynamic ability is its strongest contributor to crash-avoidance. But a broad suite of features, specifically designed to keep you out of trouble includes, forward and reverse AEB (with pedestrian, cyclist, and cross-traffic detection), traffic sign recognition, 'Attention Assist', 'Active Blind Spot Assist', 'Active Distance Assist', 'Active High Beam Assist Plus', 'Active Lane Change Assist', 'Active Lane Keeping Assist', and 'Evasive Steering Assist.' That's a lot of assists.

There's also a tyre pressure monitoring and pressure loss warning system, as well as a brake priming function (monitors release speed on the accelerator pedal, moving pads factionally closer to the discs when required), and brake drying (when the windscreen wipers are active the system periodically applies just enough brake pressure to wipe water off the brake rotors to optimise wet weather efficiency).

But if an impact is unavoidable the 'Pre-Safe Plus' system is able to recognise an imminent rear-end collision and fire up the rear hazard lights (at high frequency) to warn following traffic. It will also firmly apply the brakes once the vehicle is stationary to minimise the risk of whiplash injuries if the car's then hit from behind.

If the potential crash is coming from the side, 'Pre-Safe Impulse' inflates air chambers in the side bolsters of the front seat backrest (within a fraction of a second) moving the occupant to the side towards the centre of the car, away from the impact area. Amazing.

As well as that, there's an active bonnet to minimise pedestrian injuries, an auto emergency call function, 'Crash Response Emergency Lighting', even a first aid kit and hi-vis vests for all occupants.

For the record, the current E-Class received a maximum five-star ANCAP assessment in 2016.

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.

All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.

Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.

And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.
