Mercedes-Benz A45 vs Cupra Leon

What's the difference?

The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.

There's a lot to like about the updated Leon line-up, but probably not by lots of people. It won't be a best-seller, Cupra doesn't need or even want it to be. What it will do is offer something different, and in the case of the Sportstourer something very rare.

The S and VZx will face stiffer competition in the hatchback markets, primarily from Volkswagen, Audi and even Skoda, and it's hard to pick an area where they really stand out from the competition, apart from the unique styling. Not that they aren't pleasant cars to drive, it's just a crowded market.

Which is why the Sportstourer, especially with its plug-in hybrid powertrain, has a chance to be something that really sets Cupra apart from its rivals. Dynamic, efficient and different, it won’t fit in - and that’s exactly what the brand is hoping for.

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

When I went to pick up the Mercedes-AMG A 45 S 4Matic+ I walked right past it and then like that lost and confused John Travolta in Pulp Fiction internet memes, wandered around before asking where the car was.

That’s because I was looking for something with a gigantic spoiler on the roof and probably hi-vis green with stripes. But the car assigned to me was the A 45 S in its standard form, and the styling is subtle enough for it disappear into a crowded car park like James Bond into a lavish dinner party.

But like Bond, chances are the A 45 S is the most hardcore person in the room, it just doesn’t walk in announcing it to everybody.

Look closely and you'll see that the A 45 S is not just another small prestige car. There’s the 90mm quad exhaust poking out of the chunky diffuser, the giant 'Panamericana' grille, and the angry looking front apron.

Then, there are the 19-inch matt black alloy wheels wrapped in low-profile Michelin rubber and enormous brake discs with their red calipers, all barely contained by the pumped up front wheel guards which are much bigger than those on a regular A-Class.

The cost option my test car wore was the 'Mountain Grey Metallic' paint, but if anything it made the A 45 look even more covert.

The cabin is small but luxurious and sporty with two-tone leather upholstery (the red and black 'Lugano' leather in my test car is a no-cost option), there’s the microfibre-clad AMG steering wheel, brushed aluminium trim, metal-trimmed pedals and the large display panel (it’s actually two screens joined) is also standard.

The A 45 S is a hatchback measuring 4445mm in length, 1850mm wide and 1412mm tall. Not keen on a hatch but want something with similar dimensions? The CLA 45 S is the A 45 S’s four-door twin-under-the-skin and is just as much of a weapon.

And if you want your A 45 S to look more aggressive, you can option the 'AMG Aero Package' which will see a giant rear wing fitted to the roof.

Or you can buy the Edition 1 version of the A 45 S which includes the big spoiler and shouty design bits to makes sure everybody knows you’re the assassin in the room.

Design is a key tenet of Cupra’s ethos, because while it may share Volkswagen mechanical DNA, the Spanish brand wants to really stand apart when you look at or sit inside the Leon.

While it may be the same size as a VW Golf, it certainly doesn’t look or feel like one. Yes, there’s the typical Volkswagen build quality to the fit and finishes, but overall it has a unique Spanish style to it.

On the exterior, Cupra has given the Leon a major visual overhaul with the front end featuring a new-look grille, bumper and headlights. At the rear the tail-lights have been redesigned and now incorporate the logo into a single horizontal light bar that runs the width of the rear.

Inside there’s some new materials, but the most notable change is the introduction of a 12.9-inch multimedia screen. Ambient lightning available on all three models helps to highlight the cabin design.

Along with good performance and handling, part of the appeal of hot hatches is that they’re practical… to a degree. The A 45 S is a small car, but it has four doors, five seats and a boot.

The cabin is small, no doubt about it, but even at 191cm tall I had plenty of room while driving, the seating position is perfect actually, although sitting behind my driving position saw my knees just touching the seat back.

Headroom is getting limited back there, but I still had space. Could you get away with the A 45 S as a family car? I had my family in it for a while, but there’s just the three of us and my son is pre-school-aged. So, a young, small family, yes… until it starts to grow.

Cabin storage is good with two cupholders in the rear centre fold-down armrest along with small door pockets and seat-back nets. Up front there are another two cupholders, giant door pockets, a big split-opening centre console bin and a tray for the wireless charger big enough to fit an iPhone 11 Pro Max.   

Boot space is good at 370 litres. The big shiny CarsGuide suitcase fitted in easily (see images) and apart from the wide-opening of the boot, another hatch power of practicality is that you can fold the rear seats down to open up more cargo carrying space, and in the A 45 S’s case that’s 1210 litres.

I’ve mentioned the wireless charger but there are also four USB-C ports (two up front and two in the rear), back seat passengers also have directional air vents, which is another bonus, along with dark tinted windows (welcome when my son was sitting back there in his car seat).

While we’re talking about two different bodystyles here - hatch and wagon - the front seats are the same. So you are treated to Cupra’s stylish but thoughtful layout, which looks nice but also has good practicality.

The seats themselves are comfortable, even after extended periods behind the wheel, while there’s cupholders, sizeable door pockets, a lidded centre console box and a wireless smartphone charging pad.

The previously mentioned 12.9-inch multimedia screen dominates the centre console, sitting proudly at the top of the fascia. Unfortunately, Cupra (like Volkswagen) has fallen to the modern trend of ‘touch controls’ rather than physical buttons.

Not to sound like an old man yelling at clouds, but these touch-sensitive sliders are simply not as user-friendly, especially in a moving vehicle, as a traditional physical button or dial. While the multimedia system is easy to use, especially with Android Auto or Apple CarPlay fully integrated, adding dials for the stereo (on/off and volume) and the climate control would have been great.

Otherwise, the 12-speaker Sennheiser sound system with subwoofer and 390W amplifier sounds great, offering a premium in-car entertainment experience to match the Cupra’s price and positioning.

As for space in the back, which is obviously where the hatch and Sportstourer vary. There isn’t a lot to split them in terms of passenger space. These are both small cars, so neither offer the kind of room you’d get from an equivalent-sized SUV. The real difference is the cargo capacity, the hatch pair offer 344L (or 888L with the rear seats down) whereas the Sportstourer has a more generous 470L/1045L.

Knowing that hatchbacks and wagons aren’t big sellers and Cupra’s desire to stay boutique rather than mainstream, the line-up is relatively simple.

The Leon S kicks off the range at $46,990 (all prices listed exclude on-road costs) and comes with 18-inch black and silver alloy wheels, LED headlights, keyless entry and ignition, heated sports bucket seats, tri-zone climate control and a six-speaker sound system with Apple CarPlay and Android Auto.

The Leon VXz starts at $64,990 and includes 19-inch black and copper alloy wheels, multi-link rear suspension, adaptive dampers, front locking differential, upgraded brakes, quad exhaust and Cupra drive modes. There’s also leather-appointed seats and a 12-speaker Sennheiser sound system.

The VZe Sportstourer completes the line-up priced at $69,990 featuring unique 19-inch black and copper alloys, LED headlights and tail-lights, a power tailgate with handsfree opening and black roof rails. Inside it gets leather-appointed sports seats, heated front seats and steering wheel, tri-zone climate control, native navigation, Apple CarPlay and Android Auto plus the 12-speaker Sennheiser stereo.

There may be hot hatches out there which look wilder than the Mercedes-AMG A 45 S 4Matic+ but do they have the most powerful four-cylinder engine ever to go into a mass-produced car? Nope, but the A45 does: it’s a 310kW/500Nm turbo-petrol four.

It doesn’t sound as angry and gravelly as the previous A 45’s engine but it has more grunt (an extra 30kW/25Nm) and is claimed to catapult the hatch from 0-100km/h in 3.9 seconds.

The '4Matic' part of the name indicates the hatch is all-wheel drive and the '+' means it’s a more sophisticated version of the system which allows all of the drive to be sent to one axle, if need be.

What need would that be? The need to drift, of course, which should be up there with other human rights such as clean air, fresh water and free speech.

Yep, the A 45 S comes with 'Drift Mode' (for the racetrack, of course), along with a 'Launch Mode' for perfect-every-time transitions to warp speed.

Changing gears gunslinger-fast is an eight-speed dual-clutch automatic transmission.

The three Leon models all feature a different powertrain, as each is targeting a distinctly different buyer.

The Leon S is powered by a 110kW/250Nm 1.5-litre turbocharged petrol engine with mild-hybrid assistance. 

The Leon VZx gets a more potent 2.0-litre four-cylinder turbo-petrol engine that makes 221kW/400Nm, to put it right at the heart of the hot hatch market.

The Leon VZe Sportstourer manages to combine efficiency with performance, with a 1.5-litre turbo-petrol engine paired to an electric motor to make an efficient 200kW and 400Nm.

The one thing all three have in common is a seven-speed dual-clutch transmission and front-wheel drive.

Mercedes-AMG says the 2.0-litre, turbo-petrol, four-cylinder in the A 45 S should use 8.9L/100km after a combination of open and urban driving.

My fuel test saw me drive 131km of urban and country roads, plus some motorway sections, and needed 16.9L of premium unleaded petrol to fill the 51-litre tank back to full.

That comes to 12.9L/100km, which is thirsty, but my driving style may have contributed significantly to that high figure.

Naturally, the three different powertrains provide three very different fuel economy numbers.

The mild-hybrid system in the Leon S allows it to use just 5.4L/100km, which provides a theoretical range of up to 833km thanks to its 45-litre fuel tank.

The VZx is the thirstiest member of the range, not surprisingly, using 7.6L/100km. With its 50-litres tank it has a theoretical driving range of approximately 650km.

Finally, the Sportstourer VZe manages a claimed 0.4L/100km on paper, thanks to its 20kWh battery providing up to 121km of electric-only driving range. Obviously achieving that claimed figure in the real world is incredibly difficult (as it is with any PHEV) but we still managed to use just 2.4L/100km on our mostly extra-urban test drive, which is still a good return.

I wasn’t lying in the introduction to this review. The previous A45 was a pretty intense driving experience. The ride felt brutal, the exhaust note screamed and crackled like somebody had set a wheelie bin full of fireworks alight.

And then there was the sweating. I seemed to sweat a lot driving it and there was nothing wrong with the climate control, that just happens to me when I’m under pressure and excited.

So, has the new-generation A 45 S 4Matic+ gone all soft and quiet on us? No, but things have been toned down a tad.

The exhaust note is not as gruff or loud, and even in 'Sport +' and 'Race' mode it’s still quiet enough to pull into a driveway at night without making enemies of your neighbours.

And the ride is also not as harsh, although even in 'Comfort' mode my wife still found it verging on too firm.

The performance and dynamics, however, felt as sharp as ever.

Acceleration is supercar quick at 3.9 seconds. My gawd, you needed a Ferrari F40 to do that in the mid-’80s, and even now the new Mercedes-AMG GT S supercar gets there only a tenth of a second earlier, and it has a twin-turbo V8.

Top speed for the A 45 S is electronically limited to 270km/h. But hot hatches aren’t really about straight-line speed, they’re more about bent-line speed. You know, corners.

So, I took the A 45 S on the twisty roads I take anything that calls itself sporty. The agility of the A 45 S is outstanding thanks to a rigid chassis that handles a change in direction as quickly and easily as you can turn your head.

The brakes bite hard when they have to, and the all-wheel drive hatch scrambles tenaciously out of corners.

A racetrack is really the best place to truly test a serious sports car's limits and our own James Cleary did just that when he drove the A 45 S at its international launch.

As a daily driver, though, for somebody who occasionally likes to get into it on a curvy road the A 45 S is comfortable enough to live with, but hard enough to remain engaging and dynamic when you get the chance to have a squirt.

Obviously there are three very different variants in the Leon range, with three different powertrains and two different body styles, and yet there is a familiar feeling between all three when you’re behind the wheel.

This is arguably the ‘most Volkswagen-y’ element of the Cupras, with the solid, stable Volkswagen underpinnings coming through. This is, of course, not a criticism, but rather highlights the positive connections between Cupra and its parent company, which has allowed it to make an immediate impression on the Australian market.

However, it also means the Leons feel so familiar that they don’t leave you with a unique impression and driving character.

For example, the VZx is almost too good, too quick and too clinical. It lacks the excitement and engagement rival hot hatches offer, notably the Hyundai i30 N and Honda Civic Type R, but instead compensates by just being really capable.

Obviously, that may not be seen as a negative by everyone and for those who want that sort of engaging, dare I say ‘fun and edgy’, driving experience the Leon VZx may not be precisely what they are looking for. Still, the engine is potent and even the lack of all-wheel drive doesn’t dampen its performance abilities too significantly compared to the likes of a VW Golf R or Audi S3.

The Leon S offers a different proposition, a warmed up hatch, rather than something hot. On that front it delivers, providing a well-mannered drive but without the punch of the VZx.

The Sportstourer is arguably the pick of the range, with its combination of sharp driving dynamics and very efficient powertrain. At no point do you feel like Cupra compromised its sporty intent to make the Sportstourer save fuel. Instead, the PHEV powertrain offers plenty of performance when you need it but is otherwise quiet and efficient the rest of the time, helping it to sip fuel at a much lower rate than its Leon hatchback alternatives.

The Cupra trio come loaded with plenty of safety features including 10 airbags for excellent passive protection plus autonomous emergency braking, front and rear cross-traffic alert, blind spot warning and driver fatigue monitoring.

For convenience and safety there’s also adaptive cruise control, front and rear parking sensors and even self-parking.

As the Leon has had no major structural changes, the original 2021 five-star ANCAP rating still applies. However, it should be noted that ANCAP updated its testing protocols in 2023, so that five-star rating is different to a five-star rating applied since then.

The Mercedes-AMG A 45 S 4Matic+ is covered by a five-year/unlimited kilometre warranty.

Servicing is recommended at 12 month/20,000km intervals. Servicing is capped at $850 for the first year’s visit, $1200 for the next and $1600 for the third.

All three Leons are covered by Cupra Australia’s standard warranty, which covers the first five-years/unlimited kilometres. Which is good, especially for a new and more premium brand, even if it’s obviously short of the best-in-market.

Servicing is required every 12 months/15,000km, whichever comes first, and Cupra is offering a servicing pack special until the end of 2025, of $1990 for five years. That works out to an average of $398 per year.

Cupra is expanding its dealer network in Australia too. The Leon drive event we attended began at the newly-opened Cupra Macarther in Sydney’s growing west. There’s also a new dealership at Melbourne’s Essendon Fields.

Of course, one of the key advantages that Cupra has over many other new brands to Australia is its Volkswagen/Audi connections, which allows its models to be serviced at those dealerships as well. That provides a much larger footprint for customers to find somewhere convenient to service their car, which cannot be underestimated.
