What's the difference?
Think of a Mercedes-AMG and the first words that spring to mind are probably not - understated, efficient and restrained. And yet those are probably the best words to describe the all-new C 43.
Of course, before we go any further it’s important to note that the C 43, even in its previous six-cylinder guise, was never meant to be as wild, raucous or powerful as the C63 flagship - that’s simply not its role in the AMG line-up.
But even so, this new model is a dive into fresh territory for the brand and puts a very different spin on the AMG sports sedan as we know it.
This is a four-cylinder model, complete with a Formula One-derived electric turbocharger, so it lacks the sound and fury you expect from something carrying the ‘AMG’ badge - but that doesn’t mean it’s a bad car, as we’ll explain.
Spoilt. That's what we are. If you're in the market for a hot hatch, you can have your pick of German-built and French ones from as little as $27,000. There isn't a dud among them now that the VW Polo GTI has had a bit of an update and you can pick and choose your style. Audi's S1 is aiming to be king of the kids with its stiffly-priced S1.
Set the finances aside and consider for a moment what's on offer. As it turns out, a lot.
The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.
This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

Cars this small shouldn't be this fast and useable at the same time, but the Audi S1 is. It isn't without its problems - the ride is harder even than the Fiesta ST which might weary some prospective buyers.
It's also a bit difficult to justify the price - in its basic form it's missing a few creature comforts that you'd expect in a $50,000 car - reversing camera, high-res screen, that sort of thing.
However, in the hot hatch world, those things don't matter. It has the bragging rights, the tech and the outright blinding speed to take on the bonkers Focus ST and equally zany Megane RS. And even the Audi S3.
Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.
It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.
To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.
Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.
The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.
In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.
The A1 is so small it starts to strain Audi's design language. When you cram on the S-style bumpers and raccoon-eyed trim on the hatchback, it's starts to look a bit busy.
It isn't quite a shrink-wrapped A3 - Ingolstadt's designers know better than that - but it's full of Audi design cues, such as the strong, light-catching character lines, distinctive LED daytime running lights and fondness for big wheels.
Inside is along the themes of the A3, with what are becoming Audi's trademark; round eyeball air-con vents, the manual fold-down screen familiar to Q3 owners (but smaller) and a good clear dash. The handbrake jars slightly as it feels cheap to hold and wobbles a bit.
The S Sport seats are big and comfortable, and the top half of the backs are capped in plastic, which was colour-coded on our car. The rear passengers will certainly get an eyeful of whatever terrifying hue you've chosen, so choose wisely.
Despite the five doors, the back seats are occasionals, like the Mini the A1 is gunning for, and the boot is very small, but okay for shopping for couples or singles.
We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.
It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.
However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.
In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.
There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.
The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.
Starting at $49,900, Audi S1 is by far the priciest of the small-hatch based hotties, at least until Mini's madcap JCW arrives. This price is just almost double that of VW stablemate's forthcoming 2015 Polo GTI.
Standard on the manual-and-five-door-only S1 is a ten speaker stereo, climate control, ambient lighting, remote central locking, cruise control, satnav, headlight washers, auto headlights with xenon low beams, partial leather seats, leather-bound steering wheel, auto wipers and rear parking sensors.
Our Misano Red ($990 option) came with two extra packs. The Quattro Exterior Package ($3990) adds bi-xenon headlights with red trim, red brake calipers, spoiler, quattro logos on rear doors (ahem!) and five-spoke 18-inch alloys that are part matt black, part polished.
The Quattro Interior Package ($2490) adds S Sport front seats with Nappa leather and red backrest capping with quattro logo (ugh), more nappa around the cabin with contrast stitching, flat bottom steering wheel and red rings on the air vents.
There's an S Performance Package that brings the best of these two packs together for $4990, saving about $1500 and the embarrassment of the quattro logos.
Our test car also had aluminium air vents ($220), black contrasting boot lid ($300) and black roof ($720).
The A1 is so small it starts to strain Audi's design language
The grand total is a sobering $58,610. There's a couple more options that'll easily pop you over $60,000.
Audi's MMI is dash-mounted in the A1 as there's no room on the narrow centre console. As ever, it works well and doesn't take much getting used to. The satnav is a bit grainy on the smaller screen but is otherwise a competent unit.
Sound is from a ten-speaker stereo and you can stream across Bluetooth or plug in a memory card. The sound was good but the system did take a while to find the phone whenever we came back to the car.
The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.
But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.
While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.
The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.
To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.
Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience.
It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.
The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).
Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.
This is where the action is. The S1's tiny body packs a 2.0-litre turbocharged four-cylinder producing 170kW and 370Nm of torque. The S1 will streak to 100km/h in 5.9 seconds thank to the traction aid of quattro all-wheel drive.
All Audi S1s come with a six-speed manual
Despite a pretty solid hammering during its week with us, including more time than we'd have liked in Sydney traffic, the stop-start function helped deliver a pretty reasonable 10.2L/100km, however that's a long way over claimed 7.1L/100km.
All Audi S1s come with a six-speed manual, so dual-clutch haters can save the whining. The only downside from not having a self-shifter is the ECU can't deliver the boy racer farts, parps and crackles of the other S cars.
Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.
You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.
The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.
However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.
As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.
The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.
And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.
Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine.
Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.
In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement.
The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.
Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.
Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.
If you're buying the S1 as a comfortable urban runabout with a cool badge, you're half right. While the seating for front passengers is certainly supportive, the hard suspension tune will ensure you're well aware of road surface imperfections.
The S1 is a rocket
Thankfully, what it missed out on in the ride department it makes up for in every other way - the S1 is a rocket. The 2.0-litre turbo jammed under the bonnet has almost no lag and is paired with a slick six-speed manual that is terrific fun to manhandle through the gears.
The way the S1 picks up speed when it's on boost is addictive and licence-endangering. A flattened accelerator in second or third will obliterate just about anything this side of $100,000 and you'll be having more fun in this than big brother S3 because the chassis is more adjustable and there's a bit more life.
You can hear the turbo sing to accompany the bassy exhaust growl. Hit the massive brakes hard and the car remains stable even over rutted roads. Turning the wheel brings almost-instant turn-in, mashing the throttle again a fun little wriggle. It's superb.
It's tremendous fun point-to-point on a twisty road
You'll have to be a bit patient with the throttle to get the wriggle, though - give it too much too early and it will want to push wide, the quattro system shuffling power around to try and quell understeer while the electronic diff fiddles with the braking system to do the same thing. It gets there in the end, but you're better off meting out the power with your right foot for maximum rewards.
It's tremendous fun point-to-point on a twisty road - despite being a bit heavy for its size (1415kg), it's as chuckable as the next best thing, the Fiesta ST.
The C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.
Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.
Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.
The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.
While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.
Six airbags, stability and traction control, ABS, brake assist and distribution all add up to a five star ANCAP rating.
