Kia Seltos vs Mercedes-Benz E53

What's the difference?

Kia’s updated Seltos is more expensive than the previous version but it's better as well.

The entry grade no longer has hubcaps and gets alloy wheels, all grades have directional air vents in the second row, the jerky dual-clutch auto is gone and an excellent regular eight-speed auto has arrived, plus there’s more safety tech and modern displays screens.

What hasn’t changed is the Seltos’s size. It’s a big, small SUV, that’s easy to park in tight spaces but roomy inside even for tall, awkward humans like me. 

The sweet spot in the range is the Sport+ with the 1.6-litre engine, if only it had the LED headlights that only come on the GT-Line.

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.

This updated Seltos has had a few styling tweaks, too. The grille is taller and  there’s a new headlight design which on the GT-Line is stunning with its LED running lights.

The rear of the Seltos has been restyled as well, with a new tail-light design and again on the GT-Line there’s an LED strip which runs between them.

The Seltos is pretty big for a small SUV. At 4.4m long it’s bigger than a Hyundai Kona and a Honda HR-V and about the same size as a Nissan Qashqai and Corolla Cross.

What’s good about that is you’re getting more space inside with a package that’s still smallish on the outside.

If you think the Seltos’ look is familiar, then I agree. The Honda HR-V and Haval Jolion have very similar tail-light designs and the profile follows many of the same styling cues of the Toyota Corolla Cross.

To my eyes, though, I think the Seltos is the more refined looking of its peers with a more modern and interesting interior.

Speaking of which, keep in mind that the top-of-the-range GT-Line’s cabin is far more fancy than the interior of the entry grade S. The GT-line’s large double digital displays are impressive and the buttons around the shifter for seat heating and ventilation are replaced with blank plastic panels in the S. 

Hard plastic armrests were another of my gripes about the previous entry grade Seltos, too.

Still all cabins have a premium look even if the feel isn’t luxurious throughout on all grades. 

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. 

Some small SUVs are seriously small, which might be fine for some, but if you’re hoping to also have enough space for passengers in the back seats, and a boot which can carry plenty of luggage then the Seltos is a good choice.

Even at 191cm tall I had more than enough room to sit behind my driving position with good headroom back there, too.

Cabin storage is also good with door pockets front and rear, and a deep centre console box. As for cupholders there are two up front on all grades, while the Sport+ and GT-Line get two more in the second row fold-down armrest.

Boot capacity depends on if you’ve requested a full-sized spare wheel or the space-saver spare. With the space-saver you’ll have more room at 469 litres, while the full-sized wheel under the boot floor will leave you with 433 litres. That’s still decent for the class.

The new Seltos has directional air vents for back seat passengers which is a win (motoring journalists had been complaining about the lack of them for years) and there are also two USB ports (Type-C) for the second row along with another two for those in the front, plus a 12V outlet.

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.

The Seltos range has two engines to choose from: a 2.0-litre four-cylinder petrol engine making 110kW/180Nm and a 1.6-litre turbo-petrol engine producing even more grunt at 146kW/265Nm.

The 2.0-litre engine comes with a CVT which is a type of automatic transmission and the 1.6-litre engine has an eight-speed auto.

CVT stands for Continuously Variable Transmission and some people (me included) find the droning they cause the engine to make to be annoying. They also come with a feeling of less acceleration. 

The good news is the eight-speed auto that comes with the 1.6-litre is a great transmission with smooth shifts and a sporty nature that matches the punchy engine. 

This eight-speed auto is welcome because it also replaces the jerky dual-clutch transmission that had been paired with the 1.6-litre engine in the previous Seltos.   

All-wheel drive is only available with the 1.6-litre engine while front-wheel drive comes solely with the 2.0-litre.

So, if you’re after great acceleration and better traction then the 1.6-litre is the way to go. If you’re not after a sporty driving experience then the 2.0-litre engine will suit you, and it costs less.

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.

The smaller engine actually uses more fuel, but not a great deal more. Kia says the 1.6-litre engine with all-wheel drive uses 7.4L/100km after a combination of open and urban roads. The 2.0-litre engine according to Kia will use half a litre less at 6.9L/100km.  

Both engines only need 'standard' 91 RON petrol, too - that’s the cheap one.

Where is the hybrid variant? Good question. The answer is, there isn’t one. And neither is one coming, I’ve asked. That’s disappointing considering the Corolla Cross comes with a hybrid version of each grade in its line-up.

It’s for this reason the Seltos range scores a lower mark for fuel efficiency.

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 Kia Seltos has two personalities. The laid back Seltos with a 2.0-litre engine and the enthusiastic sporty Seltos with the 1.6-litre engine.

Regardless of which Seltos you pick, the ride is comfortable, the handling is good, and the steering is excellent. 

Kia says it's worked to make the Seltos’s cabin more insulated from road noise, but having driven it on country roads for hours I think it could do with more sound dampening.

If you’re considering the Sport+ grade and are not sure if the $3500 premium for the 1.6-litre engine is worth it, my answer would be absolutely, if you can afford it.

That 1.6-litre turbo petrol is a great engine and the new eight-speed transmission is excellent. Even as a daily driver I think anybody would enjoy driving this version of the Seltos more, and for those who like sporty driving then it’s definitely the powerplant for you.

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 Seltos is covered by Kia’s seven-year, unlimited-kilometre warranty. 

Servicing differs between the two engines.

A Seltos with a 1.6-litre engine needs to be serviced every 12 months or 10,000km and over seven years the average service cost comes to $497 per year.

A Seltos with the 2.0-litre engine needs to be serviced every 12 months or 15,000km and over seven years the average service costs comes to $434 per year.

Capped price servicing is good, but the prices can get higher than $600 for some visits.

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.
