Mercedes-Benz C-Class vs Mercedes-Benz AMG GT

What's the difference?

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.

This is no Lotus, but damn if it ain't a hell of a good time, and proof positive that electrification can enhance the V8 experience, rather than ruin it.

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).

It's a mean, but somehow still sleek, looking beast, this big AMG, but it's also immediately recognisable as a thing of intent.

Up front, there's the huge vertical-slat grille that looks like it drove straight out of a Stephen King novel, a massively domed bonnet, and these vacuum-like side intakes that look like they could suck in stray animals.

Then, at the back, there are twin dual-pipe exits (for four in total), and an automatic wing that pops out of the rear bodywork. And all of that's capped off with these massive 21-inch forged alloy wheels hiding golden ceramic-composite brakes.

Mean, yes, but not quite as aggressive as you might expect the most powerful AMG to date to come across, perhaps.

Inside, it's more subdued again, with the AMG presenting a pretty passenger-friendly space, with all the Benz tech you'd imagine, including the massive screens, and — thanks to its air suspension and drive modes — the ability to tailor the ride to your liking, meaning a comfortable and premium experience, despite the power under your right foot.

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.

It's not overly practical, given its size, with AMG locking in a four-seat configuration with a fixed rear pew that limits boot space. You can get folding seats, but only as part of an option package.

What you're left with is a vehicle that stretches 5054mm in length, 1953mm in width and 1447mm in height, but that serves up rear seating for only two – albeit very comfortably – and, because of the electric battery and motor being housed at the rear, boot space of just 335 litres.

There is triple-zone climate control, and the rear seating is lounge-like and luxurious, while the up-front space is ample for two full-size riders, too.

There's no spare, with AMG's 'Tirefit' puncture repair system on board.

There's no escaping the fact that a big number has been applied this AMG E Performance model in Australia, with the GT63S commanding $399,900, before on-road costs, and before you start selecting option packs.

Obviously performance is what you're really paying for here, but there are lots of niceties included, too.

They include an electric glass sunroof, 21-inch forged-alloy wheels with ceramic composite brakes, rear-axle steering, puddle lighting, power-closing doors (only sealing, not full hands-off closing), LED lighting, and an auto rear wing that retracts back into the body work at the rear.

Inside, there are twin 12.3-inch screens with Apple CarPlay and Android Auto, a Burmester sound system, Nappa leather seats front and back (which are heated and cooled in the front, and which offer a massage function), and three-zone climate control.

You can then spring for the 'AMG Night Package' ($3490) which adds the 'AMG Night Exterior Package', different 21-inch wheels in matt black, dark tints on the rear glass, black badging and dark chrome on the grille.

Then there's the considerably more expensive 'AMG Carbon Fibre Package' ($18,490), which gives you the carbon exterior package, carbon inserts in the side skirts, and more carbon on the front wing trim, the mirror housings, the rear wing (which is now fixed) and in the cabin.

There is more, of course, but we'll get to them under our performance, driving and safety sections.

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.

It's not just what's under the bonnet, but what's at the rear axle, too.

But let's start at the front, shall we? Here, a familiar twin-turbo V8 engine lurks, producing a potent 470kW and 900Nm, which is fed through a nine-speed automatic, complete with paddle shifters and several drive modes, including the traction-limiting 'Race'.

But that is then joined at the rear by an electric motor with its own two-speed transmission, and which produces 70kW and 320Nm – or up to 150kW for 10-second blasts under heavy acceleration.

Combine both, and you're tapping into around 620kW and in excess of 1000Nm, enabling a sprint to 100km/h in just 2.9 seconds, and a flying top speed of 316km/h.

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.

Fuel efficiency is surprisingly impressive for a vehicle this big and powerful, with Mercedes claiming 7.7L/100km and 175g/km of CO2 on the combined cycle.

Helping that is a the 6.1kW battery, which delivers just 12km in all-electric driving range, but helps reduce overall fuel use.

This AMG is AC power only, meaning you can't recharge using fast chargers, but the brand says its secret trick is its ability to recharge itself using captured kinetic energy incredibly quickly – largely negating the need to plug in unless you want to unlock that EV range – with Merc suggesting that, on a race track for example, the battery will discharge and charge itself continuously as you're lapping.

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.

There's a lot of big numbers surrounding the Mercedes-AMG GT63S E Performance, but let me throw another one at you – 245km/h.

That was the high score I saw pop up on its digital speedo as the big and electrified Mercedes flew down the main straight at Sydney Motorsport Park (formerly Eastern Creek), before my courage ran out and my foot found the brake.

That kind of velocity is mind-bending in a vehicle this big, and so is the way that power is delivered, with the AMG's big brain deciding how and when to maximise power from the engine and electric motor to deliver a constant surge of torque that shoves you back, and the GT63S E Performance into the future.

But big acceleration is hardly surprising with that much power. What is a little more impressive is how easy this four-door supercar is to wrestle around a racetrack.

Sure, the feeling-out process is a little more involved, as you figure out how and when you'll feel the weight shifting, and as your brain struggles to compute how what's happening is even possible, but after a couple of laps the AMG settles into an easy, flowing rhythm that, while never feeling light on its feet, also doesn't feels like you're piloting a bus.

At least part of that is down to the wizardry on board, like the 'AMG Air Suspension', the rear-axle steering and the limited-slip diff, all of which combine to make the GT63S feel tighter and sharper than it would otherwise.

But it's also partly down to the prodigious power on offer – perfect corner entry and exits are less relevant when you have a cruise missile strapped to your right foot that doesn't just quickly make up for any driver errors, but shrinks the space between corners to the blink of an eye.

Yes, it's heavy, and there isn't much that's pure about the go-fast experience, but it left an ear-to-ear grin on my face, and isn't that priority one for any new AMG?

How does it drive on the road? That I don't know, as this was a track-only drive day. But we will get one on a proper test soon and let you know.

The GT63S E Performance is yet to be crash-tested (probably something about each one costing about the same as small apartment), but it does come pretty comprehensively loaded with safety kit.

That includes the standard 'Driving Assistance Package Plus', which delivers active cruise control, AEB, 'Active Steering Assist', 'Active Lane Change Assist' and nine airbags.

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.

The GT63S E Performance is covered by Mercedes' five-year, unlimited-kilometre warranty, and you can pre-pay your service costs to keep the prices down.

Service pricing for the electrified model is yet to be confirmed.
