Kia K4 vs Mercedes-Benz C220

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.

This may well be just an update to the C-Class, but the changes made are significant in terms of technology and performance, and you’re paying hardly any extra money for it. A good all-rounder for dynamics, features, refinement and value.

The sweet spot in the range has to be the C 300. It’s less than $10K more than the entry grade C200, but gets a powerful 2.0-litre engine, leather seats, the extra advanced safety equipment, tinted windows and convenience features such as a power tailgate (on the wagon) and proximity unlocking.

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. 

Now, to spot the difference between the new and the old C-Class from the outside just look at the headlights – the shape of the fitting is the same, but the new standard headlights on the C 200, C 220 d and C 300 have an LED set-up which looks like teeth, while the optional units (standard on the C 43 and C 63 S) are also LED but with a tall staggered design. Tail-lights also keep the same shape but with a different LED pattern, too.

The front and rear bumpers have also been restyled for all grades and the C 43 and C 63 S have had their grilles updated, with the former getting a new twin-louvre design, while its big brother now has chrome vertical slats reminiscent of the grille worn by the 1952 Carrera Panamericana winning 300SL.

The AMG Line Exterior package is standard on the Coupe and Cabriolet, but if you option it on the sedan it will fit a sports body kit with AMG front spoiler and side skirts.

The C 43’s gloss black rear diffuser looks tough with the new quad exhaust and the car in wagon form wins my award for best looking of the C-Class bunch.

Cabins haven’t been overhauled but they have been updated with a 10.25-inch dash-top display for media and a 12.3-inch fully digital instrument cluster - both are standard across the range and make a big styling impact in the cockpit. Mercedes-AMG grades have their own sporty version of the virtual instrument cluster.

The layout of controls remains the same, but you can now option a new real wood veneer to the centre console with 'open-pore brown walnut' and 'open-pore black ash' being your choices.

The Artico upholstery in the C 200 looks and feels ‘plasticky’. I’d option the real leather which comes standard on the C 300.

New to the C 43 are the optional ‘Performance’ seats with integrated head restraints and standard on this grade is a new leather AMG steering wheel. Other cool cabin features are the stainless-steel pedals, the AMG floor mats and stitched dash (even if it is Artico upholstery).

All grades now come standard with the 64-colour ambient lighting system. You should see the system fading through the colours at night and with the right music the whole effect is amazing.

The C-Class comes in four body styles: Sedan, Coupe, Estate (wagon) and Cabriolet.

Exterior and interior dimensions stay the same, all variants measuring about 4.7m in length. That’s a good size; not too big or small, making parking and manoeuvring in tight spaces pretty fuss-free.

The C-Class is made in various parts of the world, but I can tell you the C 200 Sedan we get in Australia is made at Mercedes-Benz's East London plant on South Africa's east coast.

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.

This depends on the body style, but being a mid-sized car practicality can be limited, but Mercedes-Benz has been clever with the way it has used the available space.

The boot, for example in the C 200 is 434 litres, which isn’t as big as the cargo space offered by the BMW 3 Series or the luggage capacity of the Audi A4. This is partly because the hybrid system uses space under the bonnet, so the car’s battery needs to go to the boot.

The C 300 doesn’t use the hybrid system and so the sedan in this grade has 455 litres of boot space.

Choosing the C 300 Coupe’s will reduce your luggage carrying ability to 380 litres and the C 300 Cabriolet’s cargo capacity varies from 360 litres with the roof up and 285 litres when it’s down and eating into the luggage area.

The Estate is the best luggage hauler but it’s still not enormous – the C 43 Estate that we test drove has a cargo capacity of 480 litres.

Legroom in the back of the C 43 Estate is good and at 191cm tall I can sit behind my driving position with about 20mm to spare thanks to the sculpted seat back.

Headroom is getting tight in the Estate and especially in the Sedan – well for me, anyway – and the optional sunroof will lower the ceiling height even further.

Up front space in the Sedan and Estate isn’t an issue with plenty of head-, leg- and shoulder room offered.

Storage throughout the Sedan and Estate is good with a large centre console storage bin, two cupholders up front and another two in the back along with a storage area in the fold down armrest, but all four door pockets are on the slimmer side. Still they can fit a small bottle of water, plus a wallet or purse.

That centre console bin houses two USB ports, and a 12-volt outlet can be found in the storage area under the climate controls – which also houses the optional wireless charging pad. Without the charging pad that small area is too tiny to place my iPhone8 Plus.

Rear headroom and legroom in the four-seater Coupe and Cabriolet is limited, but both get a pair of cupholders in the back and two more up front.

The range kicks off with the C 200 and its C 220 d diesel siblings, then steps up to the C 300. Prices for these grades have increased by $1500 in this update but you’re being given more features. Above the C 300 live Mercedes-AMG’s wild animals – the C 43 and C 63 S.

The C 200 Sedan now lists for $63,400 (plus on-road costs), and if you want the Estate version add another $2500, and an extra $4500 for the Coupe, while the Cabriolet is $25,000 more at $88,400.

The C 220 d Sedan lists for $64,900 and the only other form it comes in is the Estate for $67,400.

The C 300 Sedan lists for $71,400, the Estate is $73,900, the Coupe is $84,900 and the Cabriolet is $101,900.

The C 43 Sedan lists for $107,900, while the Estate is $110,400, the Coupe is $111,900 and Cabriolet is $124,900.

The C 63 S Sedan lists for $159,900, however, prices for other body styles have not yet been announced.

So, about all the stuff you’re receiving in return for the price increase – a 10.25-inch display screen replaces the smaller one in the previous car and it’s standard across the range. Don’t stab and poke at it like I did with my finger for hours, because it’s not a touchscreen.

Also new is the 12.3-inch fully digital instrument cluster, and it’s standard on all grades, too. Apple CarPlay and Android Auto come on all C-Class cars.

Other standard features, starting with the C 200 and C 220 d, include 'Artico' upholstery, which is a synthetic attempt at leather, a reversing camera, shifting paddles, dual-zone climate control, aluminium roof rails on the Estate, LED headlights, 64-colour ambient lighting and 18-inch alloy wheels.

The C 300 has the C 200’s features and adds leather upholstery, privacy glass (coupe only), proximity key and 19-inch alloys. The C 300 also gains the 'Driving Assistance Package' which I’ll tell you all about in the safety section below.

The C 43 picks up the C 300’s equipment and adds an enormous list of its own gear including a new AMG steering wheel, brushed stainless steel pedals, Burmester 13-speaker stereo, heated sports front seats, head-up display, wireless charging, intelligent LED headlights, panoramic sunroof, black roof racks on the Estate, analogue clock and 19-inch AMG alloy wheels.

Metallic paintwork is also part of the C 43’s standard features list which includes 'Obsidian Black', 'Iridium Silver', 'Mojave Silver', 'Cavansite Blue', 'Emerald Green' and 'Brilliant Blue', but you’ll have to pay for 'Hyacinth Red', which is a sort of candy apple red. Non-cost colours for the lower grades are non-metallic black and 'Polar White' non-metallic.

The C 63 S adds to the C 43’s equipment list with its own AMG steering wheel, illuminated door sills, digital TV tuner, nappa leather upholstery, an electronic rear differential lock, 19-inch alloys in matte black with high-sheen rim, plus high-performance brakes with red calipers.

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 previous C 200’s 2.0-litre 135kW/300Nm four-cylinder petrol engine has been swapped for a 135kW/280Nm 1.5-litre four-cylinder turbo-petrol with what Benz calls a ‘mild hybrid’ function.

This isn’t a hybrid with an electric motor driving the wheels, it’s an electrical system which is able to provide an additional 10kW/160Nm when accelerating. Known as the 'EQ Boost', the system also allows the C 200 to coast at a constant speed if the driver takes their foot off the accelerator. The battery is then re-charged when braking.

The C 220 d offers a diesel alternative and its new 2.0-litre engine now makes 18kW more power at 143kW and the same 400Nm of torque.

The C 300’s 2.0-litre turbo four has had a 10kW increase, taking power to 190kW, while peak torque is still 370Nm.

Also getting a power bump is the C 43 and its 3.0-litre V6 petrol is now good for 287kW (up from 270kW) while torque stays at 520Nm. The C43 uses Mercedes-Benz’s '4Matic' all-wheel drive system, while every other grade, including the C 63 S, is rear-wheel drive.

The C 63 S still makes an impressive 375kW and 700Nm.

The C 200, C 220 d, C 300 and C 43 all use the same nine-speed automatic transmission, while the C 63 S uses a ‘AMG Speedshift 9G’ which is a nine-speed dual-clutch auto.

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.

Fuel consumption obviously depends on the engine, but did you know the body type also affects mileage?

Mercedes-Benz says the C 200 Sedan uses 6.4L/100km over a combination of open and urban roads. The trip computer in our C 200 Sedan recorded 7.1L/100km after 254km of mainly country roads.

The C 200 Estate according to Mercedes-Benz will need 6.5L/100km, the C 200 Coupe uses 6.4L/100km and the C 200 Cabriolet will need 6.8L/100km.

Mercedes-Benz is yet to announce the C300’s fuel consumption figures.

The C 220 d Sedan is frugal with diesel fuel consumption being 4.7L/100km, while the Estate version needs 4.8L/100km.

Mercedes-Benz is yet to announce the C300’s fuel consumption figures.

The Mercedes-AMG cars are the thirstiest with the C 43 Sedan using 9.4L/100km, and the Estate will use 9.6L/100km. After 286km of country roads the trip computer in our C 43 Estate was reporting an average consumption of 10.3L/100km. The Coupe economy is 9.5L/100km and the Cabriolet needs 10.0L/100km.
 
The C 63 S Sedan puts it away at the rate of 10.4L/100km, and the Estate’s usage is 10.7L/100km, while the Coupe and Cabriolet’s fuel efficiency is yet to be announced.

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 Australian C-Class launch gave us the opportunity to drive the C 200 Sedan and C 43 Estate on a test route stretching from Melbourne's Tullamarine airport, roughly 300km north to Milawa in Victoria’s alpine region and back, with the conditions being dry and cool.

I knew the C 43 would be ridiculously fun, but you can’t eat your dessert first, right? So, I started in the C 200, which is far from just meat and three veg – it’s refined and enjoyable to drive.

Steering is well weighted and accurate, offering a better sense of connection to the road compared to some of its prestige rivals. The steering wheel itself felt good to hold, too – and this is on the base car.

The test car wasn’t without its options though and it did have the 'Dynamic Body Control Suspension' with its Comfort mode softening the dampers for a more compliant ride and the Sport setting for better handling.

And that ride was comfortable. The only disturbance to the serenity (we did go through Bonnie Doon) was a bit of wind noise created by what sounded like the wing mirrors.

Apart from that, the experience was serene – those seats up front are comfortable and supportive even after hours, the vision all-around is excellent and then there’s the engine, which is perfectly adequate.

Okay, 1.5 litres sounds small but the output is almost the same as the previous 2.0-litre and the 48 Volt EQ Boost hybrid system does provide just enough of a kick to get you away from the traffic lights or overtake without any discernible lag.

The hybrid system's coasting function is excellent – take your foot off the accelerator and your revs drop to zero but the car will maintain its speed. When you brake the battery is recharged so you’ll have the extra grunt again when you need it.

Now for dessert. Just idling the C 43 sounds sedate, but that’s with the exhaust note and engine in the Comfort setting. It means you can pull into your street at night or start it up early in the morning without waking the up the entire neighbourhood.

The C43 isn't as vicious as the V8 C 63 S, but that’s the appeal of it.

Or, to hell with them, the people next door are jerks anyway: put it in Sport and the twin-turbo petrol V6 snarls and crackles as you shift through the gears. It’s not as vicious as the V8 C 63 S, but that’s the appeal of the C 43 – it’s a milder form of wild that’s easier to live with, but still so much fun.

The back roads from Milawa to Mansfield were a great testing ground for the C 43 Estate with their hill-climbing bends and downward forest runs. Merc AMG claims the C 43 can accelerate from 0-100km/h in 4.7s, and while that’s more than half-a-second behind the C 63 S, it’s still plenty quick.

With fantastic turn-in, all-wheel drive offering superb traction and great grip from the Continental ContiSportContact rubber (225/40 R19s front, 255/35 R19 at the back), a smooth-shifting nine-speed, impressive brakes and that turbo V6 which pulled the car heroically out of corners, it was hard not to grin like an idiot.

Only my mouth hurt afterwards, not my body. There’s a line you’re not going to read in any other car review. Some sports cars have a ride so firm, and seats so hard, and driving positions with hip points so low, that I almost have to leave the vehicle on all fours.

But only my face hurt from smiling so much – you could pilot a car like the C 43 until it ran out of fuel from a full tank and still feel comfortable – which is almost what we did. How much fuel did it use? Keep reading to find out.

The C-Class was awarded the maximum five-star ANCAP rating when it was tested in 2014. The base grade C 200 is fitted with nine airbags, AEB which works most effectively at lower speeds, and blind spot warning.

Stepping up to the C 300 brings the 'Driving Assistance package' which adds a more sophisticated AEB with cross traffic function and evasive steering, plus lane keeping assistance.

No spare tyres here. The C 200, C 220 d and C 300 all come with run-flat tyres, while the Mercedes-AMG grades have a puncture repair kit.

For child seats, you’ll find two ISOFIX points and three top tethers across the back row of the Sedan and Estates, while the Cabriolet and Coupe have two ISOFIX points in the back.

There are also two hi-viz vests in the cargo area and, yes, you do get a warning triangle, too.

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 C-Class is covered by Mercedes-Benz’s three-year/unlimited kilometre warranty. We’re keen to see Mercedes-Benz move to longer warranty periods as is becoming the norm with mainstream brands, many of which are offering five year coverage.

Servicing is recommended at 25,000km/12-month intervals for the regular C-Class cars and the C 43. The C 63 S needs servicing every 20,000km or annually.

It’s great to see Mercedes-Benz offers capped price servicing. For example, the C 200 will cost you $396 at its first service, the second is $792 and the third is also $792.
