Mercedes-Benz C-Class

Summary

Audi RS4

Think about the word ‘functional'. You might notice that there are three letters at the start of the word that people don't often associate with station wagons. That's not the case for the 2018 Audi RS 4.

This isn't your everyday station wagon. It's a hyperbole-generating monster - a family-friendly estate with a licence to punish. Audi goes as far as to suggest that it offers "supercar performance and everyday practicality".

And why wouldn't it? With a bolshie engine, all-wheel drive and more grunt than a pair of conjoined twin hot-hatches, it's a model that has little to prove... especially to those people who appreciate what those precious first three letters can do to improve a drab drive in city traffic.

But there's something that can't be understated about this new-generation RS 4: it isn't like the model that came before it. There's no V8 engine under that shapely bonnet, because of the  the new RS 4 isn't like the old one. The V8 is gone... and yes, when I first read that Audi had done the unthinkable and pulled the bahnstorming eight-cylinder screamer in favour of a downsized twin-turbo six I was shocked and horrified.

Without its star attraction, could it still be fun? I don't want to spoil the story, so be sure to read on to find out...

Do you know how many bones you have in your body? Stop counting, there are 207. And if say half those bones were replaced with different ones would you consider yourself to still be the same? Well that’s what Benz has done with the new C-Class – sort of. Of the roughly 13,000 parts which make up a C-Class car, 6500 of them have been modified or changed.

You don’t need to know every change to the new C-Class, but at the end of this review you will be across the differences that you can see, feel and hear.

Just a note before we start. The top-of-the-range Mercedes-AMG C63 S arrives in early 2019 and wasn’t available to drive at the Australian C-Class launch. That’s why we’ll focus on the other grades here - the C 200, C 220 d, C 300 and C 43. We’ll test drive and review the Australian C 63 S when it arrives – promise.

Verdict

Audi RS48.3/10

There is no doubting that the all-new Audi RS 4 is a pragmatic option, probably more so now than ever before. It does the dual-personality thing better than the model that came before it, and perhaps better than anything else at this price point, too.

If you want a practical family wagon that just also happens to be punishingly fast, and you have the budget to consider something like the new Audi RS 4, it should be on your shopping list. And probably towards the top, too.

Mercedes-Benz C-Class7.9/10

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.

Is the C-Class still the king of the mid-sized prestige world? Tell us what you think in the comments below.

Design

Audi RS49/10

If you like wagons, you'll totally get it. If you're a hater, or even ambivalent, then you'll probably still get it.

Admittedly it could look even more aggressive, but it has to balance practicality with pouncing killy animal aggression. Even so, I think there's a lot to like here, from the squared-off front and rear quarter panels, the broad (even broader than the regular A4 range, in fact) 'single-frame' grille, and the bejewelled looking LED headlights.

It looks even better from behind, with the broad rear haunches really hunkering it down, and the wide tail-lights and sneaky little fake vents on the side adding extra back-end bulk. Note: the rear light-edge vents may be fake, but the front ones actually work to channel air to cool the brakes.

There are 20-inch wheels in a few different designs, but my personal choice would be the milled aluminium single-piece ones you see on the blue car in these images. They're gorgeous, even if they cost more. And I couldn't not have the signature Nogaro Blue Pearl, which was the same colour as the RS 2 wagon that started the hot wagon thing for Audi... again, at a high price.

Thankfully, I wouldn't need to spend an extra cent inside, because the interior is lush. There are all the typically Audi finishes - it's a high-end and luxurious environment, but with lashings of sporty elements that help it feel almost like a leather tracksuit. Take a look at the pictures of the interior to make up your own mind.

Compared with, say, a regular A4 Avant, the RS 4 Avant is bigger in every way except height. It measures 4781mm long (up 56mm), 1886mm wide (up 44mm) and 1404mm tall (down 30mm). It's quite heavy, too, weighing in at 1800kg, which is about 150kg more than the entry-level wagon.

As good as it looks, I just can't help but think maybe it could have been even more aggressive. The last model certainly had muscle and more macho with its even more angular guards. But maybe the world has moved on a bit, and I'm just not ready for it.


Mercedes-Benz C-Class8/10

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.

Practicality

Audi RS48/10

This generation of Audi A4, S4 and RS 4 models really puts the flame to the competition in terms of user-friendliness, high-tech execution and style... if not 100 per cent nailing the "wow" factor.

Don't get me wrong, it's still a very, very pleasant place to be. Typically Teutonic, typecast technical Audi, but with some sporty flourishes. The hard-backed sport bucket seats up front offer a great amount of adjustment (though the driver's seat base is a little too high), and depending on what interior trim you opt for, you may see aluminium or carbon finishes throughout.

The quilted leather is lovely, and the materials are all superb - so is the fit and finish. One of the cars I drove had an optional pack with Alcantara trim, with that material covering the shifter and steering wheel - the latter of which I love, because it's smooth yet grippy. I'm not so sold on manual steering adjustment for a car at this price point, however.

With the Audi Virtual Cockpit digital screen spreading 12.3-inches in front of the driver, there's no shortage of info to choose from. It's been around a few years now, but I still love the look of Google Maps in front of me.

There's also Audi's MMI touch system, a rotary dial with a touchpad on top that is pretty simple to use, and it links up to a high-resolution 8.3-inch screen on the dash top. All the connectivity stuff you'd expect is included - Apple CarPlay, Android Auto, Bluetooth phone and audio, DAB+ digital radio, and an inbuilt hard-drive for your own music storage. You won't be left wanting for entertainment.

There are reasonably good sized cup holders up front, a covered centre console, some loose-item storage areas and adequate bottle holders in all four doors. The back seat has mesh map pockets (set on hard plastic seatbacks - good for limited damage to fabric if you have children who like to kick the seat) and a flip-down armrest with cupholders.

Space in the rear is easily good enough for a six-foot (183cm) tall adult like myself to slot behind someone of the same size, with ample kneeroom, good toe room and enough headroom to ensure no hairs were out of place. The width is surprisingly decent, too.

There are dual ISOFIX child-seat anchor points, and three top-tether attachments as well. And parents (and children alike) will appreciate the rear air vents, and three-zone climate control system that allows a seperate temperature in the back.

The boot is a good size, with 505 litres of capacity up to the multifunctional luggage cover (which includes an integrated mesh cargo barrier and operates electronically in conjunction with the boot lid). It also has a reversible floor section - carpet one side, plastic on the other - perfect for tying down wet clothes (using the included mesh elasticated web net) or even performing potentially messy nappy changes. The boot expands to 1510L with the seats down.


Mercedes-Benz C-Class7/10

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.

Price and features

Audi RS48/10

The new twin-turbo V6 model is priced at $152,900 plus on-road costs, which represents a slight hike over its V8-powered predecessor, but Audi claims to have added $22,000 of extra equipment.

Standard inclusions offered in the RS4 consist of 20-inch alloy wheels, red RS brake calipers, an adjustable sports exhaust system, Audi's sport differential, adaptive sports suspension, LED headlights with LED daytime running lights, adaptive rear LED indicators and tinted rear windows with acoustic front glass.

Standard interior kit includes Audi's 'Virtual Cockpit' 12.3-inch driver info screen with configurable RS display mode, an 8.3-inch tablet media screen with sat nav, Bluetooth phone and audio streaming, Apple CarPlay and Android Auto phone mirroring, DAB+ digital radio, and a stonking 19-speaker Bang & Olufsen stereo system.

The front sports seats with Nappa leather trim and honeycomb quilting (which apparently mirrors the design of the grille mesh) also feature bolster adjustment, massage function, memory settings for the driver's seat and electric adjustment and heating for both sides. There is an ambient-lighting system with 30 different colour options, too.

A panoramic sunroof is fitted as standard, but for hot areas of the country it can be deleted if the buyer so chooses. Smart key entry and push-button start is standard, and there's an auto tailgate with gesture control.

Even though that list is long, there are still option boxes you can choose to tick. Things like the carbon and black styling pack ($11,900), the 'Technik Pack' (with head-up display, Matrix LED headlights, wireless phone charging - $3900) and other style-focused extras like the 20-inch milled aluminium wheels ($1600). There are several colour options to choose, including the Misano Red pearl finish ($1846), or the brilliant 'Nogaro Blue Pearl' ($5450)... but not all the colours cost money, with a selection available at no cost.

See below for the extensive safety kit list - because it's hugely lengthy!

As for where the competitors sit, the Mercedes-AMG C63 S wagon lists a little higher, at $159,711 plus on-roads. There's no BMW M3 wagon, but the sedan version is $141,610 plus costs... and it's the only one with manual or auto to choose from. There's no Lexus, Infiniti or Volvo equivalent model. But I guess you could consider the S4 a good alternative at $50,000 less, and it's available as a sedan or a wagon...


Mercedes-Benz C-Class8/10

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.

Engine & trans

Audi RS49/10

This isn't the first time the Audi RS 4 has had a twin-turbo V6 engine under its bonnet. Back in 2000, the very first RS 4 launched with a 2.7-litre biturbo engine.

This all-new model has a 2.9-litre twin-turbo unit, which shares much with the Audi S4 and S5 models (they run a 3.0-litre turbo - the engine in the RS 4 is a smaller capacity and has a shorter stroke, but adds a turbo over the lesser S models).

It's no V8, however. The most recent model before this one had a 4.2-litre naturally aspirated unit with 331kW of power and 430Nm of torque.

This new version carries over the same power output - 331kW - but it hits between 5700-6700rpm, not at 8250rpm like the old V8. And torque has seen a substantial kick up the behind, now rated at 600Nm.

Not only has torque increased by about 45 per cent, it's also across a broader rev range - now it spans 1900-5000rpm, where it was not only lower but shorter-lived and less usable in the V8 (4000-6000rpm).

And the all important 0-100km/h time? It's now at 4.1 seconds, where it used to be 4.7sec. The top speed remains identical - 250km/h.

What about the sound, though? Read the driving section below... or better yet, watch the video!


Mercedes-Benz C-Class9/10

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.

Fuel consumption

Audi RS48/10

Fuel consumption for the 2018 Audi RS 4 is rated at 8.9 litres per 100 kilometres, which is fairly good for a vehicle with this much propulsion potential. CO2 emissions are rated at 202g/km.

Both of those are big improvements over the V8 that preceded it - the claimed consumption was 10.7L/100km and emissions were 249g/km.

But it's worth noting that Mercedes-AMG has the C63 wagon with a 4.0-litre twin-turbo V8 that has more power (375kW) and torque (700Nm) yet uses less fuel (8.7L/100km).


Mercedes-Benz C-Class8/10

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.

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.

Driving

Audi RS48/10

It only took three corners for me to feel 100 per cent comfortable with the controls of the Audi RS 4. Some cars may take a few minutes before you become accustomed to how the throttle, brakes and steering want to be used, but it was mere seconds in this case.

That's because of the outright predictability of the RS 4 - it's hard to set a foot wrong, with excellent throttle response, strong but progressive braking, and better steering than I've experience in any Audi outside of the R8. It's not perfect - there's still a little bit of deadness or stickiness on centre - but I like the way it helps you pivot the car and apply lock at pace, thanks to nice weighting and resistance. The steering is light when you want it, and hefty when you need it.

The adaptive dampers and 20-inch wheels can't totally divorce the road surface from the bodies of the occupants in the cabin, and over patchy surfaces the ride can be a little pitchy, even in the Comfort setting.

But those dampers help stiffen the chassis up in Sport mode, negating body roll brilliantly. That, combined with the traction of the excellent quattro all-wheel drive system with a self-locking centre differential, and the grip of the Continental tyres makes for a really enjoyable way to cut through a series of corners.

Of course there are electronic helpers underneath, including a torque-vectoring-by-braking system and torque-splitting rear differential that pushes load to where it's needed most - but unless you had a screen in front of you telling when they were being used you wouldn't know. It all just feels really natural in the way it handles itself.

Now, that engine.

No, it isn't a V8, but what it is is a powerhouse weapon. It's still rev-happy, and the transmission allows it to be that way: in Dynamic mode with the shifter in S (not D) there is a brilliant willingness to the way it hangs on to gears - through a series of sweeping corners, getting on and off the throttle and brake pedal respectively, it had incredible intuition - third gear was the most usable, and gave the most, too.

The engine's sound isn't as visceral as the V8 of its predecessor, but it isn't what I'd call dull. There's a nice bit of chortle on the overrun, and it sounds pretty menacing when you punch the go pedal.

In normal driving, too, it's well suited to regular duties. It just so happens that its great at going fast, which is what you want from an RS model.


Mercedes-Benz C-Class8/10

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.

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.

Safety

Audi RS49/10

There is no model-specific Audi RS 4 Avant crash-test rating, but the Audi A4 (four-cylinder) range managed the maximum five-star EuroNCAP / ANCAP test score in 2015.

Rest assured, though, the RS 4 has a lot of standard equipment.

The standard safety equipment list includes Audi's pre-sense front system with auto emergency braking (AEB) with pedestrian detection (which works up to 85km/h), plus a 360-degree camera with reversing camera and front and rear parking sensors. Plus the traffic-jam assist system, which debuted in 2015 on the Q7 and uses two radars to read the road ahead - even scanning in front of the car directly in front of you.

There's active lane-keeping assist, lane-departure warning, blind-spot monitoring, adaptive cruise control, turn assist (which will stop you from driving through an intersection if the car doesn't think you'll make it), auto high-beam lights, rear cross-traffic alert (with audible, visual and physical notification - it can jolt the brakes if you aren't paying attention), multi-collision braking (which will stop the car if you have an accident to prevent further mishap).

There's also Audi's clever "exit warning system" that will flash the ambient lights if an occupant is about to open their door into the path of oncoming cars or cyclists.

The RS 4 has eight airbags (dual front, front side, rear side and full-length curtains).

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.

Ownership

Audi RS47/10

Audi covers all of its models with a three-year/unlimited kilometre warranty plan, which, by market standards is starting to look a little low, but in the premium part of the market, not many brands do much better.

As for servicing costs, it's a bit of a guessing game. The entire RS model range, as well as the R8 supercar, isn't covered by the same Audi Genuine Care pre-purchase setup you can get on a regular (non RS) model. That plan covers three years/45,000km of maintenance, and in the case of the A4/S4, the cost is $1620. Expect more than that for the RS 4.

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.
