Cupra Formentor vs Mercedes-Benz E53

What's the difference?

It’s clear that Cupra has listened to feedback as this updated Formentor addresses many key criticisms of the pre-update car. Overall it makes it easier to live with and to recommend than before.

Although the VZe's updated PHEV powertrain offers double the amount of electric range, the V forms as a sweet spot of the line-up as it offers all the power and equipment you'd ever need. It's hard to look past the top-spec VZx though as power is a drug.

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.

As with many updates, the Formentor has received some mild changes to the exterior design. A lot of it centres around the new, shark-like front end which brings it in line with the Leon, Terramar and Tavascan.

I’ve always been a fan of the Formentor’s slightly raised but still hunkered-down hot hatch-look. The body lines and wheel-arch flares also lean into the dynamic aesthetic.

The VZx trim looks particularly sexy with its 19-inch black and copper forged alloy wheels and the black quad exhaust tips.

I cannot wait for the VZ5 to arrive as it’s set to receive even larger 20-inch alloy wheels and more prominent quad exhaust tips that are stacked and finished in copper.

Inside it’s fairly similar to before but a highlight is the larger 12.9-inch touchscreen multimedia system. It suits the dashboard nicely while not looking too big.

There are still the pronounced, hexagonal air vents up front, plus the ambient lighting strip that wraps all the way from door to door. It’s a cool look.

If you’re keen on the ultra-sporty look, you can option Sabelt front bucket seats with carbon-fibre backs as part of the Extreme package in the VZe and VZx. It’s worth noting that this removes the front centre airbag though.

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. 

The standard seats in the Formentor have a sporty design but are still supportive and comfortable. The driver’s seat offers electric adjustment and memory as standard, while both front seats are heated.

The optional Sabelt front bucket seats hug you tighter which is nice if you plan to driving on twisting roads. It’s cool that they retain the electric adjustment and heating as this is rare in ultra-sporty seats.

Looking ahead, this steering wheel is one of my favourites on offer from any brand currently. The rim isn’t too thick or thin, plus there are plenty of physical buttons and dials. It makes it a joy to interact with.

This update has made the steering wheel-mounted engine start-stop and drive mode buttons standard across the line-up. It makes the less sporty trims feel a touch more special.

The 10.25-inch digital instrument cluster is still standard across the line-up and offers plenty of configurable options. You can set it up exactly how you'd like.

Moving across, there’s the aforementioned 12.9-inch touchscreen multimedia system. It operates on updated software which makes navigating key menus much easier.

Some key climate control functions remain at the bottom of the touchscreen which is a little easier to interact with on the move. Ideally a physical button cluster would be better but you can’t have everything.

Another key change with this update is the touch sliders under the touchscreen are finally illuminated, allowing you to see what you’re pressing at night. This should have been standard since launch.

Storage up front is adequate for a car of this size. There’s a wireless charger that’s not ventilated, two USB-C ports, a strange cupholder set-up with essentially 1.5 cupholders, a centre console box with a lid that ratchets, as well as a glovebox on the passenger side.

It’s clear the focus of the Formentor’s cabin is up front but space in the second row is a better than you’d think. At a leggy 182cm I have decent leg and headroom behind my own driving position, but toeroom is particularly good, allowing you to slide your feet comfortably under the seat ahead.

What isn’t so nice is the front seats are rather bulky, particularly the optional Sabelt bucket seats. They block your view ahead, requiring you to either lean over or look out the side window.

Second-row amenities include a third zone of climate control with air vents on the back of the centre console, as well as two USB-C ports and a fold-down armrest with cupholders.

There are ISOFIX points on the two outboard seats, as well as top-tether child seat anchorages across all three rear seats.

All versions of the Formentor now receive a hands-free power tailgate which is handy if you’ve got your hands full. It opens and closes with a kick under the rear bumper.

Boot space depends on the trim level. The S offers 450L, the V and VZx have 420L and the VZe only offers 345L with the rear seats upright. The latter is poor due to the placement of the high-voltage battery.

With the rear seats folded there’s between 1300-1400L of boot space, depending on the trim level.

Boot-related amenities include a light and some hooks. It’s great to see a space-saver spare wheel as standard across all variants besides the VZe. This is once again due to the high-voltage battery.

You even retain a space-saver spare wheel if you opt for the Extreme package in the VZx, though it has a note stating you cannot put it on the front as it physically won’t fit over the larger front brakes.

If you get a puncture on the front, you need to swap a wheel from the rear onto the front, then put the space-saver spare on the rear. You should technically be doing this anyway as space-saver spare wheels aren’t meant to go on the front in cars that are primarily front-wheel drive, like the Formentor.

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.

At launch all versions of the updated Formentor feature turbocharged four-cylinder petrol engines of varying sizes and power outputs, as well as dual-clutch automatic transmissions.

This will change when the flagship VZ5 with its turbocharged five-cylinder from the Audi RS3 arrives later this year.

The entry-level Formentor S is powered by a 1.5-litre turbo four-cylinder with 48V mild-hybrid assistance and total system outputs of 110kW and 250Nm. It has a seven-speed dual-clutch and is front-wheel drive.

The Formentor V gets a 2.0-litre turbo four-cylinder that produces 150kW and 320Nm. This is 10kW more than before. It has a seven-speed dual-clutch and is all-wheel drive.

The Formentor VZe has a 1.5-litre turbo four-cylinder and an electric motor with total system outputs of 200kW and 400Nm. This is 20kW more than before. It has a six-speed dual-clutch and is front-wheel drive.

Lastly the Fomentor VZx has a 2.0-litre turbo four-cylinder that produces 245kW and 420Nm. This is 17kW and 20Nm more than before. It has a seven-speed dual-clutch and is all-wheel drive.

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.

One of the biggest changes with this update is the Formentor VZe’s PHEV system.

It now features a larger 20kWh lithium-ion battery pack that allows up to 114km of electric driving, according to WLTP testing. This is roughly double the amount of the pre-update car.

This battery now also offers DC fast charging at rates up to 50kW, plus the AC charging rate has increased to 11kW (it was previously 3.6kW).

Cupra claims the updated Formentor VZe consumes an average of 1.7L/100km, which is 0.2L/100km better than the pre-update car. However, this will depend greatly on whether you charge the battery.

Elsewhere in the line-up, the entry-level Formentor S with its mild-hybrid system has a claimed combined fuel consumption of 5.5L/100km.

The Formentor V is claimed to consume 7.0L/100km and the VZx is claimed to consume 8.3L/100km (8.5L/100km with the Extreme package).

The Formentor V and VZx have 55L fuel tanks, the S has a 50L fuel tank and the VZe has a 40L fuel tank. All require a minimum of 95 RON premium unleaded petrol, while the VZx requires a minimum of 98 RON premium unleaded petrol.

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.

The entry-level Formentor S’s mild-hybrid powertrain has modest outputs of 110kW and 250Nm and around town there’s enough juice on tap.

However, once you get out on the open road the ceiling of this powertrain reveals itself quickly, requiring it to dive back through the gears ruthlessly in order to keep up the pace. This is less of a problem if you’ve already got the car in a sporty drive mode.

The small electric motor that’s fed by the 48V mild-hybrid battery provides a minor boost off the mark, but it mainly smooths out the low-speed hesitancy from the dual-clutch automatic.

Moving up, the Formentor V’s turbo-petrol engine firms as the sweet spot of the line-up if you’re not after the ballistic craziness of the VZx. With the extra power and torque it’s a little less stressed than the S, plus you have the security of all-wheel grip.

The Formentor VZe’s PHEV powertrain is noticeably different from behind the wheel. Extra electric range aside, the electric motor is still packaged within the dual-clutch transmission although unlike the pre-update model, you can no longer feel the car shifting between gears.

There’s plenty of power available and depending on the battery charge the car can turn the engine off and on even at highway speeds. You can’t actually feel it happening, you only see the tacho rise and fall.

Lastly, the VZx is a missile. It feels incredibly unstressed in everyday driving and with a subtle flex of the right foot it gets moving with haste.

Like some Volkswagen Group products, the Formentor can hold a higher gear in its standard drive mode, taking a beat to kick down a gear if required. Thankfully peak torque is available down low in the rev range across the line-up.

Compared to the pre-update model, the VZx now gains a trick torque-splitting rear differential and a ‘Drift’ mode. We had the chance to sample the old and new cars back-to-back on a wet skid pan and the difference is night and day.

The pre-update model has terminal understeer no matter how much you coax it, however the updated Formentor VZx is incredibly tail-happy. You can do smile-inducing four-wheel drifts with ease, plus it will stop itself from going over the edge and spinning out.

Obviously this is something that you can only use on private roads and it isn’t something that you’d use everyday. It’s a cool novelty feature to try if you get the chance.

As standard there is progressive steering across the line-up which ramps up the resistance the more you turn the wheel. In practice this makes the Formentor a fun and agile car to drive, even around town.

A subtle change with this update is the entry-level Formentor S and V now receive a standard passive damper set-up, whereas the VZe and VZx have adaptive dampers. The latter was previously standard across the line-up and it allows you to configure the ride from comfort soft to sporty firm.

While it’s nice to have the configurability, the ride on the standard passive dampers is still beautifully compliant. It’s a little more comfort-oriented than I’d expect from a Cupra but I don’t hate this in the less-powerful variants.

In terms of noise, vibration and harshness (NVH), this is the Formentor’s downfall. Like many European cars, there is a lot of road and tyre noise on the open road, especially on coarse-chip roads.

Surprisingly some of the cars on the launch were already starting to develop random rattles around the cabin. This isn’t great as all the cars were brand new with around 1000km on the odometer.

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.

The Formentor, like all other Cupras, is covered by a five-year, unlimited-kilometre warranty, which is a little lacklustre for a mainstream brand now as many have moved to conditional eight or 10-year terms.

Logbook servicing is required every 12 months or 15,000km, whichever comes first.

There are three- and five-year pre-paid service packages available that are priced at $1090 and $2190, respectively. In the latter case, this means each service averages out to almost $440 which is fairly average for a European car.

Cupra currently has 40 dealers and 28 service centres in Australia. Many of these are located around major cities.

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.
