Subaru Crosstrek vs Kia K4

What's the difference?

The Crosstrek is good to drive with great ground clearance and an excellent all-wheel drive system for light off-road adventures. I’m also a fan of the styling and features for the money. But The letdowns comes in the form of limited boot space and cabin storage, a short warranty and pricey servicing. Still, it’s great to see Subaru has updated the car's safety systems, the most important part of any car.

The new Kia K4 GT-Line has a lot to offer - an interesting design, lots of features and a pleasant driving experience. It’s not without its quirks and there are times when a more powerful engine may have improved it for me as a long-term prospect as I do some big kays every year but it ticks the boxes as a friendly urban dweller.

While SUVs tend to come in either a tall and boxy or coupe-like shape, the Crosstrek has a uniquely sleek and sporty wagon look that has stayed much the same over three generations.

Also while the Crosstrek competes with the Honda HR-V, Hyundai Kona, Mazda CX-30 and Toyota Corolla Cross the Subaru is the most off-road suitable thanks in part to its high 220mm ground clearance

As if to signal those adventurous aspirations the Crosstrek has a more rugged appearance with robust-looking plastic guards and chunky roof rails.

Inside the Crosstrek looks so much the same as most other new Subarus it's hard to work out which one you’re in. The materials are dark and soft, there is not much in the way of glitzy trimmings but there’s a high quality feeling throughout. 

Have to admit I wasn’t convinced on the design of this new sedan at first as it can look a little out of sorts from certain angles. But the more time I spend with it, the more I appreciate its sharp lines and sporty rear shaping.

The small sedan market doesn't have a lot of options now because SUVs are so popular but it's nice to see a design that stands out and the fang-like LED light design at the front and rear, as well as the 18-inch alloy wheels make the K4 look very cool.

The rear doors look sleek because the handle has been hidden in the C-pillar and the K4 is particularly striking in our test model's 'Wave Blue' ($600 RRP) paint colour.

Head inside and you'll find a cabin that looks slick with a two-tone synthetic leather upholstery that feels supple underhand and a plethora of soft touchpoints under all the bits that touch.

The black headliner creates a posh space but the sunroof helps the cabin to feel airy when you need it to.

The dashboard isn't too wide, preferring a sharply linear shape and is headlined by a massive display panel that houses dual 12.3-inch screens and a 5.0-inch climate panel.

There is still a strong presence of plastics inside but you don’t tend to focus on them.

Unlike some other new cars hitting our market, the K4 hasn’t done away with its buttons and dials - and there’s enough to satisfy those who don’t like to rely on a screen for everything. The extra traditional element of the physical gear selector adds to its charm as well. 

The Crosstrek is a small SUV but its low and sleek shape doesn’t do it any practicality favours in terms of exiting and entering or storage in the boot.

Boot capacity is 291 litres which is very small compared to its rivals which have capacities closer to 350 or 400 litres.

People space inside, however, is good, and even for a tall (189cm) person like me there’s plenty of space up front and behind my driving position.

Storage space is passable with three cupholders and thin door pockets and a decent-size console bin.

Given the Crosstrek’s adventurous intent, the cabin should be more reflective of that rugged aspiration.

The K4 feels big for the class, especially compared to its nearest rivals and that translates to a cabin that feels adult-friendly in both rows. An impressive feat for a small sedan.

Access is the only time you will have moments of 'I should have opted for an SUV'. That's because you will get in your daily squats sliding in and out of the K4 due to its 140mm ground clearance.

The rear doors also feature a wide wing that juts out from the door handle and it catches your hip almost every time you go to close the door.

The wide front seats offer lots of comfort with thick padding and long under-thigh-support. The driver's side is powered with adjustable lumbar support but the passenger seat only offers manual adjustments, which is surprising for a top-grade model. However, both front seats enjoy heat and ventilation functions.

The back bench seat offers similar comfort to the front with seat padding and length but it's not terribly wide and two adults (or child car seats) will fit best.

Amenities and storage is decent for the class with each row enjoying four drink holders and two USB-C ports. Front rowers also get a wireless charging pad and 12-volt socket.

In the front there is a large glove box that fits more than just an owner's manual, a mid-size middle console and a centre console that features retractable cupholders to open up the space if you need to. A dedicated phone cradle with small spaces on each side rounds up individual storage for the front.

In the rear there are two map pockets, a small item cubby next to the USB-C ports and a pair of directional air vents, reading lights and a fold-down armrest.

The boot space is massive for the class at 508L (that's nearing mid-size SUV territory) but the aperture is narrow and I couldn't fit my big booster seat through the opening.

The boot is quite deep as well and you may find yourself climbing into it to retrieve items that roll into the back.

The rear bench seat has a 60/40 split which can help with storage and there is a temporary spare tyre underneath the floor.

While you don't get a powered tailgate in this model, the lid isn't heavy to operate and has a proximity opening function that keeps it practical when you have your hands full.

This just means when you approach and stay near the boot with the key fob on your person the boot lid will pop open for you.

The 12.3-inch touchscreen multimedia system looks great with crisp graphics and a responsive touchscreen. The menus are in an easy-to-understand layout which you'll get accustomed to in no time. The 5.0-inch climate display sits to the right of this system and it's nice to have it on display all the time.

The 12.3-inch digital instrument cluster isn't all that customisable but it's easy to read with large text and a small menu screen that shows nav directions, trip info or a compass.

The built-in satellite navigation system is easy to get going and to cancel a route guidance, it's a one button affair which is great for when you're on the go.

The system features wired and wireless Apple CarPlay and Android Auto. The CarPlay is simple to connect to and retained a steady connection this week with feedback from my callers that my voice was clear on calls.

The new K4 sedan is offered in four grades - the base-model S which has an optional 'Safety Pack' available, the mid-spec Sport and Sport+ grades and the flagship GT-Line, which is the model on test for this review.

The GT-Line is sharply priced at $42,990, before on road costs. This positions it in the middle of its small sedan rivals, the Hyundai i30 N Line Premium ($41,500 MSRP) and the Mazda3 Astina ($43,310 MSRP).

What the K4 GT-Line has going for it over its peers is a standard specification list that features some heavy-hitting technology.

This includes dual 12.3-inch displays, a 5.0-inch climate display, built-in satellite navigation with 10-years' of map updates, wireless/wired Apple CarPlay and Android Auto and dual-zone climate control.

Charging is taken care of by two USB-C ports for each row but the front row also enjoys a 12-volt socket and fast wireless charging pad in the dedicated phone cradle.

There's also an eight-speaker Harman Kardon sound system, over-the-air updates, digital radio, AM/FM radio, Bluetooth connectivity, and a 'Sounds of Nature' soundscape for added ambience.

The Kia Connect app is also included and this allows user access to the emergency call functionality (e-Call), remote control functions for the vehicle, as well as vehicle status monitoring.

Premium equipment includes a tilt and slide sunroof with electric sunshade, two-tone synthetic leather upholstery, heated and ventilated front seats, an electric drivers seat (with two-position memory function and adjustable lumbar support) and a heated steering wheel.

For a small sedan, it comes packed with features!

The Crosstrek 2.0S uses a 2.0-litre, four-cylinder, horizontally-opposed 'boxer' petrol engine which makes 115kW and 196Nm. A continuously variable transmission (CVT) with eight 'speeds’ isn’t the most exhilarating automatic but all Subaru now use CVTs.

The boxer engine has advantageous in terms of a lower centre of mass and helps deliver better driving feel thanks to more adept handling. Boxer engines also sound better to my ears with their throaty burble.

The flagship grade is front-wheel drive and has a 1.6-litre four-cylinder, turbo-petrol engine that produces up to 142kW of power and 265Nm of torque giving this a more powerful presence than its non-turbo siblings (which only produce up to 112kW/192Nm).

However, while the power is adequate for the GT-Line there are times when the engine sounds like it's working a bit too hard.

The eight-speed torque-converter automatic transmission can also become flustered as it moves through the lower gears, especially when you’re accelerating quickly.

On the whole, the power delivery and outputs are more than enough for a city environment and the odd road trip.

The Crosstrek 2.0S's combined cycle (urban/extra-urban) fuel consumption is 7.2L/100km which aligns closely with our real-world test average of 8.7L/100km returned over mainly urban and city driving. That’s not bad, but given the price of fuel as well as the availability of EVs and excellent hybrids from other brands the Crosstrek is seriously behind the times.

Yes, yes, there is a hybrid Crosstrek, but it’s a mild-hybrid and the electric motor doesn't drive the wheels and doesn’t save much fuel. The hybrid Crosstrek has a claimed combined cycle consumption figure of 6.5L/100km, so there’s not much difference between the efficiency of the two. When you consider the price premium you need to pay it’s not worth stepping up into the hybrid.

With an official combined (urban/extra-urban) cycle fuel usage figure of 6.7L/100km and a fuel tank size of 47L, this model has a theoretical driving range of 701km. That does sit around 80 kays less than some of its rivals but it’s still sufficient for those wanting to do the odd road trip!

My on-test fuel usage has popped out at 9.2L/100km, which is based on figures achieved at the pump (32.05L) and my km travelled (348km).

I’ve done mostly urban trips this week with one longer open-road drive and overall I’m not too surprised by that figure because I’ve been pushing it hard but it could be better.

The K4 is a simple gal because Kia recommends a minimum 91 RON unleaded petrol to be used for all models.

I’ve never met a new Subaru that wasn’t good to drive, apart from that time a friend sent me his 30-year old Brumby minus brakes. But even that was fun, until it was time to stop… Anyway, in my view the Crosstrek is better than its rivals in multiple areas except one, which I’ll get to in a moment.

The Crosstrek 2.0S is comfortable to sit in and its ride and handling balance is exceptional for a vehicle in this class. Honestly, the ride quality, body control and steering outshines the HR-V, Kona, CX-30 and Corolla Cross in my view.

A big call out has to go to the Crosstrek's all-wheel drive system, which is exceptional. I have tested this vehicle in some pretty adventurous settings and the kind of terrain it can devour would frighten its rivals.  

But the one area that lets the experience down is the CVT auto. I feel this way about this type of transmission in any car and I’m not alone. CVTs provide smooth acceleration and deceleration but if you’re hoping for an engaging, sporty experience you’ll be left wanting.

That said, my wife also drove the car and thought it was perfect for city traffic. And I agree, it’s just on the motorway where you might notice the lack of oomph when overtaking.

Visibility is good and you sit quite high for a little SUV. That small size makes it easy to park and manage in the city’s tighter spaces.

As mentioned earlier, the power is adequate to move this car around on the open-road but you have to be a little aggressive on hills to keep your speed consistent.

It’s not always quick off the mark, though, and you’ll notice that when you have to cross traffic or enter a roundabout - so allow for extra car lengths. Once you get going, it’s responsive in the city.

The steering is sports-stiff and so is the suspension. This makes the handling feel nimble in turns and sure-footed when doing quick lane changes but you hear and feel every bump in the road. 

On-road comfort is okay around the city but the road noise is very loud inside the cabin and is particularly noticeable at higher speeds. You’ll have to raise your voice to chat to passengers in the back when you're on the highway.

The K4 has a small turning circle of just 10.7m and you can easily do a U-turn in spaces that others might have to do a three-pointer. This made the K4 feel friendly in small car parks and on ramps.

The direct steering makes it easy-enough to park, as does the reversing camera and front/rear parking sensors but I’m pretty disappointed that at the top grade-level, you miss out on a 360-degree camera system (tsk, tsk, Kia).

The Kia K4 has just been launched and hasn’t been tested by ANCAP yet, so is unrated but Kia is hustling to get it tested so it can join in on their strong five-star performance record. The K4 has seven airbags, including a front centre airbag.

The K4 GT-Line has all of the bells and whistles when it comes to safety equipment and includes the big-ticket items like blind-spot monitoring and collision avoidance, intelligent seatbelt warning (all seats), rear cross-traffic alert, front cross-traffic alert, lane keeping aid, lane departure alert, leading vehicle alert, emergency call functionality, side exit warning, rear occupant alert, traffic sign recognition, driver monitoring and alert, LED DRLs, dusk-sensing LED headlights, front/rear parking sensors and a reversing camera with dynamic guidelines.

The K4 GT-Line has AEB with forward collision warning, car, pedestrian, cyclist, and junction crossing detection.

The rear seat has two ISOFIX child seat mounts on the outboard positions and three top tether anchor points but two seats will fit best.

Kia has become well-known for having annoying sound alerts in their cars and while the K4 has them too - you can easily disable the most annoying one, the traffic sign recognition, by holding the steering wheel volume button in for a few seconds.

Subaru’s five year united kilometre warranty is becoming less appealing as other brands offer seven or even 10 years of coverage. 

Servicing is recommended every 12 months/15,000km and a capped schedule is pricey relative to its competitors at more than $2400 over five years or about $400 on average per service.

The brand is represented by a long-established and stable network of close to 130 dealers covering metro, rural and regional locations across every state and territory.

The K4 GT-Line is offered with Kia’s seven-year/unlimited-kilometre warranty. That’s a pretty good term for the class and there is a seven-year capped price servicing program for a flat $3877 (averaging $554 per service), which is slightly more expensive than others in the class.

Servicing intervals could get annoying if you do big kays every year as they're spaced at every 12 months or 10,000km, whichever occurs first.
