Toyota GR Yaris vs Mercedes-Benz A-Class

What's the difference?

The GR Yaris GTS with the Aero Performance Package is a so wonderfully special with its brilliant engineering, mind-blowing dynamics and fun-to-drive nature. The new aero package makes an already angry beastie look furious, making it the perfect enhancement that's also functional.

The only lower marks here are for warranty, fuel use and practicality. But if there was a score for fun it'd be a 10/10.

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.

The GR Yaris exists so that Toyota could go racing in the World Rally Championship. As with many racing series it required Toyota to build a road-going version of their Yaris race car, also known as a homologation vehicle. It’s a good deal, they get to race, you get a race car for the road. And so the GR Yaris was born. 

Wildly different from a regular five-door garden variety Yaris, the GR Yaris is a hand-built three-door hatch with a wider track, wider and lower body and the use of forged carbon and aluminium for lightweight construction.   

The GR Yaris already looks very angry, but the GTS Aero Performance Pack makes it look furious. It adds a huge adjustable rear wing, fender ducts that channel air, a front spoiler lip that aids stability, a giant bonnet scoop to help release air, and rear bumper ducts to reduce drag. 

The GR Yaris’s cabin was redesigned for the 2025 update and that saw the dashboard angled more to the driver much like in a race car, but it's more functional than fancy and it’s all very plain.

Still, we’re not complaining. The seats are lovely and the red stitching is a nice touch but this isn’t a Lexus. It’s supposed to favour function over form and so the design is absolutely fitting. And by function I mean dynamics and not practicality.

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 regular Yaris is small, the GR Yaris is smaller at 3995mm end-to-end and with two fewer doors. As a tall person (I’m 1890mm end-to-end) the space on board is adequate up front with just enough knee, head and elbow room.

The GR Yaris is a four seater with the two rear seats accessed through the front doors. There’s not much room in there for adults and not even my lanky 11-year old would be happy in there. Still if you need to carry three other people, technically you can.

Cabin storage is limited to fairly large door pockets and two cupholders between the front seats. There is a little shelf carved into the dashboard which is great and a small glovebox below it.

Boot space is tiny at 174 litres but again this is a small car with other priorities. 

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.

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.

It still boggles my mind how 221kW and 400Nm is extracted from a 1.6-litre three-cylinder petrol engine but here we are. The GR Yaris has this set up with this output, along with all-wheel drive. 

Thanks to lightweight materials such as forged carbon and aluminium the GR Yaris weighs nothing in car terms - just 1300kg - so acceleration from 0-100km/h is a rapid 5.1 seconds.

I’ve already detailed the juicy engineering bits the GTS Aero Package is fitted with, from the limited slip diff to the adjustable rear wing, and it’s not an exaggeration to say that not many small hatches are this gifted with this kind of genius.

Our test car has an eight-speed automatic, which is easy to drive in city traffic. However, I'd opt for the six-speed manual because if you've come this far you may as well go the whole way.

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.

The GR Yaris is a hungry beastie that eats through its 50L petrol tank fairly quickly and then wants more. Toyota says you should see 9.1L/100km of 98 RON used in the automatic and 8.2L/100km with the manual over a combination of driving conditions. 

Stop-start city driving in traffic saw fuel use increase dramatically to 13.0L/100km in the auto. According to our car's trip computer, my own testing used an average of 14.5L/100km after mainly suburban driving.  

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.

There’s been a multitude of electric cars through the test garage over the past six months and the GR Yaris is like a diamond found in a tub of Lego when it comes to driving.

So much sound. The three cylinder snarls on start up sending vibrations into the cockpit and up through the steering wheel, the transmission can be heard engaging gears, the big brakes creak as they’re released. And we’re hardly even moving yet. There’s so much theatre. It’s all real and I love it!

I even love that in the first 10 minutes of driving, a message appears on the instrument cluster asking that excessive acceleration be avoided while the engine is cool. You don’t get that beautiful inconvenience in an electric car.

But when you can excessively accelerate (on a race track of course, right?) it's wonderful and it's loud. Lift off, and the wastegate lets out a little "weeee!" in excitement.

I don't need to tell you that the GR Yaris handles better than just about anything in this price range and while the ride is firm and speed bumps feel like you’ve hit a gutter I still drove the GR Yaris every day, even to do the school run, because it is so much fun. Meanwhile my hybrid long0term test car looked lonely in the driveaway all week...

Being an automatic makes it easy to drive in traffic and the small size makes finding parking spots quick and simple.

Visibility is good, steering is excellent, the seats are big enough to accommodate me but snug enough to offer good lateral support, too.   

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.

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.

The GR Yaris is covered by Toyota's five-year/unlimited-kilometre warranty which is lacking compared to many other mainstream manufacturers’ seven-year-plus warranties. The good news is that the engine and driveline is covered by an extra two-year warranty.

Servicing is capped at about $300 for the first six visits, although services are six months apart which means that after three years you’ll run out of capped-price servicing.

Still, Toyota’s reputation for reliability does provide some peace of mind. 

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.
