Ford Fiesta vs Mercedes-AMG E63

What's the difference?

The Fiesta ST is an addictive car to drive. It's a modern classic and hard to beat when it comes to engaging performance and smile-inducing dynamics. Add in excellent value for money and you have a certified performance car bargain. 

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 styling changes ushered in by the 2022 update are subtle. The Fiesta ST gains a revised front fascia with LED Matrix headlights, a larger grille with a repositioned Ford badge, and restyled bonnet and bumper. 

It gets a fresh 18-inch alloy wheel design and black tail-light surrounds at the rear. It also comes in two new exterior paint colours - 'Mean Green' and the 'Boundless Blue' of our test car.

The current-generation Fiesta ST has an appealing design that represents a clear evolution of its predecessor, and, arguably, it didn’t need much work this time around.

The ST’s sporty bodykit adds a touch of aggression but not in a boy racer sort of way. It’s a classic hatchback design with a bit of an edge. 

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.

As part of the update, the Fiesta ST gains new Recaro front sports seats that are firm and hug the body tightly. You feel well supported when cornering. The mix of synthetic leather and suede looks spot-on.

Like a number of sports-focused models, the ST features red stitching throughout the cabin - on the steering wheel, gearbox gaiter and air vent surrounds - and while it’s ubiquitous, it’s still a nice touch.

The chunky perforated leather steering wheel feels nice to touch, as does the metal gear knob. 

Cabin materials are a mix of soft-touch and hard plastics, and there’s carbon-fibre-look inserts on the dash.

There’s no denying Ford’s dash design is a huge improvement over the previous-generation Fiesta that ran from 2009, but the current model still lacks the polish of the VW Polo. It’s about on par with the Hyundai i20 N, although the Ford’s layout is a little busier.

In saying that, it’s hard to fault the cabin’s functionality. It has a deep central storage bin, which is larger than most cars in this category, a decent sized glove box, two-and-a-half cupholders in the centre console and storage for narrow bottles in the doors.

There’s a wireless charging dock behind the gear shifter, two USB ports (one in the storage bin and one next to the charger), as well as a 12-volt charger.

It’s nice to see the ST still has a manual park brake, too.

The facelift introduced a 12.3-inch fully digital instrument cluster, and while some may lament the loss of analogue dials, it’s nice to see Ford taking the opportunity to improve the tech.

The multimedia is housed in a smallish 8.0-inch digital screen sitting atop the centre stack and it runs Ford’s Sync 3 system. 

Sync 3 functions well, is hard to fault and the menu layout is easy to navigate, but it is being left behind by competitors with more modern and appealing graphics. The latest version in the new Ranger will no doubt be a major improvement, but we won’t be seeing it in this generation of Fiesta.

The diminutive size of the Fiesta ST is more apparent when sitting in the rear seats. It’s pretty tight behind my 183cm (6ft) driving position, with my knees hitting the rear of the front seats. 

It’s a cramped space that’s not designed for long trips by adults. It has redundant tiny rear-side windows behind the C-pillar, but on the plus side, there’s acres of headroom. 

It lacks rear-seat air vents and the closest USB port is in the front centre storage compartment. Taller bottles won’t fit in the doors and it lacks a centre fold-down armrest, but it has map pockets.

The rear seats are flat and the Fiesta has outboard ISOFIX points for child seats.

Realistically, most people buying a car like this aren’t using it to haul children around so think of it as a two-seater with handy rear-seat storage.

The rear seats fold 60/40 but not flat. A space-saver spare wheel lives under the boot floor and it has a high boot lip, meaning you have to lift items up and over to get them in. 

At 311 litres, it’s a decent sized boot with usable space. It’s just one litre more than the Hyundai i20 N, and six litres more than the Polo GTI.

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.

Under the Fiesta’s cute bonnet is Ford’s 1.5-litre three-cylinder turbocharged petrol engine delivering 147kW at 6000rpm and 320Nm at 4000rpm - the latter is an increase of 30Nm over the pre-facelift model.

Interestingly, it now matches the power and torque outputs of the Polo GTI. The i20 N pumps out 150kW and 304Nm.

The engine is exclusively paired to a six-speed manual gearbox - there is no auto transmission available - and it is front-wheel drive.

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.

Ford claims the Fiesta ST has an official combined cycle fuel use figure of 6.3 litres per 100 kilometres. 

After a week of predominantly inner city and freeway driving, we recorded a much higher 10.2L/100km. However, that was very shortly after an enthusiastic back-road blast to test its performance chops. We did see single-digit numbers throughout the week prior to that.

The Fiesta requires premium 95RON petrol and it has a 45-litre tank. CO2 emissions are 144g/km of CO2.

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.

It’s easy to find your ideal driving position in the Fiesta ST, thanks to the reach and height adjustable steering wheel and the adjustable seat.

Aside from the extra 30Nm dollop of torque, Ford hasn’t changed anything else about the Fiesta ST mechanicals for 2022, but arguably, it didn’t need to.

The pre-facelift model could cover 0-100km/h in 6.7 seconds, and while Ford has not revealed whether that has changed with the facelift, it feels about right.

It’s brisk from a standing start, without being neck-snappingly quick, but there is strong urge and a lack of noticeable turbo lag. There is, however, some axle tramp on take-off, particularly in the wet. We also detected some torque steer when pushing hard up a hill, but it was minimal. 

Speaking of, the little three-pot turbo engine is utterly unfazed by steep hills - it just keeps adding speed. A light kerb weight of 1218kg helps here. 

The three-pot turbo engine sounds wonderful when accelerating, and the Fiesta ST begs to be driven hard.

The engine is perfectly matched with the slick shifting six-speed manual gearbox that has lovely short throws and is a joy to use. Even if Ford offered an auto with the Fiesta ST, it would take away from the driving experience.

'Sport' mode ups the growl from the engine and throttle response, but it’s not a dramatic departure from 'Comfort' mode.

The ST’s strong brakes are bordering on sensitive, but the heavily weighted steering is incredibly sharp.

On a back road run, the front-wheel drive Fiesta ST comes alive, hugging corners confidently. 

On bends that would’ve seen many other cars come undone, the Fiesta’s tight, balanced chassis, grippy tyres and the standard mechanical limited slip differential ensure it maintains its composure.

The ride is undeniably firm, particularly around town in urban areas - you feel every speed bump. My partner found the ride a bit too much at times, but I was far more forgiving.

The Fiesta feels solidly built and has a level of refinement that’s missing from the likes of the Suzuki Swift Sport and Hyundai i20 N.

However, the cabin could do with more noise deadening materials as it can be quite rowdy at speed and on coarse chip roads. Another negative is the massive turning circle - a bit odd for a city-focused light hatchback.

But these are things I could happily live with. During my week with the Fiesta ST, I made any excuse to jump behind the wheel and go for a drive.

Me: “I’m just going to run to the shops to get pasta.”

My partner: “We’re not cooking pasta this week.”

Me: “Yeah but you never know when you need pasta. Bye!”

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.

The Fiesta is covered by Ford’s five-year/unlimited kilometre warranty and you get free roadside assistance and state/territory auto club membership each year that you service your car at a dealer, for up to seven years.
