Audi RS5 vs Mercedes-Benz C-Class

What's the difference?

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?

The Mercedes-Benz C-Class C200 is such a stylish sedan and I would totally have one. The driving performance, luxurious features and practical size made it a winning combo for my family. The price point is definitely up there but you do get a high-end build for the cash. I've seen bigger boots in other sedans and not being able to fit a third child seat will limit some families, but this still easily earns an 8.5/10 from me.

My son really loved this one. The ambient lighting was the highlight for him and he thought it looked like a "space car" inside. He gave it a 9/10.

I defy anyone to describe the RS5, and especially the Coupe, as anything but stunning. Seriously, the near perfect proportions and swept-back styling make it look fast even when it's parked. 

Up front, there's a new-look black-mesh grille that's been given a 3D effect, like it juts out over the road in front it, while the thing headlights have been carved back into the body work like they're been windswept under hard acceleration.

The 20-inch darkened alloys fill the arches, too, with a sharp body crease that runs from the front headlight all the way back to the bulging shoulder lines above the rear tyres accentuating the curves.

Inside, the RS5 is a sea of black Nappa leather and sporty touches, and we particularly like the chunky, flat-bottomed steering wheel, which both looks - and feels - great.

The C200 is a sleek and elegant steed.

Initially, you may think this is just a standard Merc showcase. There's the nice big badge on the pronounced nose. Beautiful sleek lines in the body... but it's the attention to detail that make this feel special.

There's a repeated badge motif in the grille and a cute cursive Mercedes logo tucked into the corner of the windscreen. The puddle lights on the doors project the badge at night time and you can often spot a badge etched into the LED lights.

However, it's the interior that's the highlight for me and I feel like it's a big step up from previous models I've been in.

Our model has the grey 'Artico' synthetic leather trim (says grey but it's really white) and a lovely mix of piano black and shiny chrome inserts that are set against soft touchpoints throughout.

The quality of the build oozes through every stitch and join. Don't even get me started on the cool customisable ambient lighting system inside, which makes this feel like you're on the set of Tron and really elevates the interior.

It's quite fun to build one of these in Mercedes' online configurator. You can customise your trims to make it feel like your own and their blue paintwork options are great (I do love a blue car).

We only tested the Coupe, and I can tell you that the practicality perks on offer largely depend on where you're sitting.

Up front, you're spoiled for room in the two-door Coupe, with the two spacious seats separated by a sizeable centre console that's also home to two cupholders and a variety of cubbies, with extra bottle storage in each of the front doors. 

The back seat, though, is a little, or a lot, tighter, with come acrobatics required to even climb into it, given the Coupe only has two doors. The Sportback offers two more doors, which will surely make the process a little easier. 

The Coupe measures 4723mm in length, 1866mm in width and 1372mm in height, and will deliver a decent 410 litres in luggage space in the boot. The Sportback measures in at 4783mm, 1866mm and 1399mm, and boosts your luggage space to 465 litres.

Either vehicle has your tech needs sorted, with an abundance of USB and power outlets serving both front and backseat riders.

I'm not going to lie – there are sedans out there that have an almost limo-like space inside but the C200 isn't one of them.

It's not small by any means and all occupants enjoy the comforts of decent legroom and headroom but it's not cavernous considering the specs (1437mm high/1820mm wide/4751mm long).

The optional panoramic sunroof does cut into the headroom for back seat passengers, which is something to consider if your family is very tall.

The storage is maybe a tad leaner-than-average for a car of this size. The glove box and middle console aren't massive but will suffice.

The cupholders up front can be removed if you need extra storage space for larger items and back seat passengers enjoy retractable cupholders in the armrest.

The way the front doors curve out creates a larger than normal storage bin and drink bottle holder – which help make up the difference. There is a dedicated phone pocket, to tuck it out of the way.

The boot space is 455 litres (VDA), which isn't as large as some others on the market but it was plenty big enough for my family's needs.

There's a handy under-floor storage pocket for smaller items, like the puncture repair kit, because you don't get a spare tyre in this.

When it comes to ease of use, my six-year-old loved not needing my help to get into his seat and he still enjoyed a decent view out of the wide back window.

The amenities in each row are good but not class-defining. Still, creature comforts have be well-thought through.

Front occupants enjoy heated seats and fantastic lumbar and under thigh support. Dual-zone climate control sorts out the temp, and the cool circular air vents that make loud audible 'clicks' when manoeuvred give the interior a jet cockpit vibe.

While I've never had an issue opening or closing a sedan boot, the powered lid was a nice feature to have this week.

The tech throughout is great and intuitive to use. The massive 11.9-inch touchscreen multimedia system is cool and is easy to use once you become acclimatised to Mercedes system.

The customisable digital instrument panel makes the driving experiences feel individualised.

The interior is a chilled out space with gentle scrolling touchpads taking the place of most 'push' buttons and dials.

Think of each surface as being a bit like a touchscreen tablet in how you operate it. I was a little worried the touchpads would be laggy but they're very responsive.

There's only one USB port in the whole car, which limits charging for other passengers but I did enjoy the easy connectivity of the wireless Apple CarPlay.

The electric heated front seats are a nice touch but I was amused by the 'kinetic' function on both. It's what you might call a 'massage' function on another car but here they don't really work. It's best to think of them as a way to do some (very) gentle stretching on a long trip.

The 360-degree camera view is super clear and crisp but the dynamic guidelines (which tilt the camera angle) are a bit too dynamic for my liking and I relied mostly on the bird's eye view to park.

As I've mentioned, the ambient lighting system creates a stellar atmosphere inside. I've often wondered why other car manufacturers haven't jumped on that bandwagon because it's a relatively cheap way of creating wow factor. And it generates massive wow factor in here.

Herein lies the rub. There are four models for the C-Class sedan and ours is at the bottom of the pack.

But don't let its position fool you in thinking it'll be cheap because this model starts at $78,900... and that's before you start adding the option packs. 

Our model is fitted with the 'Vision Package' which adds a host of features – like a panoramic sunroof, head-up display and heated front seats, to name just a few. This adds about $3000 to the price tag.

This also has the optional 'Sport Package' which adds 19-inch AMG alloy wheels and rear privacy glass, among other things, for an extra $1300.

Unfortunately, even without all of those options, this is still one of the most expensive 'entry-level' sedans in the luxury class!

Its a terrific engine, this - a twin-turbo 2.9-litre six-cylinder TFSI that will deliver 331kW at 5700rpm and 600Nm at 1900rpm, sending it thundering to all four wheels (because quattro) via an eight-speed tiptronic automatic.

That's enough, says Audi, to deliver a 0-100km/h sprint time of 3.9 seconds in the Coupe and the Sportback. Which is very, very quick.

The C200 has a 1.5-litre, four-cylinder, turbo-petrol engine with an integrated starter-generator. 

What's that, you ask? So, glad you did. It's basically an electric battery that also acts as your starter... or alternator.

It smooths out vibrations from the engine and generates some power from braking. Making this a very mild hybrid. Note the 'mild'.

Is it powerful? Surprisingly, yeah. It has a maximum output of 165kW and 300Nm of torque. Combine that with the starter-generator and we have a powerful little engine that can push the C200 from 0-100km in 7.3 seconds, while still feeling like there's power in reserve.

The nine-speed auto transmission is damn smooth and there's no clunky gear changing at any speed. It's got great pick-up, too, for when you need to overtake or zip across traffic.

The RS5 Coupe will sip a claimed 9.4L/100km on the combined cycle, and emit a claimed 208g/km of Co2. It's fitted with a 58-litre fuel tank. 

The RS5 Coupe will the same 9.4L/100km, but emit 209g/km of Co2.

The official combined cycle fuel figure is 6.9L/100km. Real world testing saw my figure at 7.2L, which was awesome for the heavy driving I did this week on a combo of urban and open-roads.

The light regen braking probably helps this coast comfortably into being a very efficient sedan for its size.

Minimum fuel requirement is 95 RON premium unleaded and you'll need 66 litres of it to fill the tank.

Driving range using the official consumption figure is around 950km, and 915km using our real-world number.

With our time behind the wheel limited to the RS5 Coupe, we can only really report on how the two-door feels on the road, but given the prodigious power on offer, it's unlikely the addition of two doors is going to make the Sportback any slower. 

In short, the RS5 is thunderously fast, collecting speed with utter nonchalance thanks to this thick and endless-feeling supply of power unleashed whenever you plant your right foot.

It makes even the most ham-fisted attempts at cornering feel fast as lightning, with the power flow able to make up for every slow entry and exit by simply piling on pace between bends. 

But that's what you expect from an RS model, right? So perhaps more impressive is the RS5's ability to transform back into a relatively sedate urban cruiser when the red mist subsides. The suspension is firm, especially over rough road surfaces, and you do need to be a little careful with the accelerator to avoid that lurching feeling at every green light, but driven calmly, it doubles as a everyday car quite nicely.

Like in the RS4, we did find the gearbox felt a little quick to change at pace, shifting up or down at strange moments on the way into or out of corners, but you can reclaim control via the paddle shifters.

The steering feels solid and concise. The tyres seem like they're glued to the road, making winding roads downright fun to tackle. Oh, and the sharp 11 metre turning circle is wonderful.

The handling makes this your best friend in a car park. The lower ground clearance did elicit some unladylike grunts when I parked on a hill, but otherwise the wide door apertures makes it easy to get in and out of.

The only thing I would note is the low-profile ground clearance. Just be aware of your speed and angle when you handle car park ramps or road bumps in this. They are not your friends.

The safety sheet is well-stocked and has the usual suspects you want in a family car, like: AEB with car, pedestrian, cyclist and junction turning assist (effective speed 7.0-90km/h); forward and back-over collision warning, lane keeping assist, lane departure warning and emergency lane keeping assist, as well as, blind-spot monitoring.

I quite like the 'Active Distance Assist' which helps to automatically slow your vehicle speed to keep a set distance to the car in front in stop-start traffic.

Perfect for those busy city commutes. And if you're not confident on parking, this also has a 'Park Assist' feature.

It's nice to see that this has nine airbags, which include a driver's knee airbag and the newer front centre airbag.

This has a maximum five-star ANCAP safety rating which is nice and new from testing done in 2022.

There are ISOFIX child seat mounts on the outboard rear seats and three top tether anchor points but because of the narrower rear seat, you'll only comfortably fit two side-by-side.

It was super easy to fit my seats and there's a good amount of room for front passengers when a 0-4 rearward facing child seat is installed.

Audi vehicles are covered by a three-year, unlimited-kilometre warranty, which is feeling more than a little underdone when compared to some competitors.

Services are due every 12 months or 15,000kms, and Audi allows you to pre-pay your service costs for the first five years, at a cost of $3,050.

The C200 comes with a five-year/unlimited km warranty, which is standard for the market.

There are multiple servicing options and on the five-year plan, the services average $1090 annually, which is quite expensive.

Servicing intervals are pretty good at every 12 months or a longer than usual 25,000km, whichever comes first.
