Alfa Romeo Junior vs Mercedes-Benz E-Class

What's the difference?

Our day with the Junior Ibrida MH left us wanting more.

Striking design, an inviting cabin, rorty performance and immersive dynamics are what people want and expect from an Alfa Romeo, and its smallest SUV does not let the side down.

That the mild hybrid also delivers (on paper at least) noteworthy economy, in a well-made, generously equipped and (anticipated) keenly-priced package is nothing short of a blinder.

The Junior Ibrida MH might be the most competitive and compelling Alfa Romeo for mainstream Australia… ever!

We cannot wait to confirm this on local roads. Roll on September.

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

Sharing much with other small crossovers in the Stellantis fold, including the second-generation Peugeot 2008 and Opel/Vauxhall Mokka, as well as the Jeep Avenger and Fiat 600 (that share the same production line in Poland), the Junior sits on the lightweight 'STLA Small' platform.

Checking in at 4.17 metres long, 1.78m wide and 1.5m high, the Junior (though only after a post-unveiling name change from Milano due to that illegally inferring it is built in Italy) was engineered by the same team behind the transcendental Giulia QV, which is a BMW M3 for the heart and soul.

Dimensionally, the Junior lives up to its badge, and is really replacing two Alfas – the Toyota Corolla-sized Giulietta (from 2010) and more-belatedly the Mini Cooper-chasing Mito supermini. As both competed in rapidly contracting classes, going a light SUV instead seems sensible.

And you know what? This looks and feels correct for the brand.

Alfa’s nose treatments have long been provocative and so is the Junior’s. Two interpretations of classic grille themes are available – the cursive ‘Alfa Romeo’ script evocative of pre-war racers or a bold reimagining of the red-cross/snake-and-child logo that is associated with the city of Milan.

More conventional are the neat proportions and Mazda CX-3-esque silhouette, which are spot-on for its intended SUV-seeking clientele. And still obviously on-brand, even if the boomerang tail-light treatment is more Maserati 3200. A lovely wink to the past is the Alfa 156-style pillar-mounted door handles.

And credit where it is due. The Junior looks nothing like its 2008, Avenger, Mokka or Fiat Seicento corporate cousins. Inside or out!

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

Forget every tired old cliché about Italian-car packaging and quality. Though a tad smaller inside than many small SUVs, the Junior is far from flawed.

Stepping inside, you’re greeted by a cossetting and supportive set of front seats, facing a smartly designed and executed dash that ably melds brand heritage with modernity.

The former is found in the deeply-hooded double-binnacle digital instrumentation (echoes of the company’s 1300 Junior of the ‘60s) and circular outboard vents, while the driver-angled 10.25-inch touchscreen is a nice contemporary touch. No issues with its layout or operation, either. It’s fast and logical.

The point is, with sound build quality and pleasing little details that elevate the experience, this is a classy cabin execution, juxtaposed with all the practical stuff.

That is, an excellent driving position, handsome multi-configurable instrumentation, easy reach of most controls, physical buttons for the (effective) climate system, sufficient storage including cupholders, handy USB outlets, wireless CarPlay/Android Auto connectivity… that sort of thing.

Complaints? The touchscreen is set a bit too low, meaning a glance down is required instead of eyes up on the road. In the black-trimmed test car there may be a sense of claustrophobia for some. And vision out is quite restricted as a result of the swoopy styling and slim side glass areas.

The Junior is a city-friendly crossover with more than enough space up front, but a fairly cramped rear-seat area, as its diminutive 2557mm wheelbase suggests. Most adults may need the front-seat occupants to slide forward a tad, and the centre position won’t be joyous for anybody. But at least they sit low so headroom isn’t a problem and on quite comfy cushions to boot.

As with most small SUVs, rear air vents aren’t fitted, but there are cupholders and USB ports, in line with every other small SUV out there.

And at least the Ibrida has a sizeable luggage capacity for one so small, measuring in from 414 litres to a hungry 1280L.

Of course, the lack of a spare wheel helps, but then again, this is a hybrid with extra electrification compared to a petrol-only alternative, so that’s pretty smart packaging going on right there.

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

Priced at $199,900, before on-road costs, the Mercedes-AMG E53 Hybrid 4Matic+ lines up against an interesting mix of internal combustion, hybrid and pure-EV contenders, the most closely aligned on spec and price being the BMW M4 M Competition xDrive ($201,300), Lexus LS500h F Sport ($199,250) and Porsche Taycan 4 Cross Turismo ($197,400).

And as you’d expect for a performance sedan on the cusp of $200K the standard equipment list is long. Aside from the performance and safety tech we’ll get to shortly, the E53 features four-zone automatic climate control, 17-speaker Burmester surround sound audio (including digital radio), Nappa leather trim (including the steering wheel) and the ‘MBUX Superscreen’ display consisting of three screens - 14.4-inch central media, 12.3-inch instrument/info for the driver and 12.3-inch for the front passenger.

You can also tick off the box on Android Auto, Apple CarPlay and Bluetooth connectivity, plus the power front seats (with memory) are heated.

There’s also a head-up display, panoramic sliding sunroof, ambient lighting, keyless entry and start, built-in nav, a 360-degree virtual top-down camera view, LED exterior lighting and 20-inch alloy rims. 

There’s more, but you get the idea. This car is loaded with included features that help it match or better its diverse competitive set.

There are four optional AMG packages available - The ‘Night Package’ ($3000) which includes aero-influenced body elements, special rims and more. The ‘Carbon Fibre Package’ ($6000), featuring a range of carbon bits including the exterior mirror caps, bootlid spoiler and interior pieces like the centre console and steering wheel. A ‘Performance Seat Package’ ($5000), which unsurprisingly focuses on racier front seats with integrated headrests. And the ‘Energizing Package Plus’ ($5300) adds ‘multicontour’ front seats that are heated (as are the centre console lid and door armrests) and individual fragrance for the interior, as well as ionisation of the cabin air.

Under the Ibrida MH’s stubby bonnet is Stellantis’ evergreen 1.2-litre three-cylinder petrol engine, delivering 100kW of power and 230Nm of torque. It features a variable-geometry turbo and Miller Cycle combustion process, to maximise efficiency.

Though there is also a Junior Ibrida Q4 all-wheel drive option that adds a second, rear-mounted electric motor available elsewhere, for now in Australia, it’s only the front wheels that are driven, via a 21kW electric motor built into a six-speed dual-clutch transmission and 48-volt/0.89kWh lithium-ion battery pack.

The electric-motor/MH system provides extra torque during acceleration to help boost speed and save fuel simultaneously, and there’s limited round-town electric-only low-speed driving available, or engine-off coasting when off-throttle at speed.

With a credible kerb weight of just 1305kg, the Ibrida clocks in with a power-to-weight ratio of a sparkling 76.6kW/tonne, resulting in an 8.9 second 0-100km/h sprint-time and a top speed of 206km/h.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

Unlike many regular mild hybrids, the self-charging Ibrida MH allows for brief pure-EV driving that Stellantis claims makes 50 per cent of emissions-free city-commuting possible in certain circumstances. Okay, we’ll need to experience that in Australia for confirmation.

The Alfa’s MH set-up aids a WLTP-rated fuel-consumption average of 4.9L/100km, for a carbon-dioxide emissions rating of 110 grams/km.

Using those figures as a guide, an average of about 815km between (premium-unleaded petrol) refills of the 40L tank is possible.

Our test car’s trip computer displayed an average of under 7.0L/100km, with mostly motorway driving near the maximum speed limit.

The full-hybrid Lexus LBX, by the way, averages 3.8L/100km and around 100g/km.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

In a word, superb.

This isn’t always a given for an Alfa Romeo, as too many models in the past have suffered for being based on mundane machinery following Fiat’s takeover in the latter 1980s.

Today’s exceptions are the brilliant Giulia and Stelvio, and to this list we can add the Junior Ibrida MH. It feels closely-related to these, despite using so many parts shared with other, different Stellantis models.

As we touched on earlier, the 100kW/230Nm Ibrida enjoys a healthy power-to-weight ratio, which translates to strong off-the-line acceleration and pleasingly eager throttle response once on the move.

The electric motor seems to do a great job topping up power and torque, so – during our 200km-odd drive through rural Spain – we didn’t experience hesitation or lag associated with small-capacity turbo engines and dual-clutch transmissions. This felt spirited yet smooth all the way.

And this was in the 'Normal' drive setting. In 'Dynamic' mode, which proved to be our favourite, the Junior Ibrida MH’s performance is sparkling.

That Alfa seems to have given the exhaust a bit of a spicy note is a nice nod to the brand’s sports-car heritage, but even more so is the light yet precise steering that is perfectly weighted. The driver feels connected to the front wheels – this is a hybrid, remember – and the chassis seems in-tune with what the enthusiast wants.

Suspension is via the usual MacPherson-style struts up front and a space-saving torsion beam rear end, though the Q4 Ibrida swaps the latter out for a multi-link arrangement.

At all times there were three people on board and each with luggage, but the all-too-few times we managed to slice through a corner or race up a ragged rural road, the Junior’s handling and road-holding seemed exemplary for a small SUV.

We were also impressed with the ride quality, but the chosen Spanish route featured beautifully-maintained roads, so we’ll need to confirm whether the sporty chassis tune interferes with suspension comfort on Aussie roads. Likewise, the quiet cabin experience at speed may differ from our isolated Euro experiences.

We can confirm, however, that the ADAS tech is helpful and nuanced, offering subtle intervention in a way that felt seamless after weeks of wrestling with recalcitrant Chinese SUVs back home.

As such, it is clear the Junior Ibrida MH’s basic dynamic set-up is sound, providing pleasure and control as well as stability and reassurance. This behaves like a sophisticated and very grown-up premium SUV should.

We’re very impressed.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

The Mercedes-AMG E53 Hybrid 4Matic+ hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it comes up short in terms of crash-avoidance and passive safety tech.

It features a comprehensive suite of ‘Advanced Driver Assistance Systems’ (ADAS) features including ‘Active Brake Assist’ (Merc-speak for AEB), adaptive cruise control, blind-spot monitoring, lane-change and lane-keeping assist, front and rear cross-traffic alert, traffic sign recognition, driver attention monitoring, adaptive high-beam, ‘Park Assist’ (including front and rear parking sensors) and tyre pressure monitoring.

And if an impact is unavoidable the airbag count runs to 11 - dual front, front and rear side, full-length side curtains, driver and front passenger knee and a front centre bag.

As the name implies, ‘Auto Emergency Call’ will contact emergency services after a collision and there’s even the obligatory Mercedes first aid kit and high-vis vests. 

There are three top tethers for child seats or baby capsules across the rear seat with ISOFIX anchors on the two outer rear positions.

Alfa Romeo offers the premium-manufacturer standard of five years with unlimited kilometres. Whether this continues unchanged when the Junior range arrives during the third quarter of 2025 is not yet known.

All other information, including service intervals, capped-price servicing costs and road-side assistance availability will be revealed closer to the Australian launch.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.
