What's the difference?
Audi would probably prefer you not to realise this, but the five distinct versions of S4 and S5 on the market all pertain to a single performance and equipment formula spread across five different bodystyles.
Yes five, and this has been the case for more than a decade, with the S4 sedan and Avant wagon, A5 two-door Coupe, convertible Cabriolet and five door liftback Sportback all representing vastly different shapes for you to choose from, with the same underpinnings. This simply echoes the A4 and A5 ranges they’re based on of course, and BMW clearly thought it was a good idea too, given the 3 and 4 Series ranges were split into individual lines at the start of last generation.
Mercedes-Benz offers a similar array, minus the liftback, but is happy to wrap the whole lot under the C-Class label.
So, given that the A4 and A5 range scored a mid-life update a few months ago, it’s only logical that the changes flow on to the performance S4 and S5s, with the top-tier RS4 Avant following suit.
We’ve covered the latter in October, and now it’s the turn for the former, and CarsGuide was among the first to drive the updated S4 and S5 ranges at their Australian media launch last week.
The B10 isn’t Leapmotor’s first car in Australia - the C10 has been here for more than a year now - but for many it might bring about the first time they hear about the Chinese brand.
The 2026 Leapmotor B10 lands in Australia promising to be the most European of its Chinese compatriots, with the brand’s connection to Stellantis giving it access to other brands under the company umbrella like Alfa Romeo, Maserati and Peugeot.
At its local launch, we get behind the wheel in scorching south-east Queensland to find out if that holds true for this electric small SUV, and to see if the B10 can bring with it a better first impression than the already-arrived mid-size C10.
The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.
I’ll be a shame if the B10 doesn’t sell well, because it doesn’t suffer from many of the downfalls of its compatriots and its price is extremely competitive for what you get.
As a comfortable smallish SUV, it meets par, and it’s on the better side of tech when it comes to cars from China, and it doesn’t have any major on-road red flags.
You really wouldn’t be disappointed with this having paid $40K, just skip the base model and go for the Design.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
The S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year.
This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look.
The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.
The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car.
Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.
On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.
Right after we praise the B10 for its value, we need to talk about its looks. A slight drop in tone as the second Leapmotor to land in Australia looks an awful lot like the first, and it’s relatively bland.
It’s not ugly, but it’s not particularly inspiring and there’s not much character to this little electric SUV.
It’s got a very upright silhouette at the front with a slightly sloping roofline at the rear, so the overall shape is appealing, but the lack of distinct features makes the B10 an anonymous commuter for now, especially with its similarities to the C10.
You can tell them apart by the C10’s slightly larger size if they’re near each other, or the B10’s more in-line headlight bar, where the C10’s have a ‘droop’ at the sides.
The large section of black at the lower half of the front is also unappealing, though darker colours like the optional 'Starry Night Blue' or 'Dawn Purple' (both $990) blend into it better than standard 'Light White'.
To its credit, at least the B10 doesn’t fall victim to the design crutch of adding trim and plastic for no reason.
In terms of the specifics, the B10 is 4515mm long, 1885mm wide and 1665mm tall with a 2735mm wheelbase, making it quite the large small SUV.
Inside, the cabin looks and feels roomy thanks to the test car’s light interior, decent windows and the light from the sunroof, as well as the fact the EV powertrains are compact and generally don’t interfere with cabin space.
Materials aren’t all scratchy hard plastic, though it is dotted around, and the general look of the B10 inside feels more premium than its price would have you thinking, despite the simplicity of the layout and design.
The biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.
It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.
There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.
I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for.
The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.
Getting into the B10 requires a minor annoyance - unlocking and locking the car requires a keycard to be tapped on the drivers’ side mirror like you're scanning to access your floor in a hotel elevator.
There’s an app that adds a fair bit of functionality, but having to whip your phone out ahead of jumping in the car is also irritating.
Once you’re in, though, the space inside the B10 is well laid-out, even if much of its functionality is crammed into the big central touchscreen - it’s always ‘points off’ for a lack of physical buttons in this section of a review.
Once you’re used to it and have sorted out your personal settings on the multimedia software, it becomes more natural and less distracting, though Apple CarPlay and Android Auto would occasionally lag in the car on test.
The good news is they now exist for the brand in the B10, with the Leapmotor C10 still lacking the vital in-car mirroring tech.
The ergonomics and interior space work well, generally, with comfortable pews and good vision, plus decent spaces to keep things out of the way. The phone charger being in a very visible and accessible position might tempt some naughty screen-keen drivers, and being in the sun without a vent for cooling while charging means your phone will get proper hot.
The second row is extremely spacious, belying the fact this car is classified as a small SUV. Oodles of legroom and enough headroom for a tall adult means the B10 outguns rivals in terms of good options for parents (note the B10’s extremely strong 95 per cent child safety score from ANCAP, too) or anyone who needs to cart humans around regularly.
Behind the second row is a 490L boot, which becomes 1475L when the second row is folded down.
There’s space under the floor for cables and messy bits, but unfortunately no spare wheel, just a tyre repair kit, so more points off for that.
As I mentioned above, the S4 and S5 line-up are in many ways the same, but also different, and these differences result in a price span of $20,500 between the S4 sedan and the S5 Cabriolet.
The former is now $400 cheaper with a list price of $99,500, with the also-$400 cheaper S4 Avant not far beyond at $102,000.
The S5 Sportback and Coupe are now $600 more expensive at an equal list price of $106,500, while the swish folding soft top of the S5 Cabriolet pushes it up to $120,000 (+$1060).
Equipment levels are consistent across all five variants aside from the S5s getting Matrix LED headlights as standard and one inch larger 20-inch wheels.
Key details include Nappa leather trim with front sport seats with seat heaters and massage function, a Bang & Olufsen sound system which spreads 755W across a total of 19 speakers, brushed aluminium inlays, head-up display, coloured ambient lighting, tinted windows and metallic paint.
Over the past 12 months, the S5 Sportback has proven to be the most popular of the five variants by far, accounting for 53 per cent of sales, with the S4 Avant next in line at 20 per cent, the S4 sedan making up 10 per cent, and the S5 Coupe and Cabriolet combining to make up the remaining 17 per cent.
Talking about the price may well be us highlighting the Leapmotor B10’s strongest point right up top, because you can get into one for less than $40K, drive-away, before the end of March 2026.
While regular pricing for the B10 starts from $37,888, before on-road costs, for the base Style and $40,888 for the kitted-out Design LR, Leapmotor has a limited-time deal starting from $38,990, drive-away, for the B10 Style and $41,990 for the Design LR. LR for Long Range, by the way.
That runs until the end of March, 2026, but even its standard pricing is impressive for what you get.
The entry-grade B10 Style comes with plenty of kit, including an 8.8-inch LCD driver display and large 14.6-inch central multimedia touchscreen, a wireless phone charger, auto climate control, a panoramic sunroof with retractable shade, heated mirrors, auto LED headlights, a set of 18-inch wheels, surround-view parking cameras with dashcam recorder capability, over-the-air (OTA) updates and Level 2 advanced driver assistance (ADAS).
That’s a list of inclusions that can, on paper, rival much more expensive models.
The Design LR, for not much more money, adds heated and ventilated synthetic leather seats with electric adjustment (six-way for the driver, four-way for the passenger), a heated steering wheel, a 12-speaker sound system, ambient lighting, a power tailgate, tinted privacy glass, LED tail-lights and auto folding mirrors.
You’d hate to be in the product planning team of a legacy manufacturer trying to put together a competitive spec for a small electric SUV to sell in Australia against that.
Even other small electric SUVs from China come with much smaller batteries or fewer features around the $40K mark, like the MG S5 EV Essence RWD with its 49kWh battery ($42,990 D/A) or the base Geely EX5 Complete FWD ($40,990 BOC) and the higher Inspire variant is $4000 more.
Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.
The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels.
There’s only one powertrain option for the Leapmotor B10, a single, rear-mounted electric motor that produces 160kW and 240Nm, which makes the electric SUV good for a claimed 0-100km/h time of 8.0 seconds in both variants.
Top speed is a claimed 170km/h, also regardless of the variant.
Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km.
All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.
All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.
Leapmotor claims the B10 will, from its LFP battery of either 56.2kWh for the Style or 67.1kWh for the Design LR, draw 17.2kWh/100km or 17.3kWh/100km, respectively under WLTP testing.
The result is the Style offering up a 361km WLTP-tested driving range, and the Design LR a more useful 434km.
While we were unable to properly confirm this claim on the launch, the trip computer after a mix of highway driving and more spirited back-road testing displayed a figure of 13.5kWh/100km, while the previous 1447km of driving had reportedly measured in at 14.7kWh.
Charging from 30 to 80 per cent takes approximately 20 minutes regardless of spec and battery size. The smaller battery can be charged via DC fast-charging at a maximum 140kW, and the larger at 168kW. Both max out at 11kW under AC charging.
The S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.
I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode.
My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension.
Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.
Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.
The Leapmotor B10 was developed with testing at Stellantis’ European proving ground in Italy. This is because despite Leapmotor being its own brand within China, its international operations are a joint-venture between itself and Stellantis.
There are some on-paper shreds of evidence for this, a rear-wheel drive layout and a claimed 50/50 weight distribution help, but get the B10 on the road and it’s clear this isn’t a car that’s relying entirely on price, a long list of features and some showroom shine to sell.
After the initial familiarisation that comes with many new electric cars, particularly from China, the Leapmotor B10 becomes easy to settle into a rhythm with, especially if you turn off some of its more intrusive ADAS features like lane-keep, driver monitoring and speed limit warning. The latter can sometimes get a limit wrong, and though the B10’s chimes aren’t audibly overbearing, they are persistent.
While the B10 doesn’t excel in any areas on the road, it doesn’t fall down significantly in any either.
Its suspension soaks up bumps relatively well, and despite some vibrations on rougher roads the B10 is pretty comfortable. The tyres it rides on as standard, however, are rather noisy, so if there’s an opportunity to swap out the Linglong defaults to something better, we’d advise it.
The tyres also squeal rather quickly when cornering, not necessarily because the B10 is about to let go, but just because the weight of the car appears to be pushing on the front outside tyre in cornering.
The B10 holds up better than\ a family car really needs to in dynamic driving, but we wouldn’t be doing mountain runs or track days in one.
There’s a little body roll in corners, but not nearly as much as has been in other models riding on the apparently soft suspension preferred in China.
The steering, braking and acceleration all have a mild vagueness to them, but once you’re honed in they’re all predictable. The steering can be adjusted for weight, and its lightest setting is too light, while the acceleration feels lethargic in its lowest setting and too aggressive in its highest.
There’s not a lot of regenerative braking strength, but it’s enough to help regulate speed once you’re used to how mildly it comes in - again, depending on your preferences and settings.
The good news here is that the B10 is easy to drive, and only very serious road bumps on fast corners unsettled it on test - the kind you’d expect to upset any car.
All S4 and S5 variants boast an impressive array of safety features, but there’s some interesting points when it comes to ANCAP ratings. Only four cylinder A4 models (therefore not S4) were given a maximum five star rating when tested according to less stringent 2015 standards, but all A5 variants (therefore S5) aside from the Cabriolet carry a five star rating based on the tests applied to the A4. So officially, the S4 is not rated, but the S5 Coupe and Sportback are, but based on the A4 rating that doesn’t apply to the S4. As with most convertibles, the Cabriolet is simply not rated.
The airbag count totals eight in the sedan, Avant and Sportback, with dual front airbags, plus side and curtain airbags covering front and rear.
The Coupe drops the rear side airbags, while the Cabriolet also drops curtain airbags, meaning there’s no airbags for rear seat occupants. The roof is made of folding fabric, there has to be some safety compromise.
Other safety features include front AEB that works up to 85km/h, adaptive cruise control with traffic jam assist, active lane guidance and collision avoidance assist that can automatically swerve, a 360 degree camera system, rear cross-traffic alerts, exit warning that can prevent you opening a door into an oncoming car or cyclist, and pre sense rear that can detect an impending collision from behind and prepare the seatbelts and windows for maximum protection.
The Leapmotor B10 was bestowed a five-star ANCAP rating in early February 2026 under the body’s most recent criteria.
There are seven airbags, including an important centre airbag, plus the B10 boasts 17 ADAS systems with 12 cameras and sensors helping monitor the road, surroundings and the driver.
As mentioned, those systems can be a little intrusive sometimes, but less than other new models from brands new to Australia.
The B10’s list of safety features includes multi-collision braking, collision sensors, an emergency data recorder, the aforementioned dashcam-style surround-view recording system, belt pretensioners, plus all the elements of the ADAS suite Leapmotor calls 'Leap Pilot'.
This includes adaptive cruise and lane centring, lane departure warning and emergency intervention, collision avoidance and warnings, blind-spot detection, rear cross-traffic alert and brake, speed assist, and driver monitoring and distracted driver warnings.
For baby capsules and child seats there are three top tethers across the second row with ISOFIX anchors on the two outer positions.
Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.
Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.
The B10’s post-purchase prospects are generally solid, though Leapmotor’s six-year, 160,000km warranty is an area where it falls short of rivals which are offering longer, unlimited kilometre warranties.
The battery is covered for eight years or 180,000km, whichever comes first, which is pretty par for an EV.
Servicing is capped-price for the first eight years, with each service costing $370 on average. The eight-year span makes it pretty appealing, per 12-month interval or every 20,000km.
There are currently 20 dealers across the country, though more are coming, while Leapmotor also offers eight years of roadside service.
