GWM Cannon Alpha vs Aston Martin DB11

What's the difference?

The Cannon Alpha Ultra PHEV combines five-star safety, a confident warranty, lavish luxury and short-haul electric driving for a competitive price. However, from a pure workhorse perspective, its class-benchmark 3500kg tow rating is offset by a modest payload limit, plus an awkward spare tyre location which could be a deal-breaker for some tradies as it compromises working floor space and the securing of loads.

The Aston Martin DB11 AMR is fast, capable and beautiful. It has a unique character and charisma its Italian and German competitors can’t match. That said, some important media and safety-tech features are absent. So, it’s not perfect... just brilliant.

Our test vehicle shares the same body-on-frame chassis design, twin A-arm/coil-spring front suspension, four-wheel disc brakes and electric power-assisted steering as the model it replaces, but the previous leaf-spring live rear axle has been replaced by a multi-link coil-spring arrangement. External chrome has also been greatly reduced.

Its luxurious leather-accented interior has a spacious and classy feel with a panoramic sunroof and opulent mix of surface finishes, but some tradies might consider such indulgences too fancy for carting muddy-booted crews.

The PHEV’s larger rechargeable battery pack uses up all the underfloor space behind the rear axle usually occupied by a full-size spare tyre. As a result, the steel-rimmed spare has been moved to a conspicuous location in the load tub, which not only looks like an afterthought but is far from ideal for workhorse duties (see Practicality).

For a while there it looked like Aston Martin had fallen into the ‘everything looks the same’ trap, with Ian Callum’s breakthrough DB7 design in the mid-‘90s writing the script for the DB9 that followed, and heavily influencing everything else in the brand’s subsequent portfolio.

But in 2014, Aston’s design chief Marek Reichman sent a message with the DB10 Concept that things were about to change.

James Bond had Q and MI6 to thank for his DB10 company car in Spectre, but real-world Aston Martin customers were soon offered the DB11, which combined the muscularity of Reichman’s work on the ultra-exclusive One-77 from a decade earlier with the swooping, long-nosed proportions of his track-only Vulcan hypercar.

The hallmark of a well executed 2+2 GT is that it looks bigger in photos than it does in reality, and the DB11 is a perfect case in point.

Appearing limo-sized in our accompanying images, the DB11 is in fact 34mm shorter end-to-end than a Ford Mustang, but it’s exactly 34mm wider, and no less than 91mm lower in overall height.

And as any fashionista worth their salt will tell you, dark colours are slimming, and our ‘Onyx Black’ AMR, with gloss black 20-inch forged rims and black ‘Balmoral’ leather interior accentuated the car’s tightly drawn, shrink-wrapped surface treatment.

Signature elements in the shape of a broad, tapering grille, divided side vents, and sharply curved, two-level (smoked) tail-lights clearly identify the DB11 as an Aston Martin.

But the smooth integration of the car’s broad haunches (very One-77), gently tapering turret (optional exposed carbon) and flowing bonnet is masterful and fresh. The dash-to-axle ratio (the distance from the base of the windscreen to the front axle line) is Jaguar E-Type-esque.

And it’s all subtly aero-efficient, For example, the door handles fit flush to the body, the mirror housings double as mini ‘wings’, and the Aston Martin ‘Aeroblade’ system channels air running from carefully crafted openings at the base of the C-pillar, through the rear of the car to generate downforce (with minimal drag) across a lateral vent on the trailing edge of the bootlid. A small flap rises at “high speed” when more stability is required. 

The interior is all business, with a simple instrument binnacle showcasing a central 12.0-inch digital speedo-within-tacho combination, flanked by configurable engine, performance and media read-outs on either side.

Aston has form with squared-off steering wheels and the DB11’s is flat on the bottom and decidedly straight on the sides, affording a clear view of the gauges without compromising purpose. A leather and Alcantara trim combination is (literally) a nice touch. 

The teardrop-shaped centre stack sits in a slightly recessed section (optionally) lined with ‘carbon-fibre twill’, while the form and function of the 8.0-inch multimedia screen at the top will be immediately familiar to current Mercedes-Benz drivers, as the system, including the console mounted rotary controller and touchpad, is sourced from the three-pointed-star brand.

A band of proudly illuminated buttons across the centre includes gear settings for the transmission and a winged stop-starter in the middle. Strange, then, that the plastic knobs on the adjustable air vents look and feel so cheap and bland. This a $400k-plus Aston Martin, where’s the knurled alloy? 

Other highlights include elegant sports seats trimmed in a combination of premium leather and Alcantara. Aston offers various levels of leather and our car’s black ‘Balmoral’ hide is taken from the top shelf.

The key accent colour inside and out on our test example was a screaming lime green, picking out the brake calipers, centre strips on the seats, and contrast stitching throughout the cabin. Sounds awful, looks amazing.  

Our test vehicle’s substantial 2810kg kerb weight is 235kg heavier than its hefty Alpha Hybrid predecessor, due largely to the bigger battery and electric motor. That makes it about half a tonne heavier than numerous conventional turbo-diesel 4x4 dual cab utes.

This substantial kerb weight contributes to a sizeable 3495kg GVM, yet results in a 685kg payload rating which is modest compared to some turbo-diesel rivals with genuine one-tonne capabilities.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer, but with its 6745kg GCM (or how much it can legally carry and tow at the same time) that would require a 250kg reduction in payload (from 685kg to 435kg) to avoid exceeding the GCM.

While it’s unlikely owners would need to tow at the 3500kg maximum, it’s important to be aware of these numbers if the need arises, as that 435kg of payload could easily be used up by a crew of tradies before you could load any of their tools.

The vertical mounting of the spare wheel in the load tub not only reduces floor space and load volume but also restricts the securing of loads, given there’s no anchorage point accessible in the right rear corner of the tub.

So, all load straps extending rearwards must share the same left-side anchorage point, which is far from the ideal even spread provided by four-corner load restraint. This spare wheel location needs a rethink (perhaps a swing-away carrier favoured by 4x4 wagon owners would be better).

We also noted the big button on the two-way tailgate, which enables it to split into a pair of hinged doors, stopped working during our test. Fortunately, it could still open the tailgate as a conventional single unit.

There’s ample interior space, not only for front seat occupants but also those in the back. That includes tall people, given I’m 186cm and have at least 40mm of knee room when sitting behind the driver’s seat when set in my position.

There’s also about 80mm of rear headroom, despite the presence of a full-length sunroof which can often compromise this dimension. However, shoulder-room is tight for three adults, so two would be preferable for long trips.

Front-of-cabin storage includes a large-bottle holder and bin in each front door, plus a large glove box, overhead glasses holder and a pull-out compartment for the driver in the lower dash.

The centre console offers wireless phone-charging and a lidded box (with internal air-con flow available) and two small-bottle/cupholders. Another storage nook in the lower right-side of the console offers two USB ports, a 12-volt socket and enough space for a phone.

Rear passengers get a large-bottle holder and bin in each door, pockets on the rear of both front seat backrests and small pull-out drawers under each outer seat. The rear of the centre console also offers adjustable air-vents, a pair of USB ports plus controls for seat heating/cooling and the sliding rear window.

The fold-down centre armrest offers another wireless phone-charging pad, pop-out twin cupholders and a hidden compartment for storage of phones or other slimline items.

On one hand it’s hard to describe a supercar like the DB11 as practical when its primary purpose is to go ridiculously fast and look incredibly good in the process.

But this is, in fact, a ‘2+2’ GT, meaning a couple of occasional seats have been squeezed behind the front pair to allow obliging contortionists, or more likely small children, to enjoy the ride.

No one is claiming full four-seat capacity, but it’s a trick that has for decades made cars like Porsche’s 911 a more practical choice for high-end, high-performance sports car buyers.

At 183cm I can verify the chronically limited space back there, without anything in terms of connectivity, specific ventilation or storage options provided. Good luck, kids.

For those up front it’s a very different story. First, the doors are hinged to move up slightly as they swing out, which makes entry and egress a more civilised process than it might otherwise be. That said, those doors are still long, so it pays to pre-plan a workable parking spot, and the high-mounted, forward-facing interior release handles are awkward to use.

Storage runs to a box between the seats, complete with a two-stage electrically controlled lid, housing a pair of cupholders, an oddments space, two USB inputs and an SD card slot. Then, there are slim pockets in the doors, and that’s about it. no glove box or netted pouches. Just a small tray for coins or the key in front of the media controller.

And speaking of the key, it’s another strangely underwhelming part of the DB11 AMR’s presentation. Plain and insubstantial, it looks and feels like the key to an under-$20k budget special, rather than the heavy, polished and glamorous item you’d expect to be subtly placing on the table in your preferred three-hat restaurant.

The carpet-lined boot measures 270 litres, which is enough for some small suitcases and a soft bag or two. In fact, Aston Martin offers a four-piece accessory luggage set “expertly tailored to match the car’s specification.”

Don’t bother looking for a spare wheel, an inflator/repair kit is your only option in the case of a puncture.

Head into the $400k new car zone and expectations are understandably high. The DB11 AMR’s is a continent-crushing GT after all, and you want your fair share of luxury and convenience features to go with its huge performance potential.

For $428,000 (plus on-road costs), as well as the safety and performance tech (of which there’s plenty) covered in later sections, you can expect a lengthy standard features list, including a full-grain leather interior (seats, dash, doors, etc), Alcantara headlining, multi-function ‘Obsidian Black’ leather-trimmed steering wheel, electrically adjustable and heated front seats (with three memory positions), heated/folding exterior mirrors, front and rear parking sensors, and 360-degree ‘Surround View’ parking cameras (including front and rear cameras).

Also standard are cruise control (plus speed limiter), sat nav, dual-zone climate control, the electronic instrument cluster (with mode-specific displays), keyless entry and start, a multi-function trip computer, 400-Watt Aston Martin audio system (with smartphone and USB integration, DAB digital radio and Bluetooth streaming), plus the 8.0-inch touch-control multimedia screen.

Then there are LED headlights, tail-lights and DRLs, ‘dark’ grille, headlight bezels, and tailpipe finishers, 20-inch forged alloy rims, carbon-fibre bonnet vent blades and side strakes, dark anodised brake calipers and, to reinforce the car’s motorsport DNA, the AMR logo sits on the door sill plates and is embossed on the front-seat headrests.

Apple CarPlay and Android Auto functionality is a surprising omission, but our test car more than made up for it with a motherload of optional extras including an exposed carbon-fibre roof panel, roof strakes and rear-view mirror caps, as well as ventilated front seats, the vivid ‘AMR Lime’ brake calipers, plus a ‘Dark Chrome Jewellery Pack’ and ‘Q Satin Twill’ carbon-fibre trim inlays to add presence in the cabin. Along with some other bits and pieces this adds up to an as-tested total of $481,280 (before on-road costs).

The Alpha PHEV drivetrain consists of a 2.0-litre, four-cylinder, turbo-petrol engine that produces 180kW of power and 380Nm of torque. This is paired with an electric motor that adds another 120kW/400Nm, so combined they officially produce 300kW and 750Nm.

The electric motor draws its energy from a 37.1kWh lithium-ion rechargeable battery. GWM claims it can be charged from 30 to 80 per cent in less than 30 minutes using 50kW DC charging, or around 6.5 hours using AC charging.

It also has up to 6.0kW of V2L (Vehicle to Load) functionality, using a dedicated adapter cable which plugs into the vehicle’s charging port and provides a standard three-pin AC outlet for numerous electric tools and appliances.

The nine-speed torque converter automatic, which offers sequential manual-shifting using steering wheel-mounted paddles, is paired with the familiar Borg Warner ‘Torque on Demand’ 4x4 system.

For road use, this has three selectable drive modes ('Standard'/'Sport'/'Eco') with the centre differential remaining unlocked to automatically adjust torque delivery between the front and rear wheels in response to any loss of traction.

For off-road use, selecting '4H' (4x4 High Range) or '4L' (4x4 Low Range) locks the centre differential to provide an even 50:50 torque split between the front and rear wheels. 4L traction can be optimised by engaging the front and rear diff-locks.

The DB11 AMR’s (AE31) 5.2-litre, twin-turbo V12 is an all-alloy unit, tuned to deliver 470kW (up 22kW on the old model) at 6500rpm, while retaining the previous DB11’s 700Nm of maximum torque from 1500rpm all the way to 5000rpm.

As well as dual variable camshaft timing, the engine features a water-to-air intercooler and cylinder deactivation, which allows it to run as a V6 under light loads.

Drive goes to the rear wheels via a ZF-sourced eight-speed (torque converter) auto transaxle with column-mounted paddles, recalibrated for faster shifting in more aggressive Sport and Sport+ modes. A limited-slip differential is standard.

GWM claims official combined average consumption of only 1.7L/100km when the highly-charged battery allows most driving to be done in pure electric mode. GWM also claims an official ‘low charge’ figure of 7.9L/100km, when the battery is depleted and the petrol engine is doing most of the work.

It has an NEDC electric-only driving range of up to 115km and a ‘hybrid’ driving range (petrol engine and electric motor combined) of up to 1060km. The petrol engine drinks standard 91 RON unleaded.

The dash display was showing average petrol consumption of 6.4L/100km at the completion of our 324km test, which comprised a mix of suburban, city and highway driving of which about one third was hauling a heavy payload. This was lineball with our own figure of 6.2 based on fuel bowser and tripmeter readings.

Starting with 90 per cent battery charge, we completed 72km of electric-only driving before it automatically switched to hybrid mode when the charge reached 14 per cent. The system would not allow charge to drop lower than that for the remainder of our test, which was conducted in hybrid mode.

So, based on our own test figures, GWM’s claim of more than 1000km of hybrid driving range is credible from its combined 37.1kWh battery and 75-litre fuel tank capacities.

Minimum fuel requirement for the DB11 AMR is 95 RON premium unleaded and you’ll need 78 litres of it to fill the tank.

Claimed economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 11.4L/100km, the big V12 emitting 265g/km of CO2 in the process.

Despite standard stop-start and cylinder deactivation tech, in roughly 300km of city, suburban and freeway running we recorded a figure exactly nothing like that, according to the on-board computer we more than doubled the claimed number on ‘spirited’ drives. The best average figure we saw was still in the high teens.

It has good steering feel with sophisticated ride quality, the latter thanks to four-coil suspension and substantial sprung weight which helps iron out the bumps and deliver a ride that’s more SUV than ute.

Flatten the accelerator from a standing start and up to 750Nm of torque responds with impressive force, even though you can feel that every one of those Newton metres is required to overcome more than 2.8 tonnes of inertia to get this jigger moving swiftly.

Although the option of sequential manual-shifting is available using the steering wheel paddles, we spent most of the test in auto mode as it felt like it was getting the best out of this complex drivetrain.

It’s a competent highway cruiser, too, with the petrol engine requiring 2200rpm to maintain 110km/h with low noise levels.

To test its GVM rating we forklifted just over half a tonne (505kg) into the load tub, which with driver equalled a 600kg payload that was less than 90kg under its limit. The rear coil springs compressed about 50mm, but there was no evidence of bottoming-out on our test route.

Ride, handling and braking were largely unaffected, along with the drivetrain which made light work of our 13 per cent gradient, 2.0km set climb at 60km/h.

Engine-braking on the way down, in a manually-selected second gear, was equally impressive. It never exceeded the 60km/h speed limit, even though its total vehicle weight of around 3.5 tonnes was being restrained by only a 2.0-litre four and regenerative braking.

The moment you press the starter the DB11 begins a theatrical performance worthy of the Royal Shakespeare Company.

A high-pitched whine reminiscent of a Formula One air-starter precedes a raucous blast of exhaust noise as the twin-turbo V12 bursts into life. 

It’s spine-tingling, but for those wanting to remain on good terms with their neighbours a quiet-start setting is available.

At this point, rocker buttons on either side of the steering wheel set the tone for what follows. The one on the left, marked with a shock-absorber graphic, allows you to scroll the adaptive damping set-up through Comfort, Sport, and Sport+ settings. Its ‘S’ branded partner on the right facilitates a similar trick with the drivetrain. 

So, throwing urban serenity out the window, we pushed into maximum attack mode for the engine, and by extension the exhaust, selected D and began to enjoy the first act.

A launch-control function is standard, so purely in the interests of science we explored its function and can confirm it works exceptionally well.

Aston claims the DB11 AMR will accelerate from 0-100km/h in just 3.7sec, which is properly fast, and two tenths of a second faster than the standard DB11 it replaces. 

Keep the pedal pinned and two things will happen; you’ll reach a maximum velocity of 334km/h and generate headline news across the country while making your way directly to jail.

With 700Nm available from just 1500rpm, and remaining on tap to 5000rpm, mid-range thrust is monumental and the thundering exhaust note accompanying it is the stuff automotive dreams are made of.

Peak power of 470kW (630hp) takes over at 6500rpm (with the rev ceiling sitting at 7000rpm) and delivery is impressively linear, without a hint of turbo hesitation.  

Aston claims the DB11 AMR will accelerate from 0-100km/h in just 3.7sec, which is properly fast.

The eight-speed auto is simply superb, picking up gears at just the right point and holding on to them for exactly the right amount of time. Select manual mode and the slender shift levers on either side of the steering column allow even more control.

In Sport and Sport+ drivetrain modes the howling exhaust is accompanied by an entertaining array of pops and bangs on up and down shifts. Bravo!

The DB11 AMR is underpinned by an ultra-stiff bonded aluminium chassis, with a double wishbone front/multi-link rear suspension set-up attached to it.

Spring and damper rates are unchanged from the previous DB11 and even on enthusiastic back-road runs we found suspension in Comfort and driveline in Sport+ to be the best combination. Flicking the shocks into Sport+ is best kept for track days. 

Steering is (speed dependent) electrically power-assisted. It’s beautifully progressive, yet pin-sharp with excellent road feel.

The big 20-inch forged alloy rims are shod with high-performance Bridgestone Potenza S007 rubber (255/40 front – 295/35 rear), developed as original equipment for this car and Ferrari’s F12 Berlinetta.

They combine with the 1870kg DB11’s near perfect 51/49 front to rear weight distribution and standard LSD to deliver confidence-inspiring balance and ferocious power down on (quick) corner exit.

Braking is handled by huge (steel) ventilated rotors (400mm front – 360mm rear) clamped by six-piston calipers at the front and four-piston at the rear. We might have put them under decent pressure from time-to-time, but stopping power remained prodigious and the pedal firm.

In the calm of urban traffic the DB11 AMR is civilised, quiet (if you prefer) and comfortable. The sports seats can be adjusted to grip like a vice at speed or provide more breathing room around town, the ergonomics are spot-on, and despite its striking looks, all around vision is surprisingly good.

Overall, driving the DB11 AMR is a special event, flooding the senses and raising the heart rate no matter what the speed.

Big speed demands serious active and passive safety, and the DB11 comes up short on the former.

Yes, there’s ABS, EBD, EBA, traction control, Dynamic Stability Control (DSC), Positive Torque Control (PTC) and Dynamic Torque Vectoring (DTV); even a tyre-pressure monitoring system, and the surround view cameras.

But more recent crash-avoidance tech like active cruise control, bling-spot monitoring, lane-departure warning, rear cross traffic alert, and especially AEB, are nowhere to be seen. Not great.

But if a crash is unavoidable there’s plenty of back-up in the form of dual-stage driver and passenger front airbags, front side (pelvis and thorax) airbags, as well as curtain and knee airbags.

Both rear-seat positions offer top tethers and ISOFIX anchors for baby-capsule and child-seat location.

The DB11 hasn’t been assessed for safety performance by ANCAP or EuroNCAP. 

Warranty cover is seven years/unlimited km with an eight years/unlimited km traction battery warranty and seven years of roadside assist.

Scheduled servicing is every 12 months/15,000km whichever occurs first. GWM offers seven years of capped-price servicing totalling $4615, or an average of $659 per service.

While Kia leads the mainstream market with a seven-year/unlimited km warranty, Aston Martin sits further back with a three-year/unlimited km deal. 

Servicing is recommended every 12 months/16,000km, and an extended, transferable 12-month contract is available, including everything from provision of a taxi/accommodation in the event of breakdown, to coverage of the vehicle at “official Aston Martin organised events.”
