Mercedes-Benz CLA45 vs Xpeng G6

What's the difference?

The new CLA 45 S has knockout performance to match its knockout looks, neither of which are much of a surprise given the ingredients involved.

That said, it is far from perfect, with questions raised over its value and practicality. And for those reasons, we’d be buying the A 45 S hatch instead.

Is the new CLA 45 S worth such a hefty premium over its non-S predecessor? Tell us what you think in the comments below.

You never know quite what to expect when you jump into the first model from a brand-new brand, but the XPeng G6 was a pleasant surprise. And at this price, with these features, it should really give Tesla Model Y shoppers something to think about.

There’s simply no mistaking the CLA 45 S from its CLA siblings. It’s angry and stylish, at the same time.

Up front, Mercedes-AMG’s signature 'Panamericana' grille insert is large and in charge, flanked by adaptive 'Multibeam' LED headlights that incorporate sinister-looking daytime running lights (DRLs).

The real action, however, is happening below, where the AMG body kit starts to come into frame. It’s delightfully chunky and highlighted by cavernous side air intakes, which hint at the sledgehammer residing beneath a bonnet featuring prominent power domes.

Around the side, the CLA 45 S does its best impersonation of a coupe, with a sloping roof line and a curvaceous glasshouse. It also brings the aggro with a particularly sporty set of 19-inch alloy wheels, which flank pointy side skirts.

At the rear, the CLA 45 S again hints at its performance level, this time with a bootlid lip spoiler, although look past its LED tail-lights and you’ll find the star of the show, a furious diffuser that houses the quad 90mm tailpipes of the AMG sports exhaust system.

Inside, the CLA 45 S is pretty special. While the CLA certainly provides the building blocks, it goes a step further with a number of unique touches.

Your eyes are immediately drawn to the wickedly cool 'Dinamica'-trimmed AMG Performance steering wheel, which not only has paddle-shifters, but also features two ‘display buttons’ that make adjusting vehicle settings on the fly super easy.

Then there are the front sports seats, which are covered in Lugano leather upholstery alongside the armrest door inserts, while artificial cow hide trims the upper dashboard and door shoulders.

Hard plastics? You’ll need to look lower than the soft-touch middle dashboard to find them, as they are primarily confined to the lower sections of the cabin. And yes, some of the switchgear is very cheap for a six-figure performance car.

One personal bugbear, though, is the liberal use of gloss-black trim for the centre stack and console. Not only is it a fingerprint magnet, but it scratches easily, too. The brushed stainless-steel and silver accents elsewhere are nice, though.

While stainless-steel sports pedals also help to make the CLA 45 S stand out from the CLA crowd, it is otherwise a carbon-copy of its siblings, which is no bad thing.

Of course, the headline act is the pair of 10.25-inch displays, with one a touchscreen that is partially concealed by the steering wheel, while the other is a digital instrument cluster.

The former delivers the now-familiar 'MBUX' multimedia system, which is still at the cutting edge when it comes to functionality, especially with its always-on natural voice recognition, which is as good as it gets, albeit not perfect.

There are, of course, more input methods, with two small touchpads located on the steering wheel, while a larger item sits on top of the centre console, supported by a palm rest. There are also shortcut buttons and physical climate controls.

There’s more than a little Tesla Model Y in the XPeng’s exterior design, with the two sharing the same kind of soft-edged, swept-back SUV styling. 

It helps make the XPeng look familiar and inoffensive, and while I wouldn’t go so far as to call it ground-breaking, I think it has enough exterior flourishes to break up the body work, and I don’t mind the way it looks, and the way it sits on those big alloys.

Inside, it’s a spacious and pretty stylish space. This giant screen is super responsive, and is easy enough to navigate, with the key functions (like climate) glued to the bottom of the screen so you don't have to paw through menus to access them. The idea begins to fail when you have Apple CarPlay or Android Auto active, though, as you have to revert back to the car's home screen to access anything.

The XPeng uses its steering wheel controls to access air-con fan and temp controls as a kind of shortcut, but confusingly they change to distance adjustment when you’ve got the cruise control on. An easier, and much better solution would be to bring back buttons.

I also don't love the stalk-style gear selector, which doubles as a cruise control activator, and, with a double pull, as your autonomous helper. It just feels super old-school in a vehicle this modern.

What is a massive win though is the driver screen. Tesla fans can scream minimalist aesthetics all they want, but the drive experience is simply better when you can see your speed and other key info right in front of you.

Measuring 4693mm long, 1857mm wide and 1413mm tall, the CLA45 S is actually similar in size to a C-Class but not quite as practical.

Cargo capacity is pretty good, at 460L, but can be increased via the 40/20/40 split-fold three-seat rear bench stowed – an action that can be performed via the boot’s manual release latches, although it doesn’t tumble forward by its lonesome.

Speaking of the boot, four tie-down points are on hand for to help loose loads alongside two side storage nets. Bulkier items will have to contend with a tall load lip. That said, the boot’s aperture is much wider than before, which is good news.

In-cabin storage options are okay, with the glove box decently sized and the map pockets of the net variety, while the central bin is fairly average, although it does house two USB-C ports.

There’s also a standard sunglasses holder and a cubby in front of the centre console’s two cupholders. It isn’t that useful, though, as the wireless smartphone charger takes up most of space alongside a USB-C port and a 12V power outlet.

The front door bins can accommodate two regular bottles each, while their counterparts in the rear take only one apiece. That said, the second row does have a fold-down armrest with another pair of (flimsy) cupholders.

Rear occupants don’t have a whole lot of room to play with, though. Legroom behind my 184cm driving position is pretty decent, at around four centmetres, but headroom is not. In fact, it’s non-existent sitting upright, with the panoramic sunroof not helping matters.

Toe-room is also at a premium alongside precious footwell space, which is reduced by the tall transmission tunnel. As such, the second row is best for up to two adults or three children at a time.

And if there are three occupants abreast, they’ll have to compete for the two USB-C ports, which are located in a fold-out cubby below the central air vents at the rear of the centre console.

For reference, child seats can be fitted in the second row thanks to top-tether and ISOFIX anchorage points, although both are only available for the outboard seats.

At 4753mm in length, 1920mm in width and 1650mm in height, the XPeng fits into the fast-growing mid-size electric SUV space. 

And it ticks a lot of practicality boxes, like with its 571-litre boot, swelling to 1374 litres with the seats folded. But its real party trick is in the back seat, where the space is properly massive. 

I have another mid-size SUV, powered by a petrol engine, at the moment and our baby seat presses against the back of the passenger seat. In this it feels like I could fly a kite in the space between them.

It’s the same for passengers, too. Honestly, the real estate on offer is massive, and that includes for the middle-seat rear passenger, where the lack of a bulky tunnel eating into legroom means adults can sit there comfortably.

There's a pull-down divider separating the back seat that's also home to two cupholders, and there are twin USB connections, as well as air vents (though no temp controls).

There's no spare tyre, though, which means fiddling with the repair kit should you get puncture, or waiting for roadside assist.

Okay, first things first – what the hell is XPeng? It's been around for about 10 years in China, but only made its way to Australia last year. It was founded by some former car company execs and tech tycoons — one of whom is telecommunications billionaire He Xiaopeng, which is where that name comes from.

Anyway, this one is the XPeng G6, which launched in Australia with two trims – the Standard Range, which is $54,800, before on-road costs, and the one we’ve tested, the Long Range, which is $59,800. The difference is in the battery size, of course, but we’ll get to that in a minute. 

As of now, the new Model Y can be ordered for $63,400 for the Standard Range or $73,400 for the Long Range, which makes the XPeng a whole heap cheaper.

Outside, you get LED lighting all around (including the DRLs), a massive glass roof, auto door handles, an auto-opening boot, a V2L connection, which allows you to use your XPeng’s battery to power whatever you plug in and big 20-inch wheels wrapped in Michelin rubber.

You also get some cool high-tech features, accessed through the XPeng app, like the ability to drive your car out of tight parking spots remotely.

Inside, there are synthetic-leather seats that are heated, a heated steering wheel, dual-zone climate, a massive 18-speaker sound system (with speakers in the headrest), wireless charging and two very handy screens — a responsive 15-inch central screen with Android Auto and Apple CarPlay, and a 10.2-inch digital dashboard.

There’s also more safety stuff than you can shake a crash test at, but we’ll come back to that in a second.

The CLA45 S is motivated by the most potent series-production four-cylinder engine yet.

The 2.0-litre turbo-petrol unit punches out an astounding 310kW of power at 6750rpm and a significant 500Nm of torque from 5000-5250rpm – a marked 30kW/25Nm improvement over its non-S predecessor.

It’s also worth noting Mercedes-AMG performed “torque shaping” to make the new engine’s output delivery (or curve) akin to that of a naturally aspirated unit. This attitude also led to a screaming redline of 7200rpm.

An eight-speed dual-clutch automatic transmission is responsible for swapping gears, while Mercedes-AMG’s fully variable '4Matic+' system sends drive to all four wheels, although it does have a 'Drift Mode' that effectively disengages the front axle.

With the help of standard launch control the CLA 45 S sprints from a standstill to 100km/h in four seconds flat, while its top speed is electronically limited to 270km/h.

This G6 is a rear-wheel drive affair, with a single electric motor housed at the rear axle. It produces 190kW and 440Nm in Standard Range form or 210kW/440Nm in Long Range guise, which don’t sound like massive numbers — especially given the 2.0-tonne-plus weight of this XPeng – but it gets up and moving just fine.

The 100km/h sprint is a claimed 6.2 seconds, while the top speed is 200km/h.

Fuel consumption on the combined-cycle test (ADR 81/02) is 8.9 litres per 100 kilometres for the CLA 45 S, while its claimed carbon dioxide emissions are 202 grams per kilometre. Both are pretty keen given the level of performance on offer.

In our real-world testing, we averaged 12.0L/100km over 270km of driving evenly split between city traffic and highways. This result was somewhat inflated by some ‘spirited’ driving but is certainly something we can learn to accept.

For reference, the 51L fuel tank in the CLA 45 S takes 98 RON premium unleaded petrol at minimum.

The Long Range version of the G6 nabs a 87.5kWh battery (compared to 66kWh in the Standard Range), unlocking a claimed driving range of 570km. 

The official power use figure is 17.5kWh/100km, but I did a fair bit of driving on all sorts of roads and my number was more like 14kWh.

When it does come time to charge, the G6 is set up for 280kW DC fast charging which means, should you find the right fast charger, a 10-80 per cent charge should arrive in just 20 minutes. Home charging will take a lot longer, of course – we’re talking overnight plugged into a regular wallbox.

When it comes to sheer driving pleasure, the CLA 45 S is a huge step-up over its non-S predecessor.

Of course, the 2.0-litre turbo-petrol four-cylinder engine will steal all the headlines, and rightfully so; it’s the most potent unit in its class by some margin.

In reality, it absolutely slaps. Simply put, acceleration is addictive, and not just because of the outputs, but also the way in which they’re delivered.

The CLA 45 S does its best impression of natural aspiration, and I can’t help but award it an automotive Oscar.

Don’t get me wrong, performance is still strong down low (despite a hint of turbo lag), with it progressively building into, and through, a hard-hitting mid-range before reaching a knockout top end that you’ll want to revisit time and time again.

That said, it does take two to tango, and what a dancing partner the eight-speed dual-clutch automatic transmission is.

It’s almost flawless, with its gear changes stereotypically super quick but uncharacteristically buttery smooth at the same time.

Responsiveness is another strong point, although it does sometimes have difficulty recognising when the fun is over, as it can hold onto the short lower gears for a little longer than necessary.

And despite our initial fears, the CLA 45 S is still very, very vocal, with its sports exhaust system serving up plenty of aural pleasure, albeit not quite as much as the original CLA 45.

The soundtrack is booming and is complemented by plenty of pops on downshifts and the overrun as well as frightening crackles when aggressively up-shifting . But these theatrics require the Sport Plus drive mode to be engaged, which opens up an all-important exhaust valve.

Given the level of performance on offer, you’d be right to assume the CLA 45 S has a firm ride, but it’s actually better balanced than most.

The 'AMG Ride Control' sports suspension on hand consists of MacPherson-strut front and multi-link rear axles with three-stage adaptive dampers, which progressively stiffen things up.

However, all is relatively comfortable, even in the stiffest setting. In fact, only sharper edges are felt. It’s more than liveable, especially considering the benefits of the trade-off.

Speaking of which, the CLA 45 S loves to eat up corners. Handling is more or less neutral when pushing hard, at which point its 1687kg kerb weight starts to be felt.

Nonetheless, body control is very strong, partially thanks to the reinforced chassis, with only a hint of roll encountered when cornering with intent.

A lot of the credit has to go the fully variable 4Matic+ all-wheel drive system with rear torque vectoring, which provides outstanding grip, even in the poorest of conditions.

In fact, it bestows such confidence you'll want to push harder to try and find the limits of adhesion. A staggering effort.

The CLA 45 S isn’t without its flaws, though, with the electric power steering on tap good but not great.

It’s speed-sensitive and has a variable ratio, which mean it’s pleasingly light in hand at low speed and noticeably heavier at high velocity, with the latter exacerbated when playing with the available drive modes.

Either way, it’s nice and direct and provides a good amount of feedback through the wheel, but we feel Mercedes-AMG could’ve taken it even further in these two departments to really mix it up with genuine sports cars.

What isn’t half-baked, though, is the 'AMG High Performance braking system', which consists of 360 x 36mm front and 330 x 22mm ventilated discs with six-piston fixed and single-piston floating red callipers respectively.

This set-up washes away speed with ease, instilling the driver with even more confidence when tackling a winding road, while pedal feel is good. Yep, the CLA 45 S decelerates nearly as well as it accelerates.

How much you love your time behind the wheel of the XPeng G6 comes down to what you're looking for from your mid-size electric SUV.

Speed and sportiness? There's not much of either. But it does serve up tons of space and technology, surprising refinement and a calm and cosseting ride.

And I think you can mount a pretty solid argument that all of that is pretty important in a mid-size SUV, more so than the ability to carve corners.

I did some solid driving in the G6, including a round trip from Sydney to the start of the NSW South Coast, taking in every road type and surface imaginable, and XPeng proved super comfy, pretty quiet and very, very easy the entire time.

Sure, it's not one of those EVs that makes the scenery blur when you put your foot down. Its outputs and acceleration are a bit more user-friendly than that. But it also doesn't ever feel underpowered, with the plenty of poke away from the lights and even some in reserve for freeway overtakes at 110km/h.

The steering, even in its 'Dynamic' mode, is fairly soft, and you can never magic away the weight of the XPeng in corners, where that compliant suspension does allow for some roll, but it also doesn't feel entirely disconnected from the road below in that disconcerting way some vehicles can.

So, if comfort is mission critical in your SUV space, the XPeng delivers.

Oh, and I know that big screens aren't that uncommon these days, but the multimedia unit in the XPeng is a treat. It's super fast, even when scrolling across maps, and it's relatively user friendly, too.

The XPeng G6 wears a maximum five-star ANCAP safety rating from assessment in 2024, owing mostly to a flood of active safety features that arrive as standard, including AEB (with pedestrian, backover, cyclist, motorcycle and crossing detection), lane departure warning, lane keep assist, speed sign recognition, driver monitoring and more.

But it could also lay claim to a unique record – the first Chinese EV in which the safety systems don't make you want to make you pull your hair out with their incessant chiming and bonging.

Only on the freeway, where an intermittent chiming incorrectly warned me I was leaving my lane, were the safety systems at all overzealous. Otherwise, they were entirely liveable.

If a crash is unavoidable, the airbag count runs to seven (dual front, front side, side curtain and front centre) and multi-collision brake is standard, to minimise the chances of a secondary crash following an initial impact.

Like all Mercedes models, the CLA 45 S comes with a five-year/unlimited-kilometre warranty, which sets the standard in the premium market. Better yet, five years of roadside assistance is also bundled in.

CLA 45 S service intervals are every 12 months or 20,000km, whichever comes first. A three-year/60,000km capped-price servicing plan is available for $3750, which is not cheap. That said, its pricing can be reduced by $750 if paid upfront alongside the vehicle.

I'm scoring the regular warranty offering here, which is five years or 120,000km, with the battery covered for eight years or 160,000km. Keep an eye out for deals, though. At the time of writing XPeng was offering a 10-year warranty on both, for example.

Service intervals are 12 months or 20,000km. The cheapest individual service is $238, but over five years the total cost is $2064, averaging out to more like $410 per year.
