Ford Puma vs Mercedes-AMG E63

What's the difference?

If a minimum price and maximum interior space are your priorities, then the Puma is not for you. Especially so in the flagship ST-Line V, which may seem too small and a tad cramped compared to, say, a Seltos, C-HR or ASX.

Where the Ford excels, typically, is in the way it encourages the keen driver while cosseting four occupants (and a surprising amount of their cargo). There's a poise and maturity to the way the Puma moves that puts it on a par with or even beyond some premium compact SUVs. Even the styling is a statement. If the badges (and dashboard) were covered, you might be convinced this cat is actually a Jag.

If all that is more important, then the ST-Line V is for you. The very antithesis, then, of the unassuming and unloved EcoSport the Puma usurps.

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.

If you search for the 1998 Puma coupe, you'll see some vague similarities with its modern SUV namesake, especially in their anthropomorphic face. It's in the eyes. There are also hints of Aston Martin (DBX), Porsche (Macan) and – let's face it – Mazda (CX-3).

Yet the real achievement lies in the way Ford has managed to make a 4.2-metre-long by 1.8m wide by 1.6m high crossover look so svelte, with the resulting balanced proportions, flowing lines and taut surfacing giving the Puma quite an athletic visual presence. After the EcoSport failure, head-turning looks were deemed paramount.

The extra girth gained by widening the Fiesta's platform allowed Ford's designers to create a muscular body that could also accommodate a metre-wide tailgate opening, while beneath the cargo floor is an exceptionally deep storage box, bringing better-than-expected practicality to boot.

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.

Compact yet spacious, the ST-Line V's interior has strong as well as weak points.

Let's start with the latter. The most obvious connection with the Fiesta is in the Puma's dashboard, which is largely shared between the two. After all the effort expended on the design and chassis, this is somewhat disappointing. There's nothing wrong essentially with the fascia's aesthetics or functionality – it's just that the look is humdrum and dated. What's needed is something with the visual wow factor as found in the latest Peugeot 2008, especially at this price point.

Yet Ford has at least tried to put some tinsel inside this most expensive version of its smallest SUV.

Stitched perforated leather seat facings, carbon-fibre-look trim and soft vinyl coverings in key touchpoint areas bring an upmarket look and feel, backed up by a now-familiar digital instrumentation layout, a lovely flat-bottomed three-spoke steering wheel, easy and intuitive multimedia interface and a wireless phone charger. That electronic cluster, by the way, changes colour and markings but doesn't have the scope of multimedia displays of, say, Audi's Virtual Cockpit. It's comparatively rudimentary.

Conversely, there's a solidity and quietness as well, offering a level of refinement that's usually found in more-premium Euro alternatives. We weren't expecting that, though of course this is a German Ford product.

Our test car also boasted a vast glass opening sunroof, adding to the opulence. With all this gear, the ST-Line V's cabin is properly appealing.

On the practicality front, entry and egress is pretty good, the driving position is excellent (thanks in no small part to a big amount of adjustability for both the steering column and seats), the front cushions themselves are sumptuously enveloping, while wide door pockets and a big glovebox obviously come in useful. And there's a USB-C outlet in the centre cubby between the seats. How modern.

However, rear vision out is poor, there are no seat warmers and some of the lower-lying plastics are a bit drab.

The back seat isn't really suitable for people over 175cm, as kneeroom is limited and taller scalps may scrape the ceiling with the twin-pane sunroof in situ. The latter also means no overhead grab handles.

But the backrest angle and cushions themselves are fine, even for longer journeys. Just don't expect to squeeze a third adult in the back unless rubbing shoulders won't bug you. Note, too, that the rear cushion does not slide or tilt forward to allow for a lower load area when the backrest is folded down. Pity.

There is a receptacle in both doors for small bottles but no cupholders whatsoever (how can Ford call itself an American company?), or face-level air vents – though the large dash vent outputs do reach the rear. Amenities such as USBs and cupholders are AWOL; and vision out from back there is limited by the high shoulder line. Tough if you're trying to peer out. Sorry, Fido.

The Puma's overall compact footprint and rear packaging clearly suggest that this is aimed at singles, couples, or couples with smaller kids/pets to transport around.

Still, for a small SUV, the cargo area isn't bad at all. The standard floor depth is fairly generous, with a long and flat loading area, but below that is a narrower yet deeper waterproof area, while under that again is a space-saver spare wheel. Clever. Also intelligent is the luggage cover that lifts automatically with the tailgate, as per Mazda's CX-5.

For the record, cargo capacity is rated at 410 litres with the 60/40 split-fold rear seats erect – or 1170L with them folded down flat. These figures far outstrip the CX-3.

To sum the cabin experience… it's far-better than its Fiesta-sourced dashboard may suggest, while the ST-Line V treatment goes a long way in helping justify the premium. That's a win.

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.

A multiple international engine-of-the-year winner, the compact and lightweight, 999cc 1.0-litre twin-cam three-cylinder turbo petrol unit is the sole choice for now. Driving the front wheels via a seven-speed dual-clutch transmission (DCT), it delivers 92kW of power and 170Nm of torque.

With no all-wheel drive option, there are instead five driving modes – Normal, Sport, Slippery (for snow) and Trail (gravel) applications, working on the traction, stability and transmission algorithms to mimic some of the benefits of AWD. In the ST-Line V, a set of paddle shifters are fitted in lieu of the sadly-absent manual gearbox.

Owners of the previous-shape Fiesta S and EcoSport would be familiar with the 1.0T's smooth and strident performance, though these 2010s models used a completely different type of DCT. This was the highly-publicised Powershift, which consisted of a dry-clutch system, and was prone to a multitude of problems and failures in the petrol-powered auto versions.

In contrast, the Puma adopts a next-generation transmission dubbed 7DCT300; related to the item found in some smaller Mercedes-Benz, Renault and Nissan models, it instead employs a more-robust wet-clutch system with a higher torque threshold, so promises to be far more durable and reliable than the problematic old dry-clutch unit.

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.

The Puma's official combined average fuel consumption figure is just 5.3 litres per 100km, which works out to 121 grams per kilometre. Fitted with a 42-litre fuel tank, the potential range averages out to almost 800km between refills.

Out in the real world, we managed an exceptional 6.2L/100km, no doubt helped by an ever-eager stop/start system (which, annoyingly, kills the air-con when it extinguishes the engine; we found ourselves constantly pressing that 'off' button as the days wore on). This figure was achieved in motorway-heavy driving scenarios, albeit loaded with holiday gear and with the air-con blaring.

So, we took another, urban-focused test, in lots of slow-moving traffic situations, and averaged a still-solid 8.0L/100km.

Note, that while the Puma requires 95 RON premium unleaded, it's also perfectly happy on – and is even recommended by Ford for – the cheapest petrol currently offered in Australia, 94 RON E10 unleaded. Either way, the ST-Line V is a frugal small SUV.

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.

If the Puma's pricing is complicated, its cabin surprising accommodating and its real-world efficiency particularly parsimonious, then the upward trajectory of pros over cons continues with performance that's downright spirited.

Around town first. A small-displacement engine plus a turbo plus a DCT usually spell interminable spells of lag when all the driver longs for is an instant and measured response to a right foot flexing down onto the throttle.

But the Ford largely sidesteps such pitfalls. Though momentarily hesitant at take-off, the three-pot turbo does then get down to business in no time, with a sustained and satisfying surge of thrust as the revs grow, accompanied by a lusty and raspy thrum that's entirely in keeping with the Puma's track-pants appearance. And it doesn't let up either, with speed building up strongly through the gears, and much more so than the mere 999ccs suggest. Great for overtaking, or taking over a rapidly diminishing gap in the peak-hour derby.

Selecting Sport (a fiddly action that's located too far from the driver for safe eyes-on-the-road operation) lights an even bigger fire in the Puma's belly, with punchier acceleration and a very attentive transmission tune, slicing seamlessly through the seven ratios, leaving you in awe that a heart so small can possess such deep lungs.

Where the Ford really leaves an indelible mark is its enthusiasm to corner just as keenly, armed with brilliantly slick steering and a planted chassis that is set up to both encourage and interact with the driver. Minimal body roll and lots of grip from a quality quartet of Continental tyres ensure the Puma can be punted about like a sporty little hatchback, while the electronic safety tech allowing just enough leeway for lots of fun before they gently reel everything back into line.

We cannot think of a more enjoyable small SUV. And, by the way, those same driver-assist systems provide exceptionally nuanced lane-keep and adaptive cruise-control intervention – certainly they're right up there with the premium SUV brigade.

Given that our Puma wore 215/50R18 rubber, on a 'sports' suspension tune, the ride around town is commendable, with ample cushioning from the rough stuff. There is some tautness to the ride, but it isn't hard or rough; the ST-Line V walks a fine line between urban-agility and surface-decay isolation. In other words, it's commendably relaxing to travel in.

At higher speeds, some road and tyre noises do permeate through inside, and those Dumbo door mirrors do create some wind whoosh, but overall, given how dynamic the chassis is, the Puma feels grown up and sophisticated.

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.

Ford offers the industry-average warranty of five-years/unlimited kilometres. Services intervals are every 12 months or 15,000km.

There is also a capped-price servicing scheme under the 'Ford Service Benefits' banner, with the first four years/60,000km of 'A and B' logbook services pegged at $299 per visit, and then between $320 and $560, for up to 12 years.

There is also a Ford loan car program, SYNC 3 map updates and Motoring Club Membership included during that time frame.

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.
