Kia K4 vs Mercedes-Benz CLA200

What's the difference?

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.

The Mercedes-Benz CLA 200 is sleek, well-equipped, and beautifully engineered. That said, it’s pricey. You can get a car that’s 80 percent as good for 50 per cent of the price. But getting that extra 20 percent in terms of refinement, dynamic ability and design sophistication is what you’re paying for. If you’ve got the extra dough, top dollar buys you a spot on the top shelf.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

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. 

While the way a car looks is a subjective call, and as always, your thoughts are welcome in the comments below, I’m putting it out there… this is a beautiful machine. And Gordon Wagener’s not pulling any punches, either. He thinks it has the potential to become, “a modern design icon.”

The long bonnet, cab-rear, wide-track proportions sit within a slightly larger footprint. The new CLA is marginally longer, wider, lower overall, and has a lengthier wheelbase than the model it replaces. And the car’s intricate mix of gently curved surfaces and hard lines is expertly managed, with a standard AMG body kit, complete with 18-inch rims, adding just a hint of macho intent.

The angle of the shoulder runs from this character line, virtually unchanged up to the roof, and the inward slope of the side glass (car designers call it tumblehome) is quite pronounced. And the sweeping curve at the top of the front guards is defined by hard strakes on the outer edges of the bonnet.

The rear view is arguably the CLA’s most appealing angle with the intersection of the sloping turret, boot, and rear guards neatly resolved.

It’s super slick aerodynamically, as well, boasting a Cd of 0.23, running a close second to it’s A-Class sedan sibling (0.22) which Merc claims as the world’s most aero-efficient series production four-door.

But what about the inside? Well, the biggest visual feature is the customisable MBUX media and data interface, expressed dramatically through a pair of 10.25-inch widescreens.

The info available and number of configurations offered is mind-blowing. It’s very 2019 and spot-on target for the digital generation.

Piano black surfaces around the dash and console lift the tone (but pick up the fingerprints) while the signature turbine-style vents add another flash of visual interest without compromising function.

Other highlights include front seats with racy one-piece backs (reflected on the top of the outer rear seats, as well), frameless doors enhancing the coupe feel, and neatly detailed stitching around the dash and doors.

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.

Despite a two mm drop in overall height, the CLA’s front headroom has been extended by 17mm, and there’s lots of room up front, with storage running to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), an overhead sunglass holder, decent door pockets with room for bottles and a medium-size glove box.

There’s also a mat for wireless device charging at the front of the centre console, complete with another USB input (just in case).

But what does that sexy, sloping roofline do for space in the rear?

Sitting behind the driver's seat set to my (183cm) position, there’s adequate legroom, but despite Merc claiming an extra 3.0mm of headroom, my noggin made firm contact with the headliner.

It’s worth remembering this is a coupe-style four-door, with the packaging compromises a swoopy roof brings. You could call it a ‘2+3’, with a couple of doors added to make access to the back seats easier.

A centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, map pockets on the front seatbacks, and adjustable ventilation outlets set into the back of the front centre console are a welcome inclusion.

There are three belted positions across the rear, but the adults using them for anything other than short journeys will have to be good friends and flexible. Kids will be fine.

Boot volume is a healthy 460 litres (VDA), which is down 10 litres on the first-gen car, but the aperture has been widened by no less than 262mm, and a 40/20/40 split-folding rear seat opens up extra space. There are tie-down hooks, a 12-volt outlet and elasticised storage pockets either side of the load space to further enhance useability, plus a cargo net is included.

No news on towing capacity at this stage, and don’t bother looking for a spare, the tyres are run flats.

In Australia the CLA 200 weighs in at $59,500, before on-road costs, which is plenty, but the all-wheel drive CLA 250 ($68,800) will join it early in 2020, so the range will line up against the likes of BMW’s 4 Series Gran Coupe, even the Audi A5 Sportback.

The Mercedes-AMG CLA 35 ($83,400) arrives before the of 2019, with the full-fat CLA 45 S scheduled for Q1 2020 (estimated circa $95,000).

For that $60K price tag the CLA 200’s standard features list includes, dual-zone climate control air, sports seats, ambient (interior) lighting, ‘Artico’ and ‘Dinamica’ trim (faux leather and suede, respectively), the twin 10.25-inch digital media and instrument screens (running the ‘MBUX’ interface), an AMG styling pack (including 18-inch alloy wheels), active cruise control, auto headlights, keyless entry and start, LED headlights, DRLs and tail-lights, a leather multi-function, flat-bottom sports steering wheel, sat nav, park assist (including a reversing camera), rain-sensing wipers, wireless phone charging, ‘Hey Mercedes’ voice control, and nine-speaker audio including digital radio as well as Apple CarPlay and Android Auto.

All CLAs can also be hooked up (via a smartphone app) to the ‘Mercedes me Connect’ remote connectivity system, allowing access to locking/unlocking the doors, tracking and locating the vehicle, retrieving maintenance and service information, and more.

For the record, our test example was loaded with five option packages, adding no less than $13,630 to the price tag for a total of $73,130. Specifically, the ‘AMG Exclusive Package’ ($3190) – Heated and cooled front seats, ‘Lugano’ two-tone leather upholstery (with contrast top-stitching), adaptive damping, and ‘Energising Comfort Control’, the ‘Communications Package’ ($2490) - Head-up display and  Burmester 590W, 12-speaker ‘surround sound’ audio, ‘Driver Assistance Package’ ($1790) – ‘Active Distance Assist’ (including ‘Cross-Traffic Assist’), ‘Driving Assistance package Plus’, ‘Lane Change Assist’, ‘Extended automatic Re-start’ (in traffic), and ‘Route Based Speed Adaptation’, and ‘Seat Comfort Package’ ($1290) - Electrically adjustable front seats, memory function for driver’s seat, exterior mirrors and head-up display (if fitted), heated front seats, and passenger mirror with reverse parking position, and ‘Vision Package’ ($2490) – ‘Adaptive Highbeam Assist PLUS’, ‘Multibeam’ LED headlights, panoramic electric sunroof, ‘Parking package HIGH’ (featuring 360-degree camera).

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 CLA 200 is powered by Merc’s 1.3-litre (M 282), direct-injection four-cylinder turbo-petrol engine driving the front wheels through a seven-speed dual-clutch auto transmission (with paddle shifters on the wheel).

It’s the product of a joint development with Renault, and outputs are 120kW at 5500rpm and 250Nm at 1620rpm, which is pretty impressive for such a small capacity unit.

The single turbo features an electronically controlled wastegate and flexible charge pressure control to optimise boost across the entire rev range (rev ceiling is 6300rpm), with an equal focus on power, step-off throttle response and fuel efficiency.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.7L/100km, the CLA emitting 130g/km of CO2 in the process.

At just over 1.4 tonnes it’s fairly hefty for its size, but at partial load between 1250-3800rpm two of the engine’s four cylinders shut down to improve economy. ‘ECO’ mode dampens performance in the name of improved economy, plus stop-start is standard.

And over roughly 200km of freeway, city and suburban running we saw an average of 7.5L/100km courtesy of the on-board read-out.

Minimum fuel requirement is 95 RON premium unleaded, and you’ll need 43 litres of it to fill the tank, which at our real-world average delivers a range of approximately 575km.

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).

So, despite the engine’s small capacity the addition of a turbo means peak torque (250Nm) arrives at just 1620rpm. Power delivery is linear and mid-range acceleration is healthy. Claimed 0-100km/h acceleration is 8.2sec, which is neither sluggish nor particularly fast, but performance is more than adequate around town and on the highway.

The seven-speed dual-clutch auto shifts smoothly, but not particularly rapidly, although a switch to manual mode and use of the wheel-mounted paddles means you can be more selective about which ratio you’re in and for how long.

Standard suspension set-up is strut front, multi-link rear, with many of the components made from aluminium to reduce unsprung weight, and the CLA feels nimble through twisting backroad bends.

Our test car was optioned with the AMG Exclusive Package, which includes adaptive dampers. And no surprise ‘Sport’ mode is severe, and the fillings in your teeth (unless you’re one of those strange people that don’t have any) will be in danger of rattling loose over anything other than a billiard table smooth surface.

By contrast, ‘Comfort’ lives up to its name with a supremely compliant ride without any sacrifice in terms of balance and (taut) body control. The standard 18-inch rims, shod with 225/45 rubber, don’t put a disenable dent in proceedings, either.

The electro-mechanical steering points accurately and delivers a good connection with what’s happening at the front wheels. Assistance is subtle.

Brakes are vented discs up front, with solid rotors at the rear. Purely in the interests of a full and well-rounded review we enthusiastically pushed through some lengthy B-road sections, and the pedal remained firm and consistent.

In short the CLA is a refined city coupe that doubles as a comfortable touring car.

It’s hard to fault Mercedes-Benz when it comes to safety, and the new CLA is loaded with standard active and passive tech.

Active safety tech includes ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), 'Active Brake Assist' (Merc-speak for AEB), 'Adaptive Brake', 'Attention Assist', 'Blind Spot Assist' (with exit warning assistant), 'Cross-wind Assist', 'Lane Keep Assist', a tyre pressure warning system, a reversing camera plus ‘Parking Distance Control’ (front and rear), 'Traffic Sign Assist', a wet weather brake drying function, and ‘Active High Beam Control’.

If all that fails to prevent an impact you'll be protected by the 'Pre-Safe' accident anticipatory system, plus nine airbags (front, pelvis and window for driver and front passenger, side airbags for rear seat occupants and a driver's knee bag), and the 'Active Bonnet' automatically tilts to minimise pedestrian injuries.

There’s also an impact-sensing auto door unlock system, an auto emergency call function and crash responsive emergency lighting, plus a first-aid kit, warning triangle and (five) hi-vis vests in the boot are thoughtful additions.

The A-Class (which encompasses the CLA) was awarded a maximum five ANCAP stars in 2018, and for smaller occupants there are three child restraint/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer positions.

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.

The Mercedes-Benz range is covered by a three year/unlimited km warranty, which, like Audi and BMW continues to lag behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.

On the upside, Mercedes-Benz ‘Road Care’ roadside assistance is included in the deal for three years.

Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.

For the CLA, pre-payment delivers a $500 saving, with the first three services set at a total of $2050, compared to $2550 PAYG. Fourth and fifth services are also available for pre-purchase.
