Mercedes-AMG E63 vs Alfa Romeo Giulia

What's the difference?

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 Giulia is a love letter to the increasingly lost art of the sporty executive sedan. As refined as it is beautiful and oh-so elegant to drive, it’s a reminder of why we always love Alfa Romeo, even when the odds are against it.

Emotional cars like this are hard to come by and they will soon be gone, replaced by something new. The future is not necessarily worse, but it will be different, so if a sporty European sedan with a combustion engine is calling out to you don’t miss your opportunity to drive the Giulia while it still exists in this form.

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.

Like any good Alfa Romeo should be, the Giulia is a work of art. It’s sleek, sharp, and immaculately proportioned.

This most recent update has artfully refined a formula too good-looking to mess with. The increasingly dorky headlamps from the previous car have been swapped out for a more contemporary all-LED set, with a three-bar DRL pattern.

The grille has also been tweaked for this update for a more modern style, and the Veloce is now graced with the iconic and more aggressive sport two-tone alloy wheels in the traditional five-hole 'tele-dial' style.

It’s effortlessly attractive, and instantly recognisable as an Alfa on the road. I can’t think of a better way to stand out in today’s executive sedan landscape.

The interior has received less of an upgrade for the 2024 model year, with the same core parts. The major change is the old-school analogue instrument cluster being swapped out for a slick 12.3-inch digital unit.

The puzzling thing about this is the 8.8-inch central multimedia screen hasn’t been upgraded in-kind, making a strange contrast between the sharp and fast digital instruments, and the laggy and dull multimedia panel.

At least it effortlessly sits behind the curvaceous design of the dash as to not interrupt a good shape.

There are of course plenty of other touches which I love. The leather seats look and feel the part, as do the real metal paddle shifters which float behind the simple yet refined and sporty steering wheel.

The push-to-start button on the wheel is reminiscent of other Italian sports machines, while the tasteful smattering of leather, gloss plastic, and textured surfaces keep the premium feel on-track.

Some areas I’m not so keen about: Some of the interior plastics, particularly for buttons and toggles, feel cheaper than they should, and the door cards are oddly basic considering how much attention has been given to every other part of this car’s look and feel.

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.

The Giulia is an old-school low-slung sports sedan. Many will prefer the SUV sensibilities of the Stelvio, with its bigger hatch-opening boot, and its higher ride height can better accommodate less mobile passengers, and makes it easier to fit child seats and the like.

For those willing to trade those things away for a superior drive experience, the Giulia is still solid to live with every day, but has a few drawbacks.

For example, those strangely basic door cards offer only a tiny map pocket with a nook I’d hardly describe as a bottle holder.

The centre console offers two larger bottle holders with variable edges, but there’s also not much else in the way of storage in the cabin aside from a smaller-than-average glove box and armrest console box.

The big win for me is the physical dial set and shortcut buttons for all the key climate functions, making it easy to operate while you’re concentrating on driving.

At least the seats are well bolstered, and front passengers are treated to plenty of adjustability. Visibility is okay, and it was easy for me to find a comfortable driving position at 182cm tall.

The rear seat is a similar story. It’s tighter, and you have to duck down below the roofline to get into it.

Once inside, I was pleasantly surprised to find enough room for my knees and somewhere for my feet to slide behind my own driving position, although the centre position is all but useless thanks to an enormous raise for the driveshaft.

Headroom is passable, but you wouldn’t want to be much taller than me. 

There are, again, tiny bottle holders in the doors, and a further two in the drop-down armrest. Rear seat passengers get dual adjustable air vents on the back of the centre console, one USB 2.0 outlet, and elastic nets on the backs of the front seats.

The boot measures 480 litres which is up there with a lot of mid-size SUVs, but because it’s a sedan, access is more limited, and it won’t accommodate as many awkwardly-shaped objects.

The Giulia we’re looking at for this review is the mid-spec Veloce, which costs $74,950 before on-road costs, sitting above the base Ti ($68,450) and below the top-spec Quadrifoglio ($153,700).

Natural rivals from Germany include the Audi A4 45 TFSI ($77,869), BMW 320i M Sport ($80,200) and Mercedes-Benz C200 ($89,900) all of which suddenly make the attractive Alfa look like a not-half-bad deal.

But then there’s always the Genesis G70 (from $63,000 in equivalent turbo 2.0L form) to bring the value equation back to reality.

Standard stuff at this grade includes 19-inch alloys, an 8.8-inch multimedia touchscreen and a 12.3-inch digital instrument cluster (new for the 2024 model year), dark contrast exterior highlights, leather seat trim with heated front seats and steering wheel, aluminium interior detailing and shift paddles with extended leather trim on the dash, updated LED headlights and DRLs, dual-zone climate, push-start ignition and keyless entry, tinted rear windows, and a 14-speaker Harman Kardon audio system.

Performance-wise, the Veloce also scores a limited-slip rear differential to match its punchy engine.

The tech feels a bit old, and the interior has a dated ambiance to it compared to the more open and digitised spaces of its rivals, but there’s something to be said for how organic the Alfa feels. More on this later.

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 Veloce might not pack a Ferrari-derived six-cylinder engine like the Quadrofoglio, but its smaller 2.0-litre four-cylinder turbocharged petrol engine hardly wants for power.

Packing 206kW/400Nm it outpunches six cylinders of old easily, and is still capable of sprinting to 100km/h in a hot-hatch baiting 5.7 seconds to a Vmax of 240km/h.

It even sounds fantastic, as it flies up the rev-range living up to every bit of the Alfa promise. Peak power arrives at 5250rpm, but peak torque hits at 2250rpm.

Smooth shifts are provided courtesy of an eight-speed traditional torque converter automatic transmission.

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.

The 2.0L turbocharged engine has an official combined cycle fuel consumption figure of just 6.1L/100km, although I saw 9.0L/100km in my time with it.

I’ll admit it was being enthusiastically driven, and treated to lots of urban commuting.

The Giulia has a 58-litre fuel tank and requires mid-shelf 95 RON premium unleaded fuel. Its approximate range on a full tank at the official consumption is 951km.

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).

Put simply: The Giulia is a celebration of Alfa Romeo. Yes. Even with a humble 2.0-litre turbocharged engine and an automatic transmission, this is a deeply emotional car. A riveting experience from behind the wheel.

Fly round corners, your eyes wide, exclaiming ‘magnifico!’ as the Giulia gracefully leans in, the rear LSD, sporty tyres, and wonderfully tight steering working together in harmony as you eke out just a smidge of tyre roar.

Laugh out loud to yourself, as you plant the accelerator, hear the muted rumble of the surprisingly angry little engine, and feel the turbocharger kick in half a second later as you power out.

‘Eccezionale!’ You’ll think, as you feel the click of the immensely satisfying metal paddle-shifters, and the transmission responds in-kind, the engine roaring up the revolutions with enthusiasm.

Sure, the Veloce grade is not as raw, or as wild, or near as fast as the top-grade Quadrofoglio, but all of the exciting spirit of  that car is still here, and at a little over half the price, too. The Veloce is an absolute delight to drive.

It has such poise, makes such a fine sound, and does it all so gracefully. This is how you make a car feel as one with the driver.

Even the ride is deeply impressive. It’s not too harsh or noisy, while gifting the chassis just the right amount of lean in the corners and allowing enough play for it to remain controlled over bumps.

Not only does it work well when you’re driving as it's clearly intended to be driven, but around town it’s quiet and refined inside, living up to the promise of a luxury sedan.

The seats and bolstering are great, the visibility isn’t too bad, and while I’ll complain about the slightly laggy software on the multimedia screen, the digital dash is responsive and the physical climate controls are welcome.

It’s not all perfect. If it were, I think it might cease to be an Alfa Romeo and start sprouting BMW badges.

For example, our test car, with less than 2000km on the odometer, had various inconsistent rattles emanating from the plastic garnish around the digital dash, and somewhere behind the back seat.

Regardless, driving this car has made me a little sad Alfa will be putting this wonderful platform behind it in pursuit of more electrified goals.

I can only hope wherever the Giulia nameplate goes next, it retains the spirit of this version.

The same safety equipment suite is standard on every Giulia variant.

Advanced active gear includes auto emergency braking, lane keep tech, blind-spot monitoring with rear cross-traffic alert, driver attention alert, and adaptive cruise control.

It also scores front and rear parking sensors, and a reversing camera with guidelines. 

The Giulia’s maximum five-star ANCAP safety rating expired at the end of last year, as it was originally rated back in 2016. The facelifted model is ‘unrated’ relative to ANCAP’s current standards.

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.

Alfa finally updated its warranty to a more industry-standard five-years and unlimited kilometres in 2022.

Service intervals occur at 12 monthly or 15,000km intervals for the 2.0-litre turbocharged variants. Pricing was not available for the model year 2024 version yet in the brand’s online calculator, but to give you an idea for the pre-facelift version, pricing came in between $345 and $1065 per visit, averaging $573 per year for the first five years of ownership. Not cheap, but not as expensive to run as you might expect.

One thing you might want to keep in mind is depreciation. Boring, I know, but even late model examples of the Giulia and Stelvio have been hit particularly hard by the depreciation stick according to residual values we searched up on Autotrader.

For reference, the Genesis G70 and BMW 3 Series have both fared much better in equivalent 2.0-litre turbo forms.
