Audi S7 vs Mercedes-Benz C200

What's the difference?

Audi’s S7 Sportback wraps style, comfort and sportiness in an appealing package that is sure to please onlookers and occupants alike.

The great engine/transmission aside, the S7 Sportback also has cutting-edge technology at a more affordable pricetag, though less-than-comfortable rear-seat space lets it down a little.

We wish the car we sampled didn’t have the all-wheel steering, as we much preferred the more neutral feel of the S6 sedan we also drove but, overall, the S7 Sportback puts forward a strong case for its existence.

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.

Audi’s second-generation A7 has always been a bit of a looker, but Audi has taken it up another notch in the S7 Sportback.

Differentiating the S7 Sportback is a more aggressive bodykit, complete with larger air intakes up front, blacked out exterior trim, quad-exhaust tips (denoting that it’s an Audi Sport model) and large 21-inch wheels

The S7 doesn’t go too overboard with the aggressive appointments however (that’s what the top-spec RS7 Sportback, due here later this year, is for), but balances its sportiness with a stately aesthetic.

We think the S7 Sportback is stunning, especially the white exterior colour that gives it an almost Stormtrooper-like look, but even our test car, finished in Daytona Grey, while much more subtle, is still easy on the eyes.

We especially like the strong shoulder line, chiselled doors and sloping roofline of the Sportback body style that combine in profile to make the S7 look like a sprinter on the starting blocks ready to pounce.

Inside, the S7 Sportback scores all of Audi’s latest interior technology, including a 12.3-inch Virtual Cockpit instrumentation and dual-screen centre console layout.

The triple screen set-up definitely helps the S7 Sportback feel very cutting-edge from the driver’s seat, especially when you start to play around with the multimedia system that sports haptic feedback when you press the screen.

Everything is laid out in a clear, concise and easy-to-use manner, while the surfaces of the dashboard are covered in soft-touch, premium materials.

If we’re being honest, we'd probably skip the red-leather interior of our test car in favour of something a little more subdued, but to each their own.

We like the integrated air-vents that blend well into the dash, while the sea of black is broken up with some aluminium detailing and different finishes.

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).

Measuring 4969mm long, 1908mm wide, 1417mm tall and with a 2928mm wheeblase, the S7 Sportback falls well and truly into the large car class.

Up front, the driver and passenger have plenty of room, while the seats and steering wheel are almost infinitely adjustable to find the perfect position.

As you can imagine though, the sloping roofline does eat into the rear-seat headroom a little.

The outboard seats offer plenty of leg- and shoulder-room, but the slanted roof prevents my six-foot-tall frame from sitting up straight comfortably.

Don’t get me wrong, the space is perfectly useable for children or even some smaller adults, but don’t expect to get any basketball players in those seats.

As for the middle seat, only children will find it comfortable due to the protruding transmission tunnel and higher-set seat.

The S7 Sportback’s boot offers at least 535 litres of space and expands to 1380L with the 40:20:40 split-fold rear seats stowed.

Being a liftback (or Sportback in Audi parlance) means the boot is much more practical than a standard sedan, and with such a large aperture, bigger items such as suitcases or golf clubs won’t be annoying to load and unload.

Bag hooks, storage tie-down points and carbo netting also feature to ensure your goods don’t roll around when the S7 Sportback is in motion.

Storage around the cabin though, could be a little better as the wireless smartphone charger takes up a fair chunk of room in the shallow central storage bin under the front armrest.

The usual storage tray found ahead of the shifter is also absent, due to the dual-screen centre console layout, but two generous cupholders and sizeable door pockets are still available up front.

Second-row passengers get access to a fold-down armrest with shallow storage tray and cupholders, as well as door pockets that can accommodate large bottles.

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!

Powering the new S7 Sportback is a 2.9-litre twin-turbocharged petrol V6, punching out 331kW/600Nm, which is paired to an eight-speed automatic transmission that sends drive to the road via Audi’s quattro all-wheel-drive system.

The result is a zero-to-100km/h acceleration time of 4.6 seconds.

Keen-eyed Audi fans might note that those are the exact same engine and outputs as the RS5 Sportback, RS5 Coupe and RS4 Avant, and they’d be right, however, Audi has added the 48-volt mild-hybrid and an electric powered compressor (EPC) to reduce turbo lag in the S7 Sportback.

It’s a similar system first employed in the SQ7 large SUV, and basically means that the EPC is spooling up the turbo at low engine speeds for better off-the-line performance.

The mild-hybrid technology no doubt helps shift the S7 Sportback’s 2040kg weight with peak power now available earlier on in the rev range (from 5700rpm), while maximum torque is available from 1900rpm.

Compared to the older car, the new S7 Sportback matches its predecessor in power, but ups torque by 50Nm despite losing the old car’s 4.0-litre twin-turbo V8 engine.

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.

Official fuel economy figures for the S7 Sportback are 8.5 litres per 100km, but in our brief time with the car we managed 13.6L/100km, mainly due to the inner-city and country B-road driving.

The 48-volt mild-hybrid system works to reduce fuel usage, by as much as 0.4L/100km according to Audi, and allows the car to coast with the engine off between speeds of 55km/h and 160km/h for up to 40 seconds.

The start/stop system also aids in reducing fuel usage.

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.

Audi’s formula for a go-fast vehicle has always been simple – quattro all-wheel-drive for grip, potent engine for speed – and the new S7 Sportback remains true to that formula.

We are big fans of the 2.9-lite twin-turbo V6 engine, which is matched wonderfully with a smooth-shifting eight-speed automatic transmission.

The S7 Sportback always seems to have plenty to give no matter where you are in the rev range, and the transmission isn’t bogged down with slow gear changes up or down.

Though it’s hard to tell how much the EPC helps in getting the S7 up to speed, if you have you window down and accelerate hard from a standstill, you can hear the electronics whirring away.

The standard air suspension also does a wonderful job at absorbing road imperfections in comfort, while it can be switched over to dynamic for a more sporting characteristic.

Grip is plentiful thanks to 255/35 tyres and the quattro all-wheel-drive system but, as with other Audis, the S7 Sportback tends towards understeer when pushed hard around a corner.

Being such a long and wide model, you definitely feel the S7 Sportback’s size on the road, especially when navigating through quick direction changes, but this is where the $7700 Dynamic Package comes into play.

It adds a sports differential, variable ratio steering and all-wheel steering, all aimed at sharpening the S7 up in the bends.

Our test car was fitted with the option pack, but it left us a little cold.

The all-wheel steering especially, made the S7 Sportback’s handling feel too artificial for our tastes, and we were never able to gauge where the rear end wanted to go in a corner.

If we were buying one, we’d leave the Dynamic Package option box unticked.

Bringing the S7 Sportback to a stop are big 400/350mm brake rotors front/rear, with six-piston callipers in the front.

Ceramic brakes with grey-painted callipers can be optioned for $18,000, but the standard stoppers do a fine job scrubbing speed in the S7 Sportback.

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.

Like all new Audi models, the S7 Sportback comes with a three-year/unlimited kilometre warranty with three years roadside assist.

Audi’s warranty still lags behind Mercedes-Benz and Genesis, two premium marques that offer a five-year/unlimited kilometre warranty on their models.

Scheduled service intervals are every 15,000km/12 months, whichever comes first.

A three- or five-year service plan is available for the S7 Sportback, priced at $2350 and $4110 respectively.

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.
