Mercedes-Benz A-Class vs Toyota GR Yaris

What's the difference?

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

Put simply, this is a car we love made better, and if track driving is in your future, this is the GR Yaris you want. 

Whether the changes make it harder to live with is yet to be seen, but if it's fun you're after, the Rallye delivers it by the high-octane bucket load.

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.

It looks almost exactly like the regular GR Yaris, with a couple of minuscule changes that the eagle-eyed will spot. 

For one, there's two new vent openings in the front grille to aid brake cooling, and there's a numbered plaque in the cabin so you know which Rallye you've got (though Toyota concedes this is more of a vanity project than any indication of the numbers actually being limited).

Most noticeable, though, is the bespoke paint colour - a shimmery pearlescent white called Frosted White, which makes the bright-red brake calipers pop. 

Elsewhere, though, its the same swollen, angry-looking hot hatch we've come to know and love.

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

Next question, please. This is a three-door, manual-only performance hatch, so practicality is not really at the top of its to-do list.

In terms of the basics, you get four (two up front and two in the rear) seats, twin ISOFIX attachment points in the back, and a 141-litre luggage space that swells to 737 litres when the 60:40 rear seats are folded flat. 

While the backseat is fairly sparse, with no fold-down centre armrest or cupholders, you do some connectivity options in the vehicle, with a USB-A port and 12-V power outlet. 

The rear seats are fairly tight. My 175cm frame can fit into either easily enough, but you probably wouldn't want to spend too much time back there. 

Conversely, though, the front of the cabin feels spacious enough, and the seats are appropriately figure-hugging for when you're tearing through corners. 

Speaking of which, the steering wheel, gear shifter and pedals are all nicely positioned so that you feel a part of the vehicle, and while the manual gearbox offers rev-matching on the up and downshifts, true heel-and-toe driving is a very real option, too.

Prepare to have your idea of how much you'd pay for a three-door Toyota city car completely rearranged, because the GR Yaris Rallye is not cheap.

How much, you ask? Initially offered at $56,200 drive-away as part of a launch push, the Rallye has now settled at its regular MSRP of $54,500 plus on-roads. 

That's a sizeable step up from the $49,500 (before on-road costs) of the regular GR Yaris, but it's a price increase justified by the extra performance kit.

And a good thing, too, because it shares much of its other equipment with its GR sibling. 

There's a leather-wrapped steering wheel and manual shifter and aluminium pedals, for example. There's a 4.2-inch screen in the driver's binnacle, and there's a second 7.0-inch touchscreen in the centre of the cabin that gets Apple CarPlay and Android Auto, which pairs with an eight-speaker JBL stereo. You also get dual-zone climate control, and keyless entry.

Most important, though, you get more go-fast stuff, like those lightweight alloys, he two Torsen limited-slip differentials (one on each axle) and the retuned suspension.

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.

No change to the powertrain here, but that's no bad thing - I bloody love this engine. 

The turbocharged 1.6-litre, three-cylinder engine develops a whopping 200kW and 370Nm (in a vehicle that weighs just 1280kg, no less), which is fed through a six-speed manual gearbox with up-and-down rev matching, and then funnelled to all four wheel via the GR-FOUR all-wheel drive system.

How much power goes where is up to you, with Rallye equipped with Normal, Track and Sport drive modes that split the power between the front and rear axles to 60/40, 30/70 and 50/50 respectively. 

Toyota says all of that is enough to see the Rallye clip 100km/h in 5.2 seconds.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

Toyota says the GR Yaris Rallye sip a combined 7.6litres/100km, and emit 172 grams/km of C02.

The bad news? The Rallye demands premium fuel to fill its 50-litre tank. 

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.

Short answer? This Rallye takes everything we love about the GR Yaris and makes it better. 

If that sounds like we're waxing lyrical, it's because we are. While our testing was limited to a handful of laps of a race-like circuit, they were enough to feel the most important additions to the Rallye - those twin limited-slip diffs - doing their thing.

Designed to direct the torque to the wheel with the most grip, the system does its best work in cornering, where grunt it sent to the tyre with the most load for extra grip when exiting a bend.

This is a truly exciting hot hatch, full of froth and fizz, and one that you feel intimately connected to when behind wheel. Every moment of acceleration, loss of traction, or wiggle in the rear, is felt in the drivers seat, and it's the kind of vehicle you simply get better at the more time you spend in it.

The brakes are ace, too (356mm front, 297mm rear), and will it's not lightning-fast in a straight line, it's plenty quick through corners. 

How much harsher is the stiffer suspension on a normal road? Is it easy to live with as an everyday driver? Is it too track-focused for suburban life?

Honestly, we don't know. We are yet to drive it on regular Australian roads. But we will, and soon, and we'll update you as soon as that happens.

But in terms of sheer driver fun? The GR Yaris has it in spades.

It certainly hasn't been left behind on the safety front, the Rallye, with six airbags, blind-spot monitoring, a head-up display and a reversing camera.

The tech then steps up, with Toyota's Safety Sense system including AEB, intersection assistance, adaptive cruise control, lane trace assist and road-sign assist.

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.

The GR Yaris Rallye is covered by Toyota's five-year, unlimited-kilometre warranty, with the engine and driveline covered for seven years.

Servicing is required every six months or 10,000kms, and will set you back $260 each for the first six visits.
