Mercedes-Benz A45 vs Fiat 500E

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.

A fun, funky EV which will no doubt appeal to lovers of Italian style, but also one which struggles a little on the range and price front.

Still, there’s no doubt that electrification has improved the Fiat 500 formula.

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.

It looks, well, it looks like a Fiat 500.

It’s actually bigger in every dimension than an ICE cinquecento, but it doesn’t really look like it, which is a good thing.

The 17-inch wheels look great, and big against the very small Fiat, and I like the hidden doorhandles, which make the already smooth-looking 500’s flanks look a little smoother still. But I can take or leave the little DRLs up front that are meant to act as little illuminated eyebrows for the headlights, which come over a bit too cutesy.

But I think the highest compliment I can pay it is that it looks like a regular Fiat 500 — one of the most successful reincarnations of a timeless design ever — and not some modern, eco-friendly version that would have killed the look. 

In the cabin, however, it’s definitely a more modern affair, with the big screen, the horizontal push-button gear selector, and the nifty push-button door openers.

Still, it’s all pretty familiar Fiat 500, only a little nicer, even if some of the plastics are far too hard and scratchy for a vehicle this expensive.

There are five colours available: Ice white, Onyx black, Rose gold, Ocean green and Celestial blue.

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).

The 500e is 29mm taller, 61mm longer and 56mm wider than the current ICE Fiat 500 (now 1529mm, 3631mm and 1683mm respectively), and it rides on a longer wheelbase, too .

That means more front-seat room and head room, but there’s still not oodles of space in the four-seat cabin, and especially in the back, where things are pretty tight.

I’m 175cm tall, and my head touches the ceiling in the back, and if I had another full-size human in the back with me, I’d want it to be someone I know well, because we’d be well and truly aquatinted by the time we got to our destination.

The front seats are more accomodating, but there is a strange tightness to the pedal area for the driver. It’s so tight, in fact, that when you rest your left foot, you have to be careful not to accidentally clip the brake pedal when driving.

The boot is a small 185 litres, too. But you’re not buying this for practicality perks, are you?

The 500e is not cheap by modern small EV standards — we’re looking at you, China — but it does arrive in one well-equipped trim level, called La Prima, with paint the only available option.

It's also, quite shockingly for anyone who has driven an ICE Fiat 500 lately, stacked with some truly high-tech kit.

 There’s heated seats for the first time ever, for example, and there’s 10.25-inch central screen with Apple CarPlay and Android Auto, and wireless charging.

There’s a digital driver display, too, plus there’s faux-leather on the seats and dash, a panoramic glass sunroof and fancy push-button front doors (though with a mechanical back-up lever hidden in the door pockets should something go pear shaped).

Outside, you’ll find 17-inch alloys, as well as LED lightning all around, including the DRLs, and there’s keyless entry and push-button start, too.

But, and it’s a significant but, the 500e lists at $52,500 before on-roads , which — when you consider its size, battery and range — really edges it into the premium EV space.

A similar-sized EV from China can be had for under $40k, which means you are going to have to really love the 500e to drop that extra $15k or so.

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.

A single front-mounted electric motor delivers the power here, with 87kW and 220Nm on offer. Enough, Fiat says, to knock off 100km/h in 9.0 seconds. But it does feel quicker than that in real life, thanks to the way electric vehicles deliver their power.

There’s the usual EV single-speed gearbox, too, with power sent to the front wheels.

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.

The Fiat 500e’s 42kWh battery provides a smallish 311km driving range on paper, but when we got in it was more like 290km at 96per cent charged. A city car, then, rather than a long-distance hauler.

When it does come time to charge, you’re set up for 85kW DC fast charging which should take you from zero to 80 percent in 35 minutes. 

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.

This is the probably the best-driving example of the Fiat 500 I’ve ever climbed into. Sure, it’s not quite as engaging as self-shifting a perky little manual, but it’s smoother, easier and more comfortable, and a whole lot better than ICE vehicles fitted with Fiat's odd dual-logic automatic gearbox.

The EV transition genuinely suits the little Fiat, admittedly sapping a little character, but also thoroughly modernising the drive experience, with smooth, constant acceleration, sharp-enough steering and a ride that’s mostly settled, only really becoming crashy over the bigger road imperfections.

The small dimensions here also help the EV reincarnation. Yes, it’s heavier than you might expect, weighing in at 1290kg (tare), with the batteries adding several hundred kilograms to the equation, but the 500e still doesn’t feel overly heavy, with the little Fiat remaining pretty light on its feet.

There are three drive modes on board, including the catchy Sherpa mode (because it will help get you where you’re going), which, when you’re running low on battery, kills the climate control and anything else it needs to preserve range and get you home. 

But you can’t shake the feeling that the 500e is a little expensive for such a specialist tool. It’s unashamedly a city car, but one that will cost you more than $50k, and which doesn’t feel quite premium enough in the cabin to justify that asking price.

There’s a heap of active safety stuff on board (again, unusual for a 500), with active cruise control, traffic sign recognition, front, rear and side parking sensors, blind-spot monitoring, AEB with pedestrian and cyclist detection, and more.

Still, the 500e only secured a four-star ANCAP safety rating, scoring just below the five-star cut off in Adult Occupant Protection, Child Occupant Protection and Safety Assist, with a lack of a centre airbag not helping.

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.

The fly in Fiat’s ointment is its ownership proposition, with a three-year, 150,000km warranty now way below par in Australia these days, even if the battery is covered for the standard eight years. 

Servicing is every 12 months or 15,000kms, and will cost $250 a pop for the first eight years, which is commendably cheap.
